Commercial Solar Panel Cleaning Services in Teesdale & North East England
Keep your solar investment working at peak performance with professional cleaning from your local renewable energy experts. Serving agricultural, commercial, and industrial properties across Teesdale, County Durham, and North Yorkshire, we help businesses maximise their solar energy output and protect their renewable technology investment.
Over a decade serving North East businesses and farms
We’re not a national cleaning franchise – we’re your local renewable energy experts who installed many of the solar systems across Teesdale. Based on our family farm in Eggleston, we understand agricultural operations and commercial property needs. Our 28-strong team has the renewable energy qualifications and local knowledge that pure cleaning companies simply can’t match.
Solar specialists who can diagnose issues, not just remove dirt
As MCS-accredited solar installers with extensive SolarEdge monitoring experience, we don’t just clean your panels – we can identify performance issues, spot potential faults, and provide expert advice on system optimisation. If we find a problem during cleaning, we have the knowledge and qualifications to fix it properly. You’re getting renewable energy engineers, not just window cleaners with a ladder.
We understand working farms and business operations
We know you can’t just shut down operations for panel cleaning. Our scheduling works around harvest, lambing, peak business periods, or whatever matters to your operation. We understand farm buildings, livestock considerations, and the dust and debris that agricultural sites generate. This isn’t domestic window cleaning scaled up – it’s commercial service designed specifically for North East businesses and farms.
Maintaining Peak Solar Performance
Your solar panels are a significant investment in your business’s future. Over time, dirt, dust, bird droppings, and agricultural residue can build up on panel surfaces, reducing their efficiency by up to 25% in some cases. Here in the North East, our mix of rural farmland and unpredictable weather means panels can quickly accumulate debris that blocks precious sunlight.
Regular professional cleaning ensures your solar installation continues to generate maximum energy output, protecting your return on investment and keeping your energy bills as low as possible. Unlike domestic properties, commercial and agricultural sites often have larger arrays that are harder to access safely, making professional cleaning both practical and essential
Why choose professional cleaning?
- Peace of mind from a team you already trust.
- Safely access roof-mounted and ground-mounted arrays
- Proper techniques that won’t damage panels or invalidate warranties
- Thorough cleaning that removes stubborn agricultural residue
- Performance monitoring to identify any underlying issues
Expert Care for Your Solar Investment
With over a decade of renewable energy experience in Teesdale, we understand the specific challenges that local businesses and farms face. Our team has installed and maintained hundreds of solar systems across the region, giving us unmatched knowledge of how panels perform in our unique climate.
Our comprehensive service includes:
- Safe access to roof and ground-mounted systems
- Gentle yet effective cleaning using appropriate methods
- Visual inspection for damage or wear
- Performance checks using monitoring systems
- Recommendations for any maintenance needs
- Scheduling to suit your business operations
We work with SolarEdge monitoring systems, which means we can often identify underperforming panels before you’ve even noticed a drop in generation. If we spot any issues during cleaning, we’ll let you know straight away – and as MCS-accredited installers, we can sort any problems properly.
Ideal for Agricultural and Commercial Properties
Our cleaning service is designed specifically for business customers across the region. Whether you’re running a dairy farm with panels on your buildings, managing a commercial property with a sizeable roof array, or operating an industrial site with ground-mounted systems, regular cleaning keeps your renewable energy working efficiently.
Perfect for:
- Agricultural businesses and working farms
- Commercial properties and office buildings
- Industrial sites and warehouses
- Community buildings and village halls
- Multiple-building operations
- Any commercial solar installation in the North East
The agricultural sector particularly benefits from our service. We understand farming operations and can work around your schedule. We know that dust from harvesting, droppings from birds roosting on farm buildings, and residue from slurry spreading can all affect panel performance – and we know how to deal with it all safely and effectively.
Safeguarding Your Solar System
While there’s currently no legal requirement for solar panel servicing, manufacturers are increasingly looking at maintenance records when warranty claims are made. More importantly, regular cleaning and inspection can identify small issues before they become expensive problems.
Solar panel yields naturally decrease over time, but poor maintenance accelerates this decline. By keeping panels clean and monitoring their performance, you’re protecting the 20-25 year lifespan you expect from your investment. Our SolarEdge monitoring capabilities mean we can track individual panel performance, spotting issues that might otherwise go unnoticed until they seriously impact your energy generation.
Investment protection includes:
- Professional documentation of maintenance
- Maintaining optimal energy generation
- Early identification of potential faults
- Supporting warranty validity
- Extending system lifespan
- Maximising your return on investment
- Professional documentation of maintenance

Testimonials
In my 90th year and almost housebound I find that I have to rely more heavily on family, friends and a wide variety of firms and organisations. I have used Teesdale Renewables for many years for plumbing, heating and lighting issues. The office staff and workforce have been unfailingly efficient, helpfuland friendly over that time.Very recently I had a new central heating boiler installed and replacement lights fitted in the porch and under kitchen cupboards. The boiler change was completed within the day causing minimum disruption to the normal function of the house in respect of water and gas supplies and is proving to be very efficient and effective. The lights were installed in a few hours and are superb.I would never think of going anywhere else for the services provided by Teesdale Renewables so effectively and at reasonable cost.
Thank you for the excellent service from staff member of the electrician team- he was very capable, experienced and well mannered. I will definitely be using your services again.
Thanks for the invoice for the installation of our wood burning stove. We are delighted with the stove and with the work undertaken.
Frequently Asked Questions About Solar Panel Cleaning
How often should commercial solar panels be cleaned?
For most commercial and agricultural sites in the North East, we recommend cleaning every 12-18 months. However, farms with intensive livestock operations or properties in particularly dusty locations may benefit from more frequent cleaning. We can assess your specific situation and recommend an appropriate schedule based on your panels’ location, orientation, and the activities around them.
Will cleaning really make a noticeable difference to energy generation?
Absolutely. We’ve seen panels recover 15-25% of their output after thorough cleaning, particularly on farm buildings where agricultural dust and bird droppings accumulate. With commercial electricity prices where they are, that efficiency gain translates directly to meaningful cost savings. If you have monitoring in place, you’ll often see the improvement immediately.
Is it safe to clean solar panels myself?
We wouldn’t recommend it for commercial installations. Working at height carries serious risks, and using incorrect cleaning methods or too much pressure can damage panels or invalidate warranties. Our team has proper training, insurance, and equipment to access and clean panels safely – whether they’re on a barn roof or a ground-mounted array next to your cattle.
Do you need to turn off the solar system for cleaning?
Generally, no. Modern solar systems can remain operational during cleaning. However, we’ll assess your specific installation and let you know if any temporary shutdown is needed. We work efficiently to minimise any disruption to your energy generation.
What about panels that are difficult to access?
Difficult access is exactly why many businesses use our service. We have the equipment and training to safely reach panels on steep roofs, tall buildings, or awkward locations. Whether your panels are mounted on a three-storey barn or spread across multiple buildings, we’ll work out the safest and most efficient way to clean them properly.
Will cleaning affect my warranty or any performance guarantees?
Professional cleaning by qualified technicians should never affect warranties – in fact, proper maintenance often helps support warranty claims by demonstrating you’ve cared for the system properly. We provide documentation of all cleaning and inspection work, which can be useful if you ever need to make a warranty claim. As MCS-accredited installers ourselves, we understand manufacturer requirements and clean panels using approved methods.
