How Business Solar UK Can Help With Commercial Solar Panel Maintenance

We’re a leading comparison tool for business owners just like you. It’s our job to find you the best local expert commercial solar installers that match your requirements. That saves you an awful lot of comparison time and money, because you can be confident the installers we match you to are all vetted as professional and trustworthy.

But how do we match you to the right installer? Well, that’s all simple enough:

  • What you’re looking for (in this case commercial solar panel maintenance)
  • Installer reputation
  • Both of your locations 
  • The best deals for you

We’ll then send you the details of any local installers we’re confident are right for you, and then you take it from there.

The Importance Of Maintaining Your Panels

Solar panels, in general, require very little maintenance over the course of their lives. Many are self-cleaning due to the rain, and most don’t have moving parts, meaning wear and tear is less of a problem. 

With that said, you can’t just install your commercial solar panels and then forget about it. Doing so will significantly reduce the life of your solar panels. The longer your solar panels last the better it is for you, because as soon as they’ve paid for themselves you’ll be making significant savings – the longer they last, the more savings you’ll make. 

Of course, if we’re having a particularly good summer in the UK with little rain, you’ll need a little more maintenance to ensure they’re in proper working order. 

Consequences Of Failing To Maintain Your Commercial Solar Panels

You might be in need of commercial solar panel maintenance if you notice any of the following issues, as they’re all consequences of a poorly maintained solar panel system:

  • Your energy output is lower than before 
  • You notice signs of dirt or debris 
  • You notice warning lights on your panels, inverter, etc
  • You have defected or old parts in your system
  • It’s costing you more to run your solar panels and power your business

Essentially, your solar panels will start to deteriorate much faster without some form of commercial solar panel maintenance.

Is Commercial Solar Panel Maintenance Included As Standard?

That depends on your solar installer and your arrangement at the time of your installation. If you have already had your commercial solar panels installed, then it may be worth checking if you already paid for a maintenance package as part of it. 

If you didn’t have a maintenance package arrangement in place, or you haven’t had your commercial solar panels installed yet, but you’re thinking ahead and trying to find an installer that also offers commercial solar maintenance, then you can work with us. 

We’ll trawl through our extensive list of local solar panel installers to you, and find you the perfect match. 

What Does Commercial Solar Maintenance Entail?

Maintenance can be broadly split into a few main categories:

  • Preventative action 
  • Reactive action 
  • Testing & inspecting 
  • Cleaning 
  • Monitoring

Preventative Action

This might involve things like replacing parts before they’re too old, completing a full system test to ensure there are no issues, and making sure any potential faults are picked up early to prevent problems from occurring and keep your system in full working order so your business is always powered by solar. 

Reactive Action

This could involve things like repairs on broken components, replacing solar panels, and responding to fault and warning lights showing on different parts of your system – obviously with regular maintenance reactive action shouldn’t be necessary.  

Testing & Inspecting

Testing and inspecting is part of most solar installers’ annual commercial solar panel maintenance package, if they offer it. It basically involves a full system test and inspection that looks at your solar panel array’s performance to ensure it’s performing as it should be for your business. 


It might seem simple, but cleaning is such a vital part of any maintenance service because dirt and debris can easily ruin your system’s performance. With a thorough cleaning, though, your solar panels can return to their former glory, providing you with the energy and savings you would expect.


Some commercial solar panels are installed with a full 24/7 monitoring system designed to flag any issues early, meaning you could benefit from support much quicker. You can also carry out some of this monitoring yourself with visual inspections from ground level and keeping up to date with your energy output levels so you can spot any changes quickly.

Commercial Solar Panel Maintenance FAQs

As a minimum it’s recommended that you have your commercial solar panels looked at by professional installers once a year. If the summer is a particularly dry one, you may need additional maintenance to keep them clean and free of dirt and debris to work more efficiently.

Most modern solar panels come with an expected lifespan of 25 years with the proper maintenance and care throughout their lifetime. Some can even last up to 40 years. 

One thing’s for sure; the better you care for them, the longer they’ll last. 

That depends on the installer you choose from us. Different installers offer different package deals. But when you compare local installers with us, you can be confident you’re getting the best possible deals in your area.
