Abstract: Basic diagram of the plant with buffered storage battery and the volt–ampere characteristics of the photoelectric plant at intensity of solar radiation 900, 710, 660, 300 and 225 W/m2 are given. It was determined that at using buffered storage battery current variation in the electrolyzer circuit does not exceed of 2–6 A. The voltage is changed between 12.8–14.0 V. Availability of buffered storage battery is ensured power supply in conditions of changing solar radiation intensity. Also basic diagram of the electrolysis plant with small-size regulator of pressure difference is given. It is shown that the regulator provides production of hydrogen and oxygen with high purity (hydrogen—99.98%; oxygen—99.85%) and safely works in wide interval of changing solar radiation intensity.
