When choosing solar panels, homeowners often wonder whether to opt for monocrystalline or polycrystalline panels. Monocrystalline panels are typically more efficient but also more expensive. Polycrystalline panels, on the other hand, offer a good balance between performance and cost. The decision largely depends on your budget and roof space. Both types are widely used in Ireland, but monocrystalline panels are preferred for higher efficiency, especially in areas with limited roof space. Consulting an installer can help you make the best choice for your specific needs.
