New approaches to implementing strategies of energy and shipbuilding industries forge conditions for the technological development of alternative energy sources in water transport. The operating experience of the solar power plant for "Eco-wave" ("Ekovolna") catamaran was analyzed. A block diagram of a solar power plant was presented. A visual scheme was developed that visualizes the picture and types of defects that arose. As a result, it was revealed that the key reason for the failure of the solar modules of "Ekovolna" catamaran is the overheating of photovoltaic cells. This leads to rapid degradation of the material. Based on experiments conducted using a test photovoltaic system, it was found that at noon the temperature of solar modules in the climatic conditions of Astrakhan reaches high temperatures, i.e. more than 70 C. A water-cooling system for solar modules was developed that does not require any vessels for storing the working fluid, since the use of seawater as a refrigerant was suggested. A complete set of components for a solar power plant was proposed. Electricity generation of a solar power plant using RealSolar software was calculated. Generation of electricity was shown to completely cover the energy costs for the electric drive of the catamaran in the period from May to August due to solar modules. With Polysun software, the reduction of CO2 emissions into the atmosphere was assessed. The proposed catamaran solar power plant project is expected to reduce CO2 emissions into the atmosphere by 7171.5 kg per year.
