Depending on several factors, the actual power output of a 6.6kW solar power system will vary and this will contribute to your financial return. These factors include:
Geographical location of the system and the expected daily and annual solar irradiation and cloud cover levels there
Orientation and tilt angle of the solar panel array
Whether there is any shade cast on the panels
Actual operating temperature of the panels
The performance of the individual components (e.g. the panels and the inverter)
Solar Feed-in Tariff schemes
Solar products play a large role in the financial gains of a solar system. For example:
Cheap inverters and solar panels on average will save approximately $1420 per year on your power bill with a payback period of 4 years.
SolarEdge inverter and optimisers and REC solar panels will save approximately $2060 per year with a payback period of 3-4 years. That is a Rate on Investment (ROI) of 448%. Imagine if you invested $100 today and received $300 in return - the ROI would be 200%.
When installing a solar system for your home or business, it's not just about solar, it's about quality products and installation. A SolarEdge and REC solar package may cost more upfront but in the long run, it will save you a lot more on your power bills.
