For your home

Solar vs your electricity bill
What your bill looks like the year after you install.
The figures shown by this calculator are directional estimates produced from typical system costs, average solar generation for your area, and published tariff and subsidy structures. They are not a quote and not a commitment. Your actual generation, savings, subsidy and payback depend on your roof or site, its orientation and shading through the day, your sanctioned load and consumption pattern, your DISCOM's current tariff, and the scheme rules in force on the date of your application. Government subsidy rates and electricity tariffs change. Origian Power confirms every figure with a site survey before issuing a quotation.
