*Prices are shown after applying the 30% federal tax credit.
As of Sep 2024, the average cost of solar panels in Belgium is $2.48 per watt making a typical 6000 watt (6 kW) solar system $10,421 after claiming the 30% federal solar tax credit now available.
This is lower than the average price of residential solar power systems across the United States which is currently $3.00 per watt.
The size of a solar panel system also plays a role in how much the installation will cost.
Larger solar installations will typically have a lower cost per watt, because the panels can be purchased at a ‘bulk price’. However, these larger solar systems will still have a higher total cost, because they are made up of more individual panels.

Of the three companies I interviewed for installing solar panels on my garage, I'm very happy that I selected All Energy Solar! I was impressed by how much the staff I encountered enjoyed their jobs, cared about their customers, and were dedicated to providing high quality work. I'd like to give a special shout-out to Brandon Charboneau (Sales Consultant), Paris Gronberg (Project Manager), and Installation Crew #8 (Andrew, Alex, John, and George). I found them all easy to work with, they were respectful of my property, and they answered my many questions without hesitation. Alex did a masterful job of handling the electrical installation. John and George had to hand dig a 2' deep trench from my garage to the electric meter behind my house (a distance of 70'). They were careful of my flower beds and a nest of baby bunnies they found right by where they were digging. Thanks guys!

This was our second solar installation. The first was with a different company, which gives me a little basis for comparison. From the start, our salesperson at CertaSun was very knowledgeable, but more importantly, very frank and un-pushy. The conversation was just us asking questions, him generously sharing his time and information, and us both figuring out what makes the most sense for us. It was clear he was not trying to railroad us into the biggest system he could, which I really appreciated. After that, everything went smoothly. The biggest difference between CertaSun and the company that did our first installation is the level of communication. CertaSun responded right away to emails and, better yet, they gave us a lot more information and contacted us whenever there was any update, so we just had fewer questions as the process unfolded. The installation all happened on schedule. CertaSun facilitated easy financing so that we didn't pay out of pocket for the amount that will be reimbursed through tax credit. CertaSun took care of the permitting and inspection through to switching on the panels. I'm confident that we have a reliable partner that we'll stick with for any needs going forward.

We had our 30 panel system installed in July of 2023. Arch did a great job and I have no problems with their product or installation. But I would recommend installing solar panels on newer roofs. Our roof was about 15 years old at the time and with panels rated for a 25-30 year life span, be sure to understand the cost of having panels removed and reinstalled when a roof needs to be re-shingled. When we bought through Arch we asked that question and were told by the sales rep that it was around $4000. In July of 2024 we had to have our roof shingles replaced due to hail damage, and Arch Electric charged $14,700 to have the panels removed and reinstalled. Luckily our insurance covered the cost but if that was not the case, this would have negated any long-term financial benefits of a solar system.

We had a home installation that went very smoothly. Mike from Full Spectrum assisted us with applying for tax credits and in our hookup with the local power company. Things were seamless and we are currently up and fully functional. Staff was friendly and efficient and costs were as predicted. We are very happy with the results so far. Installation was in late December so we are about 3 months out.

Steve and John were very helpful and professional from the beginning to the end on my solar panel project, the installation process went well and without any added costs. Their crew were also very professional, it sure is nice not having a electric bill.

I had an awesome experience with Greenify Energy Savers. My upgrades included: window installation, solar panels, electric panel upgrade, attic insulation and radiant barrier. Wyck and Marleen were available and trustworthy throughout the process. Their team always showed up as planned, and did great work. The actual price matched the bid with different financing options, no surprises. Feels nice to run off the sun :)

Where there is no specific pricing information available for a brand then we have used state pricing data for that brand.
Solar panel manufacturer | Avg. cost per watt |
---|---|
Canadian Solar | $2.31 |
LG Solar | $2.76 |
SunPower | $2.89 |
Panasonic | $2.79 |
LONGi Solar | $2.23 |
The most important difference between buying solar panels and any other purchase is that solar panels last 25-30 years. This is a long, long time and you will need customer service over all that time. The reviews below of the two largest corporate solar installation companies indicate larger corporate solar companies are not delivering this support to their customers.
We recommend you find a small or mid-size, local, family-owned solar company. These companies tend to care more about you and your specific job. You don't want to be on hold to a corporation's call center for the next 25 years!
The cost of solar doesn't just include the equipment and installation costs - it’s also made up of permitting costs, inspection costs, and installer profit margins.
These different components are what make the price of solar fluctuate between installations. Some of the factors that affect solar power system installation costs for specific homes include:
Homes that use more electricity will need more solar panels to cover their energy needs.
Although solar panels do get cheaper on a per-watt basis, the overall cost of the system will increase as more panels are added.
But, the higher a home’s energy usage, the more solar panels can save the homeowners on their energy bills.
The price of solar panels can vary depending on the type of solar panels you choose.
There are two main types of solar panels for residential solar installations: monocrystalline and polycrystalline. Monocrystalline solar panels tend to be more efficient and more expensive than other solar panels. Polycrystalline panels have a lower efficiency rating and come at a lower price point.
The type of inverter you buy will also influence the cost of your solar system.
You may see some solar quotes with prices that seem too good to be true.
If you get quoted for a ridiculously cheap price, the installer might be using low-quality equipment or an unsustainable pricing model. You want to use a solar installer that is charging enough so that they can stay in business - as you’ll be relying on them for the next 25 years!
It’s important to make sure that your installer is giving you the best quality at the best price possible. This is why getting multiple solar quotes is so important.
The overall cost of solar can be influenced by the solar incentives available.
Across the U.S., homeowners can apply for the federal solar tax credit. The solar tax credit makes installing solar more cost-effective by providing homeowners with a tax credit equal to 30% of the cost of their installed solar panel system.
Local solar tax incentives and rebates can end up saving homeowners thousands on a solar installation, especially when they’re used with the federal solar tax credit.
See what solar incentives are available in your area by using our solar panel calculator.
The cost of installing residential solar panels in Belgium varies with the brand of solar panels and inverters you choose, the installation company you choose to install them, the relative ease or difficulty of installing solar panels on your home, and of course the amount of solar panels you need. The amount of solar panels you need is, in turn, related to your energy usage.
The table below shows the data extracted from a real life quote delivered through the SolarReviews marketplace recently for a fairly typical home in Belgium.
As you can see the payback period is relatively short and equates to a much better return on investment than he historical returns that have been available from investing in things like shares or property.
System information | Value |
---|---|
System Size (for 100% usage offset) | 10.47 kW |
Annual power generation | 13,042 kWh |
Pay-back time (assuming Cash purchase) | 9.6 Years |
Internal rate of return (IRR) on investment | 5.9% |
Gross cost | $27,803 |
Total Upfront Incentives and Rebates | -$7,228 |
Net Cost of System after rebated and incentives | $20,571 |
Total Cost of Utility Power Avoided over 25 years | $68,858 |
Please note that the investment return figures do not include the possible increase in property value
