Solar thermal Systems use sunlight to heat water - for domestic use, swimming pools and more. A typical direct solar thermal system consists of collector, pipes and an insulated tank.
A typical 100 LPD (liter per day) system is sufficient to provide approximately 100 liters of hot water at an average temperature of 65 °C every day on all sunny days. This helps save approximately 4 units of electricity (equivalent energy consumed by an electrical geyser) offering cost benefit of approximately Rs 4,000 per year.
