Solar electric panels (or photovoltaic/PV modules) are devices that convert sunlight energy into electricity, but how do you know which one to choose and what are the differences between them?
All inverters convert direct current (DC) electricity into alternating current (AC) electricity, but that's where the similarities end between inverters. These days, a huge number of brands and options are available to consumers, and the correct choice for you depends on how you intend to use it.
Learn why you need an inverter in your renewable energy system, the different optional features that they offer, and the advantages/disadvantages of different inverter types.

Solar charge controllers are an essential element to any solar electric panel system. At a most basic level, charge controllers prevent batteries from being overcharged and prevent the batteries from discharging through the solar panel array at night.
Maximum Power Point Tracking (MPPT) is a popular technology that an increasing number of solar charge controllers offer. While MPPT charge controllers usually cost more than traditional solar charge controllers, the gain in overall charging efficiency makes them well worth it in most cases.
Solar panel arrays can be mounted in many ways, so it's important to understand considerations like materials, costs, and orientation before deciding on a mounting system.
