How Roys is Going Solar

At Roys we're committed to helping the environment and trying to save energy. We've installed over 3,700 solar panels on the roofs of 8 of our stores including Wroxham supermarket, department store, Bowthorpe, Dereham, Sudbury, Beccles and Thetford variety stores. We've also installed them on the roof of the department store building at Highway Garden & Leisure. In most cases the panels are not visible from the ground and can only be seen from the air.

The panels were supplied and installed by Sands Renewables, a local company based in Norwich, Norfolk. They specialise in Solar PV (photovoltaic) panels which generate energy from radiation meaning that it doesn't need to be particularly sunny in order for them to work.

Roys joined the Carbon Trust in 2005 and since then have made a number of changes to our stores to help save energy such as installing energy efficient light tubes, better refrigerators and energy optimiser units in our larger stores. Each store has an energy champion to pinpoint cases of energy being wasted.

What is a kWh?

kWh stands for Kilowatt Hour and is a measurement for energy usage that equals the amount of energy you would use if you kept a 1,000 watt appliance running for an hour. For example, if you switched on a 100 watt light bulb, it would take 10 hours to use up 1 kWh of energy. A kWh is the standard unit for measuring energy usage and is used by all major energy companies. You should be able to find how many kWh you've used in your own home on your electricity bill.
