For many UK homeowners, solar panels are seen as a “daylight-only” benefit. However, in 2026, the real magic happens after the sun goes down. By pairing a solar system with a Home Battery Solution, you aren’t just capturing the sun; you are gaining the ability to play the energy market to your advantage using “time-of-use” tariffs like Economy 7.
What is the Night Shift?
Economy 7 tariffs provide a window of significantly cheaper electricity—often between midnight and 7 AM. Traditionally, this was used for storage heaters. Today, smart inverters allow you to “force-charge” your home battery from the grid during these off-peak hours.
During the winter, when solar generation is naturally lower, your battery can act as a reservoir for this cheap grid power. You wake up at 7 AM with a full battery that cost you a fraction of the standard rate, allowing you to power your morning shower, kettle, and breakfast without touching expensive daytime electricity.
Year-Round Financial Protection
The beauty of this strategy is that it removes the seasonal “dip” in solar value. While your panels do the heavy lifting in the summer, the Economy 7 integration ensures your system is working for you 365 days a year.
- Summer: Your battery is filled for free by the sun.
- Winter: Your battery is filled cheaply by the grid at night.
By utilizing this “Night Shift” approach, customers can see a drastic reduction in their average unit cost per kWh.
