Following days of research over the Internet, Heather zeroed in on an American company. Committing to an upfront cost of Rs 4 lakh, Heather got four solar panels installed on her slanting rooftop and thus began her series of never-ending ordeals. “You think that you did something good for the environment till it backfires on you.

In next few minutes, we were in Mavallipura, one of the fifteen villages administered by…
