Components Of A Solar Panel Syste

The most important component of a solar inverter system is the solar panels themselves. These are photovoltaic cells made from silicon crystalline wafers (similar to the semiconductors used in computers) that convert sunlight into electricity. There are two different types of silicon based solar panels, polycrystalline (poly) and monocrystalline. Mono crystalline solar panels are made using the more expensive single-crystal Czochralski process while poly panels use multiple silicon fragments blended together to make the cells. Historically, mono panels have offered better energy production but improved manufacturing processes and lower costs are bringing the efficiency of poly and mono cells right up to par.

Sun-Powered Savings: A Guide to Financing Options for Installing Solar Panels

Solar panels are connected in series and parallel to achieve the desired voltage and current capabilities of a solar power system. Blocking diodes are incorporated in the solar panels to prevent back current flow that occurs when modules are shaded and bypass diodes are inserted between modules to allow current to pass through un-shaded modules that would otherwise significantly limit module output.

A battery storage system is an optional addition to your PV system that allows you to store excess energy for later use. It can also provide backup power during outages.

The next most important component is the racking/mounting system which is what securely attaches your solar panels to your roof. A good quality racking system should be able to handle wind loading and be ideally positioned to maximise your sun exposure. Make sure you choose a reputable installer that uses quality equipment from brands like Radiant and Sunlock, Australian made, to ensure the longevity of your installation.
