Solar power helps in reducing the effects of global warming. Global warming is proven to be a threat to the earth’s ecological system and the survival of countless species. Luckily, decades of research have led to efficient solar panel systems that create electricity without producing global warming pollution. Solar power is now very clearly one of the most important solutions to the global warming crisis.
Solar panel electricity systems, also known as solar photovoltaic’s (PV), capture the sun’s energy using photovoltaic cells. These cells don’t need direct sunlight to work – they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.
One of the main benefits of solar power to you the consumer is that you can either use the electricity generated in your own property to sell it back to your electricity provider for later use. In effect your electric meter will run backwards when you are producing solar powered energy & forward when you are using the electricity.
HOW DO SOLAR PANELS CELLS (PV) WORK
PV cells are made from layers of semi-conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced. Groups of cells are mounted together in panels or modules that can either be mounted on your roof or on the ground.
The power of a PV cell is measured in kilowatts peak (kWp). That’s the rate at which it generates energy at peak performance in full direct sunlight during the summer. PV cells come in a variety of shapes and sizes. Most PV systems are made up of panels that fit on top of an existing roof.
THE MAIN BENEFITS OF SOLAR ELECTRICITY
• Cut your electricity bills. Sunlight is free, so once you’ve paid for the initial installation your electricity costs will be reduced.
• Get paid for the electricity you generate. The UK government’s Feed-in Tariff scheme pays you for the electricity you generate, even if you don’t use it.
• Sell electricity back to the grid. If your system is producing more electricity than you need, you can sell the surplus back to the grid through the Feed-in Tariff scheme.
• Cut your 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 and a half of carbon dioxide per year – that’s more than 30 tonnes over its lifetime.
Solar PV needs little maintenance & should typically last you 25 years or more. You just need to keep the panels relatively clean and make sure trees don’t begin to overshadow them. In the UK panels that are tilted at 15° or more have the additional benefit of being cleaned by rainfall to ensure optimal performance.
In a recent survey of customers who had solar panels fitted for over 1 year found that the average reduction in their annual electric bill was 37%, with 25% of those questioned enjoying savings of 50% and over.
