People's awareness of environmental issues has been becoming greater and greater with news of global warming and other environmental stresses. At the same time awareness of renewable energy like solar power has been increasing. They can now provide even residential homes with cost-effective means to power their homes and help to reduce pollution due to energy production.
If you are looking to put up a solar energy system in your home, you'll want to make sure you can make a set of panels that will last a long time. Here are a few tips about how to choose solar panels and what you should look for in residential solar panels.
The size of the solar panels is important so that you have a suitable amount of power for your house. The amount of electricity certain solar panels produce is expressed in watts. It is is actually a rate of electricity production in watts/hour.
You'll find that the watts of a panel is also going to affect the size. The higher the watts, the larger the panel is going to be. It's important that you get panels big enough to cover the various appliances that you have within your home. Also, remember that the higher the watts, the higher the price will probably be.
Take a look at efficiency when you are looking at residential solar panels. This refers to how effective the panel actually is as it takes the light from the sun and turns it into electricity. Just remember, no matter the efficiency, which can be important, if you have a 100 watt panel, it will still be providing you with 100 watts of electricity.
You should also take a look at the warranty and the longevity of a solar panel when you are making your choice for a home system. It's important that you choose panels that are going to be durable, especially since they'll spend their time outside. You don't want panels that are going to take a lot of maintenance or that will quickly break down.
Take a look at the warranty. Many come with 10 year warranties. If this is the only warranty it comes with, make sure it will pay for itself in that time. However, in many cases the solar panels that come with a 25 year warranty are the better option for you.
The cost of solar panels is still relatively high compared to that of traditional energy sources and even most renewable energies such as wind power. They are low-maintenance, however and once installed you know your investment is ensured. You can also get grants from the government in many countries that will cut your costs for you.
There is more to think about than the cost of the panels per se. There are also the savings to be had by using these solar panels to power your home. Keep the long view in mind - if it makes sense over the life of the solar panels, then you are looking at a good deal.
