Solar energy is radiant light and heat from the sun that are harnessed using a range of technologies.

Solar photovoltaics (PV), which use energy from the sun, are one of the most popular energy solutions for off-grid buildings. PV arrays (solar panels) allow for energy from the sun to be converted into electrical energy. PV is dependent on solar radiation and ambient temperature. Other components needed in a PV system include charge controllers, inverters, and rapid shutdown controls.

Advantages of solar fuel production through artificial photosynthesis include: solar energy can be immediately converted and stored. Solar panels have no moving parts. They are part of a completely stationary system. So once they're installed, there's not a whole lot that can go wrong. Pretty much the only thing a homeowner needs to do is keep the panels clean.
