If you have solar panels on your house, this page explains how you can get the most benefit from the free, sustainable electricity they provide and how you might use them to reduce your energy bills.
When do solar panels generate the most electricity?
Every home is different, but here are some general guidelines:
Solar panels typically generate the most electricity around
noon, when the sun is at its highest point.
Longer days and a higher sun angle mean more electricity is
produced in summer. In winter, shorter daylight hours and less
intense sunlight means less electricity is made.
Clear skies mean more sunlight and more electricity. Check the
weather forecast or simply look outside to gauge how much
power your panels might produce.
If you have a smart meter with an in-home display, this may
show when electricity is being exported. If it does, you can use
this learn when your peak times are. If you’d like help with this,
contact our Home Energy Advice Team on 0300 120 120.
How to use electricity when it’s being generated
If you know when your panels are generating electricity, to use the most of the free electricity, you'll need to know which items to use and how to use them.
Run appliances like washing machines, dishwashers, and
tumble dryers during sunny midday hours to reduce your
electricity bill.
Running multiple high-energy appliances at once may exceed
the electricity your panels generate. Spread usage across peak
times.
If your appliances have timers, set them to start just before
peak generation times to maximise solar usage.
Frequently asked questions
Solar panels have no moving parts and last around 25 years.
The systems are monitored remotely and we have a five year
service programme.
If we carry out work on your roof, we’ll ensure the panels are
returned to their original position.
If you do notice any issues, contact us on 0300 120 120.
No, for safety reasons, in the event of a power cut, the system
will automatically switch off and switch back on when safe to
do so.
We are installing netting around solar panel systems to prevent
birds nesting. If your panels don’t already have netting, contact
us on 0300 120 120 to find out when yours will be installed.
