About

Generate solar power efficiently with the SAKO 550W Mono PERC Half-Cell PV Panel. Its 144-cell design delivers a module efficiency of 21.30%, making it suitable for residential, commercial and larger solar installations.

The half-cell layout helps reduce connection losses and the effects of partial shading, while its durable glass and aluminium construction is designed to withstand demanding outdoor conditions.

Product Features

• 550W power output: Delivers a rated maximum output of 550 W under standard test conditions.
• High module efficiency: Achieves up to 21.30% efficiency to maximise power generation from the available installation space.
• Half-cell design: Helps reduce internal power losses and limits the effect of partial shading.
• Mono PERC cells: Uses 144 monocrystalline PERC cells for efficient solar energy conversion.
• Weak-light performance: Designed to produce power in lower-light conditions, including cloudy weather, mornings and evenings.
• Anti-PID performance: Helps resist potential-induced degradation for more reliable long-term operation.
• Lower operating temperature: Designed with favourable operating and temperature characteristics to support consistent power output.
• Durable construction: Features tempered glass and an anodised aluminium frame for demanding outdoor environments.
• High load resistance: Withstands front loads of up to 5,400 Pa and rear loads of up to 2,400 Pa.
• Hail impact resistance: Tested to withstand a 25 mm hailstone travelling at 23 m/s.
• Linear performance warranty: Supported by a 25-year linear output guarantee.
