Case Study: Wickman

Green Energy Solutions for Sustainable Business


Wickman is a global supplier and manufacturer of multi-spindle lathes, designed to produce medium and large volumes of extremely precise, high-quality components for all parts of the world. With offices based in the UK, Brazil, USA, China & India, they are a true global player. Reducing their carbon footprint and making a solid financial investment were essential for all stakeholders.

The Challenge

Wickman faced rising energy costs and wanted to transition towards a more sustainable and financially secure energy source. They were looking for a reliable, cost-effective, and environmentally-friendly solution.

The Solution

After a comprehensive assessment of their energy needs, our team recommended the installation of a state-of-the-art commercial solar PV system. The system was custom designed to maximise energy production while minimising environmental impact.

Key Features of the Solar PV System

Capacity: 115 kWp

Components:  High-efficiency solar panels,
advanced inverters, and a robust pitched
mounting system.

Location:  Multiple rooftop mounted
installations were strategically chosen to
optimise sun exposure.

Monitoring System:  A sophisticated real-time
monitoring system was implemented to track
energy production and identify any performance
issues promptly.


Energy Independence:  The solar PV system now covers 57% of their energy needs,
significantly reducing their reliance on the grid and providing long-term energy cost stability

Environmental Impact:  The system reduces CO2 emissions by almost 21 tons annually,
equivalent to planting over 969 trees each year.

Financial Savings:  They are projected to save over £37,985.84 per year in energy costs, with
an estimated payback period of just over 2 years. They have offset their energy bill by 91%.
The energy costs from the solar array cost them £0.03p per kWh, which is a locked-in price
over a minimum of 25 years.

Positive Brand Image:  The transition to renewable energy has garnered positive attention
from customers, stakeholders, and the community, enhancing their reputation as an
environmentally-conscious manufacturer.

Maintenance and Support:  Our team provides regular maintenance and performance checks to ensure the system operates efficiently. A 25-year warranty covers the PV modules and a 7-year warranty covers the inverters.

KAST offers 1-year workmanship warranty as standard that can be extended to 5 years along with a yearly servicing package for peace of mind.

The implementation of the commercial solar PV system has not only met but exceeded the client’s expectations. They now stand as a shining example of sustainable business practices, demonstrating how solar energy can be harnessed for both economic and environmental benefits.
