Why does a 5 kW Inverter go with a 6.6 kW Solar System?

A 5 kW Inverter can manage up to 133% of its power capacity, it is advisable to make the most of it; hence, 6.6 kW panels are fitted with a 5 kW Inverter.

Furthermore, due to the position & orientation of the installed solar panels and the roof’s pitch, there would also be energy loss from the panels to the inverter so 5 kW of panels typically produces for a 5 kW Inverter to be maximum efficient. As a result, it is strongly recommended that more panels be installed for the power of the solar inverter.

What is the payback period for a 6.6 kW solar system?

Usually, the payback period for a 6.6 kW solar system is about 3 to 4 years, making it competitive with many other forms of renewable energy.

Many factors affect the payback period, such as location, the roof’s pitch, the panel’s orientation, system size, energy use, panel efficiency, and of course Consuming habits of the customers.

For instance, if your roof receives a lot of shade, you will require additional panels to produce enough electricity to cover up for the output loss. However, if you live in an area where it gets lots of sunshine, you might require a smaller system to reduce your electricity expenses.

Another essential factor that can affect your payback period is consumption habits during the day. With more usage during the day, more money will be saved, then of course fewer years for Return on Investment

Another crucial aspect that can affect a solar system’s payback period is panel efficiency. Panel efficiency refers to how effective a solar panel is at converting sunlight into electricity. Generally speaking, higher panel efficiencies result in shorter payback periods for solar systems because they produce more electricity than lower-efficiency systems.
