Solar hot water systems use sunlight to heat water. In low geographical latitudes (below 40 degrees) from 60 to 70% of the domestic hot water use with temperatures up to 60 °C can be provided by solar heating systems. The most common types of solar water heaters are evacuated tube collectors (44%) and glazed flat plate collectors (34%) generally used for domestic hot water, and unglazed plastic collectors (21%) used mainly to heat swimming pools. A solar water heating system has two types of Flat Plate Collector and Evacuated Tube Type System.
Flat Plate Collector (FPC) Solar Water Heater is the conversion of sunlight into renewable energy for Water heating using a solar Flat Plate Collector (FPC). Solar Water Heating systems comprise various technologies that are used worldwide increasingly. In an FPC type solar water heating system the storage tank is horizontally mounted immediately above the solar collectors on the roof. No plumbing is required as the hot water naturally rises into the tank through thermosiphon flow. FPC systems are designed to deliver hot water for most of the year. The type of glass used in flat plate collectors is almost always low-iron, tempered glass. such glass can withstand significant hail without breaking, which is one of the reasons that flat-plate collectors are considered the most durable collector type.
We offer our clients an exclusive range of ETC type solar water heaters. According to the thermos siphon process when the sun rays strike the solar tubes, the water inside tubes get transferred in the hot water storage tank due to lighter weight. This phenomenon happens in the majority of a period of sunlight intensity. In India, it is mostly from 10 am to 4 pm. Due to the circular surface of the tube ETC type solar water heaters give higher efficiency. It also works well in winter (Cold) climatic regions ETC type solar systems are also suitable for hard water than flat plate type solar water heaters. Evacuated tube collectors (ETC) are a way to reduce the heat loss, inherent in flat plates. Since heat loss due to convection cannot cross a vacuum, it forms an efficient isolation mechanism to keep heat inside the collector pipes. Since two flat glass sheets are generally not strong enough to withstand a vacuum, the vacuum is created between two concentric tubes.
