Energy: The Issues
Households across the UK have always been keen to explore options for tackling rising energy prices, and in 2011 the popularity of domestic solar panels started climbing. Despite being new technology, the promise of turning your property into your own power plant was big appeal, and at the time the UK Government climbed aboard, offering incentives that made solar panel installation a worthy investment.
Fast-forward through the years and as technology improved the efficiency increased, however not all was good news as the government incentives deminished and the real issues became more and more prevelant. Solar panels are only as good as the amount of sunlight they receive, and the correlation between electricity production and usage needs to balance for them to be worthwhile.
Fast-forward through the years and as technology improved the efficiency increased, however not all was good news as the government incentives deminished and the real issues became more and more prevelant. Solar panels are only as good as the amount of sunlight they receive, and the correlation between electricity production and usage needs to balance for them to be worthwhile.
Household electricity requirements & solar panel electricity production by hour
In 2022, the UK received less sunlight than 89% of European countires, equating to half the total sunlight of Spain, Portugal and Greece, and studies show that the times the solar panels produce the most energy are the times that the average UK household is using the least energy, resulting in significant wastage.
In a typical household 71% of our daily electricity needs are between 6am - 8am and 3pm - 8pm, yet solar panels produce 89% of their electricity outside of these hours

Energy: The Solution
Across the UK average household demand for electricity follows a reliable pattern, where 92% of daily demand falls between the hours of 6am and 10pm. Naturally, energy suppliers have capitalised on this demand pattern by charging higher prices per kWh when demand is great, but also offering cheaper prices in periods of low demand, such as through the night.
The latest deals show some energy suppliers reduce energy costs by as much as 75% during periods of low demand. Unfortunatley, the vast majority of households are currently unable to make use of electricity whilst it's cheap without significant lifetsyle compromise.
