500W JA Solar JAM66S30-500MR BF photovoltaic panel - Black frame, Deep Blue 3.0 monocrystalline, 12 years product warranty, 25 years output power warranty JAM66S30-500MR_BF

The monocrystalline photovoltaic panel from JA Solar is characterized by high efficiency and durability, made using half-cell technology. The half-cell technology is characterized by lower internal resistance and power losses that are 1/4 lower compared to panels based on the classic construction (full cells). Additionally, panels made using half-cell technology, apart from generating higher output power, perform better during everyday operation as a result of a lower power temperature coefficient and reduced impact of shading on energy production.
