Gary’s Case Study

“The whole family is now using energy in a far smarter way.”

Being given a chance to test the latest renewable technologies first hand and to see if they could reduce their carbon footprint, was an appealing prospect for Gary and his family.

Gary and his three children live in West Berkshire, in a four-bedroom, detached home. Constructed in the early 1990’s, the family’s monthly energy bills typically average around £90 for both gas and electricity.

The family agreed to take part in a trial being run by Anesco, to assess how different measures perform in a real-life setting and to gain insights that can be used to enhance the overall customer experience.

The design and installation process

The process began with a detailed assessment of current energy use with a smart metering system fitted to the property. The family also provided copies of recent energy bills.

After looking into the feasibility of different measures and what would be most suitable for the property and the family’s energy needs, it was agreed that a rooftop solar scheme and energy storage unit would be installed.

The team at Anesco then got to work surveying the property and designing the solar scheme to ensure it was placed in the optimal position and would therefore generate the maximum amount of energy. Rather than the house, it was found that the garage roof would provide the best location.

While the solar panels were being installed externally, the energy storage unit was simultaneously fitted internally, within the utility room. The whole installation was completed in under four days and now in place, the systems will continue to run with little or no maintenance, for years to come.

Technologies installed

Smart metering system – Loop meters fitted within the property to monitor energy use. The data can be accessed via an app, giving the family complete visibility of what’s happening.

Rooftop solar – 3.3kW solar PV system installed on the garage roof. The panels convert sunlight into electricity that can be used to power appliances within the property.

Energy storage unit – 5kWh Sonnen battery storage unit installed in the utility room. The unit stores any surplus energy generated by the solar panels, so it can be used when the family needs, such as in the evenings. The battery also charges from the grid at off peak times when rates are low, and discharges energy back into the grid at peak times, providing further financial benefits.

Smart switching – an auto-switching subscription was set up to continually keep the household on the best tariff for the new system. This has saved money even though the family regularly switched supplier beforehand.

The whole family is now using energy in a far smarter way

The family’s annual energy bills are now on track to reduce by around 50% but the impact has been far greater than simply financial.

Gary commented: “Having access to data about how much energy the solar panels are generating, how much power the battery has stored and how much electricity each appliance is using, has completely transformed our habits – and it’s just happened naturally.

“The whole family is now using energy in a far smarter way. For example, if we know it’s going to be sunny at lunchtime when we’re out, then we’ll set the timers on our appliances to coincide with this. The solar panels then start generating electricity, which is used for the appliances and any energy they don’t use is stored in the battery for us to use later. It’s a far more efficient way of using energy and ensures nothing is ever wasted. Good for us and good for the environment.”

“We’re all really interested in the data and when I get home, looking at how much energy the battery has stored is one of the first things I do! I love being able to login to the app too and it’s especially great to see the kids so interested and to be educating them on these issues.”
