The verdict in three sentences
A solar installer targeting commercial and industrial (C&I) clients in Singapore is not selling panels, it is selling a lower electricity bill and a carbon number the client can report, and the website must prove both. A complete B2B site with a savings calculator and kWp case studies costs around SGD 25,000 to 55,000 (USD 19,000 to 41,000) in 2026, delivered in 8 to 10 weeks. One 500 kWp rooftop contract pays for that budget several times over.
What a facilities or sustainability director looks for
In Singapore, solar buyers are facilities managers, CFOs and sustainability leads at manufacturers, logistics hubs, data centres and JTC industrial estates. Electricity tariffs for non-domestic users remain high by regional standards, and many listed groups must report Scope 2 emissions. Most deals go through structured procurement: an RFP, a shortlist of three to five installers and a comparison of solar leasing (PPA) against capital purchase.
The website therefore has to win the shortlist: project references with kWp installed, annual yield, savings and CO2 avoided, rooftop and structural engineering credentials, licensing, warranty terms and a clear page on PPA and leasing models, which finance teams want before they invite you to tender.
| Client profile | Typical consumption | Monthly power bill (2026 ballpark) | Target system size |
|---|---|---|---|
| Food processing plant | 250,000 kWh/month | SGD 70,000 to 80,000 | 400 to 700 kWp |
| Logistics warehouse | 120,000 kWh/month | SGD 34,000 to 40,000 | 300 to 500 kWp |
| Private hospital wing | 200,000 kWh/month | SGD 56,000 to 64,000 | 250 to 400 kWp |
| Light manufacturing unit | 80,000 kWh/month | SGD 22,000 to 27,000 | 200 to 350 kWp |
| Cold storage facility | 150,000 kWh/month | SGD 42,000 to 48,000 | 300 to 450 kWp |
| International school campus | 60,000 kWh/month | SGD 17,000 to 20,000 | 150 to 250 kWp |
Cost lines and prices
Budget depends mostly on the calculator and the number of case studies. The calculator asks for monthly bill, roof area, sector and operating hours, then estimates system size, capex, annual savings, payback and CO2 avoided. It turns anonymous visitors into qualified site survey requests.
| Item | Singapore market price (2026 ballpark) | Timeline |
|---|---|---|
| B2B site, 12 to 20 pages, fast and accessible | SGD 14,000 to 28,000 | 4 to 6 weeks |
| Savings and PPA calculator | SGD 7,000 to 15,000 | 2 to 3 weeks |
| 6 to 10 kWp case studies with data | SGD 2,500 to 6,000 | 2 weeks |
| PPA, leasing and green financing pages | SGD 1,500 to 3,000 | 1 week |
| CRM and tender form integration | SGD 1,500 to 4,000 | 1 week |
| Hosting, backups and monitoring | SGD 150 to 450 per month | ongoing |
| Total project | SGD 25,000 to 55,000 | 8 to 10 weeks |
Kolonell works with international clients from Dakar. A B2B brochure site without calculator sits in our grid: Starter 800,000 to 1,200,000 FCFA (EUR 1,220 to 1,830), Growth 1,200,000 to 2,000,000 FCFA (EUR 1,830 to 3,050), Premium 2,000,000 to 3,500,000 FCFA (EUR 3,050 to 5,340). An advanced calculator connected to a CRM is a simple custom application, 2,500,000 to 4,000,000 FCFA (EUR 3,810 to 6,100). Maintenance is 35,000, 75,000 or 120,000 FCFA per month. Languages and hosting are set in the quote. See our custom web application service.
Search visibility that brings in industrial buyers
B2B searches are few but valuable: 'commercial solar installer Singapore', 'solar PPA warehouse', 'rooftop solar factory Tuas'. One page per sector, solid technical content (sizing, structural loading, monitoring, maintenance) and an up-to-date Google Business Profile can reach page one within 6 to 9 months, because many installers rely only on tender portals.
Mini case study
Daniel, managing director of a C&I solar installer in Singapore, signs around 6 projects a year at roughly SGD 1,100 per kWp installed, with a 12% net margin.

He invests SGD 40,000 in a site with a savings calculator. If the site brings 2 extra 400 kWp projects a year, that is 2 × 400 × 1,100 = SGD 880,000 in revenue and SGD 105,600 in net margin. The investment is covered about 2.6 times in year one, and a single extra project still repays it.
FAQ
Should the calculator display a firm price?
No, show a range (for example SGD 1,000 to 1,300 per kWp) and an indicative payback of 5 to 8 years. The firm price follows the site survey, which creates the sales meeting.
How many case studies are needed at launch?
Six well-documented ones are enough: kWp, annual kWh yield, savings in SGD and a photo. Six data-backed cases beat 30 photos without numbers.
Should we feature PPA or capital purchase?
Both, side by side: in Singapore, a large share of C&I deals use zero-capex PPAs over 15 to 25 years. A comparison table helps CFOs decide.
What lead volume is realistic?
For a C&I installer, 5 to 15 qualified survey requests a month after 6 months of SEO is a realistic ballpark, with a 10 to 20% close rate.
Do we need online payment?
Not for the system itself. A paid feasibility study of SGD 500 to 1,500 can, however, filter out low-intent requests.
