Why should I invest in solar energy?
Lowers your
energy bills
With such sharp rises in energy bills in recent years, the biggest individual benefit of solar panels is the reduction in your monthly energy bills.
Reduces your carbon footprint
Solar energy is a clean and renewable source of power. Unlike some other forms of power, it does not emit harmful greenhouse gases.
Adds value to
your property
Homes equipped with solar panels tend to have higher resale values. In fact, research states that homes with solar panels sell for 25% more than those without.
Requires low maintenance
Solar panels generally require low maintenance, with only occasional cleaning and inspections required to ensure they continue to work efficiently.
Make money by selling back
Any unused electricity can be sold back to the grid, earning you money. The amount you get from selling back to the grid will depend on your energy supplier.

Frequently asked questions
Yes, solar panels are worth the investment. Not only do they reduce your impact on the planet by reducing your carbon footprint, but they also help to save you money on your energy bills. In fact, it is estimated that installing solar panels can help you save between £400 and £915 every year on your electricity bills.
The cost of installing solar panels depends on your property, energy requirements, and what kind of system you install. As all our installs are bespoke to both the home and customer’s requirements, no two installs are the same. If you are looking to move to solar, get in touch with us for a no-obligation quote.
How many solar panels you will need to run a house depends on a number of things, such as your electricity usage and the size of your property. However, a typical three-bedroom house usually needs around 10 solar panels to run on solar.
Yes, solar panels do work in the winter, and throughout the year. In fact, solar panels can even generate power in light snow. However, solar panels generally produce less energy in the winter due to the number of daylight hours being reduced and the sun being lower in the sky than during other times of the year.
In most cases, solar panels that are mounted on the roof of a domestic property do not require planning permission. This is because they usually fall under what is referred to as permitted development rights which is where homeowners are allowed to improve and extend their homes without the need to apply for planning permission. However, there may be cases where you do require permission, such as on listed buildings and in conservation areas.
Whether you should invest in a battery when installing solar panels depends on your usage and expectations for your solar panels. But in general, installing a battery alongside your solar panels can save you money in the long run by enabling you to use more of the electricity your solar panels produce. For example, a home without a battery installed will typically use around 30-50% of the energy it generates, while those with a battery installed will typically use between 70-90% of the solar electricity generated.
Yes, you need to tell your electricity supplier when you get solar panels installed. This is so they can manage the electricity flow effectively and provide you with accurate bills.
There are grants available for solar panel installations, but not everyone will be eligible. The two grants are the ECO4 grant and the Warm Homes Nest Scheme (only available in Wales). Both offer grants covering up to 100% of the installation costs for households on low incomes.
