Solar PV System Repair Service
There are a couple of non technical ways to find out if the solar panels are working:At the solar inverter:The solar inverter sits at the centre of a solar PV system and is the piece of equipment that converts the DC power generated by the solar panels into AC power for use in the home and export to the mains/grid. Most solar inverters have LCD displays on the front which will show the status of the system. If the solar panels are working and the solar inverter has a display, it will likely show you here. Most solar inverters have lights, they are all different but a solid green light suggests that the solar PV system and the solar inverter is in operation. A solid light of any other colour suggests a fault, further information will hopefully be available at the solar inverter`s display.
Common measurements that are displayed on the LCD screens of solar inverters are:
- The DC voltage (V) from the solar panels
- The Current measured in Amps (A) from the panels
- The overall power measured in Watts (W) being generated by the system
- Mains/grid/feed-in voltage is sometimes also displayed
Solar inverters are usually around the size of a small TV or a microwave oven (there are pictures of solar inverters further down this page), if you can`t find the solar inverter in the house, these are often installed in loft spaces and adjoining garages.
At the Solar PV generation / Feed in Tariff (FIT) meter:The solar generation meter is a small piece of equipment (picture further down this page) that counts all of the solar power that has been generated by a solar PV system in kWhrs.
Common places for these to be installed are:
- Near to the main consumer unit/fuse box
- Near the incoming mains/grid supply meter, you can sometimes find these in a box on the side or front of a house
- In a loft space or garage, if this is where the rest of the solar PV equipment has been installed
If the solar panels are working, the solar generation meter will count the power that the solar PV system generates, this power is measured in kWhrs and counts all solar generation, you will see the numbers increase on the display and the red light will flash as it counts.
