How to Build Solar Panel — What Materials Do You Need To Build A Solar Power Generator? by John GreenspanIf you want to learn how to build a solar panel, the first (and most important) step is in knowing the materials and components required. The materials listed below are meant for a particular class of solar panels — one that’s capable of supplying appliances like your garden sprinkler or automatic gate opener with electricity.Now, let’s see the list of materials we need:Solar CellsYou have two options — to buy new solar cells or salvage used ones. Obviously it’ll be more costly to buy new solar cells. If you are not willing to splurge, used solar cells will be fine…and you can even get broken solar cells and join them together. But if you’re not comfortable doing this, it will be less frustrating to work with new solar cells instead.PlywoodYou’ll need three-eighth inch thick plywood and these are easily available in your local hardware store. Art supplies shops may sometimes carry good-quality plywood frames that can be used for your project.Jones PlugA 2-pin Jones plug is necessary to connect your solar panel to the rest of the solar powered circuit. This enables the solar panel to be detached easily for maintenance when necessary.Silicone CaulkThis is a waterproof seal that is commonly used for fixing bathtubs and kitchen sink.Super glue and screwsSome super glue (or wood glue) is needed to hold the pieces together before you turn the screws in. Wood glue will take much longer to dry, so super glue is recommended.WiresThe best types of wire for a solar panel are those that come as a twisted pair of red and black. Chances of mixing up their polarity reduce dramatically with these types of wire.PaintSince the solar panel is placed outdoor, it is necessary to protect the wood from elements such as precipitation, dew and moisture.DiodeThe diode ensures that electricity only flows from the solar panel into the battery, never in the opposite direction. This is to make sure that the battery is not discharged into the solar panel during the night.PlexiglassThis is a protective cover over the solar cells. Plexiglass is often preferred over glass because it doesn’t break easily and is easier to handle.BatteryHaving a battery ensures that your appliance continues to run even at night or on very cloudy days.The above are the components you need to put together a solar power system that can supply electricity to a small appliance. When you have accumulated more experience, you can substitute these materials for better ones. As for now, these the easiest materials to work with.John Greenspan is a recognized expert in do it yourself solar panels and has build several solar power generators in his spare time.
