The synergies between solar panels and battery energy storage systems: Benefitting the installer and the consumer
Solar panels are currently flooding the European market and it is estimated that there will be as much as 300% growth in solar panels between 2022 and 2026. Manufacturing is becoming more affordable, and this is being reflected in the cost to consumers, and homeowners are keen to move away from using the national grid to save money and live more sustainably.
To really maximise the benefit of solar panels homeowners should integrate battery energy storage. However, to do so, there are several factors that installers need to consider when determining the correct size and type of battery for each project.
There are several directives and standards for an installer to understand, which consider both safety and efficiency.
These directives are much needed catalysts for innovation and investment in the residential industry. Residential developers need to consider renewable energy production and energy storage as well as further technology like heat pumps, and high-quality insulation to adhere to local legislation born out of the European directives. Installers need to offer solutions that minimise grid energy consumption as well as keep homes and their inhabitants safe.
The European Union is consistently developing legislative packages regarding the energy transition and other European states are also acting to support a greener future. Although this blog nods to some key regulations as of 2024, to stay up to date with the latest legislation it is best to check the EU website and national websites.
Whilst adding energy storage or solar generation to your building in isolation is already a great step forward in sustainability and a worthwhile investment, adding both technologies at the same time multiplies the benefits greatly.
Power backup and resilience – More and more consumers are seeking more stable and dependable power sources. The volatility of the energy market has impacted prices in recent years, and with peak time energy consumption increasing, finding an alternative way to power the house than the grid helps consumers to feel in control of their own homes. By storing excess solar power generated on site and redistributing it throughout the day as required, it is possible to significantly reduce one's dependence on the grid. Of course, the degree of independence is reliant on the size of the solar panels, climate conditions and storage system installed, but even a small installation will make a stark difference to a home’s reliance on the grid.
Lower energy costs – With energy independence comes lowered energy costs. Everyone would prefer lower bills at the end of the month, and the act of renewable energy generation and intelligent energy management contributes to this instantly. Lowered bills are a direct result of increased energy independence. In some cases, homeowners can even make money by sending excess energy back to the grid.
Further technological development – Increased independence and energy savings will open new opportunities for advancement. Homeowners may be considering adding electric vehicle charging or other advancements with the newfound capacity that comes with proper energy management. As an installer, deciphering the motivation behind the installation may begin a long-term relationship with the customer that leads to further projects down the line.

Our white paper tackles the integration of battery energy storage and solar in residential buildings, highlighting the importance of safety, efficiency, and compliance with standards.
It also discusses safety strategies and the role of installers in ensuring safe and effective integration of these systems.
When embarking on a green energy transition project, the initial consultations will inevitably be to determine its scale. It is likely the consumer will have some initial desires regarding technology and budgets. However, to gauge what is realistic installers need to know the following:
Pre-existing electrical framework – What is already being used in the home? Perhaps there is a capacity limit on the existing cabling or network. The homeowner may have already invested in some green technology, like solar panels, and so this may make the installation more complex. Understanding the current or anticipated production from solar panels is important, as production differs depending on climate, season, and panel positioning. Installers can keep this complexity lower by opting for pre-wired or prefabricated product designs that keep installation times down.
Availability of space – Depending on the existing electrics, and the size of the home, space can vary dramatically. Homeowners generally prefer to keep energy storage as compact as possible so energy storage options that can be located both inside and outside give installers more flexibility in how they proceed, making upgrades as inobtrusive as possible. In addition to this, Eaton’s xWired configurator tool aids in using existing space optimally, it is a multifaceted web-tool that creates a visualisation of distribution boards and electrical wiring that is document ready and fully compliant.
Eaton products are designed to the highest quality standards to ensure safety. Our xStorage range and associated components are fully compliant with national and European electrical safety standards. In addition, Eaton provides proper training on our products and how to install them safely to enhance your expertise as an installer and give you added confidence on site.
