The global concern on the negative effects of fossil fuels used in cars and for power production is getting bigger and bigger. As a consequence of this issue, solar energy becomes increasingly popular. Coming as a solution for this contemporary problem, solar homes are designed to reduce power consumption by using solar energy. There are many solar technologies as well as many design elements that can capture the energy generated by the sun.
- The Popular Choice: Solar Panels
The bluish-tinted solar panels are one of the most used solar technologies designed for houses. Solar panels differ from one another by the type of solar cell they feature. For example, the monocrysalline cell panels are crafted from silicon wafers that have been cut from a single silicon crystal therefore they are the expensive one. On the other hand, the polycrystalline cell panels are the cheaper option and the most frequently used one. Thin-film panels are the less efficient ones. It is very important to know that solar panels do not generate carbon dioxide and in the same time they reduce the power costs of a house.
- The Ingenious Choice: Solar Water Heating
There are many ways to include solar water heating into a home. The solar collector heats the cold water and directs the heated water into a storage tank. There are many types of solar collectors for water heating such as batch systems, flat-plate collectors and evacuated tube systems. Solar water heaters can be either passive or active systems. The passive system uses gravity, while the active systems use pumps to move the water.
- The Easy Choice: Design Elements
Materials and designs elements are another type of passive solar energy use because they can draw advantages from the heat and light of the sun. To benefit from solar energy, place the solar panels facing south in order to increase the amount of time the sun lightens them. For the southern portions of your house also use materials that capture solar energy and have larger windows. They will retain heat in the structure of the building for longer. You can use overhangs to cover the windows during the hot summer days. Still, not every element of passive solar design works for every environment. For example, they have no effect in places with long winters and short periods of sunlight.
