How do you choose a solar quote?
Choosing a solar quote is less about finding the lowest price and more about finding the right fit for your home. A solar system is a 15 to 20-year investment, so what matters is what each quote gives you for the money and how well it matches your energy needs. The best quote covers your actual usage, uses quality components, and comes from a trusted installer committed to long-term service.
Learn how to compare different solar quotes so you can easily find the system and price that fit your specific energy goals. For a full breakdown of what a system should cost, see our guide to solar prices in Nigeria.
Why the "best" price depends on what your home actually needs
There is no single 'right' price for solar, because the best system for a small flat is nothing like the best system for a large home running several air conditioners. What you pay mostly reflects how much power you use, how many hours of backup you want, and the size of system needed to deliver it. A smaller, simpler setup can cost far less and still be top quality.
That means a lower quote is not a worse quote. Once you are comparing quality installers, the decision is about fit rather than a quality scale. The right size gives you enough capacity to cover your usage without paying for headroom you will never touch. Match the system to your needs first, and the right price follows.
What to check in every solar quote
Before you compare prices, make sure each quote spells out these details. If a quote is vague on any of them, ask for specifics.
| What to check | Why it matters |
|---|---|
| System capacity (kW) | Undersize it and you run out of power; oversize it and you pay for capacity you never use. |
| Battery type and usable capacity (kWh) | This sets how many hours you run after dark, and lithium lasts far longer than tubular or lead-acid. |
| Inverter type and rating | If the rating is below your peak load, the system trips when too much runs at once. |
| Panel wattage and brand | Better panels hold their output for longer and fit more power onto limited roof space. |
| Warranties | A warranty is only as good as the company behind it, so check who actually pays if a part fails. |
| Installation and aftercare | A good system fitted badly still fails, and vague scope is where hidden costs hide. |
| Payment options | The lowest sticker price can end up costing more once financing or subscription terms are included. |
Why a higher quote can be the better deal
A side-by-side comparison is where the real differences surface. Two quotes for the same home can be more than a million naira apart, and that gap usually reflects the size and specification of the system rather than the quality of the installer. What decides value is what each quote actually includes:
| Quote A | Quote B | |
|---|---|---|
| Price | ₦4.2M | ₦5.4M |
| Battery | 5 kWh tubular | 10 kWh lithium |
| Inverter | 3.5 kW standard | 5 kW hybrid |
| Warranty | 1 year | 5 years |
| Battery lifespan | 3 to 5 years | 10+ years |
While Quote A offers a lower entry price, Quote B includes a larger battery capacity and longer cover, which drops your overall cost per unit over time. Weighing upfront savings against long-term performance helps you decide which type of value fits your budget best.
What you should expect from a high-quality solar quote
Beyond the numbers, the way a quote is put together tells you a lot about the installer. The signs of a good one are easy to spot once you know what to look for:
- An itemised breakdown lets you see exactly what you are paying for and compare quotes fairly.
- A site assessment shows the installer has checked your loads and roof before pricing the system.
- Sensible payment terms mean you are not asked for the full amount before the system is installed and working.
- Clear, written warranties spell out the cover on each part and who honours it.
When a quote ticks these boxes, you can compare on price and fit with confidence.
Questions to ask every installer
Before you commit, put the same questions to each installer so you can compare their answers side by side:
- What size system are you recommending, and how did you work it out?
- What battery and inverter are you using, and what are their warranties?
- What is included in the installation price, and what costs extra?
- What happens if the system underperforms after installation?
- What payment options do you offer, and what is the total cost of each?
How Senergy makes choosing easier
Comparing quotes properly takes time, and most people are doing it for the first time. Senergy takes the guesswork out of it. Every installer on the platform is vetted for technical capacity and track record, and their quotes are normalised so you can compare them like-for-like in one view. Your payment is held until you confirm the system is installed and working, so you are never paying for a promise.
Try the energy price calculator for an instant estimate, or compare quotes to see vetted options for your home side by side.
