How Much Power Does a Commercial Solar Panel Generate
Are you wondering how much energy your business could really generate from solar panels?
At Easy Being Green, we've helped thousands of Aussie businesses and households harness solar energy. One of the most common questions we hear is exactly how much energy a commercial solar panel can produce. Let's clear that up.
What Influences Solar Panel Output
Commercial solar panels typically generate anywhere from 250 to 450 watts each under ideal conditions. But here's the catch—ideal conditions don't always exist. We’ve noticed that several things can impact this number. These include sunlight hours, weather conditions, the panel's angle, and how clean the panels are.
On a bright summer day in Sydney, you could realistically expect about 4 to 5 hours of peak sunlight. That means a 350-watt panel could produce roughly 1.4 to 1.75 kWh of energy each day. But don't worry if you're based in Melbourne; you'll still get decent output, even if the weather changes throughout the day.
What We've Seen in Real-Life Installations
We've installed systems ranging from small businesses to large warehouses. For instance, a typical 100 kW commercial installation generates around 350 to 450 kWh per day. Over a month, that could easily exceed 10,500 kWh. That's enough to significantly cut your energy bills and reduce reliance on grid electricity.

Does Size Really Matter for Commercial Solar Panels?
You bet it does. The physical size and wattage rating go hand in hand. Bigger isn't always better, though. We've found that panels around 350 watts offer a great balance of space efficiency and cost-effectiveness. Businesses we've worked with often prefer these mid-sized panels as they deliver great results without taking up too much roof space.

More Panels or Higher Efficiency?
While adding more panels is one option, we've learned that using efficient, high-quality panels gets better long-term results. A few top-quality panels typically outperform a larger number of lower-quality ones. High-efficiency panels often generate more energy even on cloudy days, making them ideal for Australia's varied climate. If you're curious, here's more on how solar tech works in Australia.
Battery Storage Makes a Difference
We recommend pairing your solar setup with battery storage, especially if your business operates beyond daylight hours. Solar batteries help store excess energy during peak sunlight, ready to use when the sun sets. For a deeper dive, our solar batteries page explains how storage solutions can maximise your solar investment.
Real-Life Examples You Can Relate To
One business we partnered with saw their energy bills drop significantly after installing a 142 kW system. On average, they saved thousands of dollars monthly, a clear indication of how effective commercial solar panels can be.
We’ve also noticed smaller setups like a 40 kW system consistently produce around 140 to 180 kWh per day, enough to power a medium-sized retail space. If your business is in Sydney, our commercial solar Sydney service might be just what you need.
Some Common Misconceptions We've Heard
Many people assume that solar panels produce their rated power output consistently all day long. That's actually far from reality. Solar output peaks during midday and drops off sharply as the sun lowers. Another misconception is that solar panels only work in direct sunlight. They actually generate energy even on cloudy days—just a bit less efficiently.
What to Expect Over Time
Solar panels generally come with a 25-year performance warranty. That means they'll continue producing at least 80% of their original rated output even after two decades. So when we say solar is a long-term investment, we truly mean it.

Solar's Impact Goes Beyond Energy
By choosing solar, you're not just cutting down electricity costs—you're also contributing significantly to the environment. Each kilowatt-hour your solar panels generate is a step towards reducing Australia's carbon emissions. Our projects alone have prevented millions of tonnes of carbon pollution, equivalent to removing around 1.2 million cars from the road.
That's something we're incredibly proud of.
