How To Build Solar Panel (Part 3 of 3)

In this final part of the “How To Build Solar Panel” series, we’ll impart the finishing touches that make your solar panel project a winner. You’ll discover how to push your solar panel system up one notch so you’ll have a world-class DIY solar panel.

Here, I’m assuming that resources like money, time and skills are not lacking. What we’re trying to push for is a solar panel that will make you proud.

The Solar Panel Frame

The best material to use for the solar panel frame is aluminum. This is a material that will not rust easily and it’s able to carry away additional heat that may be trapped inside the solar panel. This is particularly important since heat can diminish the efficiency of the photovoltaic cells.

Diodes

The diodes you should be using are the Schottky types. These diodes have a much lower forward voltage drop so less power is wasted. And when the temperature gets higher the forward voltage drops further.

Solar Panel Cover

If budget allows and there is no hail at your area, the best cover that your solar panel can have is made of non-reflective glass. Solar panels covered with non-reflective glass can enjoy significantly higher efficiency because greater proportions of sunlight reach the solar cells.

Battery

If you intend to power outdoor equipment like sprinklers and gate openers, your battery will need to be sheltered from the rain and dew. Unfortunately it may be impractical to house these indoors as we’ll then need very long wires that may also be a safety hazard if it’s left lying around.

You can put the battery (or batteries) into a waterproofed electronics housing and seal up the opening (for the wires). In this way rain or dew will not cause short circuit to the battery.

By implementing all of the above tips to your solar panel project, you can surely make for yourself a world-class DIY solar panel project.
