Is solar water heater working better and more efficient during summer than winter?
No. Performance of solar water heater bears a no relation to seasons because the principle of hot water produced by solar water heater is collecting solar radiation. Therefore, solar water heater can provides hot water even below -20°F condition. The different output of hot water between summer and winter is due to the length of sunshine. Improvement of inner absorbance coating is greatly enhancing the solar collector’s absorbance efficient and the ability of collecting solar infrared ray. Solar water heater can provide and meet almost all of a house hot water needs at all times.
