Ultimately, the cost of a solar diverter is subject to various factors, including the brand, model, features, and installation specifications. We strongly recommend reaching out to a local solar installation company or supplier for an accurate cost estimate tailored to your specific needs.

It’s essential to factor in installation expenses into your budget, as these costs may vary based on the complexity of the installation, the existing electrical setup, and any additional components or accessories required.

As solar panels gain popularity, an expanding range of manufacturers is introducing their products to the market. Consequently, we anticipate a gradual decrease in diverter costs as pricing becomes more competitive.

When do you break even on a solar diverter?

Solar diverters frequently demonstrate a return on investment within a short span of two years. The efficient utilization of solar energy varies considerably in each situation. Nonetheless, for most users, maximizing savings and expediting the payback period for the diverter usually entails harnessing surplus electricity generated within their own household.

How is a solar diverter installed?

As an example, concerning the provision of hot water, the solar diverter, a compact electronic device, is positioned between the electrical supply switches of your boiler and the immersion heater, which serves as a backup in the event of gas failure.

Upon activation of the immersion heater switch, it supplies power to the solar diverter, while the immersion heater itself remains dormant. The solar diverter is equipped to monitor the solar panels, identifying any surplus energy. This extra energy is subsequently directed to the immersion heater to heat the water.

Sophisticated models like the Eddi can synchronize via an internet connection with other products, such as Zappi, an electric vehicle charger also manufactured by MyEnergi, enabling the maximization of self-generated solar power.

It is crucial that any solar diverter installation is conducted by a certified electrician or a professional solar installer to ensure compliance with safety regulations.

Are solar diverters worth it?

If you are currently enrolled in the government’s initial feed-in tariff program, using a solar diverter remains a viable option.

Solar diverters do not impact solar panel systems under the feed-in tariff. The tariff compensates for 50% of the energy your system produces, ensuring consistent payment whether you export surplus energy to the grid or divert it for heating hot water.

This approach helps optimize your energy savings and ensures maximum efficiency from your solar panels.

The Smart Export Guarantee, which was introduced by government in 2020 following the closure of the feed-in tariff in 2019, lets energy suppliers decide what tariffs to offer their customers.

Given the current elevated export rates in the UK, with providers like Octopus Energy offering 15p per kilowatt-hour (kWh) and Scottish Power offering 12p per kWh, it is probable that you would derive greater financial benefit by exporting your surplus energy to the grid rather than using a diverter.

As highlighted earlier, the actual value of your solar power exceeds these rates, but it is still advantageous to generate income from it rather than not utilizing it at all.

Do solar diverters require any maintenance?

Solar diverters generally require minimal maintenance; however, periodic inspections are crucial to ensure cleanliness, freedom from debris, and absence of damage.

Some solar diverters may provide firmware updates, which can be facilitated by the manufacturer. It’s important to check for available updates and follow the provided instructions to keep the unit updated.

In case of issues or a decline in the diverter’s performance, seeking guidance from the original installer or the manufacturer’s support team may be necessary.

Next steps  

Knowing how to optimize your solar panel investment is vital, especially during times of increased bills due to a cost-of-living crisis.

Several factors impact the decision on whether a solar diverter is suitable for your needs, especially for those under the Smart Energy Guarantee. We recommend seeking advice from a professional if you are uncertain.

Before delving into solar panel diverters, it’s essential to assess the solar panel system itself.
