With continuing price rises on energy, solar panel is coming more to the fore; providing practically free power. It can be expensive to have these installed however, so is a good idea to build your own solar panel.

The first thing is ensure you have the necessary tools and equipment. This will mean sourcing the best solar cells for you, which should be given a good portion of time to decide. There are many out there.

There are a few other items needed. Plywood, a length of 1 x1, copper wire, a diode line, batteries and Plexiglas will be required for construction. You will also need a circular saw, screws and screwdriver, caulk, outdoor paint, soldering kit and glue.

Using your chosen cells as a guide, draw a grid on the plywood. Once satisfied, saw out the entire base and place to one side. It is now time to construct the actual panel itself.

The 1 x 1 will need to be cut into sections depending on the size of the base, and attached using the screws and the caulk. Once all set, this should be painted with the outdoor paint; though not over the grid of course.

Before applying the cells, they need to be soldered together; using tabs at the back to attach one to the other. This work needs to be very careful, as the cells are very delicate at this point. Once in a suitable series, they can be applied with glue onto your plywood grid.

The copper wire should now be attached from the cell to the electrical system and batteries. To ensure no power is lost in the opposite direction, a diode line will also need to be attached at this point.

Finally, a suitable sized piece of Plexiglas should be attached with caulk. This will ensure it is weatherproofed, and cannot be damaged by debris and the like. Having learned to build your own solar panel, perhaps you’ll make enough power to sell back to the grid?

By learning how to make a solar panel you can save money, help the environment, and generate electricity using free energy from the sun with DIY solar panels.
