The cost of electricity is constantly rising. In a rather fierce market, enterprises are forced to develop measures to reduce costs. Energy efficiency programs are being introduced everywhere at enterprises, and the principles of lean production are used, aimed not only at conserving resources but also at reducing the negative impact on the environment. Often, at enterprises, the load schedule on the power grid is not uniform; the peak of consumption occurs during the daytime, which makes solar power plants the most effective solution for most commercial facilities. In addition, the use of a solar power plant allows you to quickly and easily increase the input power at the facility or create a reliable backup of important nodes, the failure of which is unacceptable. If the object is located at a considerable distance from the centralized network, then it is possible to use autonomous solar power plants both independently and in combination with alternative sources of generation.
