High-Efficiency Photovoltaics and Why Now is a Great Time to Make the Switch
High-Efficiency Photovoltaics The demand for clean electricity is growing. At the same time, fossil fuels represent a significant source of energy for generating electricity. Soil and atmospheric pollution are major issues, as is the need to reduce our dependence on finite natural resources. These concerns have led to a greater demand for alternative energy sources. Photovoltaic (PV) technologies, which convert sunlight directly into electricity, have become increasingly attractive. Thanks to significant price reduction and efficient manufacturing, the cost of PV electricity has dropped. In fact, it's now comparable to that generated by traditional power plants. There is more than one way to produce electricity with a PV system. A typical arrangement involves placing large solar panels on the roof of a building. The solar panels absorb sunlight and convert it into electricity that is stored in a battery bank. These systems provide electricity on demand, but they require a lot...
