Case study – commercial roof top solar
Snow White Laundries Cardiff & Pontypool
Snow White Laundries is a multi-site commercial laundry company that offers full contract laundry services to some of the largest hotel groups, hospitality companies and restaurants in South Wales and the West. They have approximately 70,000 square feet of production facilities at their plants in Cardiff and Pontypool. Solvo Energy were contracted to provide solar panel installation, electrical installation and commissioning services to both sites.

Annual Electricity Generation
The Solvo solar PV system will reduce Snow White Laundries electricity bill by approximately £94,581 per annum and will pay for itself in just 3.41 years. The solar system offer will offer savings of £2,979,301 over the systems 35-year life.
Preliminary system design produced by the Solvo Energy engineering team utilising inhouse computer aided software.
System FunctionalityThe installed system will function under three primary operational scenarios:
Generating Excess Solar
During summer daytime hours the system may produce more energy than required on site, and so excess energy is sold to the grid.
Partially Offset Usage
During winter daytime hours the system may not produce enough energy required to fully power the site. In this case, excess energy is purchased from the grid to supply the deficit.
Overnight
As solar PV does not generate electricity outside of daylight hours, no power is generated, and all electricity must be drawn from the grid.
Solar PV generates on site green electricity which offers significant electricity bill savings and reduces carbon consumption thereby providing a contribution towards the UK’s journey to Net Zero. Future installation of a Battery Energy Storage System (BESS) will allow for utilisation of the system overnight and increase annual savings.

Environmental Benefits
Solar PV produces no CO2 emissions when generating electricity, creating a completely clean source of green energy. Environmental benefits provided by this system over its 35-year life cycle include:
2,056
Estimated tonnes avoided CO2
9,553,890
Car miles avoided
63,741
Trees planted
2,467
Long haul flights avoided
