How Evolution Solar Helped David Stewart Go Greener and Save More
At Evolution Solar, we pride ourselves on providing expertly designed energy systems that help homeowners reduce costs, increase energy independence, and move toward a greener future. This case study looks at a recent installation we completed for David Stewart in Sherborne.
With rising energy prices and growing concerns over power reliability, David turned to us for a comprehensive solar and battery solution. Here’s how we helped him achieve reliable, clean energy for years to come.
What Was the Customer Looking For?
David contacted us looking for a long-term energy solution that would do three things: reduce his electricity bills, provide battery backup during outages, and improve the energy efficiency of his home. With energy prices unpredictable and the risk of power cuts becoming more common, David wanted to future-proof his property.
He was particularly interested in installing a system that would support his growing electricity usage, including charging an electric vehicle and running high-energy appliances. The idea of having a smart backup system was also appealing, offering peace of mind during winter storms or unexpected outages.
David came to us on the recommendation of a previous client; something we always value highly. Word-of-mouth referrals speak volumes about the quality of our work and the trust our customers have in us.
What Was Installed on the Property?
We installed a tailored, high-performance energy system designed to meet David’s needs for independence, backup power, and savings.
This included installing the following components:
- 12 x Aiko 455W Solar Panels
- Tesla Powerwall 3 with Backup Gateway
- Zappi EV Charger
Each component plays a vital role in enhancing energy efficiency and independence. The Aiko solar panels are known for their high output and durability, converting sunlight into electricity even in low-light conditions.
The Tesla Powerwall 3 provides a robust backup solution and stores excess solar energy for use in the evening or during outages.
Meanwhile, the Zappi EV Charger allows David to charge his electric vehicle using the solar energy generated on-site, significantly lowering fuel costs and carbon emissions.
How Did Evolution Solar Deliver?
From the first consultation to the final panel, our team prioritised quality, safety, and cleanliness. The installation process was smooth and completed with minimal disruption. Our engineers ensured that all equipment was neatly fitted, cables were tidy, and the site was left spotless; something that matters a lot to our clients.
We installed the Tesla Powerwall 3, which offers an impressive 11.04 kW power output. That’s a significant upgrade compared to previous models and means David can run several high-demand appliances, like his oven, washing machine, and air conditioning, all at the same time without any performance drop.
The system not only meets his current energy needs but is also designed to support additional load in the future, making it a future-proof investment.
What Were the Results?
Since the installation, David has seen a marked drop in his electricity costs. Based on average solar generation and usage, he could save around £800–£1,000 annually on energy bills. With the Powerwall storing daytime energy for use at night, he relies far less on grid electricity, especially during peak-rate hours.
Equally important is the security the backup system provides. In the event of a power cut, the Powerwall automatically kicks in, keeping lights, heating, and essential appliances running without interruption.
The combination of solar panels, battery storage, and an EV charger not only lowers ongoing costs but also increases the property’s market value and sustainability credentials.
After the system was installed, David shared his thoughts with us. Here’s what he had to say:
“Extremely happy with the end result – the installation was extremely neat.”
This kind of feedback drives everything we do. It reminds us why we’re committed to delivering top-quality service and craftsmanship on every job.
