Sizing a solar system correctly is the difference between great returns and wasted investment. Here's how we do it.
Start with your bill
Your monthly units of consumption drive the calculation. As a rule of thumb, 1 kW generates roughly 4 units per day in India.
Check your roof
You need about 100 sq. ft. of shadow-free area per kW. Roof orientation and tilt affect output.
