The LONGi Solar 470W panel is one of the highest-output residential panels from LONGi, ideal for Irish homes where roof space is limited but homeowners want maximum electricity generation.

Designed to perform exceptionally well in Ireland’s cloudy climate and withstand strong Atlantic winds, the 470W panel is a top choice for coastal and inland properties alike.

Installers often recommend it for larger homes, SEAI grant installations, and homeowners seeking long-term energy savings.

Key Specifications

This high-output panel is part of LONGi’s Hi-MO series, designed for maximum residential efficiency.

Performance in Irish Weather

Low-Light and Cloudy Day Performance

Ireland often has diffuse sunlight rather than full sun, especially during winter and overcast months. The LONGi 470W panel maintains strong efficiency in these conditions, generating more electricity per panel than the 460W model.

Wind and Storm Resistance

Irish coastal areas experience powerful winds and Atlantic storms. The LONGi 470W panel is engineered for high wind loads, making it suitable for homes in Galway, Cork, or Dublin coastal suburbs. Proper installation ensures long-term durability and minimal maintenance.

Winter Energy Output

The panel’s higher wattage helps offset shorter winter days, delivering more electricity during low-light months than smaller panels.
