Warning light? No generation? Or is it just not performing as it was? We can help, even if we didn’t fit your original system.

Keep your system performance at the optimum, helping you maximise your investment.

Solar PV is a relatively low-maintenance technology: little should go wrong with a well-built system. However, software updates or component failure can cause unanticipated problems as with any complex technology. Warranties vary from brand to brand and even between products and models.

It could be a faulty generation meter, damaged panel or inverter that needs upgrading to keep your system running at its best. Sometimes, replacements are required to keep your system up and running.

Worried about your FIT payments? We can maintain your system and install most upgrades without affecting your existing export tariff.

Bought a home with solar and don’t know where to start? We’ve got you covered!

Whether it’s a newly built home or an older home with an existing system, we know the technology can be a lot to get your head around. We also know that the installers that take on big new build developments may not be able to offer the same personal service we can due to the sheer scale of their operations. We’re here to help.

We can advise you on your current system and advise on tariffs and options to get the most out of the system you already have. Our introductory call is completely free of charge and with an engineer, not a salesperson so you can relax – you’re in good hands.

System Upgrades


Bird Protection

Due to the nature of panels being on your roof, birds and other pests can make a home under your panels, causing damage and being a nuisance. We offer both aesthetic and budget options to suit your system and desired look.


Additional Batteries

Adding a battery is a no-brainer if you are generating more than you can use and exporting a lot back to the grid. Instead of exporting that energy, you can store it in a home battery to use later that evening. The best bit, it won’t impact any FIT payments!



If you have a hot water tank, we can use excess energy from your solar to heat your hot water with the Eddi diverter. The eddi helps you make the most of your self-generated energy, rather than exporting it back to the grid.
