Solar Panel Facts

Solar panels are special devices capable of capturing the light emitted by the sun and convert the absorbed light into electricity. Solar panels are the most important equipments of the solar power system. Therefore, one should always choose the highest quality of solar panels regardless of the selection of the installation process.
The main concern when you purchase or think about buying solar panels is the cost and placement of these devices.
The amount of solar electricity you will need to generate greatly depends on the size of your household, and the equipment contained within it. There are many resources on the web which help you decide the capacity of electricity you will need to generate and therefore the amount of the panels you should buy.
When you buy cheaper panels, they will generally have a much lower output, and a lower efficiency, than when you buy more powerful panels and are not recommended for home power supplies. Today solar panels can be obtained for as low as $3.75 per watt. The $3,600 would thus be available to buy a 900 watt solar electric panel array. If one's home receives an average of 4-5 peak hours of sunlight per day, then this array would generate 3.6 kWh to 4.5 kWh per day. In fact, if a home in India typically consumed 3-4 kWh per day -- that would be one 1 kWh AC unit continuously running for 3-4 hours then the house could entirely subsist on the 900 watt solar electric panel array.
There are many advantages of installing solar panel. This offers you the access to free and clean source of energy. You can check the environment pollution and reduce your fuel and electricity bills.
- During electrical outages, solar panel consumers are still capable of using their power without any disturbances.
- Solar panels don't use moving parts and need very minor maintenance.
- Solar panel installations are often eligible for tax credits and rebates for home and business owners, depending on which state you live in.
Solar panels can be installed on the roof of your house. Look for websites that track the position of the sun in the sky all year round to take advantage of the panel's peak performance. Also make sure that all hindrances, such as branches and trees, are detached so that the panels can get the maximum light and connected to the in-house heating system known as thermal solar systems. The collector of this system is capable of absorbing solar radiation and converting it into heat, which is transferred to the heat from the collector to the water tank.
Photovoltaic systems are the solar panels capable of producing electricity. An electrical field is created by placing a positively charged layer of silicon against a negatively charged layer of silicon. When sunshine falls on this field, electric charge is created. Then with the help of conductors, this charge is conducted to power household appliances.
