In the near future, systems for the joint production of electric and thermal energy should become one of the vectors for the development of the energy sector in Russia. Compared with existing monopoly tariffs, cogeneration can significantly reduce the cost of energy consumed, as well as solve the important problem of network unloading during peak loads. Cogeneration plants have a greater resource potential, as well as advantages in reliability. The monopolization of the electricity market simply forces the Russian industrial, agricultural and civilian consumers to acquire cogeneration plants.

In the article solar modules of different design are considered. Planar and high-voltage solar modules with extended service life are presented. These modules have an increased service life of up to 40-50 years, high-voltage modules have an increased electrical efficiency up to 18 % and can be used in cogeneration plants with concentrators of solar radiation. Solar tiles presented in article can be made from recycled materials and the additionally installed concentrator reduces the number of solar cells used and makes it possible to obtain heat energy at the output. Compact folding solar modules considered in the article allow to charge electrical devices away from electrical networks. Also in the article described photovoltaic thermal solar module with paraboloid-type concentrator for solar cogeneration plants. Such an installation, along with electricity, allows to get warm water at the outlet for the power supply of autonomous consumers or in parallel with the network. Each type of solar modules is used in a stationary heat and electric power supply or mobile power generation. Under consideration were accepted modules designed and fabricated at the Federal Scientific Agroengineering Center VIM, Moscow, Russia. Surveys on the development, research and production of solar modules of various designs has been efficiently conducted over the last few decades.
