Solar Panel Installation FAQ

How many solar panels are needed to power a home?

You may be limited by not only your budget, but also by how many panels can fit that will receive enough sun. For many homes, the secret number is 6.6kW of panels, which equals about 22 to 24 in total. This combines with a 5kW inverter to supply the power you need.

The biggest mistake homeowners make is not installing enough panels. Adding the panels later is more expensive than doing it up front, so make sure you have the system you want at the beginning.

Can you buy and install your own solar panels?

It is possible to buy and install the solar panels yourself, but it’s is not recommended. Having a solar panel installation expert is a better option, especially if you aren’t well-versed on the subject. These technicians have the experience needed to tackle your job with ease.

When choosing someone to install your solar panels, make sure they are licenced. While it is tempting to have an untrained person work on the system in order to save money, it’s simply a disaster waiting to happen.

How much does it cost to install solar panels in Australia?

5kW worth of average panels will run around $2,500. A higher quality 3kW system runs between $5,000 to $8,000 simply because of the upgraded materials. With that in mind, it’s easy to see that there is a wide range of price points, depending upon the system you choose.

Do you really save money by installing solar panels?

Electricity prices continue to rise, which is leading to an increase in consumers looking at solar power. The great thing is that solar costs are at a record low. A 5kW system can generate around 20 kWh per day. If you pay 30¢ per kWh, you will save $2,000 each year on the power bills.

With today’s costs for the parts and installation, you are looking at a return on investment within three to five years. The extra benefit is that you are no longer dependant on the increased cost of electricity. Who knows how much that will cost in the future?
