A Step-by-Step Guide to Rewiring Your Home
Are your energy bills still climbing? You’re not alone. With UK households now paying around £1,690 a year on average for electricity according to Ofgem, finding smarter ways to cut costs is essential. That’s where solar panels and battery storage come in. By generating and storing your own power, you reduce reliance on the grid and protect yourself from future price hikes.
In this guide, we’ll break down how solar panels save money, explain solar and battery storage costs, and show how Mission Road Electrical delivers expert, cost-effective solutions that put you in control of your energy spend.
When sunlight hits a solar panel, it gets converted into electricity – simple as that. That electricity is then used to power your home or business. Any energy you don’t use right away typically gets sent back to the grid, unless you have a battery (we’ll get to that in the next section).
So, how much can solar panels really help? A typical domestic solar PV installation can cover 40% to 60% of a household’s annual electricity usage, depending on factors like roof orientation, system size, and usage patterns. In commercial settings, the impact can be even greater due to high daytime consumption.
Here’s why solar PV installation can lead to serious savings:
Whether you’re a homeowner or managing a commercial property, installing solar makes financial sense – especially when paired with battery storage.
Without battery storage, any electricity your solar panels generate but don’t immediately use is typically sent back to the grid. While some schemes pay you for this, the rate is often far lower than what you pay to buy electricity later – battery storage changes the game.
By storing excess daytime energy for evening or overnight use, a battery reduces your reliance on the grid during peak times. That means you avoid paying top rates when demand is high, and you don’t have to draw power from the grid once the sun goes down.
For many properties, especially those with evening-heavy usage, battery systems significantly increase the self-consumption rate. This boosts your energy independence and enhances the value of your commercial or domestic solar installation.
Put simply, battery storage makes every unit of solar energy go further – and that’s key to how solar panels save money.
Let’s get into the numbers. For homeowners, annual savings from solar PV and battery storage systems typically range from £400 to £800, depending on system size and usage. Businesses with larger systems can save £1,500 to £5,000 or more per year.
But it’s not just about short-term savings. The average payback period for a well-sized solar and battery setup is around 6 to 10 years, after which you’re essentially generating free electricity for the remainder of the system’s 20–25-year lifespan. That’s a strong solar panels return on investment, especially when combined with rising grid prices.
Bear in mind:
All of this helps significantly reduce energy bills with solar, while also improving your long-term financial stability.
Commercial properties – especially schools, office buildings, and landlord-managed blocks – stand to benefit the most from solar PV and battery systems.
Here’s why:
At Mission Road, we’ve supported multiple landlords and educational institutions with tailored solar PV solutions that meet their building’s energy profile, regulatory requirements, and sustainability goals.
Don’t just take our word for it – the Energy Saving Trust has detailed how commercial installations are cutting costs and reducing emissions, as highlighted in one of their case studies.
If you manage multiple sites or oversee public sector budgets, investing in domestic or commercial solar energy solutions is one of the most effective ways to take control of long-term utility costs.
