Manx Utilities is developing utility scale solar projects that supply electricity directly into the Island’s power system. These projects form part of a broader programme to diversify electricity generation, improve energy security and support the Isle of Man’s long term energy strategy.

Utility scale solar differs from domestic rooftop installations as it feeds electricity straight into the public power system rather than serving a single property.

Solar panels use photovoltaic cells to convert sunlight into electricity. When sunlight hits the panels, it creates an electrical current, which is then converted into a form that can be used by the power system.

Solar panels generate renewable electricity that can reduce reliance on fossil fuels. At a utility scale, solar contributes to the Island’s overall electricity supply and supports progress towards lower carbon generation.

Solar generation varies depending on daylight and weather conditions, so it operates alongside other generation sources rather than replacing them entirely.

The amount of electricity generated depends on panel size, location and sunlight levels. Due to local weather conditions, solar panels on the Isle of Man typically operate at a lower average output than in sunnier regions.

While individual panels produce relatively small amounts of electricity, larger installations can collectively make a meaningful contribution to the power system over the year.

Solar projects can:

• Contribute to lower carbon electricity generation
• Improve energy security by diversifying power sources
• Provide locally generated electricity to the Island’s power system

They are one part of a balanced mix of generation technologies needed to maintain a reliable electricity supply.

Solar power produces electricity without direct carbon emissions during operation. By generating renewable electricity locally, solar can reduce the amount of fossil fuel generation required over time.

However, solar output varies throughout the day and year, so it must be supported by other generation and storage solutions.

Solar technology has been in use since the mid‑20th century and was initially developed for space applications. Over recent decades, improvements in efficiency and manufacturing have led to wider adoption worldwide, including utility scale projects.

Permission requirements depend on the type and location of the installation:

• Rooftop installations may not require planning permission if they meet permitted development criteria
• Ground mounted solar projects require planning approval

All solar installations connected to the public power system also require a Consent Order.

Installation times vary depending on the size and location of the project. Utility scale installations typically take several weeks to months from construction start to completion.

The cost of solar installations varies by size and design. Maintenance requirements are relatively low and usually involve routine inspections and occasional cleaning to ensure safe and efficient operation.

Solar panels typically operate for 25–30 years, with gradual reductions in performance over time. They are designed for long term outdoor use.

Solar panels and associated equipment can be recycled. Many materials used in panels can be recovered and reused, reducing waste at the end of their operational life.

Panels are mounted on supporting structures, either on rooftops or on the ground. The electricity generated is routed through electrical equipment that connects safely into the power system.

If a panel fails or is damaged, it can be replaced by qualified technicians without affecting the rest of the installation.

Yes. Solar installations are designed, manufactured and installed in accordance with established safety standards and are widely used internationally as a safe method of electricity generation.

Manufacturing solar panels involves material extraction and energy use. These impacts are typically offset within a few years of operation through the production of low carbon electricity.

Manx Utilities considers environmental factors as part of project development, including land use and biodiversity.

• Rooftop solar generally has minimal visual impact
• Ground mounted solar can be more visible, particularly in open areas

Design measures such as layout, screening and landscaping can be used to reduce visual impact and support biodiversity.

Solar panels generate electricity that is converted and fed into the public power system through dedicated electrical equipment, allowing it to be used alongside other sources of generation.
