Solar energy is becoming increasingly popular as a source of energy for buildings. It is a clean and renewable energy source that can help reduce dependence on fossil fuels and protect the environment. The following explains how solar energy is used in buildings:
Photovoltaics: Photovoltaic modules convert sunlight directly into electricity. These modules are made of silicon cells that release electrons when exposed to sunlight. These electrons can be used as electricity. The solar system created can then be used to power buildings. Surplus electricity can usually be fed into the public power grid.
Solar thermal energy: Solar thermal energy is a technology that uses sunlight to heat water or air. The heated liquid can then be used to heat buildings or produce hot water.
Passive solar use: Passive solar use refers to the use of solar energy without technological aids. For example, the sun can be used to illuminate a building through large window fronts or to improve the indoor climate and energy efficiency of a building through the use of solar collectors and special heat storage.
Overall, there are many ways to use solar energy in buildings. Solar energy is not only environmentally friendly, but can also help reduce energy costs and increase independence from fossil fuels. However, investing in solar energy can also come with high costs. It is therefore important to carefully consider which solar technology best suits the specific needs of a building.
