You pay more for electricity during the most popular energy use times. Energy rates fluctuate throughout the day. Most people in Britain work from nine to five outside the house, most at-home energy use takes place first thing in the morning or during the evening. Consuming electricity during these times are highest and become a burden for most UK families. From 1 January to 31 March 2026, there will be a small monthly increase of 28 pence on the price of energy for a typical household who use electricity and gas and pay by Direct Debit.
The UK has some of the oldest and less energy-efficient housing in Europe, with rated EPC C or below. It is common to see large families living in draughty, open-plan Victroian conversion with high ceilings, solid walls, and old electric storage heaters. Some families do some of typical evening chores during the middle of the day or later at night to take advantage of the lower rates. Or adjust the thermostat when sleeping or away from home. With high energy prices, larger families are currently affected, leading to difficult choices between heating, eating, and other essentials. Power is such an essential part of modern life, but Is there a way for households to reduce electricity bills without changing their daily habits?
How to reduce your electricity bill?
There is one solution you can take to instantly save your electricity bills while keeping your energy usage. Below, we explore how solar system helps you.
Solar panels work by converting sunlight into electricity, which can then be used to power your home. This reduces the amount of electricity you need to purchase from your grid, ultimately leading to a lower monthly bill. With a properly sized solar system, many homeowners find that their electricity bills are significantly reduced, or in some cases, eliminated entirely. Many people in the UK have the doubt with the solar system performance in winter because sunlight is not enough in winter. Actually, modern, high-efficiency solar panels don't need blazing, direct sunshine. They generate electricity from daylight. Even on a cloudy, overcast day, they are still working, typically producing 10-25% of their maximum output. Sunhome is one of the prior solar installer who provides these kinds of solar panels. Apart from that, Sunhome provides the optimizer. This solar optimizer is a small device installed behind each solar panel that helps the panel produce the maximum possible energy, even when conditions are not perfect.
Product guarantees are necessary to consider when choosing a solar system. Sunhome’s solar panels are 25 years guaranteed and its batteries are 10 years guaranteed. With more than 10 years of expertise in the residential PV sector, we have delivered reliable energy solutions to over 510,000 households worldwide.
