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.

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:
