Go Further with Solar: Batteries, Hot Water Diverters, and Smart Add-ons
Already got solar panels? Or thinking about them? These upgrades can help you get even more value—saving money, using more of your own energy, and future-proofing your home.
Do I need a solar battery?
No—but having one can dramatically increase your solar savings. Without a battery, most households use only 30–40% of the energy their panels generate. The rest goes back to the grid. A battery lets you store surplus energy during the day and use it at night—boosting your self-consumption to over 80%.
Cost? Expect £3,000–£7,000 depending on size and type.
Payback? Usually 8–12 years, faster if you’re a high user or on time-of-use tariffs.
What’s a hot water diverter?
Simple but clever: it redirects your surplus solar power into your immersion heater. Brands like Solar iBoost and Eddi heat your water for free—so your gas or electricity bill drops even further.
No moving parts, no maintenance, and payback in just a few years. It’s one of the most cost-effective add-ons available.
Smart usage = smart savings
Using energy when the sun is shining is key.
Tip: Set your dishwasher, washing machine, or EV to run midday—not at night. Smart plugs and home energy monitors can automate this for you.
The more you shift usage to the sunniest hours, the less energy you buy.
Already have solar? Here’s how to upgrade
- Add a battery: Easily retrofitted to most systems.
- Install a diverter: Even older systems can benefit.
- Go smart: Consider smart meters, usage trackers, and load controllers.
- Think bigger: Add panels, or combine with heat pumps or EV chargers.
Bottom line: Going solar is a great first step. But going further—smartly—is how you unlock serious savings, energy independence, and resilience for the future.
