How Much Could You Save With Solar in Perth

How much can you expect to save with solar panels in Perth and how can you make sure you get the most out of your investment? Did you know that Australia leads the world for having some of the best solar resources? This is due to the fact that it has the highest solar radiation levels per square metre out of anywhere else on the planet. Since Perth sees an average of 147 sunny days and 121 partly sunny days each year, it’s an ideal location for solar power. But, how much can you expect to spend when you install these panels and how long will it take to get a return on the initial cost? We’re going to answer all of these questions and more by the end of this article.

Average Installation Costs

Installation costs dropped around 37 percent in 2017, so there has never been a better time to install your own panels. The total installation costs depend on a few factors, including how powerful of a system you want, where you’re located and the size of the system. However, we have a rough estimate that’ll let you get a good idea of the current costs. The approximate cost of one of these systems in Australia are as follows:
3kW System – $2,000 and $6,000
5kW System – $3,000 and $9,000
10kW System – $6,000 and $18,000
The first thing you have to decide is how large of a system you need to generate the adequate energy levels that you to run everything in your home. You should take a look at your last energy bill to see your average daily and monthly usage. Your energy usage will be listed in kilowatt hours (kWh). To put it in perspective, larger households or properties will usually need around a 5kW setup to support its energy needs. This system can generate between 18 and 25-kilowatt hours of electricity every day. You also want to factor in battery storage if you plan to have it on your system. If you plan to add it, know that it can double or even triple your initial costs. An entry level battery storage setup will cost around $2,000. If you choose a higher end battery storage device, it can cost up upwards of $11,000.

How Quickly Your System Will Pay for Itself

How quickly your system pays for itself depends on how much you save on your electricity bills. This is commonly referred to as the payback period, and it fluctuates depending on how expensive your initial installation and purchase costs are, whether you choose to install a battery or not, and how expensive your electricity is in your area. If you decide against getting a battery setup for your system, you can expect the payback period to last roughly five years. However, since most systems are designed to last 25 years or more, this is a significant payoff. If you decide to include a battery setup for your system, you can expect your average payback period to range around 10 years. This is still a significant payoff.

Getting the Most Out of Your System

You want to do everything you can to make sure that you get the most out of your new system. If you don’t have a battery, your panels will run when they get sunlight, and any excess energy will feed back into your grid. This energy is what your energy provider will give you credit for at the end of each month to offset your power costs. Anything your panels generate will go to your home usage first. If your home uses more energy than you’re getting from your panels, it sources power from the grid. To get the most out of your panels, you may want to consider running your appliances and heating or cooling systems during peak energy generation hours. Additionally, you can do the following to maximise your system’s solar power:  
Ensure your panels face the correct direction
Clean your panels routinely
Balance your consumption versus your production
You may also want to consider tilting your panels throughout the year. Keep in mind that this is easier on ground-mount systems. In Perth, the optimal angels for your panels are around 31.9 degrees. In the winter months, you want to adjust these panels by angling them at a latitude angle and adding 15 degrees to maximise their exposure from the winter sun. Additionally, some companies now offer intelligence monitoring software for your panels. This software automatically analyses how much electricity your household goes through and uses the local weather forecasts to decide when to draw energy from the grid, battery or panels. You also want to consider the warranty on your system and your battery and ensure that your warranty lasts at least long enough to see your payback period.

How Much You Can Expect to Save

The exact amount this system can save you depends on several factors. How much electricity your home uses, your peak usage hours, how big your system is, your roof’s direction, whether or not it gets full or partial sun and whether you have a battery system or not will factor in. In the interest of giving you a general idea on your potential savings, look at Nick Pfitzner’s savings. He was the first Australian resident to have a battery system installed, and his total energy bill dropped from $660 down to $50. This was in the same quarter. When it comes to solar power in Western Australia, you have an opportunity to save big on your energy bills. Take your time, do your research and make sure that you pick out the solar panel system that fits your needs. The payoff far outweighs the initial costs, and it’s environmentally friendly as well.
