How to Improve the Quality of Your DIY Solar Panels

If you want to improve the quality of your DIY solar panels, this may be the most important article you’ll read. Because you’ll discover tips on how to push your solar panel system up one notch, you’ll end up with a world-class DIY project.

Of course I’m assuming that resources like money, time and skills are not lacking. On the other hand you won’t have to “sell your barn” in order to implement these tips.

The Solar Panel Frame

Aluminum is one of the best materials to use for your solar frame. Aluminum will not rust easily. It is also able to conduct heat away from inside the solar panel. This is particularly important since heat can lower the efficiency of the solar cells.


There are many different types of diodes to choose from. What you should be using is the Rectifier Diodes & Schottky Diodes. This type of diode has a lower forward voltage drop. This means that less power is wasted. When the temperature gets higher the forward voltage drops further — which is good.

Solar Panel Cover

Instead of using ordinary glass or plastic that can get scratched easily, non-reflective glass helps to improve the solar panel’s efficiency and maintainability. This is because larger proportions of sunlight eventually reach the solar cells when non-reflective glass is used. However you have to make sure that there is no hail at your area before using glass as cover.


If you place your battery outdoor, it enjoys the advantage of being near to your outdoor appliances without lengths of wire running in and out of the house. However it must be sheltered from precipitation, dew and moisture. Otherwise metallic parts will rust easily and your battery might lose its charge rapidly. In the worst case, a short circuit might occur.

To prevent this, you can simply put the battery (or batteries) into a waterproofed electronics housing. Then install a waterproof cable penetrator for the wires to run out to the solar panel and your outdoor appliance. In this way rain or dew will not cause short circuit to the battery.

By implementing Rectifier Diodes & Schottky Diodes to your solar generator project, you can surely make for yourself a world-class DIY solar panel to power your electrical appliance.
