What to Include in a Solar Installation Quotation in Nigeria

A clear quotation wins jobs. A vague one starts arguments, especially when equipment prices move with the exchange rate. Here is what a professional solar installation quotation in Nigeria should include, section by section.

1. Your business details

Your company name, logo, address, phone, email and CAC registration number if you have one. Give the quotation a reference number and a date, so you and the client can always point to the same version.

2. Client and site details

The client’s name, phone number and the site address, including the state. Add a line about the site, such as “Rooftop installation, three-bedroom bungalow, Uyo, Akwa Ibom”.

3. What the system will power

Attach or summarise the load list, so the client can see exactly which appliances the system is designed for and for how many hours. This protects you later. If the client adds a second AC and the batteries run flat, the quote shows what was agreed. Our load audit checklist explains how to build one.

4. System design summary

• Inverter size in kVA, and type, such as pure sine wave hybrid
• Battery bank: type (lithium or lead-acid), voltage and total capacity in kWh or Ah
• Solar panels: number, wattage and total array size
• Charge controller, if separate
• Expected backup time for the agreed loads

5. Bill of materials

List every item with its brand or model, quantity, unit price in naira and line total. Do not leave out the smaller items, because they add up:

• Solar panels, inverter, batteries and charge controller
• Panel mounting rails, clamps and roof hooks
• DC and AC cables, sized for the current and distance
• DC and AC breakers, isolators and surge protection
• Combiner box, battery rack and cable lugs
• Earthing rod and cable

6. Labour and other costs

Show installation labour, transport and logistics, and any scaffolding or roof work as separate lines. Clients trust a quote more when they can see where the money goes.

7. Discount, VAT and total

Show the subtotal, any discount, VAT and the total payable. Nigeria’s VAT rate has been 7.5% since 2020, but check the current rate and whether your business must charge it.

8. Validity period

Equipment prices in Nigeria can change quickly with the exchange rate. State how long the quote is valid, for example 7 or 14 days, and that prices may change after that.

9. Payment terms

Say when and how payment is due, and which bank account to pay into. Be specific about whether you need full payment before installation.

10. Warranty, timeline and exclusions

• Warranty on each major item, as given by the manufacturer, plus your own workmanship warranty
• How long installation will take after payment
• What is not included, such as rewiring the house, civil works or extra appliances
