There are five renewable sources and these are solar, wind, geothermal, water, and biomass. Solar energy is the energy received from the sun. Solar panel using renewable energy from the sun is an array of photovoltaic (PV) cells. Solar cells are arranged in a grid-like pattern on the surface of solar panel. Solar panels have mostly been used as stand-alone systems for energy. These systems are being deployed throughout the industrialized and developing world on a commercial scale. PV modules are typically installed on aluminum or galvanized, painted, or stainless-steel frame structures. Stainless-steel grounding components in solar panels are often pressed into the base aluminum, which is creating a dissimilar metals connection, where galvanic corrosion may develop in the presence of electrolyte. Aggressive ammonium hydroxide develops in livestock barns, which may lead to corrosion on solar panels.
