5 kW Solar System Perth – More Value for Money than a 3 kW system?

The answer is relatively simple. In Perth, a 3kW, though sufficient for most homes with an average bi-monthly bill of around $250, is NOT future proof!

First of all, after a couple of years, let us assume that you have to upgrade your rooftop system to meet your growing electricity consumption. Then, you will incur an extra 2000-3000$ for upgrading your 3kW inverter, which will stretch your payback period by another 3 years.

Second, considering the fact that price of solar batteries is falling like a meteor, every household will be able to afford them within the next 1-2 years. So, if you opt to install a solar battery down the lane, then a 3kW system will not be able generate the excess energy that your battery can store; this leads to an underperforming battery installation.

So, in conclusion: a 5kW system will be able to ensure that your home is ready for battery pack, while meeting your future electricity consumption growth. As a result  your solar system payback period shortens over the next 6-9 years.
