  Solar water heaters convert sunlight into electricity. A solar panel installation can take one to three days, depending on the climate of your location.  Although the direct installation costs might be high, these systems pay for themselves over time by reducing your energy bills. However, solar water heating systems do have both advantages and disadvantages. These factors depend on many other factors like your geographical location, your type of residence, the service you use, etc. We thought of clearing up the pros and cons of installing a solar water heater to help you make a well-informed decision.

  How can you identify a good solar water heater? A good solar water heater 's first and foremost requirement is that it should have sufficient collector area for the capacity claimed. The Collector area used in the system determines the capacity of water heating. For example, in typical North Indian weather conditions, an sq. m. of collector area can be expected to heat around 50 liters of water at a temperature of 30-40° C on a sunny winter day. Typical flat plate collectors made in the country have an area of around 2 sq. m and thus can heat around 100 liters of water in a day. This proportion serves as a benchmark. The collectors should use suitable materials, and the absorbers should carry a good quality coating.The system should be mounted on a rigid structure and firmly fixed with the roof to prevent damage in high winds.
