The distributed systems refer to those Systems that are installed at or close to the place where electricity is utilised, as opposed to central systems that provide electricity to grids. In simpler terms, a distributed system is a solar system for a home.
Distributed solar photovoltaics (PV) are PV systems with a capacity of less than 1 megawatt that are often installed on rooftops. Traditional electricity-generating methods, such as coal, oil, and natural gas power plants, are replaced by this solution.
How are the first, second, and third-generation solar cells different?
A solar cell converts solar energy into electricity in a PV system. Three generations can be distinguished among solar cells. The majority of solar cells on the market today are first-generation and are made of single- or multi-crystalline silicon.
Thin-film solar PV cells, which are second-generation solar cells, are more effective and have greater capacity factors. High-concentration PV cells, dye-sensitized solar cells, and organic solar cells are only a few of the third-generation solar cell technologies still being developed.
By 2050, less than 10% of the electricity would be produced by PV (including rooftop and utility scale), according to the majority of past adoption scenarios. However, some recent scenarios have suggested that by 2050, about 60% of all electricity might come from solar PV due to the rapid recent adoption of solar PV in many nations, rising solar cell efficiencies, and quickly falling costs.
What is the potential impact of rapid adoption of rooftop solar?
Sunlight is abundant, and future developments in battery and PV technology should continue to spur adoption even in the absence of particular legislative measures, giving solar an exceptionally bright long-term outlook.
The financial outcomes demonstrate that widespread deployment of rooftop solar is commercially feasible and will generate a sizable return on investment. Rapid adoption will also have a significant impact on reducing greenhouse gas emissions worldwide.

However, a number of challenges must be fixed before rooftop solar may be widely adopted. Solar PV does not always produce electricity when consumers need it since sunlight is sporadic. This means that energy storage systems or dispatchable energy sources like coal and natural gas must frequently be constructed alongside PV, and demand must adjust to match periods of ample supply.
Due to the fact that some inputs may only be obtained as by-products of mining for other metals, distributed solar PV may also encounter material limitations. System design modifications could be used to solve this problem.
