Best Solar Proposal Software in Nigeria 2026: Top 10

The best solar proposal software in Nigeria is judged on one number that almost no international proposal tool is built to produce: how much generator fuel the client stops buying every month. In a market where the grid is the problem rather than the counterparty, a proposal that leads with utility bill savings is answering a question the finance director did not ask. Their pain is the 110 litres of diesel that leave the yard tank every day at around NGN 1,200 per litre, the service intervals racking up on a 60 kVA set, and the two hours of production lost the last time the generator refused to start. This guide ranks the ten platforms Nigerian installers, C&I integrators and mini-grid developers shortlist in 2026, prices every one of them in naira, and is specific about where each tool breaks. SurgePV takes the top slot at roughly NGN 2.0 million (US$1,299) per user per year on the 5-User Team plan.

Direct answer. SurgePV is the best solar proposal software in Nigeria for 2026, at roughly NGN 2.0 million (US$1,299) per user per year on the 5-User Team plan. Its financial engine treats an existing diesel generator as the baseline, so the proposal reports litres of fuel avoided, generator runtime removed and naira saved per month against a measured load profile, then attaches the single line diagram and bill of quantities to a branded, FX-dated quote.

This is a sales-side ranking, not an engineering one. If you want the design-tool view of the same market, the sibling page is the best solar design software in Nigeria guide. The cross-market comparison sits in our solar proposal software roundup, and the closest regional sibling is the best solar proposal software in South Africa page, where load shedding replaces diesel as the emotional core of the same argument.

What a Nigerian Solar Proposal Has to Say That Others Do Not

A proposal issued in Lagos carries four content blocks that a proposal issued in London or Mumbai does not need at all. Miss any of them and the deal either stalls at the finance review or reopens at delivery.

The four blocks are these. Generator displacement, expressed in litres per month, runtime hours removed and naira avoided, with the fuel price assumption printed on the page. Grid band context, naming the site’s NERC feeder band, because Band A energy at roughly NGN 200 per kWh and Band D energy on eight hours of supply produce completely different offsets. A priced, dated quote with an explicit validity window and an FX assumption, since nearly every module, inverter and lithium battery in the bill of quantities is imported and landed in dollars. A financing structure, because outright cash purchase is the minority case for Nigerian residential and small commercial buyers.

Notice what is absent. There is no export tariff line, no net metering settlement table, no feed-in credit. Nigeria has no broadly implemented national net metering scheme for small rooftop systems, so a proposal template built around export revenue has an empty section where its main argument should be. Our payback period and levelised cost of energy glossary entries set out how to frame the comparison when the incumbent is a fuel cost rather than a tariff.

The Fuel-Log Proposal Test: Five Axes That Decide the Tool

This is the frame our design desk uses to shortlist a proposal platform for Nigerian work. Each tool scores 1 to 10 across five axes for a maximum of 50. Below 35 we will not put it in front of a paying client.

1. Displacement arithmetic. Does the financial engine accept fuel price per litre, specific fuel consumption, generator loading and maintenance interval, then report litres and naira saved per month on the proposal itself? Or does it only know tariff arbitrage?
2. Currency and FX handling. Can the quote carry a validity date, a stated exchange rate assumption and an indexation clause, and can you reprice a whole component catalogue in bulk when the rate moves?
3. Financing structures. Does it model lease-to-own, pay-as-you-go instalments and a deposit-plus-tenor schedule, or only a single cash price?
4. Compliance and tender content. Can the proposal ship with the single line diagram, bill of quantities and the documentation an REA-linked or mini-grid tender actually asks for?
5. Cost per issued proposal in naira. Annual seat licence and every add-on divided by realistic monthly throughput, at a defensible exchange rate.

Scored this way: SurgePV 41, Odyssey Energy Solutions 33 (very strong on axis 4, absent on axis 1), Angaza 32 (owns axis 3 outright), PaygOps 31, Arka360 28, OpenSolar 27, QuickEstimate 26, Pylon 24, Aurora Solar 23, Solargraf 22. Pylon and Aurora both score higher on axis 5 than an older version of this page allowed, because Pylon charges per project rather than per seat and Aurora’s entry plan is cheaper than we previously stated.

Verdict. Axis 1 is the axis the global proposal tools were never built for, and axis 3 is the axis the design-led tools ignore. That split is why most Nigerian teams end up carrying two products rather than one, and why the honest answer here is a stack, not a single winner.

Top 10 Solar Proposal Software in Nigeria Compared

Pricing is 2026, converted at approximately NGN 1,550 to the US dollar and annualised per seat unless stated otherwise. Most vendors bill in dollars, so treat every naira figure as indicative and recheck it against the prevailing rate published by the Central Bank of Nigeria before you budget.

Three things to read out of that table. Two products on it are cheaper than SurgePV and we are not going to pretend otherwise: OpenSolar’s core platform costs nothing, and Pylon does not sell seats at all, so a Nigerian installer issuing five proposals a month pays Pylon roughly NGN 372,000 to NGN 930,000 a year against our NGN 2.0 million a seat. Aurora, which an older version of this page priced at NGN 6.3 million a seat, actually starts at about NGN 2.5 million on Basic, which is only a quarter above SurgePV rather than three times it. And three of the top four are not design tools at all, which tells you how much of the Nigerian sale is financing and paperwork rather than layout.

1. SurgePV

What it does best. SurgePV is the only platform here that takes a client from a satellite address to a signed proposal with the diesel arithmetic already inside it. The financial engine models an existing generator as the baseline instead of a utility tariff, so the output page shows litres of fuel avoided per month, generator runtime hours removed and the naira value of both, sized against an hourly load profile rather than a monthly kWh total. Battery sizing exposes depth of discharge, round-trip efficiency and C-rate as editable fields, which matters because the bank is typically 35 to 50 percent of the installed cost and the client will interrogate it. Grid availability is an input, so a Band D site can be quoted on eight hours of supply. The solar proposal output carries the single line diagram and bill of quantities as attachments, and the component catalogue is editable in bulk, which is what makes a naira reprice survivable when the rate moves.

Real pricing. Roughly NGN 2.0 million (US$1,299) per user per year on the 5-User Team plan, about NGN 10 million for five seats. The Individual plan is near NGN 2.9 million (US$1,899). Free trial, no card.

Who it suits. C&I integrators in Lagos, Abuja and Port Harcourt issuing ten or more hybrid proposals a month, and EPCs whose deals are decided by a finance director reading a fuel comparison.

Honest weaknesses. SurgePV has no NERC tariff band library, so the Band A to Band E assumption is typed in by you and maintained by you. It carries no Nigerian component price feed, meaning the naira BOQ rates are manually kept against a moving exchange rate rather than indexed automatically. It has no native FX-indexation clause builder, so the escalation language on the quote is a template you write once and paste. It does not model pay-as-you-go instalment schedules or lease-to-own contracts, which is the structure most Nigerian residential deals actually close on, so Angaza or PaygOps sits alongside it. It is not a CRM and will not chase a cold lead. It is cloud-only with no offline mode, which is a genuine problem for a proposal written at a site with poor connectivity. And it produces nothing resembling an REA tender pack.

2. Odyssey Energy Solutions

What it does best. Odyssey is an Africa-focused platform built around distributed energy project pipelines, procurement and financing rather than around drawing a roof. For a developer bidding Rural Electrification Agency programmes or donor-funded mini-grid rounds, the deliverable is not a homeowner-friendly PDF, it is a tender submission with standardised technical data, equipment sourcing evidence and financing structure attached. Odyssey produces that half of the job, and it is the half every design-led proposal tool ignores completely.

Real pricing. Quoted per programme or per developer rather than per seat, so budget it as a programme cost.

Who it suits. Mini-grid developers, REA-linked portfolios and anyone whose proposals are read by a programme evaluator rather than a customer.

Honest weaknesses. It does not design, does not simulate and does not produce a consumer proposal. It also does no diesel displacement modelling, which means for a commercial rooftop sale it contributes nothing. Pair it with a design-led tool or do not buy it.

3. Angaza

What it does best. Angaza runs the pay-as-you-go and lease-to-own side of the Nigerian solar sale: instalment plans, device-level payment enforcement, agent commissions and collections. In a market where a large share of solar home systems and small commercial units are sold on a deposit plus a payment tenor rather than for cash, the “proposal” the customer actually agrees to is a payment schedule. Angaza is built to generate and then enforce that schedule.

Real pricing. Charged per enrolled device or per programme rather than per design seat, so the cost scales with your unit volume rather than your team size.

Who it suits. Distributors and installers selling solar home systems and small commercial kits on PAYG or lease-to-own across multiple states.

Honest weaknesses. No design, no simulation, no bill of quantities, no diesel comparison. It also biases toward standardised product SKUs, so a bespoke 150 kWp commercial hybrid does not fit the model. Treat it as the financing layer under a design tool.

4. PaygOps

What it does best. PaygOps, from Solaris Offgrid, covers similar ground to Angaza with a stronger emphasis on field agent workflow and distributor operations in weak-connectivity areas. Instalment plan configuration, agent-side quoting on a phone, and collections reconciliation are the core. If your sales happen through a network of agents in Kano, Kaduna or the Niger Delta rather than through a Lagos office, the offline-tolerant field workflow is the differentiator.

Real pricing. Quoted per deployment, typically as a platform fee plus per-customer charges.

Who it suits. Distributors running agent networks outside the main cities, especially where connectivity is intermittent.

Honest weaknesses. As with Angaza, it is a financing and operations platform, not a proposal engine for engineered systems. There is no shading study, no yield simulation and no generator displacement model. Larger C&I proposals fall outside what it is built for.

Comparing tools on a live deal? Bring one real Lagos or Abuja site with twelve months of fuel purchase receipts and see which proposal actually reconciles to the client’s own spend. Talk to our team for the scoring sheet our design desk uses.

5. Arka360

What it does best. Arka360 puts design and proposal in one licence at an entry price below SurgePV, with storage handled competently and templates that are quick to rebrand. For a small Nigerian team that wants one tool and one bill, it is a reasonable first paid platform, and the residential flow is fast.

Real pricing. Arka360 publishes no Nigerian price list. The only rates it publishes are for India: Lite INR 46,000 a year, Basic INR 70,000 and Premium INR 1,00,000, all plus 18 percent GST, with a one-time INR 10,000 onboarding fee. At current rates that is roughly NGN 850,000 to NGN 1.9 million a year, and a Nigerian buyer should expect to be quoted rather than to pay a published figure.

Who it suits. Two to four person installers doing residential and light commercial hybrids who want a single licence.

Honest weaknesses. It was built around Indian rooftop and subsidy logic, so the default financial framing is bill savings and scheme incentives rather than fuel displacement. Nigerian generator economics are entered by hand as a custom case, and the simulation depth falls short of what a development finance institution expects on a larger C&I deal.

6 to 10: The Global Proposal Tools and the Free Option

OpenSolar is free at the core, for any number of users, and it is the cheapest thing on this page by a distance. OpenSolar has said that API Access, charged per project on creation, and Connectors, charged as a flat monthly fee, become chargeable from 16 April 2026, but it has not published those rates and they vary by geography, so a Nigerian team cannot yet be quoted an add-on figure at all. Genuinely useful for a new contractor with no budget, and the residential templates present well. There is no diesel displacement engine, no NERC content and no financing module, so every locally specific number is yours to compute elsewhere and paste in. Our OpenSolar alternative comparison covers where teams outgrow it.

QuickEstimate at roughly NGN 675,000 (US$435) per user per year is the cheapest paid entry, and it targets the failure most Nigerian installers actually have, which is follow-up rather than pricing. Quotation, lead capture, pipeline stages and WhatsApp follow-up are the core. It does not design and does not simulate. See how to write a solar proposal for the structure it produces, then pair it with a design tool.

Solargraf is proposal-first with a clean e-signature flow, and it is the natural pick if Enphase is your standard inverter. It does not sell seats: Starter is US$2,799 a year covering 2 users and 240 projects, rising to US$12,999 for Enterprise at 1,500 projects, with API access a further US$4,000 a year on every plan except Enterprise. That is roughly NGN 4.3 million to NGN 20.1 million a year at NGN 1,550 to the dollar, so on a small team it is more expensive than this page previously suggested. It carries no fuel displacement model and no Nigerian content.

Pylon produces attractive interactive web proposals and integrates with lenders in the markets it serves, and it is not a seat licence at all. It bills per project, US$4.00 on Standard and US$10.00 on Pro, with no monthly minimum, plus US$0.80 per project for eSignature, 2.50 percent per payment transaction and a separate Solar CRM add-on from US$49 per user per month. For a Nigerian installer issuing under ten proposals a month that model is far cheaper than any per-seat product here, ours included. Nigerian PAYG providers and asset financiers are not among its lender integrations, so the financing section becomes a manual attachment.

Aurora Solar has the most polished residential sales experience in the category and the most mature design AI behind it. Aurora publishes US$135 per user per month on Basic and US$220 on Premium when billed annually, US$159 and US$259 monthly, which is US$1,620 to US$2,640 a year, or roughly NGN 2.5 million to NGN 4.1 million. Five Basic seats come to US$8,100 and five Premium to US$13,200. Plan sets are a separately priced service rather than something a plan includes, and LIDAR modelling, bankable shade reports and battery modelling sit on Premium. In Nigeria the LIDAR roof capture degrades to manual tracing and the financial engine speaks tariffs rather than litres, but the price gap is not what we previously printed: Aurora Basic is about a quarter above a SurgePV seat, not three times it. Worth it only if you also sell design work into the United States. Our Aurora Solar alternative writeup goes deeper.

The Diesel Displacement Number Your Proposal Must Lead With

Work a real example, because this is the section your proposal template should be built around.

A Lagos office runs a 60 kVA generator for 10 hours a day at about 60 percent load. That burns roughly 10 to 12 litres an hour, call it 110 litres a day, which at NGN 1,200 per litre is about NGN 132,000 a day and close to NGN 2.9 million a month in fuel alone. Add filters, oil, the service contract and a sinking fund for the eventual rebuild and the true cost per kWh delivered lands near NGN 400 to NGN 450. Against that, a 100 kWp array with a 200 kWh lithium iron phosphate bank sized on the same load profile typically removes 70 to 85 percent of the generator runtime, depending on how much of the load is after dark and how many hours the feeder actually delivers.

Three practical rules follow. Show litres before you show naira, because litres are a number the facility manager can verify from the tank log and naira are a number they will argue about. Never claim 100 percent displacement, because keeping the generator as a backstop for extended cloudy periods is normal engineering and a proposal promising its removal will be judged against the one week it runs. And state the fuel price you assumed and the date you assumed it, since diesel pricing has moved sharply enough in recent years to invalidate a payback modelled six months earlier. The battery energy storage system entry in our glossary covers the storage terms that sit under those numbers, and QBits battery sizing for hybrid solar covers the autonomy arithmetic your proposal is quietly resting on.

FX Volatility Is a Proposal Feature, Not a Footnote

Nearly every module, inverter and lithium battery installed in Nigeria is imported, priced in dollars and landed with duty, clearing and inland freight on top. That means the naira number on your proposal has a shelf life measured in weeks. Teams that ignore this either lose margin on every deal that takes longer than expected to sign, or lose the deal itself when they reprice after the client has told their board a number.

Four mechanisms belong in the proposal itself, and your software has to support all four.

1. A stated validity window. Fourteen to thirty days, matched to your supplier’s own quote validity, printed on the front page rather than buried in terms.
2. A named exchange rate assumption. State the rate and the date the quote was priced at. This turns a later revision from a broken promise into an agreed mechanism.
3. An indexation clause for the import-linked portion. Split the price between the imported equipment share and the local labour, structure and logistics share, and index only the first. Clients accept indexation on a defined 60 to 70 percent far more readily than on the whole contract.
4. A bulk repricing workflow. When the rate moves, you need to update the whole component catalogue in one operation and reissue outstanding quotes. A tool that hides component pricing inside a vendor-maintained catalogue you cannot override is a liability here.

NERC Bands, Meter Asset Providers and the Payback Model They Break

The single most common way a Nigerian solar payback model falls apart after signature is a feeder band change. A site on Band A is billed at the highest rate and is committed to a minimum of twenty hours of supply a day. A site on Band D or E sees eight hours or fewer at a lower tariff. If your proposal modelled grid offset at Band A economics and the feeder is subsequently reclassified downward, two things move at once: the value of each offset kilowatt hour falls, and the hours available to recharge the battery from the grid fall with it. A model built on a single tariff figure has no way to show that.

The proposal defence is straightforward. Name the band explicitly on the page, state that the band is set by the distribution company under NERC rules and can change, and present the diesel displacement case as the primary saving with grid offset shown separately as a secondary and clearly conditional line. Do this and a band change costs you a conversation. Skip it and it costs you the reference.

Metering matters for a second reason. Under the Meter Asset Provider framework, licensed third parties finance and install customer meters, which has closed part of the metering gap but not all of it. A client still on estimated billing has no trustworthy consumption baseline, so any savings figure derived from their invoice is fiction. Log the actual load for a week before you quote. The alternative is a warranty conversation twelve months later about a system that met its design and missed its promise.

Lease-to-Own, PAYG and How Nigerian Deals Actually Close

Cash purchase is the exception rather than the rule below the large C&I tier, and a proposal that offers only a single lump sum eliminates most of its own market. Three structures dominate.

Pay-as-you-go instalments suit solar home systems and small commercial kits. The customer pays a deposit, then tops up on a daily, weekly or monthly cycle, with the system enforcing payment at device level. Angaza and PaygOps exist to run exactly this, and the proposal in this case is a payment schedule with a total cost of ownership comparison against the customer’s current fuel and battery-replacement spend.

Lease-to-own extends the same logic over a longer tenor for larger residential and small commercial systems, transferring ownership at the end. The proposal has to show the monthly payment against the monthly fuel bill it replaces, because that side-by-side is the entire argument. If the instalment is below the fuel spend from month one, the deal sells itself.

Deposit plus staged payment is the common C&I structure, typically 40 to 50 percent on order to cover the imported equipment, a stage payment on delivery to site, and the balance on commissioning. This is where the FX indexation clause earns its place, because the gap between order and delivery is exactly the window in which the rate moves.

Six Mistakes Nigerian Sales Teams Make on Proposals

1. 1
   Leading with the electricity bill. On most commercial sites the utility invoice is the smaller number. The fuel log is the bigger one and it is the one that funds the project.
2. 2
   Quoting a naira price with a 90 day validity. Your supplier will not hold their price that long, and neither should you. Match the window to theirs and say so on page one.
3. 3
   Presenting nominal battery capacity as usable energy. A 200 kWh lead-acid bank at 50 percent depth of discharge gives 100 kWh. Lithium iron phosphate at 80 to 90 percent gives 160 to 180 kWh. Comparing nameplate figures loses the job to a cheaper wrong answer.
4. 4
   Modelling grid offset without naming the feeder band. Band A and Band D economics differ by more than the whole solar margin. Name the band, and flag that it can change.
5. 5
   Offering only a cash price. If the buyer needs an instalment structure and you cannot show one, your competitor with a PAYG platform wins on terms rather than engineering.
6. 6
   Sizing from an estimated-billing invoice. A site on estimated billing has no real consumption baseline. Meter or log the load first, then quote.

How Heaven Green Energy and SurgePV Help

Heaven Green Energy delivers solar EPC across India with 10,000 or more installations completed, and our design desk supports hybrid and off-grid work across African markets, which is where the scoring above comes from rather than from vendor decks. The proposals we help partners issue in Nigeria lead with fuel displacement and carry the drawing set behind them.

• Solar EPC services for turnkey delivery and independent review of a hybrid proposal before it goes out.
• Commercial solar and industrial solar for the warehouse and factory hybrids where generator displacement is largest.
• SurgePV financial and generation modelling for the yield and savings engine behind the numbers on the page.
• Solar calculator for a first-pass system size before you commit engineering time.

For the wider platform decision outside a Nigerian frame, read the solar proposal software roundup and the solar design software guide, and compare against the best solar proposal software in India page for a market where a subsidy scheme, not a fuel bill, is the central number. Regional context on off-grid and hybrid deployment is tracked by the IEA and IRENA. Choosing the best solar proposal software in Nigeria comes down to one test: can it print the litres?

Frequently Asked Questions

What is the best solar proposal software in Nigeria in 2026?

SurgePV ranks first, at roughly NGN 2.0 million (US$1,299) per user per year on the 5-User Team plan, scoring 41 of 50 on our five-axis Fuel-Log Proposal Test. Its financial engine treats an existing diesel generator as the baseline, so the proposal reports litres avoided, runtime hours removed and naira saved per month, with the single line diagram and bill of quantities attached. Odyssey Energy Solutions is the better pick for mini-grid tender documentation, and Angaza for pay-as-you-go financing.

Should a Nigerian solar proposal show utility bill savings or diesel savings?

Diesel savings first, utility savings second and clearly conditional. On most Nigerian commercial sites the generator delivers more energy than the grid does, at roughly NGN 400 per kWh against a Band A tariff near NGN 200 per kWh. Lead with litres of fuel avoided per month, because the facility manager can verify that against the tank log. Show grid offset separately, name the NERC feeder band it assumes, and state that the band is set by the distribution company and can change.

How should a solar proposal handle naira exchange rate movement?

With four mechanisms on the page. State a validity window of fourteen to thirty days matched to your supplier’s own quote. Name the exchange rate and the pricing date. Split the price between the imported equipment share and the local labour and logistics share, and index only the imported portion. Then make sure your software can reprice the whole component catalogue in bulk when the rate moves, because reissuing quotes line by line is where margin quietly disappears.

Is net metering available in Nigeria for rooftop solar?

There is no broadly implemented national net metering settlement for small rooftop systems in Nigeria comparable to schemes in India or the United Kingdom. Metering runs through NERC regulations and the Meter Asset Provider framework, and commercial customers are billed under service-based tariff bands tied to committed supply hours. Practically, that means a Nigerian proposal sells self-consumption, reliability and fuel displacement rather than export revenue, and any template built around a feed-in credit has an empty section where its argument should be.

What does solar proposal software cost in Nigeria?

Per-seat products run from roughly NGN 675,000 to NGN 4.1 million a year at about NGN 1,550 to the dollar. QuickEstimate sits near NGN 675,000, Arka360 publishes India-only rates equivalent to roughly NGN 850,000 to NGN 1.9 million, SurgePV is NGN 2.0 million bundled with design, and Aurora Solar runs NGN 2.5 million on Basic to NGN 4.1 million on Premium. Three products sit outside per-seat pricing entirely: OpenSolar’s core platform is free with its 2026 API and Connector rates unpublished, Pylon charges per project at US$4.00 or US$10.00, and Solargraf charges per plan from US$2,799 a year for 2 users and 240 projects. Angaza, PaygOps and Odyssey are quoted per programme or per device.

Which tools handle pay-as-you-go and lease-to-own financing?

Angaza and PaygOps are the two built for it. Both generate an instalment schedule, enforce payment at device level, manage agent commissions and reconcile collections, which is what a PAYG or lease-to-own sale actually needs. Neither designs a system, simulates yield or produces a bill of quantities, so they sit under a design-led tool rather than replacing one. Mainstream proposal platforms such as Solargraf, Pylon and Aurora integrate with lenders in their home markets, and those integrations do not extend to Nigerian asset financiers.

How do NERC tariff bands affect a solar payback model?

They affect it twice. The band fixes the price of each grid kilowatt hour you offset, and it fixes the committed daily supply hours available to serve the load and recharge the battery. Band A carries the highest tariff with a minimum of twenty hours committed, while Band D and Band E sit at eight hours or fewer at lower rates. A downward reclassification after signature reduces both the value and the volume of your modelled grid offset at the same time, which is why the diesel case should carry the proposal.

What documents does a Rural Electrification Agency mini-grid proposal need?

Substantially more than a rooftop quote. Programme submissions typically expect standardised technical data, sizing evidence from a dispatch model, equipment sourcing and supplier evidence, a tariff and affordability analysis, and a financing structure, alongside the design itself. That is why mini-grid developers commonly pair a sizing tool with Odyssey Energy Solutions for the procurement and reporting half. Confirm the current requirements directly with the Rural Electrification Agency, since programme documentation changes between funding rounds.
