Case Study: Primary School

Green Energy Solutions for Sustainable Business


This Primary school wanted to become more green and less reliant on grid-supplied energy as their energy costs were increasing year on year. They wanted to ensure that any investment made would benefit them for decades to come.

The Challenge

Facing rising energy costs, they 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 designed to maximise energy production while minimising environmental impact.

Key Features of the Solar PV System

Capacity:  37 kWp

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

Location: A single rooftop mounted installations
were strategically chosen to optimise sun

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 27% 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 7.6 tons annually,
equivalent to planting over 302 trees each year.

Financial Savings:  They are projected to save £10,876.60 per year in energy costs, with an
estimated payback period of just over 4.3 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 our 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.
