Frequently Q&A

How solar energy system does work?

Solar power works by converting light from the sun into electricity. This electricity can then be used in your home or exported to the grid when you don’t as much as it converts. This is done by installing Solar Panels on your roof which generate DC (Direct Current) electricity. This is then fed into your inverter which converts the DC electricity from your solar panels into AC (Alternating Current) electricity.

Your solar cells produce electricity via the photovoltaic effect, where sunlight creates electricity in certain materials by knocking their outer electrons loose.

The DC electricity generated by your solar panels is directed to your central inverter (or micro inverter, depending on your system set up), where it is converted into AC electricity your home and appliances can use.

Your inverter will ensure your home always uses your own solar production first, only accessing additional energy from the grid when your own supply is not enough. Any solar energy you don’t use will be exported the grid for a nominated feed-in tariff.

Your electricity retailer will install a new bi–directional meter which will monitor and report both the incoming and outgoing electricity.

Your electricity bills will then take into account the lower amounts of electricity you will need to buy from the grid plus credits for the electricity generated by your solar power system that you don’t use.

With solar power, you don’t need to switch it on in the morning or switch it off at night – the system will do this seamlessly and automatically. You don’t need to switch between solar power and the grid  – the system does this all automatically so you won’t notice any change to how the appliances in your home function. In fact a solar system requires very little maintenance (as there are no moving parts) which means you’ll hardly know it’s there. This also means a good quality solar power system will last a long time.

Your solar inverter (usually installed in your garage or in an accessible spot), can provide you with information like the amount of electricity being produced at any particular point in time or how much it has generated for the day or in total since it has been operating. Many quality inverters feature wired or wireless connectivity and sophisticated on-line monitoring and reporting.

Why solar energy?

The main advantage is that it is a renewable, clean source of electricity. Solar power is also scalable. This means that it can be deployed on an industrial scale, or it can be used to power a single household. When it’s used on a small scale, extra electricity can be stored in a battery or fed back into the electricity grid. Overall, the sun gives off far more energy than we’ll ever need. The only limitation is our ability to convert it to electricity in a cost-effective way.

Will winter or cloudy weather affect solar power?

Temperature does not affect the efficiency of solar power generation, because PV systems get energy from solar light instead of temperature.
Solar PV system can also generate electricity on cloudy days, but the efficiency will be impacted by the sunlight decreasing.
When the solar system cannot meet the load demand or does not work because of cloudy days, the electricity from the power grid will actively make up for it.

How much panel capacity do I need?

Nowadays you don't make much money from feeding electricity back into the grid. So you need to maximise your own use of your solar PV and minimise your export into the grid.

The panel capacity depends on your roof space and your current electricity usage.

At Say Yes Solar, we will design a system that will suit your needs.

How can I get government rebate

The Australian government will give you a rebate on the purchase of solar panels. The solar panel rebate varies depending on where you live, the system size you install and on market prices, but typically, the incentive will save you between $2,500 – $3,300 off the price of a 6.6kW solar system.

Claiming your solar panel rebate from the government is typically straight-forward. However, there are a few things you need to do to ensure you receive your buying incentive.

  • Panels must be approved by the CEC
  • Your installer must be CEC accredited
  • You must claim your rebate within 12 months of installation

Say Yes Solar as a CEC-certified solar retailer, when you contract with us, we will do all jobs for you and our quotation is the price after rebate.
