How to Build a Solar Panel

Solar energy has provided a new source of renewable energy from one of the most convenient sources – the sun! Fortunately, for many homeowners, products that use these devices have allowed them to save money on many devices around the home such as lighting and other small appliances that are used outdoors. Additionally, large solar panels have allowed homes to go ‘off the grid’ and provide their own power from the sun, lowering their monthly bills for electricity and achieving a minor level of independence. Such installations, usually large panels installed on rooftops, heavily reduce one’s carbon footprint and environmental impact and so for many people, these devices have become a lifesaver in making the world a healthier place.

In that same spirit of independence and the desire of many homeowners to do it themselves, many people have begun different projects to build their solar panels themselves. This reduces the cost and hassles of installation, such as finding a company and purchasing or renting the panels, and allows a homeowner to repair the panels themselves. Building a solar panel is an intensive project that should not be undergone lightly, but fortunately the materials involved are not especially dangerous and the rewards that are reaped are huge comparatively. Here are the basics of how to build a solar panel to help homeowners get started on this very rewarding project.

Solar panels are actually quite simple in theory and so many people can access their technology with just a little work. Any solar panel produces electricity through the use of photovoltaic cells. These cells are sensitive to light and produce electricity when certain wavelengths of light strike their surface. These cells are very brittle and damage especially easy, so they must be housed in a strong and sturdy construction that is also resistant to moisture.

Now many types of material are sensitive to sunlight and will produce electricity, but the real name of the game when it comes to making a true solar panel is efficiency. The types of cells used in the construction of these devices have different levels of sensitivity to the types of sunlight that will produce electricity and how much electricity they will produce when struck by sunlight. For less efficient models, more panels are needed to power a home and vice versa. Many people have made cells out of household material and each person undergoing such a project will have to judge themselves on whether using a given photovoltaic medium is worth the cost and the space.
