NTG STUDIO WEBShort answer
A solar calculator asks for the monthly electricity bill, outage hours and essential equipment, then estimates the recommended capacity, savings and payback period. It then offers a technical visit or monthly financing. The visitor leaves with a figure and you receive a qualified project.
Key takeaways
- Visitors want a figure before talking to a salesperson
- Three questions are enough for a first estimate
- Monthly financing removes the purchase-price barrier
- Online production monitoring builds loyalty after installation
Power cuts and the cost of generators are pushing many homes, shops, clinics and factories towards solar. Competition between installers is intensifying. The website that wins gives visitors a concrete figure within a minute.
Why a calculator
Visitors hesitate to call a salesperson "just for information". They first want to know if solar pays off for them. The calculator answers immediately and sends you a qualified request: consumption, budget, building type, location.
The right questions
- Average monthly electricity bill
- Average daily outage duration
- Priority equipment to power (refrigeration, pumps, IT, air conditioning)
- Building type and available roof
Three or four questions are enough. Every extra question makes visitors give up.
The result
- Recommended capacity in kWp and battery size
- Estimated monthly savings
- Payback period in years
- An example kit and price range
- Monthly payment if financed
The SolarKam demo presents this calculator. The result always states it’s an estimate, confirmed by a technical visit.
Conversion
After the result: "Get the detailed study on WhatsApp" and "Book a technical visit". The visitor has already received value, so they share their number more willingly.
Financing
The purchase price is the first barrier. Show a financing or lease-to-own monthly payment in the simulation. The application is completed online.
Proof
Completed installations presented by customer type (home, clinic, factory, farm) with photos and installed capacity. Detailed warranties. Maintenance contracts.
Monitoring after installation
An app or customer area shows production and savings in real time. Satisfied customers share their figures, and monitoring detects faults before they do.

Frequently asked questions

Can we offer instalment payments online?
Yes, by showing monthly payments in the simulation, with a financing application to complete online.
