A solar panels system is a collection of photovoltaic (PV) cells that convert sunlight into electricity. They are made from semi-conductive materials, most commonly silicon.
There are many different types of solar panels system, which vary in efficiency, durability, reliability and output. These factors are important to consider as they affect your solar energy production and potential savings.
Panels are constructed from one of three main types of solar cells: monocrystalline, polycrystalline or amorphous silicon. The most efficient type of solar cell is monocrystalline, which can be manufactured in a variety of shapes, sizes and styles.
The next type of solar cell is polycrystalline, which is more common and less expensive than monocrystalline panels. The third type of solar cell is amorphous, which can be flexible and is the least efficient.

Inverters are a critical part of a solar panel system. There are a number of types, including central inverters, microinverters and power optimizers.
Central inverters – A single inverter per array that connects to all the PV modules, producing AC power. These inverters can be fixed or mobile, depending on your preferences.
Power optimizeers – Installed in each individual PV module, these inverters allow the DC output of each module to be optimized before being sent to the central inverter. This allows the overall system to be more tolerant to shading and improves the ability to add additional PV modules in the future without having to modify the existing central inverter.
