Efficiency Facts About Solar Energy Panels Efficiency Facts About Solar Energy Panels
The efficiency of solar energy panels is measured by the amount of energy we get after it has been out in the sun. While solar energy has been around for a long time, public use is relatively new. Calculations can be made, to see how much solar energy is needed to power our homes. Running an energy efficient house, that is environmentally friendly, through solar energy panels sounds great. Everybody wants to be good to the environment, and wants a more energy efficient house. You need to see just how efficient solar energy panels are. If you are looking to go green, stop paying electric bills, and use the power from the sun, here are some things you need to consider.
Calculate the Energy you Use
Seek a professional who can calculate just how much electricity you use. You can find out how much is needed to heat your water, run your lights, and even your hairdryer. This will be very important to know when deciding just how many solar energy panels you need.
Solar panel cost
Installing solar energy panels can be very expensive. Estimates show that the initial cost can be between $10,000 and $30,000. This means that it could take a while to see a profit. You might be saving money on electricity, but you could be paying back a loan, as well. There are kits available to install them yourself. There are also government grants available to the public. The cost of solar energy panels and their efficiency are directly related.
Electrical Energy Produced
Aside from the cost, this is the most important thing that you need to know. The amount of electrical energy basically depends on the climate where the solar panel has been installed. As such, only 20% of solar energy is transformed into electrical energy. There are continuing studies being conducted to improve this number, but right now this is the number researchers have confirmed. You will not be using a power grid, so there is no limit to how much you use. It is said that solar panels can produce 1000 watts of electrical energy per square meter on a sunny day.
Cost of Maintenance
Another factor in the efficiency of solar energy panels is the cost it takes to maintain them. If you are saving money on electricity, but spending money on repairs, your house is not being very efficient. Solar energy panels have no moving parts, and that does cut down on the risk of repair. On the other hand, if something does go wrong, you just cannot go down to your local hardware store and pick up a replacement part. Parts can be expensive, and there will be a delay in getting them.
Long Term Benefits
This is where you see the efficiency of solar energy panels pay off. In the long run, your house will indeed be more energy efficient. You will cut out electricity bills, and see the savings begin to mount up. Solar energy is the way of the future. More importantly, with solar energy panels you will never use up all of the energy of the sun.
