Have you ever used solar water heaters in your home? Besides heating, what other uses does solar energy have?

Reading during the day

During the day, sunlight provides us with light. But it should be noted that reading under strong sunlight is harmful to vision.

Advantages of solar energy

First: The energy potential is huge. It is estimated that the sun will be enough to supply humans on earth for billions of years in the future. It is truly inexhaustible.

Second: Solar energy is available everywhere and is easy to use and safe. There is solar energy everywhere on the earth, which can be developed and utilized locally without transportation problems. It is especially valuable for rural areas, islands and remote areas with underdeveloped transportation.

Third: Solar energy is a clean energy source. During development and utilization, no waste residue, waste water, waste gas, or noise will be produced, and it will not affect the ecological balance. Absolutely no pollution or public nuisance will be caused.

Inadequacy of solar energy

First: it is difficult to collect and often requires a large lighting and heat collection surface to meet the usage requirements, which makes the device occupy a large area, use a lot of materials, and increase the cost.

Second: The weather has a great influence and is easily affected by factors such as region, climate, season, and day and night changes. It is sometimes strong, sometimes weak, and sometimes not available, which brings a lot of difficulties to use.
