On farms, sometimes there are power problems, so you have to look for alternative energy options. The most progressive source of energy can be called solar energy. In this case, the choice is better to give reliability and durability of solar panels, rather than low cost.
Consumption of solar energy
Increasingly, they began to consider ultraviolet light as a source of energy for greenhouses. Some acquire a set of solar panels for buildings as backup power. Others completely decide to replace them with an electric current. In any case, this is a rather profitable and useful acquisition. Once invested in the purchase and installation, do not have to spend money on utilities.
Solar panels for trusses are installed on roofs or in free areas in the neighborhood and are panels with photovoltaic cells. With their help, and converts ultraviolet into current energy. In addition to solar panels, storage batteries are required that receive energy from the solar module through the converter. To the consumer, current flows through an inverter that converts it from DC to AC.
Types of batteries
Before deciding to install solar panels for farms, you should evaluate the characteristics of their species.
- The most common are single crystal, silicon. They are compact, light in weight and easy to install. Efficiency is about 22%, which is considered a fairly reliable indicator. A guarantee is given for a long service life (about 40 years).
- Thin film is in demand due to its low price, due to impurities in the composition of the metal. This affects the efficiency reduction (up to 12%) and the service life (not more than 10 years).
- Polycrystalline for reliability and utility - something in between the types of panels already described. Serves such modules for up to 20 years, giving an efficiency of about 17%. Affect these indicators of additions to silicon, taken from metallurgical waste.
When choosing solar panels do not take into account only the price. Durability, usefulness and power are also important indicators. Select panels should be based on your electricity needs, available space for installing panels and the amount of sunlight.
