Common issues with Solar PV systems:
  • Reduction in electricity generation
  • Loose electrical connections
  • Faulty parts including inverters

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 and Growatt and SolaX battery storage systems.

Maintaining your Solar Energy System
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.

Comprehensive Health Check

Reviews - What our Customers Say...

"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."                                                                                                                                                                                                                                             - P Manley, April 2017
