Assume that in the United States, photovoltaic cells cost 800 per square meter to install. Also assume that the average person needs 25 square meters of photovoltaic cells to supply the electricity that he of she needs. The cost of a photovoltaic system is high. Besides cost, what else would you consider when thinking about installing photovoltaic cells for your home?

A) Efficiency: Consider the efficiency of the photovoltaic cells in converting sunlight into electricity. Higher efficiency cells may generate more electricity with less surface area, potentially reducing installation costs.
B) Location and Sun Exposure: Assess the location of your home and the amount of sunlight it receives throughout the year. Optimal sun exposure can maximize the energy output of the photovoltaic system.
C) Maintenance and Lifespan: Evaluate the maintenance requirements and lifespan of the photovoltaic cells. Understanding maintenance needs and longevity can help estimate future costs and overall value.
D) Government Incentives: Research available government incentives, such as tax credits or rebates, for installing photovoltaic systems. These incentives can significantly offset the initial installation cost and make solar energy more financially viable.
