Our Services:
Fault Finding and Repairs
Even though solar PV systems are generally very reliable  sometimes things do go wrong. If your system stops generating energy or doesn't seem to be generating as much as it used to, one of our expert engineers can come and assess system, identify the problem and resolve any issue quickly and efficiently to ensure that your Solar PV System is back to full working order as quickly as possible. All of our call outs include up to 1 hour of labour and often we can resolve any problems within this period.

Common issues with Solar PV systems:
  • Reduction in electricity generation
  • Loose electrical connections
  • Faulty parts including inverters
  • Damage by pests such as pigeons
  • Storm damage
The most common inverters we deal with are manufactured by SMA, Fronius, Mastervolt, Arura, SolaX, Solis, SolarEdge, Afore and Growatt although we can service any other kind of solar inverter. We are also familiar with the Maslow, Goodwe, Growatt and SolaX battery storage systems.

Comprehensive Health Check

Solar Photovoltaic systems don't have a lot moving parts that can fail so they don't require a huge amount of work to keep them in good working order. However, as with any technology, the better care you take of it the longer it will last. In order to make sure that your solar panels are performing at their best efficiency it is recommended that you arrange a regular health check to make sure that they live a long and happy life, supplying you with all clean energy, savings on your energy consumption and protecting your investment.e. In addition to all the standard checks and controls our engineers will also:

Customer Reviews

Anonymous Posted 8th Nov
A professional experience from my telephone call for help as renewing the solar generation failure by the friendly and informed electrician
Customer in Seaford Posted 22nd Aug
Excellent
Customer in Sidcup Posted 17th Aug
Very efficient, professional work with knowledgeable answers to questions about solar systems
P Manley Posted 8th Apr
Rayotec installed our Solar PV system so when the inverter failed, typically only months after the manufacturer's warranty expired, I contacted them about a replacement.

I spoke with Reza who gave me two options with prices and when I had made my decision Reza kept me informed of progress of the order and the install date. The wait time for installation was only one week and good communication was maintained throughout this period.

Dave came to install the new inverter and he was excellent. He was punctual, very efficient with a high level of expertise, very helpful and always polite - a credit to Rayotec. When Dave identified a further problem with my panel array, caused by nesting Jackdaws between the panels and the roof, he was again very knowledgeable and helpful in recommending a pest control company who could resolve the problem.

I am very happy with the service I received from the Rayotec Team and cannot recommend them highly enough.

I've had underfloor heating and solar panels fitted by Rayotec, I'm very happy with both the work done and the top service they gave me. They are friendly, professional, I had a small problem with the boiler system, which they very kindly took the time to explain how it all worked so the issue was resolved.

They really went above and beyond the call of duty, and I recommend them highly to others, no problems at all. I'll be booking them again for another job on another property very soon.
