Most people know that solar energy works by using the power of the sun. But you might not know so much about the intricacies of how solar power actually works.
How Solar Panels Work
The solar energy production process begins with the installation of photovoltaic panels (solar panels) on your roof. These are usually mounted on a slope directly facing the sun. We position them to produce best results. The number we use depends on the size of your roof and the amount of energy you are hoping to produce.
Once we have installed the panels, we connect them via cabling to an inverter at your property. Which, in turn, we connect to your home wiring system. The solar panels, which are made of a conducting material like silicon, harness power from the sun’s rays even on cloudy days, albeit to a lesser extent to create electricity.
The panels convert radiance to Direct Current (DC) power. This power travels to the inverter. Then the inverter converts the power to Alternating Current (AC). You can use this power in your home for anything you would normally use electricity. For example for lights, appliances and heating and the solar power will be used instead of your standard grid electricity.
You may choose to add batteries to your system. The batteries store electricity for night time use. We can talk you further through this option during your consultation process.
If you choose to use solar energy, we will also need to fit an import/export meter at your property. This will measure how much electricity you are using from the grid during the times you rely on conventional electricity. The meter will also record how much if any, the surplus electricity you are giving back to the grid. You will have surplus electricity if your solar output exceeds your usage needs. Most power companies will pay you an agreed amount for any excess electricity you provide.
Maintenance of your Solar Panels
After we have installed your solar energy system, it needs very little maintenance over the years. There are only a few parts to the solar power system. You will need to clean your panels at least once a year to remove any layers of dirt that may impede sunlight collection. Also, ensure that any nearby trees are kept trimmed to make sure they are not casting shadows over your panels.
Thinking of Moving to Solar Energy?
If you think that switching to solar power could benefit your business, or you are considering using solar energy to power your residential property for some of the time, then a consultation with us can help you work out the best size of the system for you. We are NZ registered electricians and ensure our installations are done with the highest quality workmanship and to all NZ standards.
