Questions
Solar questions, answered honestly.
No hype, no invented numbers. If we don't have a verified figure, we point you to the official source.
Is rooftop solar free?
No. You pay for the system, but central and state subsidies can reduce your cost substantially. Subsidy amounts and eligibility change over time, so check our PM Surya Ghar and Solar Subsidy in Assam pages for the current official position.
Does solar generate power during monsoon and winter?
Yes. Panels keep generating in cloudy or rainy weather at reduced output. We account for seasonal variation when sizing and estimating your system.
How much roof space does a solar system need?
It depends on panel wattage and roof layout. Our panel area and system size calculators give an estimate, and a free site survey confirms the exact space needed.
Do you help with subsidy and net metering?
Yes. We assist with the PM Surya Ghar application process, documentation, and the APDCL net-metering formalities for your connection.
On-grid, off-grid or hybrid — which should I choose?
It depends on whether you need battery backup and how your grid connection works. Our guide to solar types explains the trade-offs before you decide.
How long does installation take?
Most rooftop installations are completed within days once approvals and materials are ready. Timelines vary with system size and APDCL processes, and we keep you informed at each step.
