solar hot water
Solar hot water may be the most undervalued renewable energy source on the market. In relation to the off-grid home, solar hot water is a fundamental component for domestic hot water. Hot water is seventeen percent of the average home's energy consumption. Solar hot water systems typically cost a fraction of what a PV system costs with many residential systems needing only two panels.
Solar hot water can also power other household needs. For instance, a solar hot water tank has multiple coils within it to utilize the water for heating. These tank systems are designed with multiple loops to gain heat from solar panels and can be used in other ways such as radiant heating a floor or in many other applications. Overall, when it comes to energy costs per dollar, solar hot water outperforms other technology.
