TOMSK, Feb 24 – RIA Tomsk. Scientists of Tomsk Polytechnic University (TPU) have developed a hybrid solar energy storage system for a gym in Baghdad, which is 20% cheaper than analogues, the university's website reported on Wednesday.

Despite the fact that Iraq is rich in oil, this country is energy deficient and has to import electricity. There are also problems of underdevelopment of electrical grid in remote areas, so the issues of using renewable energy resources are very relevant, they say in Polytechnic.

"TPU scientists conducted a study and presented the concept of a hybrid solar energy storage system based on a photovoltaic installation with electrochemical and thermal storage for a sports hall in Baghdad (Iraq). According to preliminary estimates, the development is 20% cheaper in total than analogues", – the statement said.

The installation collects and stores electricity in batteries, and also accumulates solar energy in the form of heat energy from heated water. It consists of an array of photovoltaic modules that convert solar energy into electricity, which is accumulated in electrochemical batteries with the help of a charge controller and supplied to the consumer through an inverter.

The thermal part of the installation, which provides heating of water, is a thermally insulated water-heating boiler with electric heating, powered by the same photovoltaic modules through a special thermal controller, bypassing the batteries.

Solar energy is accumulated by a combined method: in electrochemical accumulators and cheaper heat storage water boilers. In the conditions of Iraq, it is possible to reduce the cost of the solar energy storage system by 20%. As a result, the cost of photovoltaic electricity for a sports hall in Baghdad was estimated to be below the national average electricity tariff.

"Photovoltaic energy is very uneven, since it directly depends on the seasons, time of day and weather conditions. Nevertheless, the advantages of photovoltaic technologies allow obtaining energy at lower intensities of solar radiation compared to direct heating of a solar collector", – the report quotes TPU professor Boris Lukutin, with whom a graduate student of the TPU School of Energy & Power Engineering Karrar Hameed Kadhim worked on the study together.
