A typical direct solar thermal system consists of collector, pipes and an insulated tank. A typical 100 LPD (litre per day) system is sufficient to provide approximately 100 litres of hot water at an average temperature of 65 C every day on all sunny days.
This helps save approximately 4 units of electricity daily (equivalent energy consumed by an electrical geyser) offering cost benefits of approximately Rs 4,000 per year.
TPS (ETC & FPC) solar water heaters are available in scalable multiples of 100. Large scale installations, for special applications can also be engineered.
