In March 2023, Duncan contacted Cerretti Electrical looking for a long-term solution to rising energy costs at his three-bedroom home. Like many residential homeowners across North East Scotland, he’d seen his gas and electricity bills surge alongside the wider cost of living.
Rather than accept unpredictable monthly bills, he decided to take control.
Here’s how a 3.3kW solar installation with battery storage transformed his energy use, reduced reliance on gas, and gave him real financial confidence.
The Challenge: Rising Energy Bills & Zero Control
Two years ago, when energy prices spiked across the UK, Duncan realised something had to change.
“You faced high bills, you got a monthly bill to pay, and I didn’t have very much control over what was being spent on gas and electric.”
Like many households, the frustration wasn’t just the cost — it was the lack of transparency and control.
He wanted:
- Lower electricity and gas bills
- Protection against future price rises
- Better visibility of energy usage
- A more environmentally responsible home
The Solution: 3.3kW Solar Panel System with Battery Storage
After assessing Duncan’s property, we designed and installed a system tailored to his home’s energy usage.
System Overview
Installation included:
- 10 × Canadian Solar Panels
- 3.3kW solar PV system
- 6.5kW battery storage system
- Solar diverter connected to immersion heater
Expected Generation:
- Approx. 3,000 kWh of clean electricity per year
That’s a significant proportion of a typical three-bedroom home’s annual electricity demand.
Why Battery Storage Matters
The 6.5kW battery allows Duncan to:
- Store excess solar energy generated during the day
- Use stored electricity in the evening
- Reduce reliance on grid electricity
- Maximise return on investment
Even on days with poor weather, stored energy helps smooth out demand and cut costs.
Heating Water with Solar Power (Instead of Gas)
One of the smartest additions to this install was a solar immersion diverter.
This system automatically sends excess solar electricity to heat the home’s hot water cylinder — especially useful in summer months.
“In the summer when the weather’s better, I get hot water from the solar rather than burning gas — which is an environmental and a cost-saving.”
This reduces gas consumption, further lowering overall energy bills.
Performance After 18 Months
Since installation:
- The system has operated reliably
- Only one minor issue occurred (related to the monitoring app, not the system itself)
- Solar generation on sunny days reaches up to 4kW output
On a strong generation day, the system can:
- Heat water
- Boil the kettle
- Run fridge and appliances
- Power daytime household usage
All using free, renewable energy.
The Financial & Environmental Impact
Solar panels don’t just reduce carbon emissions — they create measurable financial benefits.
For Duncan, the biggest change was control.
“With the smart meter and the app for the solar system, I’ve got far more information than I ever had before. I can see consumption, how much it’s costing.”
Benefits include:
- Lower electricity bills
- Reduced gas usage
- Protection from future energy price increases
- Increased energy independence
- Reduced household carbon footprint
Most importantly — predictable costs.
Why Duncan Chose Cerretti Electrical
Duncan didn’t shop around extensively.
He chose us because we’d worked at his home before.
“They come when they say they’re going to come, they do the job, and they leave without leaving a mess.”
For us, that’s exactly how it should be.
Professional. Reliable. No shortcuts.
