Ireland’s temperate climate and strong winds make it a prime candidate for renewable energy, but choosing between solar PV panels and micro-wind turbines depends on location, budget, and energy goals. Solar panels thrive in south-facing, unshaded roofs, with an average Irish home generating 2,500–4,000 kWh/year from a 4kW system. Even with cloudy skies, modern panels operate at 15–20% efficiency.
Wind turbines, meanwhile, require consistent 4.5m/s+ winds to be viable. Urban areas often lack this due to turbulence from buildings, making rural sites better suited. A 5kW turbine can produce 8,000–12,000 kWh/year in ideal conditions—but noise regulations and planning permissions add hurdles.
Battery storage is critical for maximizing self-consumption. Solar pairs well with lithium-ion batteries (e.g., Tesla Powerwall), storing excess daytime energy for night use. Wind’s intermittent nature demands larger battery banks, increasing upfront costs. The SEAI grants (up to €2,400 for solar, €1,800 for wind) help offset these expenses.
Maintenance is another differentiator. Solar panels need annual cleaning and inverter checks (lifespan: 25+ years). Wind turbines require bi-annual bearing inspections and are prone to storm damage. For most Irish households, solar offers a simpler, more predictable ROI—but wind can excel in exposed western counties like Clare or Galway.
