Case Study: Solar Panel & Battery Installation – A Journey to Energy Independence and Cost Savings

Introduction

With rising energy costs and environmental concerns, homeowners are increasingly seeking sustainable energy solutions. This case study illustrates the journey of a homeowner who installed a 7.14 kW solar panel system and a 12 kW battery. Utilising high-quality FOX ESS and JA Solar components, this system aimed to maximise self-sufficiency and cost savings by reducing grid dependency, optimising energy storage, and generating revenue through surplus energy sales.

Problem

The homeowner faced high energy expenses averaging £136 per month during the first quarter of 2024. With annual increases in energy prices, these costs represented a growing financial strain and led the homeowner to seek ways to reduce their energy expenses and environmental impact. The goal was clear: to lower dependency on grid power, save on energy costs, and make a positive environmental impact by adopting a more sustainable lifestyle.

Solution

The solution involved installing a 7.14 kW solar panel array coupled with a 12 kW battery system. Key features of this system include:

– Sleek Design: The modern, streamlined appearance of the setup blended well with the home’s aesthetics, enhancing curb appeal while delivering high energy performance.

Energy Independence: The system reduces reliance on grid energy, promoting a self-sustaining energy cycle

Eco-Green Payoff: Environmental impact through reduced carbon emissions and sustainable energy sourcing.

– Energy Generation: Solar panels powered the household during the day, with surplus energy stored in the battery for nighttime or cloudy day use.

– App-Controlled Energy Management: Through an intuitive app, the homeowner managed energy flow, storing or selling energy based on real-time usage and grid pricing.

– Smart Export Guarantee (SEG): Excess energy not needed for immediate or later use was exported to the grid, generating income through SEG, an incentive that pays homeowners for surplus energy fed back to the grid.

– Flexible Charging Options: The system allowed the homeowner to charge the battery from the grid during off-peak hours, making it possible to buy cheaper energy and store it for later use, especially when solar generation was insufficient.

Results

The results following the installation were substantial, illustrating not only monthly energy savings but also additional revenue generated through SEG.

1. Dramatic Cost Reductions

   – Before Installation: From January to April 2024, the homeowner incurred an average monthly energy cost of £136, totalling £544 over four months.

   – After Installation: Post-installation, monthly energy expenses dropped significantly to an average of £9.78 per month, reducing the total energy cost from May to October to £39.12, representing a dramatic shift in monthly outgoings.

2. Monthly Savings

   – Six-Month Overview: The system’s installation reduced the homeowner’s monthly energy cost to approximately £20, representing a consistent average saving of £116 per month.

   – Total Savings: Over six months, this translated to a cumulative saving of £696, nearly covering the expected grid-dependent expenses for the same period if the system had not been installed.

3. Revenue from SEG

   – By exporting surplus energy back to the grid, the homeowner earned £484.65 in SEG payments over the six-month period. Combined with savings on bills, this resulted in a monthly financial improvement of £195.95.

   – Net Gain: The total financial benefit was £1,175.70 over the first six months, combining both SEG earnings and energy bill reductions.

4. Environmental Impact

  – The installation promoted sustainable energy usage by lowering carbon emissions and reducing dependency on non-renewable energy sources. By generating clean, renewable energy on-site, the homeowner contributed positively to the environment while enjoying self-sufficiency.

Conclusion

This case study demonstrates how a strategic investment in solar and battery technology can yield both financial and environmental benefits. By reducing reliance on grid electricity and optimising energy use, the homeowner achieved significant monthly savings and generated income through energy export, all while contributing to a greener future. This one-time investment promises ongoing savings, resilience, and an eco-friendly footprint, proving that transitioning to renewable energy is both a financially sound and sustainable choice.
