At SolarTherm UK, we’re always looking for ways to help our customers make the most from their solar panels and save even more money. One popular add-on is a solar diverter. A clever device that ensures no free solar is going to waste. But are they worth the investment? Let’s have a look…
What is a Solar Diverter?
A solar diverter is used to work alongside your solar panels and help you use more of the electricity you are generating. Instead of sending excess energy back to the grid, a diverter redirects the surplus into a specific appliance, most commonly your immersion heater to provide hot water. It can also be used with electric heaters, EV chargers and other compatible devices.
How Much Does a Solar Diverter Cost?
Solar diverters typically cost £300-£500 plus installation. Popular brands include the Solar iBoost, MyEnergi Eddi and SolarEdge Diverter. Contact SolarTherm UK today for a clear, transparent quote including the return on investment which is typically just two to three years for a solar diverter. If you are on the Feed-in Tariff (FiT) a diverter is particularly beneficial as you’re still receive payment for the excess energy and use more of it yourself. If you are on a higher rate of the Smart Export Guarantee (SEG) exporting may be more profitable, especially if your SEG rate is high and you have a low off-peak rate.
Pros and Cons of Solar Diverters
Pros
- Makes the most of the generated electricity
- Cuts down further on energy bills
- Reduces your carbon footprint with greener energy
- Doesn’t affect your FiT payments if you receive them
Cons
- Additional upfront cost of diverter and installation
- Not compatible with combi boiler systems for hot water heating
- Shorter lifespan than solar panels of around 10 years
So, Are Solar Diverters Worth It?
For many households, yes. If you’re on the FiT, a diverter is an excellent way to maximise your investment. If you’re on the SEG, it comes down to the numbers, your export rate versus your energy usage. Households with a high demand on hot water or high daytime energy consumption tend to see the biggest benefits.
