Solar Energy Explained: How Do Solar Panels Work?

Thinking of working toward a cleaner future with renewable energy solutions generated from solar panels, but aren’t exactly sure how it works?

At Solar Naturally, we’re passionate about keeping our environment safe and investing in the future. By harnessing the sun’s energy and transforming it into electricity, we are able to provide clean power that can then be used in your home, business and community.


How do solar panels actually work?

Simply put, solar panels capture ultraviolet rays from the sun and generate a DC of energy which is then converted to an AC.


The sunlight’s ultraviolet rays, or photons, hit the solar panel causing a reaction inside the solar cell, a device which the energy of the UV is converted into electricity, producing a direct current of electricity. The flow of solar energy circuits through the inverter is to then be converted to an alternating current of electricity, which can then be provided to appliances and equipment around your home or business.

This method of renewable energy reduces the need for the generation of fossil fuel and cuts greenhouse emissions. The production and manufacturing of solar panels hasn’t changed much in the last 50 years, because of this, the demand of installations in consumers’ homes has allowed a decrease in cost of solar cells.


What about excess energy from solar panels?

Excess energy can be sent to a battery storage system where it can be reserved for later use, regardless if the sun is shining or not.

It can also be sent back to the grid, taking in unused energy generated by the solar panel system. If the sun’s hiding behind the clouds and the stored power is needed, the switch between the solar panel system and the grid is automatically shifted to allow power to be drawn from the excess.

Unused energy can also be credited to your power bill where the amount is determined by the feed-in tariff. In order for the units of incoming and outgoing power to be reported, a new bi-directional meter must be installed by your electricity retailer.

By mounting solar panels onto the roof of your home and maximising the exposure of sunlight, this energy system is bound to help reduce your carbon footprint as well as your power bill, as you create your own energy to use and save.
