Mainly different types of solar cookers and solar water heaters are available in global market. But solar cooker and solar water heater are two different device. So, my team made Two in One Solar Heating System. In this system solar cooking and solar water heating this two facility available in one device. It produces a good temperature for water heating and also food cooking. The major problem with One Solar Heating System is that it has not yet been tested in all the seasons. Two in One Solar Heating System concentrates light to a larger surface, so it is slightly more tolerant for marginal errors of alignment.
