Commercial solar panels, or utility solar panels are much larger than residential solar panels. The common size of a 600+ watt commercial solar panel is 2300mm tall and 1100mm wide.
Residential or rooftop solar panels are often the same with but only 1700mm tall. Residential panels are often used in commercial rooftop applications.
Commercial or Utility solar panels are ideal for ground mounted solar farms. These panels are physically bigger (Approx 2300mm tall x 1100mm wide). Many solar companies also use the large footprint 600+W commercial solar panels on rooftop installations. While this occasionally works out to be ok, often the structural engineering for these larger footprint panels causes issues. It is important to note that a 600+W commercial solar panel will not allow for more solar power on your roof.
Because the panels are larger, fewer panels can fit. In fact, it often works out that more solar can fit on your roof with the more compact residential panel. At MC Electrical, we find that on sub 100kW commercial solar systems, the smaller footprint panels (approx 1700mm x 1100mm) are ideal.
These high efficiency 440W Canadian solar panels are ideal for structural design on commercial rooftops, and are better for electrical design on medium-sized commercial inverters. Ground mounted or utility solar systems over 100kW will often use the larger dimension commercial solar panels.
Think of a commercial solar panel system as your Brisbane business’s in-house coal fire power station – minus the pollution.
Because electricity always takes the path of least resistance, when your solar panels are generating power, your business will use the energy from your power station first. This means you won’t pay to use coal-fired electricity.
If you need more power, your solar panel system will automatically buy electricity from the grid. If you have excess solar power, your solar will automatically sell it back to the grid.
Commercial solar is often a better investment than residential solar because businesses use most of their power during the day. Instead of selling power back to the grid for around 8c/kWh, you will use the power you generate and save around 30c/kWh. Because of this, the return on investment for a commercial solar system is usually even faster than a standard residential installation. The payback period for a simple commercial solar system can be less than three years.
A simple Brisbane commercial solar system will take around one day per 10kW to install.
A 30kW system will take around three days.
A 100kW system could take as long as two weeks.
Generally, this will cause minimal interruption to your business. We can arrange power outages outside of business hours.
There are pros and cons to solar energy. The main disadvantage of solar is that it does not produce power at night. A simple solution to this is to install batteries to store excess solar power. In 2024, batteries are becoming more and more economical, and it may be worth installing solar batteries for your commercial property. However daytime solar production is an advantage in commercial premises because most businesses use the majority of their electricity during the day.
Another disadvantage of solar energy is the proliferation of dodgy solar. The solar industry – as we know it – has only been around since about 2009. As with any industry that booms in a short time, cowboys come to town to make a quick buck. Strict solar industry regulations have made some progress in subduing “crap solar”. However, the solar industry is still a “buyer beware” market. You’ll want to avoid your solar investment prematurely ending up in the landfill.
Yes. Solar works perfectly to offset commercial air conditioners. Solar works best in the middle of the day and on hot Brisbane summer days. Hot summer days are also the times that commercial air-conditioners work the hardest.
Let’s assume you install 500W panel, so you need 2 panels to make up 1 kilowatts (kW). In Brisbane, a kilowatt of north-facing solar panels will produce about 4.2kWh of solar power per day (averaged over the year). Using this information, we can work out that:
Two (500W) solar panels will produce about 4.2kWh x 30 days = 126 kWh a month
100 (500W) solar panels will produce about 100 x 12,600 kWh = 12600 kWh a month.
Your solar production will be higher than 12,600 kWh this in summer and lower in winter. So 100x 500w panels should produce roughly 10,000kWh even in winter.
So to easily generate 10,000kWh of solar per month in Brisbane, you’ll need 100 x 500W panels or a 50kW system. But will this eliminate a 10,000kWh per month power bill? Read on.
It’s possible to eliminate an electricity bill with solar. However, to eliminate your power bill entirely, you will need to produce significantly more solar power during sunlight hours than you consume over 24 hours. This is because:
It costs more to buy 1kWh of electricity at night than you will get paid to sell 1kWh of solar during the day.
You will also need to offset fees and charges on your power bill (e.g.: daily metering charges).
Yes. While it’s technically not called a rebate, you can receive two financial incentives to install solar on a commercial building.
In QLD, commercial solar systems under 39kW are usually eligible for a feed-in tariff. A feed-in tariff is the amount your energy retailer will pay and credit towards your energy bill for the excess solar power you feed back to the grid. The rate they pay will vary but it is usually a bit less than the price you pay for electricity.
Commercial solar systems under 100kW are eligible to receive a “point of sale discount” called “STCs” or “small-scale technology certificates”.
In 2024 this equates to roughly $380 per kW
A 30kW system will attract a $ 11,400 incentive – or point-of-sale discount.
A 100kW system will attract a $38,000 incentive – or point-of-sale discount.
This value of STCs varies daily, so the figures above are only a rough guide.
We, like most Brisbane commercial solar companies, quote solar with the STCs already discounted off the price. So a 30kW solar system will cost around $45,000, but we will quote and charge you about $30,000.
When it comes to commercial solar inverters, reliability is of paramount importance.
Fronius monitoring (ie: SolarWeb) allows you to remotely check that your commercial solar panel system is operating normally.
In the unlikely event that there is an issue, both the customer and the installer will receive an email with information about what is causing the problem. With automated monitoring systems like this in place, we can make sure your commercial solar panel system is operational again as quickly as possible.
Without monitoring, you’d likely not notice an issue until your next power bill came in which by then could be thousands of dollars in loss.
When it comes to solar panels for commercial solar installations, Canadian Solar are a great option.
They’re an extremely high-quality panel which is important when you’re installing for commercial purposes. A large part of the installation cost is in the labour. If you were to go for an inferior panel that needed replacing after just a handful of years, you would need to pay for that labour again.
Not only are Canadian Solar panels of great quality, but they also come at an extremely competitive price. Commercial solar systems usually mean a large number of solar panels to be installed. Therefore, the price of the solar panel will make a big difference to the bottom line.
