How a Photovoltaic System Produces Electricity

How a Photovoltaic System Operates As described in The Beginner's Guide to Solar Energy, solar panels convert the energy of photons into electricity. This process is called the photovoltaic effect. When a photon hits a photovoltaic device, its energy is transferred from the photon to the local electrons in the material. These excited elec…

How to Size a PV System from an Electricity Bill

Sizing a PV System from an Electricity Bill An electricity bill typically reveals information about a residential or commercial customer’s total monthly energy consumption. From this value alone, it is possible to approximate the required size of a PV system that offsets monthly energy usage. Take a hypothetical monthly energy consumpt…

Shade Losses in PV Systems, and Techniques to Mitigate Them

Effects of Shade on PV Output Since PV systems generate electricity based on the amount of sunlight they receive, it makes sense that when a shadow is cast on a panel, for example by a nearby tree, its power output decreases. However, the decrease in power could be a lot worse than it initially seems. Figure 1. Solar panels in partial sh…
