If you think solar panels cost too much, there are other ways to harvest solar energy and save energy without the high cost. You can install solar water heaters, also called solar domestic hot water systems can to generate hot water for your home. The good news is that they can be used in any climate and for free.
How does a solar water heater work? Solar water heating systems come with storage tanks and solar collectors. The storage tank is well-insulated and has an additional outlet and inlet connected to/from the solar collector. In a 2 tank system, the heater preheats water before it enters the conventional water heater. In 1 tank system, the backup heater and the solar storage are in one tank. The cost of a solar water heater usually is around $1,100.
