Customer Challenge
For this homeowner in Bar Hill, Cambridge, the decision to invest in solar and battery storage was less about their current electricity usage and more about planning for the future.
The household was using just under 3,000kWh of electricity per year, so they weren’t among the highest energy users. However, with retirement approaching, the customers wanted to take steps now to future proof their home and reduce their exposure to rising electricity costs.
They were particularly interested in battery storage because of the potential to use cheaper off-peak electricity to help manage their energy costs, particularly during the winter months when solar generation is naturally lower.
A Recommendation from a Happy GLANtech Customer
The customers came to GLANtech Solar through a personal recommendation from another GLANtech customer.
Our existing customer was extremely happy with their own installation and had left us a 5-star Google review, giving the Bar Hill homeowners confidence that they were choosing a local installer they could trust.
For us, referrals like this are particularly rewarding because they demonstrate the importance of providing a high level of service long after the installation itself.
The GLANtech Solar Solution
After discussing the customers’ current electricity usage and their plans for retirement, we designed a system that would provide both solar generation and substantial battery storage without unnecessarily oversizing the solar array.
We installed:
- 8 × Trina 455W Dual Glass solar panels
- 3.64kW solar PV system
- Sigenergy Sigen 10 battery storage system
The 3.64kW solar array provides renewable electricity during daylight hours, helping reduce the amount of electricity purchased from the grid.
The Sigen 10 battery adds another important layer of flexibility. Excess solar generation can be stored for use later, increasing the amount of renewable energy the customers can use themselves.
Importantly, the battery can also be charged using lower-cost off-peak electricity, allowing the customers to take advantage of cheaper electricity when solar generation is limited.
Preparing for Retirement
With retirement approaching, the customers wanted to take a proactive approach to their future energy costs rather than waiting until electricity prices increased further.
The combination of solar and battery storage gives them greater control over when they buy and use electricity.
During the brighter months, solar generation can help power the home and charge the battery. During periods of lower solar generation, particularly through the winter, the battery provides the ability to make use of cheaper off-peak electricity and reduce reliance on higher-cost electricity during the day.
This means the system isn’t simply designed around what the customers use today—it’s designed with their future lifestyle and energy requirements in mind.
The Outcome
The customers now have a modern renewable energy system designed to provide greater energy independence and protection against future energy price increases.
Although their current electricity usage is relatively modest, the Sigen 10 battery provides significant flexibility for managing energy costs as their circumstances change.
Most importantly, the customers have been able to invest in their home’s energy future ahead of retirement, giving them greater control over their electricity usage and the ability to take advantage of cheaper off-peak electricity.
And because they came to us through the recommendation of an existing GLANtech Solar customer, the installation also continues a relationship that started with another happy homeowner in the local area.
