Installation Costs Explained

The current market rate for solar panels in Northern Ireland averages £400 per 350W panel. For a typical three-bedroom home requiring a 3.5kWp system, you can expect to pay approximately £4,000 for a complete installation.

Several factors influence your total investment:

  • System size (number of panels required)
  • Panel type (standard panels, integrated panels, or solar tiles)
  • Installation method (roof-mounted systems are most economical)


We recommend obtaining quotes from at least three MCS-accredited installers to ensure you receive competitive pricing and quality service.

Current Grant Situation

Home Solar Panel Grants

While there are currently no direct government grants available for home or residential solar panels in Northern Ireland, the recently published NI Energy Strategy indicates potential future support for renewable energy initiatives.

The Northern Ireland Renewables Obligation scheme closed to new applicants in March 2017, but industry experts anticipate new incentives as part of the region’s commitment to achieving net zero emissions.

Commercial Solar Panel Grants

Invest NI provide expert advice to Northern Ireland businesses to help develop businesses with energy efficiency.

Support includes:

  • Energy Efficiency Capital Grant will offer support to buy and install energy efficient equipment 
  • Resource Efficiency Capital Grant to provide investment support for resource efficient equipment
  • Resource matching service to manage waste and reduce costs
  • Sustainability Reports to assess, measure and monitor environmental impact and performance
  • Technical consultancy for bespoke energy and resource efficiency strategies and recommendation

Managing Excess Energy

Most households typically use 15-25% of the electricity their solar panels generate, depending on:

  • Whether you work from home
  • Number of occupants present during daylight hours
  • If you own an electric vehicle
  • Use of electric heating systems or heat pumps
  • Electric cooking appliances

Many homeowners choose to install battery storage systems alongside their solar panels, allowing excess energy to be stored and used when needed rather than exported to the grid.

Despite common misconceptions, Northern Ireland’s climate is actually well-suited for solar energy generation. Solar photovoltaic (PV) panels convert daylight—not just direct sunlight—into electricity that powers your home appliances and lighting.

For many homeowners in Northern Ireland considering solar panel installation, batteries are indeed worth the investment for several key reasons.

Winter Benefits

One significant advantage of batteries comes during winter months when solar generation is limited. If you’re on a day/night tariff like Click Energy’s Twilight Tariff, you can programme your batteries to charge overnight using cheaper electricity rates, then discharge this stored energy during peak daytime hours when electricity costs are higher. This approach creates meaningful savings even when your panels aren’t generating much power.

Seasonal Strategy

A practical approach is to adjust your battery settings seasonally:

Winter: Charge batteries using cheap night-time electricity, use during expensive daytime hours
Spring/Summer: Switch to charging batteries primarily from solar generation

Many homeowners find it convenient to align these changes with the clock changes in spring and autumn.

Typically 7-12 years, depending on:

  1. System size (3-4kW typical for NI homes)
  2. Installation cost (£4,000-£7,000 for standard systems)
  3. Home energy usage patterns
    Whether batteries are included
Most systems last 25+ years with minimal maintenance, providing 15+ years of effectively free electricity after the payback period.
