Solar panel electricity system, which is also known technically as photovoltaic (PV) panels, function by capturing the sun’s energy and converting it to electricity. The advantage of PV cells is that these don’t required direct sunlight, but can also work to an extent during cloudy days too. Installing PV panels at home can help you get the needed power to light up your home and run the appliances. Many people in Australia depend largely on solar power lately.
Benefits of solar power
- Cut your electricity bills – Sun can give you free energy for long once if you make an initial investment for installation of solar panels.
- Get paid for the extra electricity you make – The government has now announced an Feed-in Tariff Plan with which you can get paid for the electricity you produce in surplus to upload onto the grid.
- Reduce your carbon footprint – Solar power is a green energy resource and doesn’t produce any harmful gases or pollutants. A home PV panel may save over 30 tonnes of carbon dioxide production over its lifetime.
How do PV solar cells work?
These types of solar cells are made of various layers of semiconductor materials. Usually high quality silicon is used as the semiconductor. PV cells can create electricity field when light falls directly on them. The stronger sun’s light is, the more electricity will be produced. In typical quality Port Lincoln solar panels for home mounting, PV cells will be stacked in modules of various sizes based on the output requirements. Power of photovoltaic cells are measured as ‘KWp’ (kilowatts peak), which is the measure showing its production capacity during full sunlight days in summer.
Solar panel installation cost
Various factors affecting solar panel cost are;
- The more electricity PV panels can generate, more the price would be. However, it also implies it can save more for you overtime.
- Larger systems (more than 4kWp) are deemed to be more cost-effective than the smaller systems.
- The PV panels are almost of the same price per kWp, but the PV tiles may cost more than panel systems.
- The built-in panels on roof are expensive than the sit-on-top roof mounting panels.
- There are many government subsidies also on solar panels. However, to avail this, you need to ensure that you purchase the panels from an authorised dealer and take care of all quality standards to claim the subsidy.
Maintenance of solar panels
The PV panels demand only less maintenance. You have to just take care of cleaning the panels once in a while and also ensure trees or other structures don’t shadow them. Debris accumulation is easier with ground mounted solar panels, so you need to do cleaning regularly.
The installer may give you written instructions about the maintenance and timely check‑ups to be done in order to ensure the good health of your solar panels. It is not just the panels, but the solar system consists of inverter, battery, custom wiring etc., which all needed to be maintained properly for maximum output. A good solar panel may last for more than 25 years, but the inverter may require replacement after a particular time period.
