Watson-Marlow Limited - Solar Panel

Watson-Marlow have world renowned expertise in peristaltic pump manufacturing and fluid path technologies.

A unique offering of supplying our own precision tubing, manufactured in-house.

Sterility & cleanliness manufacturing to the highest standard for our tubing, gaskets, flow restrictors & tubing connectors in ISO Class 7 cleanrooms.

Our peristaltic pumps have no valves, seals or glands, giving our pumps a unique advantage for ease of maintenance and reliability.

Watson-Marlow would very much like to introduce Watson-Marlow's first on-site electricity generation system with rooftop solar arrays. Up until now, all of Watson-Marlow Ltd has been will attaining our energy needs from stationary combustion sources and grid purchased electricity. We have no renewable generators/microgrids of our own. We would like to put one rooftop solar array on our tubing extrusion building, T2, and a second rooftop array on our pump assembly and tubing building, T1. Both buildings are on our estate and are ~40 m apart from one another.

We wanted to ensure we were fully prepared for this grant application to give over accurate costing, annual energy production values, carbon savings and proposed timelines for installation. We brought 3 solar installers to site to survey and quote to provide an inclusive turnkey solution. A breakdown of the system is as follows:

T2 building:

1. 641 panels
2. Annual energy production = 240,555.84 kWh/annum

T1 building:

1. 345 panels
2. Annual energy production = 130,137 kWh/annum

Short-term impact - a completed rooftop solar array providing an instant carbon saving and less reliance on the grid.

Medium-term impact - certainty over long-term energy pricing and our utilities buying strategy with our broker.

Long-term impact - a solar array that will stand the test of time fir 25+ years, knowing that our T1 building was erected in 2005, and T2 in 2009, respectively.

Regarding operational impact, we will see very little disruption - we could safely manage contractors atop the roofs during normal operational hours, and only upon commissioning of the solar system to connect to our mains electrical board, shall we require a whole building isolation. This could take place over a weekend as we currently operate 24/5.
