The verdict in three sentences
A manufacturer or hotel owner in Bamako facing power cuts and a rising EDM bill wants a number before meeting a salesperson: how much they will save and how many years until payback. A C&I (commercial and industrial) solar installer website at 3,000,000 to 6,500,000 FCFA (about 4,600 to 9,900 EUR), equipped with a savings calculator, turns that need into qualified requests with the monthly bill, contracted capacity and operating hours. For 100 kWp plants sold at 60 to 80 million FCFA with a 3 to 5 year payback, one signed contract pays for the website several times over.
What a B2B solar integrator website must include
The decision maker (plant director, hotel CFO, flour mill or clinic manager) needs technical and financial proof. The website must show real plants, production figures and a journey that collects the right data from first contact.
| Module | Content | 2026 budget | Commercial impact |
|---|---|---|---|
| Sector pages | Industry, hospitality, healthcare, agro-processing, telecoms | 600,000 to 1,200,000 FCFA | Speaks each buyer's language |
| Plant references | Capacity, annual output, savings, drone photos | 400,000 to 900,000 FCFA | Proof of capability |
| Savings calculator | EDM bill, capacity, hours, storage, PDF output | 1,200,000 to 2,500,000 FCFA | Qualifies the lead and sizes the project |
| Financing pages | Cash purchase, bank loan, leasing, third-party investment | 300,000 to 600,000 FCFA | Removes the price objection |
| Maintenance and monitoring | O&M contracts, remote monitoring | 200,000 to 500,000 FCFA | Recurring revenue |
| CRM and WhatsApp | Lead sent to sales with the simulation | 300,000 to 800,000 FCFA | Callback within 24 h |
| Total | 3,000,000 FCFA | 6,500,000 FCFA | 7-week delivery |
The calculator relies on transparent assumptions: output of 1,550 to 1,750 kWh per kWp per year in Bamako, an EDM medium-voltage tariff of 110 to 140 FCFA per kWh depending on time band, and self-consumption of 70 to 95% depending on the load profile. It shows a range, never a promise, and offers a site survey.
Calculator or simple form: the difference in leads
A "Contact us" form attracts requests from households wanting 2 panels, resellers and the merely curious. The calculator filters naturally: a visitor who enters a 4,500,000 FCFA monthly bill is a genuine industrial prospect.
| 12-month indicator | Simple contact form | Savings calculator |
|---|---|---|
| Requests received | 180 | 140 |
| Share of qualified B2B leads (bill above 1,000,000 FCFA a month) | 15% | 55% |
| Qualified leads | 27 | 77 |
| Site surveys carried out | 12 | 34 |
| Plants signed | 2 | 6 |
| Sales time lost on unqualified leads | 150 h | 40 h |
| Value of signed contracts (70M FCFA plants) | 140,000,000 FCFA | 420,000,000 FCFA |
These are 2026 estimates for a mid-sized integrator in Bamako spending 2,000,000 FCFA a month on online promotion. Above all, they show that the calculator saves time for sales engineers, the most expensive resource.
Mini case study
Mamadou, sales director of a solar integrator in Bamako, sells mostly through his personal network, 4 plants a year. He invests 5,200,000 FCFA in a website with a calculator and sector pages, plus 1,500,000 FCFA a month in campaigns.
A typical client, an 80-room hotel, pays EDM 6,000,000 FCFA a month. A 100 kWp plant at 70,000,000 FCFA produces about 165,000 kWh a year, roughly 20,000,000 FCFA of savings at 120 FCFA per kWh: payback in 3.5 years. Over the year, the website brings in 3 additional plants. At an 18% margin, that is 3 × 70,000,000 × 0.18 = 37,800,000 FCFA of margin, for a total cost of 5,200,000 + 18,000,000 = 23,200,000 FCFA.

FAQ
How much does a B2B solar installer website cost in Bamako in 2026?
Budget 3,000,000 FCFA for a site with sector pages and a simple calculator, up to 6,500,000 FCFA with a detailed calculator, PDF export, CRM and illustrated references. Maintenance costs 75,000 to 200,000 FCFA a month.
Should the calculator include battery storage?
Yes for sites that run at night or suffer long outages. Batteries often add 30 to 50% to the plant price, and the calculator should show the effect on payback.
Which EDM tariff should the calculations use?
The actual tariff the client enters from their bill, with a default of 110 to 140 FCFA per kWh at medium voltage. The calculator must state clearly that the exact value will be confirmed during the site survey.
Should we display the price of a plant?
An indicative range helps: 600,000 to 800,000 FCFA per installed kWp without storage in 2026. It avoids meetings with prospects whose budget is too far off.
Can the website target other WAEMU countries?
Yes, country pages (Senegal, Burkina Faso, Côte d'Ivoire) with Senelec, SONABEL or CIE tariffs add 400,000 to 900,000 FCFA. They open up regional tenders.
