Abstract

The problem of decarbonization of human activity is one of the main ones in the conditions of the growing threat of global warming. It is solved in different ways in all spheres, first of all - in the fields of engineering and technology. As part of this problem, the transport fleet could not be aloof from its solution. One of the ways of its solution is the use of solar electricity power. However, marine solar energy has not been widely implemented, which requires an analysis of this problem. Its implementation is the main goal of the performed work, and the search for the most effective implementations of ship solar energy and the development of recommendations based on this analysis is its scientific novelty.
Work result: It is shown that the energy capacity of photovoltaic solar systems of the economical class is 0.175 ... 0.185kW/m2, and the annual average, taking into account sunny days, time of day, operating conditions and location of the system, decreases to 0.02 ... 0.03kW/m2, which significantly reduces possibilities of their use in the transport fleet. For the real square of placement of ship solar batteries, a complete replacement of the main engine with them is possible only for pleasure yachts and excursion vessels. For the transport fleet, it is not possible and can be used only as an additional one, capable of replacing 3 to 6% of the main engine’s power. However, this is more than the capabilities of other ship systems that have reached a high level of perfection, which limits their efficiency growth to 1%.
Conclusion: Not using solar energy systems on the transport fleet is equivalent to waste.
