E.ON Solar Panels - Are They Worth It?

Are you considering installing E.ON solar panels and are wondering whether they’re worth it?

E.ON is a well-known energy provider in the UK that offers solar panel installation services. It’s one of the big energy companies obligated to fulfil the Energy Compliance Obligation (ECO) scheme and can allow you to access free solar panel grants if you qualify.

But how do E.ON solar panels compare, and are they worth the investment?

This guide explores everything you need to know about E.ON’s solar panels, including their features, pricing, value, and customer feedback to help you make an informed decision.

Pro tip: Avoid upsells and confusing packages—choose a provider with a clear, fixed-price quote that won’t change. Heatable, a Which?-approved solar installer, offers transparent pricing with no surprises.

What Are the Features of E.ON Solar Panels?

E.ON only installs solar panels from Tier 1 manufacturers to ensure you get some of the best solar panels available.

Tier manufacturers are trusted and established in the solar panel industry and guarantee the highest standards, quality and efficiency.

Solar panel manufacturers become classified as Tier 1 based on a set of criteria typically defined by industry analysts, such as Bloomberg New Energy Finance (BNEF).

Features of E.ON solar panels include:

Efficiency

E.ON solar panels have an efficiency rating of at least 20%. One of their offerings, the JinkoSolar solar panels, feature an efficiency rating of 21.77%.

This makes them a solid choice for homeowners seeking high-efficiency options without venturing into the more expensive, top-tier brands.

E.ON also installs solar panels from JA Solar, one of the largest Tier 1 manufacturers in the world.

The panels feature an efficiency rating of 20.7% and can offer good performance for residential systems.

Premium models can reach up to 22% efficiencies, positioning them as one of the best panels for home installation.

Power Retention and Longevity

Over time, all solar panels experience a gradual decline in power output. E.ON solar panels from JinkoSolar retain around 87.4% of their power output after 30 years.

This is slightly above average and offers a reassuring long-term performance for any homeowner.

E.ON solar panels from JA Solar typically maintain about 84.8% of their initial power after 25 years, which is on the lower side. Some premium panels can maintain this level of performance for up to 30 years.

Warranty

All E.ON solar panels come with a 10-year product warranty, shorter than the industry standard.

Many competitors, including top brands, provide 25 years or more extended warranties, which is becoming the expected minimum. Some manufacturers offer up to 40 years of coverage or more.

E.ON solar panels feature better performance warranties to maintain a specific efficiency level over time. All the panels have a standard 30-year performance guarantee, aligning with typical industry practices.

Pricing and Financial Options

Solar panel pricing can vary based on system size, installation complexity, and specific site conditions. E.ON offers several packages that cater to different needs and budgets:

Package Pricing

E.ON offers two solar packages to help you choose a system that is the most suitable for both your home and your budget.

E.ON’s entry-level, also known as the energise package, is suitable if you don’t have any shading on your roof. It includes a six-panel system (2.61kWp), starting from just £4,995.

You can get better value with the 12-panel system (5.22kWp), which costs around £7,003, making it about 19% cheaper than the average cost for similar-sized systems in the UK.

The optimise package is suitable if your roof has any shading from trees or chimneys. A typical 6-panel (2.61 kWp) system with on-roof solar panels starts from just £6,344 under this package.

Additional Costs

E.ON bases the advertised prices on standard installation scenarios, such as single-story buildings with concrete tiles and no significant access issues.

Additional installation costs on more complex roofs, additional scaffolding, or upgraded electrical systems may apply.

As a result, the final price can be higher depending on the specifics of each installation site.

Finance Options

E.ON offers financing options that make solar panel installation more affordable, allowing you to spread the cost over time.

You can spread the cost of solar panels for up to three years at 0% APR Representative.

You can also pay a deposit and settle the balance once your installation is complete. This would be within seven days of installation and is subject to a credit check.

Government funding is also available, allowing you to get a free solar panel grant depending on your household income and whether you receive a qualifying benefit.

Value for UK Homeowners

E.ON solar panels present a potentially attractive option for UK homeowners looking to cut down on energy bills and embrace renewable energy. Here are some key points to consider regarding their value:

Energy Savings

A typical UK household using a 12-panel system from E.ON can save up to £713 annually on energy bills, especially when using E.ON’s Smart Export Guarantee (SEG) tariff.

This tariff allows homeowners to earn money by exporting excess electricity back to the grid, further enhancing the financial benefits of installing solar panels.

Such savings contribute to a reasonable payback period, generally 10-15 years, depending on energy consumption habits and location.

Environmental Benefits

Switching to solar energy is an excellent way to reduce your carbon footprint. Solar power is a clean, renewable energy source that lowers dependence on fossil fuels, helping mitigate climate change and contributing to the UK’s sustainability goals.

This can be a compelling reason to invest in solar panels if you’re an environmentally conscious homeowner.

Customer Feedback and Reliability

E.ON is rated ‘Great’ on review sites like Trustpilot with a score of 4.0 out of 5. Previous customers have mixed reviews regarding solar panel installations.

Most positive reviews praise the knowledgeable and helpful staff.

The negative reviews complain about the delays in installation, with some customers having to wait for up to 6 months without an installation date, even after paying a deposit.
