Photovoltaic technology uses semiconductors to produce power based on the photoelectric effect. If photons of light (either natural or artificial) with enough energy penetrate a photovoltaic cell, they can excite electrons to a higher energy state. In fact, the electrons of a semiconductor that are not normally free, will become free and act just like they’re in a conducting material. …

Solar energy takes light from the sun and turns it into free electricity. But shade from nearby trees, roofs, or buildings can dramatically reduce the amount of electricity your solar system produces, even on sunny days.  Does a Solar Panel Need Direct Sunlight? Solar panels need constant and direct access to sunlight to maximize their electricity production. However, whether due to shading …
