Mypower customer installs solar PV at second site and looks forward to £175,000 of savings and income

Rocket Rentals

Rocket Rentals is a family run business offering plant and machinery hire and sales in Gloucestershire.

In 2011 Mypower installed a 10kWp  industrial solar power system at their premises near Cam. The business has now outgrown the existing site and they built their new commercial workshop and offices this summer. Having seen fantastic returns and won a major plant hire contract for sustainable homes following their investment in renewable solar energy they knew they wanted to install solar PV again on their new building.

Mypower were contacted prior to construction so we could advise on and provide any hints and tips before building work commenced. We advised on several points such as electricity connection, timing of the industrial solar install with existing scaffolding and netting as well as design and layout, all of which saved them money.

Whist Rocket Rentals could fit 34 kWp on the roof, we provided our usual honest professional advice and suggested limiting it to 30 kWp to avoid the additional export metering costs and charges.

With 70% of the solar electricity generated used on site the 115 REC solar panels will produce savings and an income of £175,000 over 25 years. This means they have effectively forward bought their electricity at 4.5 pence per unit compared to an estimated 13 pence per unit from a mainstream energy supplier. Of course this also means they are not exposed to any electricity price rises in the future from their solar electricity.

Solar panels were installed during construction of the new building which helps with cost savings

Simon Tomblin, Managing Director, Rocket Rentals commented, "As we have expanded the business, our power costs have increased. With solar offering cheaper electricity, a good return on investment and the commercial benefits of being a "green" plant hire Company, it was not a difficult decision to make. The solar will also really help us towards our ISO 14000 accreditation.

We were very pleased with the first installation Mypower did for us in 2011 and had no qualms in asking them to quote the industrial solar panel cost for our new building. The upfront advice received from Mypower was very helpful and their involvement with WPD saved us some money. Ben worked with us every step of the way to dovetail the installation in with the erection of the new building, saving us money on access and scaffolding. He was very professional in all that he did, taking control but keeping us fully informed throughout the project and dealing with all the paperwork. The installation team were friendly, helpful and flexible with all going to plan and the deadlines being met."

Ben Harrison who heads up Mypower said "It was a pleasure working with the team from Rocket Rentals again. They deserve the success they have achieved and the solar panels will help contribute to their future growth".
