Terrace solar for housing societies in Rajkot.
Your Rajkot housing association pays PGVCL every month for the lifts, the water pumps and the lights in every corridor. A plant on the terrace, wired to that shared connection, takes units off the bill all owners fund through maintenance. We read the common-meter bill, survey the roof with your committee and file the paperwork with your PGVCL sub-division.

The short answer
Yes, a Rajkot housing society can install rooftop solar on its terrace and connect it to the common connection that PGVCL bills to the association. Each kilowatt yields 4 to 4.5 units a day. MNRE's PM Surya Ghar operational guidelines (June 2024) give ₹18,000 per kW for a plant on a connection dedicated to common facilities, EV charging included. The cap is 3 kW per house and 500 kW overall. DCR modules are mandatory.

What a Rajkot society plant actually powers
The plant serves the association's shared account and nothing else. Each flat keeps its own PGVCL meter and pays its own bill. So the first job is a list of every load on the common connection and the hours it runs.
Your bill tells us which office handles the file. PGVCL's disaster management plan for 2025 lists the Rajkot City circle in three divisions. Their sub-divisions carry familiar names: Kalawad Road, Mavdi Road, Nana Mava, Mota Mava, Raiya Road, Madhapar, Kothariya Road and Morbi Road among them. The sub-division printed on your common-meter bill is where the net-metering application goes, so we read it before anything else.
Societies on the edge of the city may sit in another circle. The same plan places Shapar-Veraval, Lodhika, Metoda, Kuvadva and Paddhari under the Rajkot Rural division. A scheme built on the fringe can therefore be billed by a rural sub-division. The rules are the same, but the office and the inspection team differ.
Load profiles vary more than buyers expect. A ground-plus-four block with one pump and stair lights draws little. A tower with several lifts, a fire pump, basement parking lights and a clubhouse can run a common bill bigger than any flat. We size the plant against twelve months of that account, then check what the terrace can hold.
Lifts and their controllers
Lift motors pull short, heavy bursts of current, mostly in the morning and evening rush. Controllers and cabin fans draw a small load all day. In taller Rajkot buildings with two cars per wing, lifts tend to lead the common account. The plant offsets their units on the monthly bill rather than feeding them directly.
Water pumping
Most societies push water from an underground sump to overhead tanks, and some add a borewell or booster pump. Pumping is the one load a committee can easily reschedule. A timer that runs the main pump between ten and three uses solar output on site, which beats exporting it and drawing back later.
Corridor, parking and gate lighting
Lighting runs from dusk to dawn, so it never overlaps generation. Those units are covered by credits from daytime export. Switching old fittings to LED before sizing cuts the night load, which shrinks the plant the society needs and the cash the general body must approve.
EV chargers and shared amenities
Newer schemes add a gym, a hall and shared EV chargers to the common account. MNRE's PM Surya Ghar guidelines name EV charging among the common facilities a society plant may serve. List any chargers you plan to install, so the plant and the connection are sized once.
Judge the plant in units, not rupees
Count the units a plant removes from the common account each month. Your treasurer converts those to rupees using the category and slabs on your own PGVCL bill, so this page states no tariff and no saving.
Output first. On a clear Saurashtra terrace each kilowatt averages 4 to 4.5 units a day. A 10 kW plant gives about 1,200 to 1,350 units a month. A 25 kW plant gives about 36,500 to 41,000 units a year, and a 100 kW plant about 1.46 to 1.64 lakh units. Lay those figures beside a year of common-meter bills and the committee sees what share of the shared load the roof can carry.
Daytime use matters more than size. Units the building consumes while the sun is up never reach the meter as a draw. Surplus units go to PGVCL and are set against night consumption under the GERC net-metering framework. A society that moves its pump runs and any EV charging into daylight keeps more of its own output. PGVCL also tests the plant against the sanctioned load of the common connection and the feeding transformer. A building that has added lifts or chargers since handover may need a load revision first.
Tax and GST. Since 22 Sep 2025, GST is 5% on solar equipment and 18% on the service share, taken as 30% of a supply-and-install contract, which blends to about 8.9%. A housing society usually cannot recover it, so budget the price inclusive of GST. The 40% accelerated depreciation in Appendix I of the Income Tax Rules suits taxpaying businesses, and rarely helps a society; ask your auditor. At the 25 kW size the market band of ₹10.75 lakh to ₹13.50 lakh works out to about ₹43,000 to ₹54,000 per kW. Larger plants are priced after a load study.
| Plant size | Units a year |
|---|---|
| 25 kW | 36,500 – 41,063 |
| 50 kW | 73,000 – 82,125 |
| 100 kW | 1,46,000 – 1,64,250 |
| 250 kW | 3,65,000 – 4,10,625 |
| 500 kW | 7,30,000 – 8,21,250 |
Indicative installed cost at 25 kW: ₹10.75–13.50 lakh (market range, not a quotation). Larger plants are priced after a load study of your bills and roof.

Roof, structure and wiring on a Rajkot apartment block
A society terrace is shared ground. Tanks, lift rooms and residents all need it, so the survey settles usable area, how the structure holds down and how cables reach the meter room.
Usable, shade-free area
We plot the shadows of overhead tanks, the lift machine room, the stair head and the parapet through the year, because the low winter sun stretches each one. The area left is what we design on. Where tanks crowd the roof, a raised structure clears them and keeps the slab walkable for cleaning and maintenance.
Wind, dust and the slab
Saurashtra's dry months coat modules in fine dust, so we plan a safe walkway and a tap point for washing. Pre-monsoon squalls test the structure, which is why we use hot-dip galvanised steel and check anchors against wind load. Ballasted or chemically anchored bases avoid cutting the waterproofing; any unavoidable hole is sealed.
Cable route and PGVCL inspection
The cable usually drops several floors through a shaft to the common-meter room. We size conductors for that run and fit an isolator, surge protection and earthing that PGVCL inspectors can check in one visit. The inverter goes where it is shaded and ventilated, never on a hot, exposed wall beside the lift room.
Approvals: who does what.
PGVCL acts on a society application only when the association's own papers are complete. We draft them with the committee, then file and follow the case through your sub-division.
General body resolution and bill check
The committee passes a resolution approving the plant and naming who signs. We check that the common-meter bill is in the society's name and confirm the current document list with your PGVCL sub-division, since requirements can change between seasons.
UsApplication in the society's name
We file with the sub-division printed on your bill, attaching the resolution, the latest bill, the plant rating, a single-line diagram and equipment data sheets. For a PM Surya Ghar claim, the society also registers on the national portal.
UsFeasibility, then installation
PGVCL checks the proposed capacity against the common connection's sanctioned load and the local transformer. We start work only after feasibility clears. Inspectors then examine earthing, protection and isolation on the terrace and at the meter room.
Us, then PGVCLNet meter and commissioning
PGVCL replaces the common meter with a bidirectional meter and records commissioning. Export credits on the society account start from that date. Any central support claim then proceeds against the commissioned plant on the national portal.
PGVCLThree ways to fund the plant.
A society needs a funding route the general body can vote on and the minutes can record. Three routes cover most Rajkot committees; your bylaws decide which ones apply.
PM Surya Ghar support for the society
MNRE's PM Surya Ghar operational guidelines (June 2024) give ₹18,000 per kW to a GHS or RWA for a plant on a connection used only for common facilities. Support stops at 3 kW per house and 500 kW. The cap counts plants residents already own, and DCR modules are mandatory.
Sinking fund or a one-time levy
Many societies pay from the sinking or repair fund, or raise a levy per flat that the general body approves. Paying outright keeps the plant free of interest. We give the committee a written bill of materials and a fixed scope, so owners can see what each instalment buys.
Loan or EMI through a finance partner
Where the fund cannot cover the plant, a loan through our finance partner spreads the cost into instalments. Eligibility depends on the society's registration, accounts and bank, and the lender decides. Ask early, because lenders often want the resolution and audited statements before they sanction anything.
How the project runs.
Five stages run from the first bill review to the bidirectional meter. Timings depend on PGVCL and on how quickly the committee meets.
Where we work from
Heaven Green Energy's only office is at Mota Varachha, Surat. We do not have a branch in Rajkot. Societies here are served through our channel partner network and field engineering team, who survey terraces, supervise installation and attend PGVCL inspections across Saurashtra. We say this at the first meeting, before the committee signs anything.
Bill and load review · 1 to 2 days
We read twelve months of common-meter bills, the sanctioned load and the sub-division. We list every shared load and its running hours, then draft a size range for the committee.
Terrace survey · 1 day on site
An engineer measures the roof, maps shade from tanks and lift rooms, checks the slab and plans the cable route. Committee members are welcome to walk the roof with us.
Proposal and resolution · Set by your committee
You receive a written proposal with plant size, expected units, bill of materials and the support calculation. The general body votes, and the resolution goes into the application file.
Filing and feasibility · Depends on PGVCL
We file with your sub-division and answer any query from PGVCL. Installation waits until feasibility is released, so nothing is built that the licensee might later refuse.
Install, inspect, commission · Plant size decides
We install the structure, modules and inverter, then attend the PGVCL inspection. The bidirectional meter goes in, commissioning is recorded, and we hand over drawings and warranty papers.
What businesses say after a year.
These reviews come from Heaven Green home customers, shown with the city where each system went in. They are home installations, not society projects, and each keeps the city where it was actually installed.
Compared 5 vendors, Heaven Green's quote was the most transparent. No hidden fees. Adani panels installed on schedule, structure is solid.
Residential · Rajkot · 4 kW
Got the full ₹78,000 PM Suryaghar subsidy credited within 30 days of commissioning. Not one extra trip needed, they did all the follow-up.
Residential · Vadodara · 6 kW
Zero advance, just like they promised. EMI through their finance partner, installation done before the first payment was due. Bills practically gone.
Residential · Mehsana · 5 kW
Six things to check with any vendor.
- The plant connects to the society's common connection only; flats keep their own PGVCL meters and bills.
- Your bill names the PGVCL sub-division, such as Kalawad Road or Mavdi Road, that will process the file.
- Each kilowatt gives 4 to 4.5 units a day; a 100 kW plant makes about 1.46 to 1.64 lakh units a year.
- PM Surya Ghar gives a GHS or RWA ₹18,000 per kW for common facilities, capped at 3 kW per house and 500 kW.
- That cap includes plants residents already installed, and only DCR modules qualify for support.
- Move pumping and EV charging into daylight hours, so the building uses more of its own output.
