The idea
A solar water heater is the quiet workhorse of green tech - simple, no moving parts, and it removes your geyser (one of the biggest power-hungry appliances) from the bill.
What to know
Systems are sized in LPD - litres per day. A family of four typically needs 100-150 LPD. Evacuated tube collectors (ETC) work well even in NCR winters. Once installed, running cost is essentially zero; most owners recover the cost in two to four winters.
