Electricity costs rarely go down. If your building or local rules allow individual or shared solar panels on the roof, you may have the option in future to reduce bills significantly.
Asking upfront—“Society solar panels allow karti hai? Common system ya individual possible hai?”—tells you how flexible things are. Some societies already have shared solar for common lights or lifts. Others strictly forbid individual setups for structural or legal reasons.
If you’re someone who thinks long-term and likes the idea of greener, cheaper power, this detail can actually affect which building you choose. Roof policy can shape your energy options for years.
