How to Make a Solar Power Generator for Less Than $300

Posted on 08 December 2009

It is now possible to make a small solar power generator for $250 to $300, by using parts that are easily available from the internet or your local stores.

Whether you live in a far off area, outside the range of the grid, or you just want to make your own electricity, it can be a great idea to save up on your bills.

You can supply power to your computer, modem, vcr, tv, cameras, lights, or DC appliances.

Here are some easy steps to follow in order to make a solar power generator:

1. First of all, you will need to buy or make a small solar panel. You can get it for about $100, to support12 volts or 16 volts.

2. Buy a battery. It is recommended that you go for rechargeable batteries from green companies that supply online, or you can get it from a store as well. Get a deep cycle, 12 volt, lead/acid or gel battery. You will need the deep cycle battery for continuous use. The type of battery in your car is a cranking battery–just for starting an engine. Look for sales, the cheapest ones should cost about $50-60

3. Find a battery box to put it in. You can get it for $10. If you plan to install the system in a pump shed, cabin, or boat, then skip this.

3. Buy a 12 volt DC meter. It is possible to get one for $25.

4. Buy a DC input. The triple inlet model is preferable and can be found at a car parts store in the cigarette lighter parts section for about $10. This should be enough to power DC appliances.

5. In case you want to run AC appliances, you will have to go for an inverter. This will convert the stored DC power in the battery into AC power for most of your household appliances. Calculate the number of watts you’ll be using e.g., a small color television usually takes 60 watts with a VCR of 22 watts, so together you’ll need 82 watts.

6. Attach the meter and DC input to the top of the box with the help of a drill.

7. By using insulated wire, attach the meter to the wingnut terminals on the battery. Connect the negative (-) pole first. Only handle one wire at a time. Connect the DC inlet to the battery in the same way. Then, connect the solar panel to the battery in the same way.

8. Close the lid and tie a cord to keep it tight. Put the solar panel in the sun. It takes about 5 to 8 hours to charge a dead battery, and 1 to 3 hours to top off a weak one.

This battery will be able to run radios, fans, and small wattage lights all night, or give you about 5 hours of continuous use at 115 volt AC, or about an hour boiling water. This system may be added on to with larger panels, inverters, and batteries.
