Since the conventional method of producing energy is always hydro-electric or nuclear, resources can be diminished at a gradual rate, if not faster. Technology should supply us with cheap and renewable energy sources to cope up with our growing population and changing lifestyles. Other alternative solutions to renewable, environment friendly energy sources are wind mills, geothermal sources, and the most popular solar panels.
Solar panels basically harvest the sun's rays and convert them into usable electric current that common appliances can use. Solar panels can usually be found on remote areas where electric lines cannot reach them. Since solar panels belong to a high form of technology, its manufacturing is usually intended for upper class users. But since technology is advancing rapidly, and manufacturer find a way to develop solar panels for the mass population, cheap solar panels are available for consumption.
Cheap solar panels are best purchased directly from a manufacturer. Or even better still; get them at the main supplier. This eliminates the middle man and gives you the factory price. It also gives you the warranty needed if the product breaks down.
Chinese manufacturers are well known to produce quality solar panels at a bargain price. Yingli and Suntech are two manufacturers who are reputable of producing excellent solar panels. They can be reached via their website. You might have to wait for some time for your product to arrive since delivery from China can take thirty days or more, so be patient.
The cheapest method for having a solar panel is to build it yourself. To do this, you should have technical know-how on basic electronic assembly and configuration. You need soldering iron and materials that are to be used with that tool. You should be able to make a frame that will hold the solar cells. This setup will become the solar panel. Weather could damage your customized solar panel so you should consider installing protective layers like plastic covers.
Since a twelve volt battery is commonly used to power any twelve volt appliance, you should calculate how many solar cells are needed to charge up the battery. Basically, two solar cells can give out one volt of electricity. So based from this, you need thirty six solar cells that are connected to each other to produce eighteen volts of electricity. Eighteen volts should be used to charge a twelve volt battery.
In making your own solar panel, it is very important to get a guide or a manual. You should be able to solder and connect all the parts correctly, or else your solar panel will malfunction and all your work will go to waste. Making your own solar panel is definitely the cheapest way than buying from a manufacturer. But you should properly maintain it to have it function for a long time.
