How does the solar calculator work?
The calculator estimates the system size (kWp) from your roof area and type, multiplies it by the typical annual yield for your region in Israel, and applies orientation, shading and performance factors. From the annual output it derives revenue at the relevant tariff, the payback period and the environmental saving. Every coefficient is tunable to match market conditions.
