The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest, 122 PW, is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet. Most of the world's population live in areas with insolation levels of 150–300 watts/m , or 3.5–7.0 kWh/… WebApr 11, 2024 · 2.)It is cost-effective. Solar water heaters can save you a lot of money in the long run because they rely on free solar energy instead of using electricity or gas. In addition, they have low maintenance costs. 3.)It is reliable. Solar water heaters are very reliable and have a long lifespan.
