How to Build Your Own Solar Panel at Home

November 3, 2009 by  

If you want to build your own solar panel at home, it can get pretty expensive buying everything from a retailer. However, you can cut costs if you decide to make a solar panel at home with the parts I will mention below. It’s a lot easier than it sounds, and as an added benefit you can take your homemade solar panel with you anywhere you go.

Making a Solar Panel Using Basic Parts

A basic solar panel will cost you anywhere between $250 and $300. You can find the required material at the hardware store or even online. The first thing you’ll need is a solar panel that is rated at 16 volts.

Homemade solar panelsYou’ll also require a battery – it is best to look for rechargeable batteries. A size deep cycle 12 volt lead/acid or gel battery is ideal when you’re building solar panels. You can’t use a car battery for this.

You’ll want to purchase a battery case as well. This will protect the terminals. It also makes things safer for when children are nearby.

Shop around for a 12 volt DC meter and a DC input. Both are pretty cheap and easy to find. If you intend on powering AC appliances, then you will also need an inverter. Although they can be a bit expensive, you can still find some cheap ones.

You can start building a solar panel by fixing the meter and the input on top of the battery box with a drill. You need to attach the battery to the DC input. Use insulated wire and start with the negative pole on the battery.

Next, you should connect the solar panel to the battery and close the battery box. You now have a working solar panel!

All you have to do now is charge the battery. Place the solar panel in the sun and wait until the battery charges up before you start using it. It’ll take about 6 or 7 hours before the battery can be used to power up your appliances.
