The primary goal is to reduce greenhouse gas emissions to prevent an increase in global warming of 2ºC compared to the period of the first industrial revolution. The analysis of photovoltaic systems and photovoltaic modules through the solar power plant project will show the phases of power plant construction, from idea to realization with an emphasis on technical, economic and ecological aspects. Designing and simulating the solar power plant of the Macan family house in the PV*SOL program determined the optimal number of solar modules of 12, each with a power of 450 Wp. According to the consumption budgets and the total cost estimate of the construction of the solar power plant, the investment return time is predicted to be six to seven years. It is realistic to expect a reduction in electricity costs, a reduction in carbon dioxide emissions and an increase in the energy independence of the housing unit. When we talk about the production of electricity from a solar plant, the disadvantages in the context of global climate change should not be ignored. Building a solar power plant is a profitable investment in the long term. In addition to economic justification, the negative impact on the environment is reduced, and thus the justification of planning and analysis of solar power plant projects is proven. However, it is necessary to reduce the negative impacts of the production of solar panels.
