How the Clock Changing Affects Solar Energy in the UK

Twice a year, the UK adjusts its clocks for daylight saving time, moving an hour forward in spring and back in autumn. While this shift is designed to optimise daylight hours, it also impacts solar energy efficiency and output across the country. Is your solar system optimised, ready and monitored?

The Impact of the Spring Forward

When the clocks move forward in March, the evenings stay lighter for longer, benefiting solar panel owners. Although the total daylight hours remain unchanged, the shift means solar energy production better aligns with household energy consumption. This allows homeowners to make the most of their self-generated solar power in the evening, reducing reliance on the national grid. Those with battery storage can maximise energy efficiency by storing surplus power during peak sunlight hours for later use.

The Effect of the Autumn Clock Change

In October, when the clocks return, solar panels still generate the same total energy, but peak generation occurs earlier in the day. With shorter evenings and earlier sunsets, homeowners may rely more on grid electricity unless they have battery storage to capture excess daytime energy. A solar monitoring system can help track energy production and consumption in real-time, enabling homeowners to optimise their usage and store energy more effectively.

Maximising Solar Energy Efficiency All Year Round

Regardless of the clock changes, homeowners can optimise solar energy efficiency by implementing these strategies:

• Install a Battery Storage System: Store surplus solar energy during the day for evening use, reducing reliance on the grid.

• Adjust Energy Consumption Habits: Use high-energy appliances, such as washing machines and dishwashers, during peak sunlight hours.

• Regular System Maintenance: Keep solar panels clean and well-maintained to ensure maximum efficiency.

• Smart Home Integration: Implement automated systems to optimise energy usage based on solar availability.

• Use a Solar Monitoring System: Track energy production and consumption in real-time to maximise efficiency and identify performance issues early.

Conclusion

The UK’s biannual clock changes influence solar energy usage patterns, although the total amount of solar power generated remains consistent. By adapting to these shifts with strategic energy management, homeowners can maximise their solar energy efficiency, lower electricity bills, and reduce their carbon footprint. Investing in battery storage, solar monitoring systems, and smart technology ensures the benefits of solar power are optimised all year round.
