Solar Energy Facts - Solar Panels Facts

Solar energy is a technology that harnesses suns energy into a useable state.  This energy is converted through solar panels into electricity which you can use to light up your home, heat water or even dry clothes, cook or for attic fans.


Solar panels are a collection of solar cells which are made up of semiconductor materials.  Photovoltaic is the process of extracting electricity from the sunlight.   When the sunlight hits the cells, atoms release electrons which flow through the cells to generate electricity.  Solar panels are installed together with an inverter, a battery, a charge controller and  wiring structure.


Solar panels are installed on rooftops and in spacecrafts.


The solar panels are designed to face the sun all the time, and the more the sunlight, the more energy they are able to trap.  They are no harmful emissions from these panels and they are noise free, thus making them environmentally friendly. You will also be guaranteed constant supply of electricity.


Current research on solar cells has yielded more efficient semiconductors that can withstand weather extremes and still harness enough light to convert into electricity.  In fact, you can find mobile phones or communication equipment whose batteries are solar charged, and can therefore fit in different weather conditions.  It is also possible to install solar panels as part of your roofing rather than adding it as a separate structure.


Solar panels usually come with a 20-year guarantee and provide you with a 24/7 electricity supply.  Solar energy is measured in kilowatt-hours (kWh) and one kWh burns a 100w bulb for up to 10 hours.  Given this information, you can be able to estimate your power needs and install solar panels that meet or exceed your needs.


Solar energy is a green heating cost-effective alternative than you can access from anywhere in the world.  And whats more, it will save you money in the long-run and give you peace of mind since you do not have to pay a dime to the power companies and no blackouts ever.
