In stock
The panel is rated at 580W maximum power, delivered at a 13.62A maximum power current.
Open circuit voltage is 51.47V and short circuit current 14.37A, protected by a 30A maximum series fuse.
Pmax falls only -0.29% / °C as the module heats, while Voc moves -0.25% / °C and Isc rises +0.045% / °C.
Heat strengthened coated glass of 2.0mm at the front and 2.0mm heat strengthened glass at the back sit in an anodized aluminium alloy frame.
The module carries 5400Pa of static load on the front face and 2400Pa on the rear face.
Each module weighs 31 kg at 1134 x 2278 x 30 mm and works up to a DC1500V (IEC) system voltage under Class II protection.
The Felicity Solar GK-1-72HTBD-580M is a 580W solar panel built as a glass-glass laminate: 2.0mm heat strengthened coated glass at the front, 2.0mm heat strengthened glass at the back, held in an anodized aluminium alloy frame. It measures 1134 x 2278 x 30 mm, weighs 31 kg and is rated for a DC1500V (IEC) maximum system voltage. Electrically it delivers 580W at 13.62A maximum power current, opens at 51.47V Voc and short-circuits at 14.37A Isc, so string design has to allow a 30A maximum series fuse. Heat is where the module earns its place: Pmax falls only -0.29% / °C, Voc moves -0.25% / °C and Isc rises +0.045% / °C, against a stated operating temperature of 45 ± 2°C. The structure takes 5400Pa of static load on the front face and 2400Pa on the rear, and Class II protection covers the wiring, which arrives as TÜV 1x4mm² output cables 300mm long on the positive and 200mm on the negative, customisable on request. Certified to CE, IEC 61215(2021), IEC 61730(2023) and PID. We are the authorised Felicity Solar distributor and supply the panel with a 2 Years warranty.

580W is the rated maximum power, delivered at a 13.62A maximum power current. Open circuit voltage is 51.47V and short circuit current 14.37A, so string sizing must respect the DC1500V (IEC) maximum system voltage and a 30A maximum series fuse.
-0.29% / °C is the Pmax temperature coefficient, so output falls slowly as the module warms. Voc moves -0.25% / °C and Isc rises +0.045% / °C, against a stated operating temperature of 45 ± 2°C.
2.0mm heat strengthened coated glass at the front and 2.0mm heat strengthened glass at the back sit in an anodized aluminium alloy frame. The module measures 1134 x 2278 x 30 mm, weighs 31 kg and withstands 5400Pa on the front face and 2400Pa on the rear.
CE, IEC 61215(2021), IEC 61730(2023) and PID are the certifications on this module, alongside Class II protection and TÜV 1x4mm² output cables measuring 300mm on the positive and 200mm on the negative. We are the authorised Felicity Solar distributor and supply it with a 2 Years warranty.
