Learn how solar works and how to get the most from your solar system:

The first thing to know is that solar panels rely on light from the sun. 

Solar panels work by converting sunlight into DC electricity. When photons from sunlight are absorbed by the connected silicon cells in a solar panel, electrons are released. As these electrons flow (current) through the panel circuit, electricty is created in the process. This process of converting light energy (photons) to electricity (volts) is called the Photovoltaic effect.

The electrons flow through the solar panel and string (which in traditional set-ups connect each of the panels on your roof) eventually making their way to the solar inverter.

It’s the inverters job to convert the DC power from the panels into AC electricity, which can then be used for your home. Your inverter also changes the voltage from the panels to match the voltage in your house (which is around 240V).

How solar works

Solar Power

In most cases excess power created by your solar system is fed back into the grid, meaning your power supplier may credit you the next time your bill arrives. However, more and more homes are investing in Solar Battery Systems. These battery systems allow additional power to be stored for later use.

Solar Cell Efficiency

Advanced panels and the right condition lead to the best solar cell efficiency.

Without getting too scientific, here are a few things you can do to maximise the efficiency of your solar system:

  • Solar Panel Positioning – Solar cells are most effective when they are placed in a position of direct and constant sunlight.  Shading, whether from trees or simply clouds passing by, will affect the efficiency of the cells.  Therefore, north facing, tilted, unshaded panels are the most efficient.
  • Solar Panel Maintenance – Cleaning and regular maintenance will keep your solar panels free from dirt and grime, helping to increase efficiency.


Best Solar Panels

Most manufacturers have an output tolerance of - /+ 3%. That means that they perform within 3% of the expected Watts output. Check the tolerance and type of panel you buy.  Most panels are silicon crystalline solar cells, however, better panels will have a solid copper backing, thicker connectors and no grid lines in front of the cells.  Better panels convert more power and last longer.

Solar panels are affected by heat.  The hotter they get the less efficient they become. Therefore it is important to check that the panels you have selected have been tested for real world conditions. All Termico Solar panels are suitable for use in Perth weather conditions and to ensure panel quality, we only provide panels from Tier 1 manufactures.
