Solar power is energy, usually in the form of electricity, which comes from sunlight. The scale of the energy conversion project usually determines the technology used. Small systems, like those used to power homes or small businesses usually use photovoltaic cells. Businesses that produce a lot of energy, such as utility companies, often use Concentrated Solar Power systems. Since solar power cannot be produced in the absence of sunlight, some type of energy storage is needed if electricity is to be used at night time.

Subsidies are financial incentives, usually paid by governments to encourage the production of something. There are many reasons that a particular product might be beneficial to the community, but not economically feasible to individuals and businesses. Many products are subsidized to support local businesses, reduce the amount of imported goods, provide employment and encourage environmentally friendly practices. The energy industries (coal, oil, nuclear, alternative) have always worked in an environment where subsidies have been used. In recent years the trend is to encourage renewable energy sources (such as solar, wind, biomass) at the expense of fossil fuels such as coal and oil. Alternative energy subsidies include Feed-in Tariffs and financial incentives to photovoltaics.
