Solar Trends in Ireland: What to Expect in 2025 & Beyond

Ireland’s solar market has grown rapidly in recent years, with more homeowners and businesses making the switch to renewable energy. Falling costs, generous grants, and increasing demand for sustainable energy have made solar PV a mainstream choice.

But what lies ahead for 2025 and beyond? Here are the key trends shaping the future of solar in Ireland.

1. Continued Growth in Solar Adoption

The number of Irish households installing solar is set to rise significantly. According to SEAI, installations nearly doubled in 2024, and this growth is expected to continue through 2025 as more people realise the savings potential.

Businesses are also investing, with large-scale rooftop and ground-mounted systems becoming more common in commercial and industrial sectors.

2. Bigger Role for Battery Storage

While many homeowners currently install solar without batteries, storage is becoming increasingly attractive. In 2025, expect:

• Falling battery costs – making storage more affordable.
• More hybrid systems – combining solar PV with battery storage for better self-consumption.
• Resilience benefits – backup power during outages, especially important in rural areas.

3. Smart Energy Management

Smart meters and home energy management systems will play a bigger role. These tools allow households and businesses to:

• Monitor energy use in real time.
• Schedule appliances and EV charging during solar production peaks.
• Maximise savings by reducing grid dependence.

The integration of solar, EV chargers, and smart home tech will make energy use more efficient and automated.

4. Stronger Incentives and Policy Support

Government support remains central to Ireland’s solar growth. In 2025, the following policies will shape adoption:

• SEAI grants – €1,800 for residential solar PV systems and up to €162,600 for commercial systems.
• Feed-in Tariffs – households and businesses earning from exporting surplus power.
• Climate Action Plan targets – with Ireland aiming for 8GW of solar capacity by 2030, support for solar will continue to expand.

5. Solar for Businesses and Communities

Community solar projects are gaining ground, especially in rural Ireland, where cooperatives can pool resources to install larger systems.

For businesses, solar is becoming a financial strategy as much as a sustainability move. Expect more companies to install panels to:

• Reduce rising electricity costs.
• Meet ESG and sustainability commitments.
• Power EV charging for employees and fleets.

6. Falling Costs and Higher Efficiency

The cost of solar panels has dropped by over 80% in the last decade, and efficiency continues to improve. New panels in 2025 are expected to:

• Produce more electricity per square metre.
• Last longer with 25–30 year warranties.
• Require minimal maintenance.

This means Irish homeowners and businesses can generate more power from smaller roof spaces than ever before.

7. Solar + EV Charging Integration

With EV adoption in Ireland accelerating, solar-powered EV charging is becoming a major trend. Combining solar PV with home or workplace chargers allows drivers to:

• Charge for free during the day.
• Use excess solar production more effectively.
• Reduce reliance on expensive grid electricity.
