What is an ETC solar water heater?

ETC stands for Evacuated Tube Collector. It uses a series of glass vacuum tubes to absorb solar energy. Each tube has an inner and outer glass layer with a vacuum between them, which minimises heat loss — making ETC systems highly efficient even on cloudy days and ideal for Indian climates.

How many people can a 100 LPD solar water heater serve?

A 100 LPD (Litres Per Day) solar water heater is ideal for 2–4 people. For a family of 5–6, a 150–200 LPD system is recommended. Hotels and apartments typically require 500 LPD to 5000 LPD capacity.

Does ETC work on cloudy days?

Yes. ETC solar water heaters work on diffuse radiation and can heat water even on overcast days, though at reduced efficiency. Most ETC systems include an electric backup heater for consecutive cloudy days.
