Solar panels are made of highly excitable, conductive materials. When the sun’s rays hit the solar panels, the reaction creates direct current (DC) electricity.
Since most homes and businesses use alternating current (AC) electricity, your solar-generated DC energy will pass through an inverter to become AC electricity. Then it flows through your property’s wiring and behaves just like the power you’ve been using your whole life.
The only time your solar panels stop generating electricity is when the sun’s not out. That means at night and during eclipses.
The sun is constant and reliable. Determining the right size solar power system is based on your actual usage of power. Greener Housing Solutions can work this out for you.
In a South Australia you need to sell appropriately 2.5 kw’s of solar generation to earn 1 free kw at night. Battery backup makes sense as it is Kw for Kw. However there are times that we will advise that Battery Backup may not be for you but this will be discussed once we have more information on what your usage is, your ability to feed a battery backup system etc. Battery backup also gives you the opportunity to keep your lights on when the grid (SAPN) goes down eg load shedding, scheduled SAPN outages etc.
This depends on your roof space and Whether your single phase, dual phase or 3 phase property.
- Only 5kW of inverters are allowed on a single phase supply
- You can export limit a bigger inverter (up to 10kW)
- SAPN doesn’t say you can’t oversize the inverter’s nameplate capacity by 33% as is normal
- With single phase supply you can AC couple a battery as long as the total inverter capacity is less than 10kW and the system as a whole is export limited to 5kW
- 3 phase homes can fill their boots with 30kW of inverters and 40kW of panels.
