Q: How do Solar Photovoltaic (PV) panels function?

Solar panels utilize layers of unique materials known as semiconductors and generate electricity when exposed to sufficient sunlight. There are various types of solar panel construction. Some perform better in low light and high temperatures but consume almost twice the space.

Q: Can I get financially better when I switch to solar power systems?

Typically going solar can help you save energy and lessen electricity bills. A solar power system will typically reduce the amount of power that you buy from the grid and through the feed-in tariff, you receive for excess power that one sells to the grid. 

Hence, you will be better off using a solar power system. However, this does not mean that you will never pay electricity bills ever again. Also, it helps to note that the amount of electricity will depend on your electricity usage, the size of the system, and whether the solar system is in the ideal location.

Q: How long will a solar power system pay for itself (return on investment)?

The time needed to get a return on investment will hugely depend on the price received as a feed-in tariff from the energy retailer. Other factors that will determine your payback period include your consumption patterns, system size, and initial investment.

Generally, the investment return can be less than three years for those that receive the premium feed-in tariff and use small amounts of electricity. However, the payback period will be around seven years if you consume a lot of electricity and are not eligible for a premium feed-in tariff.

Q: How much electricity will the system generate?

The amount of electricity that you will generate depends on the system’s size, climatic conditions, and the location that the system is facing. Of course, your system will not generate a lot of electricity when placed near buildings or shaded by trees. 

Q: How much will I get for the electricity generated by my solar system?

Your electricity retailer will pay you for electricity that you export to the grid. It, therefore, helps to check and compare the feed-in tariff offered by different electricity retailers.

Q: Is the solar PV system prone to corrosion?

Provided the electrical components are manufactured with top-calibre quality, inverters can withstand all weather conditions. The mounting system and frames offered by EU Solar are made with anodized aluminium and are covered in an anti-corrosive agent. Inverters are designed for exposure to the environment. 

Q: Does the solar power system need regular maintenance?

In most cases, your system will need very minimal maintenance as long as it is designed using quality components. Following a maintenance schedule will prolong the life of your unit. Also, the surface of the solar panels is self-cleaning, but it depends on the degree of pitch. 

Q: How does the solar rebate work?

A solar rebate scheme known as the Small-scale Renewable Energy Scheme (SRES) gives you tradable certificates known as the small-scale technology certificate (STC). These are often offered as an upfront discount on the solar system, with the installer trading the certificates on your behalf. It is one of the federal government’s financial incentives for those who switch to solar.
