When looking to maximise the value of excess solar energy, two common solutions are battery storage and immersion controllers. Both are designed to make better use of the electricity your system generates, but they do so in very different ways.
A solar battery stores surplus electricity generated during the day for use later on. This means you can power your home in the evening or during periods of low sunlight using your own stored energy, rather than importing electricity from the grid. This flexibility can significantly increase self-consumption and reduce reliance on external energy sources.
Immersion controllers take a more targeted approach by diverting excess solar energy to heat your hot water. Instead of exporting unused electricity, the system automatically redirects it to your immersion heater. This can reduce or even eliminate the need for gas or electric water heating, depending on your setup.
Battery storage typically offers broader savings, as it reduces the amount of electricity you need to purchase from the grid across your entire home. However, this comes with a higher upfront cost. Immersion controllers are more affordable and can deliver immediate savings, particularly for households with consistent hot water demand.
The most suitable option depends on how your household uses energy. Homes with higher evening electricity consumption may benefit more from battery storage, while those with significant hot water usage may see better value from an immersion controller. In some cases, a combination of both can provide the most balanced outcome.
Both technologies play an important role in improving solar efficiency. Choosing the right solution ensures you capture more of the energy you generate and maximise the overall return on your system.
