Frequently asked questions

How do solar panels work?

Solar panels are solid- state devices which are made from thin layers of semiconducting materials, mostly silicon to form solar cells. When exposed to light the solar cells generate electrical chargers which produce electricity. Several cells are placed together and covered by glass to form a panel, as a single cell alone does not generate a lot of electricity. The solar panels are then placed together on a surface where optimal light from the sun can be absorbed. Solar panels are low maintenance and are reliable pieces of equipment as they have fixed parts which do not require movement. The solar energy system does not produce any gas and there is no noise generated from this process, which makes the solar energy system an environmentally friendly energy production.

What are the environmental benefits of solar?

Solar energy provides significant environmental benefits when compared to traditional fossil fueled power stations, such as coal. Coal is detrimental to the environment and releases toxic substances into our air and water, such as nitrogen dioxide, sulphur dioxide and mercury. However, solar energy is produced purely from the sun resulting in no CO2 emissions. It has a domino effect that reduces the reliance on coal, which reduces our carbon footprint and helps mitigate climate change. Solar energy also saves thousands of litres of water as opposed to conventional power stations’ high water usage.

How many solar panels are needed to provide sufficient electricity for my property of business?

The number of panels installed is based upon factors such as; the structure and size of the roof or mounting system, the required amount of energy, and the orientation and location of the roof. Each roof is unique regarding these factors mentioned, therefore, the number of panels will vary. Solar panels come in wattages ranging between 150 watts to 370 watts per panel. (See Average kWh solar panels.). The number of solar panels is not an accurate determination of how much energy a roof can obtain, but rather the amount of wattage of each panel and the required energy consumption.

Will I be able to go fully off-grid?

Your business will still be connected to the electricity grid, but whenever the sun is shining or you have energy stored, you will only be using your own solar power. During power outages or load shedding, you will be self-sufficient for hours and won’t need to fall-back on a polluting, noisy diesel generator.
