Surat receives between 5.5 and 6.2 peak sun hours per day — among the highest of any major Indian city — and sits entirely within the DGVCL (Dakshin Gujarat Vij Company Limited) service territory. Put those two facts together and you have one of the most financially compelling rooftop solar markets in India. A 3 kW on-grid system costs ₹1,02,000–₹1,47,000 after the ₹78,000 PM Surya Ghar subsidy, generates 430–550 kWh/month, and pays back in 3–4 years. After payback, electricity is effectively free for the next 20+ years.
This guide is the only reference you need before going solar in Surat. It covers system sizing, accurate 2026 costs, the DGVCL subsidy and net metering process, commercial solar economics for Surat’s textile and diamond industries, how to verify a quality installer, and the eight most expensive mistakes Surat homeowners make.
Direct answer. Installing solar in Surat in 2026 costs ₹1,80,000–₹2,25,000 gross for a 3 kW system. After the ₹78,000 PM Surya Ghar subsidy, net cost is ₹1,02,000–₹1,47,000. Payback runs 3–4 years for households in the DGVCL ₹5.80–₹6.65/kWh tariff slab. The entire process — application to subsidy receipt — takes 45–75 days with a DGVCL-empanelled installer.
Why Surat Is One of India’s Best Solar Cities
Surat has a rare combination of factors that make rooftop solar more financially attractive here than in most Indian cities.
Solar irradiation. At 21.2°N latitude, Surat’s Global Horizontal Irradiation (GHI) averages 5.5–6.2 kWh/m²/day over the year, according to the MNRE Solar Energy Resource Atlas. The dry season from October through May delivers consistent clear-sky days. Even during the monsoon (June–September), Surat’s short, intense rainfall periods mean more cloud-free hours per monsoon day than coastal cities further south. Over a full year, Surat’s solar resource is comparable to Jodhpur and meaningfully better than Mumbai, Pune, or Hyderabad.
High DGVCL electricity tariffs. DGVCL’s 2026 residential tariff escalates sharply with consumption:
- Slab 0–50 kWh/month: ₹4.65/kWh
- Slab 51–200 kWh/month: ₹5.50/kWh
- Slab 201–400 kWh/month: ₹6.00/kWh
- Above 400 kWh/month: ₹6.55/kWh
A Surat family with two or three air conditioners, a refrigerator, washing machine, and regular daytime appliance use typically consumes 300–600 kWh/month — landing squarely in the ₹6.00–₹6.55/kWh range. Every kWh your solar system generates instead saves you ₹6.00–₹6.55. That is a strong financial case before factoring in any subsidy.
Ideal rooftop architecture. Surat’s housing stock — particularly in areas like Adajan, Vesu, Katargam, Udhna, and Althan — is dominated by flat-rooftop bungalows and row houses. Flat roofs allow flexible panel orientation and are structurally straightforward for installation. Most Surat homes can accommodate a 3–8 kW system with minimal shading from adjacent buildings.
Active PM Surya Ghar participation. DGVCL has processed thousands of PM Surya Ghar applications in Surat since the scheme launched. The PM Surya Ghar Muft Bijli Yojana portal tracks real-time applications across all DISCOMs. DGVCL’s feasibility approval averages 7–14 working days — faster than several other state DISCOMs. The subsidy disbursement process through DGVCL is well-established, with DBT transfers typically arriving within 30 days of commissioning.
Strong installer competition. Surat’s large industrial solar market has attracted dozens of MNRE-empanelled EPCs. This creates genuine competition on price and quality, which benefits residential buyers — provided you verify credentials before signing.

System Sizing for Surat Homes: 1BHK to 4BHK
Choosing the right system size is the most important decision in a solar installation. Too small and you miss out on savings; too large and you over-export at the low DGVCL feed-in tariff rate of ~₹2.25–₹2.75/kWh instead of consuming at ₹5.50–₹6.55/kWh. The goal is to size your system to cover 90–100% of your daytime consumption.
Sizing method. Use your last 12 months of DGVCL electricity bills. Take your average monthly units consumed. Divide by 30 days, then divide by the number of effective solar hours (use 5.0 for a conservative Surat annual average including monsoon). Add 10–15% margin for inverter losses and soiling. That is your target system capacity in kW.
Typical sizing for Surat household types:
| Home Type | Typical Monthly Consumption | Recommended System | Roof Area Needed |
|---|---|---|---|
| 1 BHK (no AC) | 80–150 kWh | 1–2 kW | 8–15 sq. m |
| 2 BHK (1 AC) | 150–280 kWh | 2–3 kW | 15–22 sq. m |
| 3 BHK (2 AC) | 280–450 kWh | 3–5 kW | 22–38 sq. m |
| 4 BHK (3+ AC) | 450–700 kWh | 5–7 kW | 38–55 sq. m |
| Villa / independent house | 500–900 kWh | 6–10 kW | 48–80 sq. m |
Monthly DGVCL bill to system size: If your average monthly bill is ₹1,500–₹2,500, a 2 kW system is likely right. If your bill is ₹2,500–₹5,000, look at 3–4 kW. Bills above ₹5,000/month generally justify 5 kW or larger, especially if you have EV charging or plan to add it.
The subsidy sweet spot. The PM Surya Ghar subsidy caps at ₹78,000 for systems 3 kW and above. Installing exactly 3 kW captures the maximum subsidy. Installing 5 kW also gets ₹78,000 — the extra 2 kW is at your full cost. This makes 3 kW the best value-per-rupee-of-subsidy if your consumption allows it.
What if I consume more than a 3 kW can cover? Install the system size your consumption justifies. The economics still work — at ₹6.00–₹6.55/kWh, a well-sized 5 kW or 7 kW system pays back nearly as fast as a 3 kW, even without additional subsidy.
For a deeper look at sizing, our home solar system size guide covers the full methodology with consumption calculators.
Solar Installation Costs in Surat: 2026 Price Breakdown
Understanding solar costs requires separating four things: gross system cost, subsidy, net cost after subsidy, and actual savings. Many vendors quote only “cost after subsidy” — which looks attractively low — without being transparent about the gross price and whether it is competitive.
What a complete system includes. The prices below cover: ALMM-listed monocrystalline PERC panels, BIS-certified string inverter, galvanised steel mounting structure (flat roof ballasted), DC and AC cabling with conduit, DCDB and ACDB protection, earthing system, DGVCL net metering application fee, PM Surya Ghar portal application, 5-year workmanship warranty, and first-year AMC. See our solar panel cost breakdown for how these components are priced individually.
2026 Surat solar installation cost table:
| System Size | Gross Cost | PM Surya Ghar Subsidy | Net Cost After Subsidy | Monthly Generation | Annual Savings (₹5.80 avg) |
|---|---|---|---|---|---|
| 1 kW | ₹65,000–₹80,000 | ₹30,000 | ₹35,000–₹50,000 | 140–170 kWh | ₹9,744–₹11,832 |
| 2 kW | ₹1,25,000–₹1,55,000 | ₹60,000 | ₹65,000–₹95,000 | 280–340 kWh | ₹19,488–₹23,664 |
| 3 kW | ₹1,80,000–₹2,25,000 | ₹78,000 | ₹1,02,000–₹1,47,000 | 430–510 kWh | ₹29,928–₹35,496 |
| 5 kW | ₹3,00,000–₹3,75,000 | ₹78,000 | ₹2,22,000–₹2,97,000 | 716–852 kWh | ₹49,877–₹59,270 |
| 10 kW | ₹6,00,000–₹7,50,000 | ₹78,000 | ₹5,22,000–₹6,72,000 | 1,432–1,704 kWh | ₹99,754–₹1,18,598 |

On-grid vs. hybrid systems — which is right for Surat?
| Feature | On-Grid System | Hybrid System (with Battery) |
|---|---|---|
| System cost (3 kW) | ₹1,80,000–₹2,25,000 gross | ₹2,80,000–₹3,60,000 gross |
| PM Surya Ghar subsidy | ₹78,000 (for solar portion) | ₹78,000 (for solar portion) |
| Power during outage | No — grid-tied, shuts off | Yes — battery provides backup |
| Best for | Areas with reliable DGVCL supply | Areas with frequent cuts, or businesses needing uptime |
| Payback period | 3–4 years | 5–7 years |
| Battery life | N/A | 8–12 years (Li-ion), 5–7 years (lead-acid) |
| Recommended for Surat | Most homeowners — DGVCL is reliable | Factories, hospitals, critical loads |
For most Surat homes, an on-grid system is the right choice. DGVCL’s grid reliability in Surat city is generally good. Hybrid systems make sense for commercial applications, homes with critical medical equipment, or areas on the urban fringe with less stable supply.
Real numbers — 3 kW in Adajan, Surat
Family of four, 3 BHK, two ACs, monthly bill ₹4,200. After 3 kW installation at ₹1,98,000 gross, ₹78,000 PM Surya Ghar subsidy, net cost ₹1,20,000. Monthly bill drops to ₹350 (fixed charges only). Annual saving ₹46,200. Payback: 2.6 years. System investment returns over ₹9 lakh over 25-year panel life.
PM Surya Ghar Subsidy Process for DGVCL Consumers in Surat
The PM Surya Ghar Muft Bijli Yojana gives Surat homeowners up to ₹78,000 paid directly into their bank account — not a discount from the vendor, not a voucher, but an actual bank transfer. The only condition: you must use an MNRE-empanelled installer registered on the PM Surya Ghar portal, and you must be a residential DGVCL consumer. Our detailed guide to getting the ₹78,000 subsidy for solar in Surat covers the complete eligibility criteria.
Step-by-step PM Surya Ghar application process for DGVCL (Surat):
- Register on pmsuryaghar.gov.in — create your account with mobile number and Aadhaar-linked OTP. Have your DGVCL consumer number ready (10–12 digits, found on your electricity bill as “Grahak No” or “Consumer No”).
- Select DGVCL as your DISCOM — in the state/DISCOM selection, choose Gujarat → DGVCL. Do not select Torrent Power even if you previously had a Torrent connection; verify your current DISCOM on your latest bill.
- Choose your system capacity — enter the system size in kW. For most Surat homes the optimal choice is 3 kW (maximum subsidy) or the size matching your consumption if larger.
- Select an MNRE-empanelled vendor — only vendors who appear on the PM Surya Ghar portal’s vendor list can process your subsidy. Ask any vendor you contact to confirm their MNRE empanelment number.
- Upload required documents — latest DGVCL electricity bill (clearly showing consumer number and registered address), Aadhaar card of the electricity account holder, property ownership proof (sale deed, property tax receipt, or registered rent agreement), bank passbook front page or cancelled cheque (account must be in the electricity account holder’s name), and one passport-size photograph.
- DGVCL feasibility approval — DGVCL reviews transformer loading, your sanctioned load versus proposed system size, and technical infrastructure in your area. Approval typically arrives in 7–14 working days. In some Surat localities DGVCL may conduct a site visit as part of feasibility.
- Physical installation — your empanelled installer installs the panels, inverter, mounting structure, and electrical connections. For a 3–5 kW residential system, this takes 1–2 days. Panels must carry BIS certification and inverters must be BIS-certified with anti-islanding protection.
- DGVCL post-installation inspection — DGVCL’s inspection team visits within 7–15 working days after you report completion. They verify panel BIS certification numbers, inverter compliance, wiring standards, earthing, and system capacity.
- Net meter installation — DGVCL replaces your existing single-direction meter with a bidirectional net meter that tracks both import (consumption from grid) and export (solar sent to grid) in separate registers.
- Commissioning certificate — DGVCL issues the official commissioning certificate. Your system is now live and generating.
- Subsidy DBT — ₹78,000 is transferred directly to your registered bank account within 30 days of the commissioning date.
PM Surya Ghar subsidy rates (DGVCL Surat, 2026):
| System Capacity | Subsidy Amount |
|---|---|
| 1 kW | ₹30,000 |
| 2 kW | ₹60,000 |
| 3 kW and above | ₹78,000 (maximum) |

DGVCL Net Metering in Surat: How It Works
Net metering is the billing mechanism that makes rooftop solar economically viable for Surat homeowners. Without it, your solar system would only be useful during the hours you are at home and consuming power. With net metering, the DGVCL grid acts as a virtual battery: you push excess daytime solar production into the grid and draw it back in the evening, with your bill reflecting only the net difference.
Our comprehensive net metering in India guide covers the national framework, but here is how DGVCL specifically handles it in Surat.
How DGVCL net metering billing works:
- Your bidirectional meter records two numbers: units imported from the grid and units exported to the grid from your solar system.
- DGVCL’s monthly bill charges you for (units imported − units exported) at your applicable tariff slab.
- If you export more than you import in a given month, the surplus units roll forward as a credit to the following month.
- At DGVCL’s annual settlement period (typically March/April), any remaining export credits are settled at GERC’s approved feed-in tariff — approximately ₹2.25–₹2.75/kWh in 2026.
- Fixed monthly charges (demand charges) apply regardless of solar generation — typically ₹150–₹400/month depending on your sanctioned load.
Practical design implication. Because exported units earn only ₹2.25–₹2.75/kWh while self-consumed units save you ₹5.50–₹6.55/kWh, a system sized to consume most of its generation is significantly more valuable than an oversized system that exports heavily. A 3 kW system generating 470 kWh/month on a household consuming 420 kWh/month is near-ideal. A 7 kW system generating 820 kWh/month on the same household exports 400 kWh at a low rate — poor economics.
DGVCL net metering application requirements: After installation, DGVCL’s net metering application requires the commissioning test report from your installer, the DGVCL inspection clearance, your consumer number, and the inverter technical specifications sheet. Your empanelled installer should handle this paperwork — confirm this before signing any contract. Also review solar commissioning Gujarat for what the technical inspection involves.
Important — DCR vs. non-DCR panels and subsidy eligibility
PM Surya Ghar subsidy requires BIS-certified panels. For government and PSU projects, Domestic Content Requirement (DCR) panels are mandatory. For residential subsidy under PM Surya Ghar, non-DCR panels are eligible as long as they are BIS-certified. Choosing the wrong panel type does not void residential subsidy but affects tender eligibility for commercial projects. See our DCR vs. non-DCR panels guide for the full distinction.
The Surat Solar Readiness Score: 5 Factors That Determine Your Outcome
Before committing to a solar installation, assess your home against five factors. This is Heaven Green Energy’s proprietary Surat Solar Readiness Score (SSRS) — a structured pre-purchase framework that identifies whether your installation will hit projected savings targets or fall short.
Each factor scores 0–20 points. A score of 80–100 means your installation should hit or exceed projected returns. 60–79 means proceed but address the gaps. Below 60 means address the issues before installing or accept reduced returns.
Factor 1 — Roof Area (0–20 points)
Each kW of solar needs approximately 8–10 sq. m of unobstructed, structurally sound roof space. Score 20 if your available area supports a system sized to your consumption. Score 10 if you can fit 60–80% of your ideal system. Score 0 if available area is less than 8 sq. m (limits you to 1 kW or less).
Surat context: Most 3 BHK bungalows in Vesu, Adajan, or Althan have 80–150 sq. m of roof — no constraint. Multi-storey apartment buildings with shared terraces are the challenge: shared roofs require society NOC and proportional allocation between flat owners.
Factor 2 — Sanctioned Load (0–20 points)
DGVCL will not approve a solar system larger than your sanctioned load (the maximum load on your meter). Most Surat homes have sanctioned loads of 3–7 kW for residential connections. Score 20 if your sanctioned load comfortably exceeds your planned system size. Score 10 if they are approximately equal — installation is possible but DGVCL may scrutinise closely. Score 0 if your sanctioned load is less than your planned system — you must either downsize the system or apply to DGVCL for load enhancement first.
Factor 3 — Grid Zone and Transformer Capacity (0–20 points)
DGVCL will check transformer loading in your area during feasibility review. Overloaded transformers can delay or block approval. Score 20 if you are in a residential area of Surat with established solar penetration (transformer upgrades typically already done). Score 10 if you are in a newer development area where transformer loading is uncertain. Score 0 if you are in an area where multiple neighbours have recently applied — there may be a transformer queue.
Factor 4 — Shade Assessment (0–20 points)
This is the single most underestimated factor in Surat installations. Score 20 if your roof has unobstructed south/southwest sky view from 9 AM to 4 PM year-round. Score 10 if you have partial shading (water tank, parapet wall) affecting less than 20% of panels. Score 0 if you have significant shading from a taller adjacent building, large trees, or overhead electrical infrastructure — shading reduces output dramatically and may invalidate the financial case entirely.
Factor 5 — Budget and Financing (0–20 points)
Score 20 if you can pay the net cost after subsidy upfront from own funds — no interest cost, fastest payback. Score 15 if you are using a solar loan at 8–10% interest — payback extends by 1–2 years but remains financially positive. Score 5 if you are financing at above 12% — the interest cost significantly erodes returns. Score 0 if you cannot fund even after subsidy without high-cost credit — the financial case does not work.
Interpreting your SSRS: Add up your five scores. 90–100 = excellent candidate, install now. 75–89 = strong candidate, address minor gaps. 55–74 = possible, but get a thorough site assessment first. Below 55 = address root causes before investing. Heaven Green Energy conducts a full SSRS assessment as part of every free site visit — contact us to schedule yours.
Commercial Solar in Surat: Textile and Diamond Industries
Surat is home to two industries with enormous electricity intensity: the textile power loom and processing sector, and the diamond cutting and polishing industry. Both operate at DGVCL commercial and industrial tariffs that make solar even more attractive than the residential case.
DGVCL commercial and industrial tariffs (2026): Surat’s textile units and diamond factories typically pay ₹7.50–₹9.50/kWh on time-of-day commercial tariffs, plus demand charges based on sanctioned kVA. Solar generation during business hours — exactly when these industries operate — offsets the most expensive grid units. The Gujarat Energy Development Agency (GEDA) administers industrial solar approvals and empanelment in Gujarat.
Textile industry. Surat’s power loom sector clusters around Katargam, Udhna, Pandesara, and Sachin GIDC. A typical 20-loom power loom unit consumes 15,000–25,000 kWh/month. A 50–100 kW rooftop solar system can offset 30–60% of daytime consumption. At ₹8.50/kWh average industrial tariff, a 100 kW system generating 14,000–17,000 kWh/month saves ₹14–₹17 lakh annually. Gross system cost: ₹55–₹75 lakh. Payback: 3–4 years with accelerated depreciation benefit. Commercial solar installations are also eligible for 80% accelerated depreciation in the first year under Section 32 of the Income Tax Act — a significant additional benefit for taxpaying businesses.
Diamond industry. Diamond polishing factories in Surat’s Varachha, Sachin, and Sarthana areas run precision machinery with sensitive power requirements. Hybrid solar systems with automatic voltage stabilisation and smooth inverter switching are standard for diamond polishers. System sizes range from 20–150 kW depending on factory size.
Commercial net metering under DGVCL. Commercial and industrial solar systems can access DGVCL’s net metering under GERC’s commercial net metering framework. The economics are: you self-consume at ₹8.50+/kWh savings and export surplus at ₹2.50/kWh. This makes oversizing industrial systems expensive — size to self-consumption as with residential systems.
Key difference from residential solar. Commercial installations do not qualify for PM Surya Ghar’s ₹78,000 subsidy (residential-only scheme). However, GST on solar equipment is 5–12% depending on components, and businesses can claim input tax credit on the GST paid. Between ITC, accelerated depreciation, and high tariff savings, commercial solar ROI in Surat routinely exceeds 25–30% per year. Discuss commercial solar specifics with our Surat solar team.
How to Choose a Solar Installer in Surat
Surat’s active solar market means you will receive quotes from a range of installers — from large established EPCs to local electricians with a sideline in solar. The quality gap between them is enormous. Choosing wrong means panels that underperform by 15–25% for 25 years, or a net metering application that never gets processed, or a subsidy that never arrives.
The five verification steps before signing any contract:
Step 1 — Confirm MNRE empanelment. Any installer claiming to process PM Surya Ghar subsidy must be empanelled on pmsuryaghar.gov.in. Ask for their empanelment number and verify it on the portal yourself. Non-empanelled installers cannot process your subsidy — full stop.
Step 2 — Check DGVCL familiarity. Ask the installer to walk you through the DGVCL feasibility and net metering process in detail. A competent installer will know DGVCL timelines, inspection requirements, and the consumer number format. Vague answers indicate limited experience with DGVCL specifically.
Step 3 — Verify panel and inverter brand. Tier-1 panels from Waaree, Adani Solar, Goldi Solar, or Vikram Solar are the standard for Surat installations. Any installer offering no-name panels at unusually low prices is compromising on equipment that will affect generation for 25 years. Similarly, inverters should be BIS-certified and from established brands — Growatt, SolarEdge, SMA, Delta, or equivalent.
Step 4 — Ask for installation references in Surat. A credible installer will have references in Surat — not Ahmedabad or Vadodara. Ask for three to five recent customer names and contact numbers. Call them. Ask specifically about DGVCL net metering timeline and whether the subsidy arrived on time.
Step 5 — Get itemised quotes. Request a quote that itemises: panel brand, model, and quantity; inverter brand, model, and capacity; mounting structure type and material; DC cable length and gauge; DCDB and ACDB specifications; earthing details; application fees (net metering, DGVCL); and warranty terms separately for equipment versus workmanship. A quote that gives only a total price or a “price per kW” without itemisation is a red flag.
For context on panel quality decisions, our DCR vs. non-DCR solar panels guide explains the key equipment distinctions.
Common Mistakes Surat Homeowners Make When Going Solar
These eight mistakes collectively account for most of the bad solar outcomes in Surat. Each one is avoidable.
Mistake 1 — Choosing a vendor solely on lowest price. A 10% lower quote often reflects a 25-year underperformance gap in panel quality, skipped earthing, or no actual MNRE empanelment. The cheapest quote rarely represents the cheapest cost of ownership over 25 years.
Mistake 2 — Oversizing the system to maximise generation. A 7 kW system on a home that consumes 350 kWh/month exports 500+ kWh monthly at ₹2.50/kWh instead of saving it at ₹6.00/kWh. The oversized system pays back years later than an appropriately sized one.
Mistake 3 — Skipping the shade assessment. A 5% improvement in the view angle from the roof can look irrelevant on paper but destroys 15–30% of annual generation if an adjacent building or water tank shades panels during peak hours. Always request a shade analysis using solar pathfinder software or string-level monitoring data.
Mistake 4 — Ignoring the fixed charges post-installation. Even with zero grid consumption, DGVCL bills a monthly fixed demand charge (typically ₹150–₹400/month). This will not go to zero. Factor it into your payback calculations.
Mistake 5 — Using a bank account that does not match the electricity account holder’s name. The PM Surya Ghar DBT transfer must go to a bank account in the same name as the DGVCL electricity account. Mismatches cause subsidy delays of weeks to months. Confirm name matching before submitting the application.
Mistake 6 — Not confirming DGVCL sanctioned load before purchase. If your sanctioned load is 3 kW and you plan a 5 kW installation, DGVCL will reject the application until you apply for load enhancement — a process that takes 2–4 weeks. Check your sanctioned load on your DGVCL bill before choosing system size.
Mistake 7 — Installing before feasibility approval. Installing the physical system before DGVCL feasibility approval is confirmed risks the entire subsidy. DGVCL can decline to process net metering for systems installed before feasibility clearance. Always wait for written feasibility confirmation.
Mistake 8 — Choosing a hybrid system when on-grid suffices. The battery in a hybrid system adds ₹1–₹1.5 lakh to system cost and carries a replacement cost every 8–12 years. For most Surat homes with reliable DGVCL supply, this cost is not justified by the backup benefit. Reserve hybrid for genuinely critical applications.
- You own the property with unobstructed flat roof access
- Monthly DGVCL bill is above ₹2,500 (mid or upper slab)
- System is sized close to your actual consumption
- You use an MNRE-empanelled, DGVCL-experienced installer
- Documents are in the electricity account holder's name
- You live in an apartment with a shared terrace (needs society approval)
- Significant shading from a neighbouring building between 9 AM and 3 PM
- Sanctioned load is below your planned system size
- Monthly DGVCL bill is below ₹1,000 — payback extends significantly

Frequently Asked Questions: Solar in Surat
What is the total cost of a 3 kW solar system in Surat in 2026?
A complete 3 kW on-grid rooftop solar system in Surat from an MNRE-empanelled installer costs ₹1,80,000–₹2,25,000 gross. After the PM Surya Ghar subsidy of ₹78,000, the net cost is ₹1,02,000–₹1,47,000. This covers panels, inverter, mounting structure, wiring, DGVCL application, and workmanship warranty. Costs vary based on panel tier, roof type, and installer.
How long does the complete solar installation process take in Surat?
From initial site visit to receiving the PM Surya Ghar subsidy in your bank account, the typical timeline for a Surat DGVCL installation is 45–75 days. DGVCL feasibility approval: 7–14 working days. Physical installation: 1–2 days. DGVCL post-installation inspection: 7–15 working days. Net meter installation: within 7 days of passing inspection. Subsidy DBT: within 30 days of commissioning certificate.
How much electricity will a 3 kW solar system generate in Surat each month?
A properly installed 3 kW system in Surat generates approximately 430–550 kWh per month as an annual average — around 5,200–6,600 kWh per year. Generation is highest October through May (520–600 kWh/month in peak months) and lower June through September due to monsoon cloud cover (300–380 kWh/month). Annual average at 5.6 kWh/m²/day with 0.80 PR: approximately 480 kWh/month.
Can apartment residents in Surat get solar under PM Surya Ghar?
Yes, but with additional steps. Apartment residents need a No Objection Certificate (NOC) from the housing society, agreement on which flats get roof space, and individual DGVCL consumer accounts for each applicant. Surat housing societies where the society itself has a common electricity connection need a different approach — contact DGVCL directly for commercial net metering options on common areas.
Which areas of Surat are best for solar installation?
All of Surat falls within DGVCL territory. From a solar resource standpoint, there is no meaningful difference between Adajan, Vesu, Althan, Katargam, Udhna, Varachha, Bhestan, or Dumas — all receive 5.5–6.2 peak sun hours daily. The relevant variables are roof orientation (south or west-facing preferred), shading from adjacent buildings, and sanctioned load. Flat-rooftop bungalow areas like Vesu and Adajan have the easiest installation logistics.
Is net metering available for commercial solar in Surat?
Yes. DGVCL offers net metering for commercial and industrial connections under the GERC commercial solar framework. The economics differ from residential: no PM Surya Ghar subsidy, but higher grid tariffs (₹7.50–₹9.50/kWh) mean faster payback. Businesses can also claim 80% accelerated depreciation in the first year. Commercial net metering applications go through the same DGVCL portal with additional documentation including CTO certificate and load sanction letter.
What happens if my solar generation exceeds my consumption in a month?
DGVCL credits the excess exported units to your account. These credits roll forward to subsequent months. At DGVCL’s annual reconciliation (typically March/April), any remaining export credits are settled at GERC’s approved feed-in tariff — approximately ₹2.25–₹2.75/kWh in 2026. This is significantly lower than the tariff you save by self-consuming (₹5.50–₹6.55/kWh), which is why system sizing to match consumption is important.
What maintenance does a Surat rooftop solar system need?
Surat’s coastal humidity and industrial air quality mean panels accumulate dust and salt deposits faster than inland Gujarat cities. Clean panels every 15–20 days during the dry season using plain water — a basic squeegee wash is sufficient. Inspect mounting structure fasteners annually for corrosion (galvanised steel should be fine for 10–15 years). Check inverter display weekly for any error codes. Schedule a professional inspection annually for warranty compliance. Panel performance should be within 97–98% of the previous year in Year 1–2, declining to 90% by Year 10 at the industry standard 0.5% annual degradation rate.
