Pairing a solar PV system with a dedicated battery storage unit offers homeowners and businesses the chance to reap significantly greater returns from their renewable energy investments. By capturing surplus solar generation during daylight hours and storing it for use when the sun isn’t shining, battery storage helps to maximise self-consumption, minimise bills and provide crucial backup power during outages. SLC Solutions specialises in advanced battery storage installations designed to work seamlessly alongside your existing—or newly installed—solar array, ensuring you get the very best from every kilowatt-hour generated
What Is Solar + Battery Storage?
A solar PV system alone generates electricity when sunlight falls on its panels, with any excess energy typically exported to the grid under a Feed-in Tariff (FiT) or Smart Export Guarantee (SEG). However, during periods of lower household consumption—such as working hours—much of that generation can be sent back to the grid at rates that are often lower than the price of electricity you pay.
A battery storage system changes that dynamic. Essentially, it comprises one or more rechargeable battery modules, an inverter/charger and a control system. When your solar array produces more power than your property is using, the surplus is routed into the batteries. Then, after sunset or during times of peak electricity pricing, the stored energy can be discharged to power lights, appliances and other devices. This way, you consume more of your own solar energy rather than drawing from the grid, improving overall energy efficiency and cost savings.
How Battery Storage Boosts Solar Efficiency
Maximising Self-Consumption
Without storage, any solar energy you don’t use immediately is exported at the SEG rate, which is commonly a fraction of the import rate. By installing a battery system, you can retain that surplus generation and use it when it’s needed most—typically in the evening or early morning. In practical terms, that might mean charging devices, running heating or powering refrigeration off solar-derived electricity rather than purchasing from the grid, thus reducing the volume of imported power and lowering your energy bills.
Lowering Energy Bills
Electricity tariffs in the UK often vary throughout the day, with peak rates applied during early evening hours when demand is highest. By scheduling the discharge of stored solar energy to coincide with these peak periods, you effectively avoid paying the elevated import rate. Instead, you’re using your own renewable energy at a time when grid electricity would otherwise be at its most costly. Over the course of a year, this shift can lead to substantial savings, especially for households or businesses with significant evening consumption patterns.
Enhanced Overall System Performance
Solar output naturally fluctuates due to changes in sunlight—passing clouds, seasonal variations and shorter winter days can all reduce instantaneous generation. A properly sized battery storage solution helps smooth these variations by storing excess when solar irradiance is high and releasing it when generation dips or demand spikes. The result is a more consistent and predictable energy supply, reducing reliance on the grid and improving the overall efficiency of your renewable setup.
Ensuring Reliable Power Anytime—even During Outages
Backup Power Capability
One of the standout benefits of integrating battery storage is the ability to provide backup power when the grid fails. Should a power cut occur, your battery system can automatically isolate from the grid and continue to supply critical circuits—lights, refrigeration, internet routers and essential medical equipment—ensuring you maintain functionality until grid supply is restored. This resilience is particularly valuable in areas prone to occasional supply interruptions or for businesses where uptime is crucial.
Peace of Mind
Knowing that you have stored energy ready to deploy offers true peace of mind. Even if you’ve never experienced a blackout, the prospect of having lights on and essential appliances running—without resorting to a noisy, polluting generator—can ease concerns over unexpected outages. Especially for vulnerable households (with home medical equipment) or small businesses reliant on constant power, battery-enabled backup ensures continuity at a moment’s notice.
