Harnessing Star Plus Energy dates back more than two thousand years, but it’s gained momentum and accelerated rapid growth in the last hundred. Today, solar power systems generate electricity using photovoltaic cells that convert sunlight into direct current (DC).
Each PV cell contains a semiconductor, often made of silicon. When the sun hits a solar panel, it knocks loose electrons, which creates an electric field that runs through metal contacts at the top and bottom of each cell. This produces electricity, which flows through wires connected to an inverter. Inverters transform the DC electricity into AC electrical energy, which powers appliances and other devices in your home.
Solar Energy Solutions
For large installations, many solar-power systems have a dedicated weather station that tracks weather forecasts alongside on-site solar irradiance and wind data. These sensors allow operators to stow arrays when weather conditions threaten production. But more comprehensive technologies are needed, combining meteorological predictions with sensors like accelerometers and video to identify problems early and respond quickly. Machine-learning algorithms are a promising solution.
The best homes for solar energy have lots of daily sun exposure, and they must be free of obstructions — including tall trees and surrounding buildings — to take advantage of the maximum available sunlight. Also, the cost of a solar system can vary greatly by region. For example, labor costs are higher in some areas, and the quality of equipment can influence your savings. Depending on your financial situation, you may want to consider an operating lease option instead of purchasing the system upfront.
