What are solar photovoltaic (PV) panels and how does the system work?
Approximately 50% of Colchester Borough Council’s housing stock benefits from solar PV. The panels on the roof are divided into arrays, between 8 (2kW) and 16 (4kW) panels per array, and one array to one property. These are connected to an inverter, either installed in the loft space or in a cupboard close to the property’s fuse board and sit alongside a generation meter. We ask that residents do not touch this equipment, as it remains the property of the PV installer.
How can solar photovoltaic (PV) panels help me save money?
Colchester Borough Homes suggests best practice to realise savings but cannot guarantee how much anyone may save as we each consume energy differently. It is strongly recommended that electrical usage is spread or staggered throughout the day, using one appliance at a time where practical.
Residents who have concerns regarding their electricity bills and who have looked at their usage should contact their supplier to ensure that they are on the correct tariff. All PV systems were registered at the time of installation, so all energy companies will hold records to show that the property benefits from PV so should be able to find the best plan for each person’s requirements or be able to discuss billing in greater detail.
I have noticed flashing lights on the inverter – is this normal and do I need to report it?
The frequency of the flashing relates to the amount of sunlight outside. It is entirely possible that it will flash a lot on a cloudless winter day but nowhere near as much the following day if it is raining or overcast. The systems send half-hourly signals to an online portal, meaning that those responsible for monitoring the system are aware of a fault almost immediately and will often contact residents directly to arrange an appointment to inspect the system, if necessary. There is no need to monitor the lights on the inverter or the smaller generation meter.
There appears to be a banging or rattling noise during high winds – is this normal?
Where it is felt that the noise has become a loud bang please contact Customer Services for the issue to be referred to the relevant investors’ maintenance contractor.
