5 kW Solar System Perth – Market Condition
The solar system prices in Perth is one of the lowest in the country. As per SolarChoice, for the month of March 2017, the average price of a 5 kW solar system in Perth is $4,845. This factor, combined with the feed-in tariff of 7 cents/unit makes the purchase of such a system, by default, financially beneficial.
But the selection of solar power system is not always so simple. With the drop in solar power system prices, only 1000$ separates a 3kW and 5kW solar systems. Therefore – “Is it worthwhile to spend a little extra and choose the 5kW system?”, this becomes the obvious final question to a prospective buyer.
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.
