All inverters legally have to sense grid voltage to supply power. If there is a power cut the panels will stop producing, the inverter has a cut-out in it to ensure the panels don’t feed any power back to the grid when there is a power cut.
If your panels were to continue producing in the event of a power cut, it could endanger the safety of engineers working on or repairing the grid.
You will not be able to use your panels or sell anything back to the grid during a power outage.
If you want to take advantage of your battery unit(s) during a power cut, we can provide an Emergency Power Supply unit (EPS). However, this means a completely a separate circuit so another fuse board would have to be fitted to the battery. This could supply a double socket and a set of lights up to the maximum output of the battery which is 3kW. This EPS unit will not power your entire home in an outage and will only work if the battery has charge too.
You are provided with a performance estimate and savings table on your survey report after the on-site surveyor visit. We aim to give you the most accurate figures possible but please note these are not a guarantee of performance or savings.
The most common way we install panels on a flat roof is flat on dense concrete blocks. The mounting frame is attached all as one piece and weighed down by the blocks, which makes this method of installation extremely stable and secure. This pitches the panels flat, parallel to the roof face.
We can install panels at an angle on a flat roof on ballast weighted tubs, this gives the panels a 15-degree pitch – please note you may not be able to fit as many panels with this configuration due to shading restrictions.
We offer a bird mesh solution which is a strong PVC coated aluminum mesh that attaches to the exterior of the panels and acts as a barrier to stop birds nesting underneath the panels.
Every home’s consumption fluctuates constantly and regularly throughout the day, kettles, tumble dryers, lights, and turning the telly on will have an effect on the amount of power your home is consuming.
There will be instances when your home will draw from the grid before your battery, this is a necessary feature of the battery management system/inverter and is designed this way to ensure the longevity of the battery life.
If the battery kicked in exactly as and when it was needed, and there was no ramp up or down of power requirement, then the battery life would be considerably shortened.
Because of this, there may be times when it appears on your monitoring that the home is drawing power from the grid before the battery. This is perfectly normal to see, and you should see over time that the battery kicks in to supply the power.
