Solar with battery questions
What is the difference between hybrid and off-grid solar?
A hybrid system keeps your grid connection: panels cut your bill through net metering and a battery runs essential loads in a power cut. An off-grid system has no grid connection, so the panels and battery must cover your whole use, including cloudy days.
Is there a subsidy for solar with a battery?
For grid-connected systems, yes. The PM Surya Ghar subsidy is worked out on the solar panel capacity, and the battery is not subsidised. Off-grid systems are not eligible.
How much roof space does it need?
MNRE says about 10 square metres of shadow-free area per kW. A 3 kW system needs about 30 m², roughly 320 sq ft.
Where do the sun hours come from?
