Know before you build.
Q
Can apartment owners install solar?
Yes, if the consumer connection, roof rights, and association permissions are clear. Shared rooftop cases need additional coordination.
Q
Does off-grid home solar get PM Surya Ghar subsidy?
No. The subsidy applies to grid-connected rooftop systems using approved components and process.
Q
How much roof area is needed?
A practical thumb rule is around 80-100 sq ft per kWp, but final layout depends on shade, access, and mounting type.
