Are you looking to save some electricity bills? What if there is a power collapse and you are left in the cold? Well, there is a great option for you and that is why not build your own solar panels? This will help you to save electricity and help you in your hour of need. Solar panels are panels which take sunlight and convert it into electricity and it is an environmental friendly way of doing so. You can build your own solar panels too in the following way:
1. Get cheap solar cells from any site –
buy a couple of solar cells not for more than 1.3$ per watt. You will get Chinese cells which have good performance, less price but no guarantee, Japanese cells which are well priced and give good performance along with good guarantee but the best are American cells with good performance high price and well guaranteed. Now it is up to you to decide which you would use and which would suit your budget.
2. Get the right tools –
after getting your solar cells now get yourself some important tools like a soldering iron, solder, solder flux for getting the grease off the wires, a saw, wooden board and glasses to protect your eyes while soldering, along with a multimeter to measure voltage. Last but not the least a pencil and a ruler.
3. Plan it properly –
Place the solar cells onto the wooden board and use the pencil and ruler to draw separating lines carefully. This is an important part of the job and must be done carefully.
4. Wire the solar panel –
After this start soldering the wires to the solar cells and then with each other. First, link the cells in series where the positive lead is to be soldered to the negative lead of the next cell. This has to be kept on doing until you reach a voltage of 12 or 24 volts. No need for more power as it may be dangerous. You need a at least 12 volts to start a 12V inverter to produce 110/220V AC or charge your 12V battery packs. By linking the cell in the series will increase the voltage. Then, stick the cells to the board, carefully. It would be wiser if you made a frame for them where they can be inserted one by one, which will make replacing defective cells very easy. But before putting the cells in their individual places, you have to drill holes to pass the wires, individually. Now make connection buses all along the positive and the negative lead and then connect those buses in parallel (plus to plus, minus to minus) to have a parallel connection and increase the power.
5. Last step –
Now make sure your ammeter bears the solar cells’ nominal power of 108W at 12V means 9 amps. First connect the panel to batteries and then to an inverter. You can also use a computer UPS but you’ll need more power to power your home. The batteries don’t have to be new, and they can be the lead-acid type, but it’s better you buy good ones or else all efforts could go in vain. The idea here is that such a system is cheap and for 200 watts of power you’ll need solar cells worth about $200 and batteries of $400 to $500. If you get an inverter you can set up the whole thing for 500$. Guess what for 1000$ you can light your entire home.
