A solar cell is a photovoltaic direct current generator that uses the effect of converting solar energy into electricity. They use the property of semiconductors based on silicon crystals.
Instructions
Step 1
Keep in mind that there are several determining factors when choosing a solar panel system that works for your home. Firstly, these are the climatic characteristics of the area in which the dwelling is located. The duration of the sunshine above your house and battery depends on this, and, accordingly, the time for accumulating solar energy. Determine how suitable your terrain is for placing solar panels on the irradiance map
Step 2
When choosing a solar panel, consider the amount of heat that you want to receive as a result. The best option is a battery that can cover forty to eighty percent of your heat needs. Systems that are less efficient can be very expensive. At the same time, it is also necessary to consider the possibility of designing and calculating the capacity of the system. This guarantees you the reliability of the resulting system and the ability to withstand force majeure (disconnection from the power source, bad weather). Entrust these calculations to specialists.
Step 3
Pay attention to the manufacturer of the solar battery, as well as to the material from which the photoelectric cell of the modules is made. It can be polycrystalline or monocrystalline silicon. The price, efficiency and battery life depend on this. Monocrystalline silicon is a material that is resistant to various aggressive influences, the efficiency of batteries made from it can increase up to 20%. Multicrystalline batteries made from polycrystals, but named so in order to mislead the buyer, also appeared on the market. An example of the use of polycrystalline elements is garden lanterns, which last much less in the second season of use.
Step 4
Consider also that the thickness of the photovoltaic cells will ensure the emission of electrons for life, but the thickness of the foil only ensures the cheapness, which is what Chinese manufacturers are striving for. Pay attention to the structure of the glass surface, if it is textured, then the input radiation power will be increased by 15%, and due to this, the efficiency of the solar battery will also increase, especially in the cloudy season.
