2A solar panel (also solar module, photovoltaic module or photovoltaic panel) is a packaged, connected assembly of photovoltaic cells. The solar panel can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications.
Each panel is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. Solar power plants can be installed on ground, or on rooftops, or even onto walls with certain inclination, in order to catch as much as possible direct sun rays during the day. The orientation and tilt has to be calculated according to the location, exposition and latitude, avoiding shadows from eventual buildings or trees in the surrounding. With solar-generated electricity everybody can :
Cut Electricity bills: Sunlight is free, so once you’ve paid for the initial installation your electricity cots will be reduced.
Cut carbon footprint: Solar electricity is green renewable energy and doesn’t release any harmful carbon dioxide or other pollutants. A typical home solar PV system could save over a tonne of carbon dioxide per year – that’s more than 30 tonnes over its lifetime.
