450W All Black Half Cut Monocrystalline Solar Panel | Voltacon

The Voltacon 450W all black solar panel uses half cut PERC monocrystalline cell technology, giving reliable output with improved shading tolerance and reduced wire losses. The black anodised frame and back sheet suit residential roofs and commercial installs where appearance matters as much as performance.

• Frame and back sheet, all black anodised aluminium
• Junction box, IP67 with 4mm² MC4-compatible cables
• Warranty, 15-year product warranty, 25-year performance warranty

Product overview

Half cut cell technology splits each cell into two halves, cutting the current through each section and lowering resistive losses in the wiring. Two independent bypass sections mean shading on one half of the panel does not suppress output from the other half, which helps real-world yield on partially shaded roofs.

The black anodised frame and black back sheet give a uniform look on dark roof tiles, a common choice where the visual impact of the array matters.

Applications

• Residential rooftop solar PV systems
• Commercial rooftop installations requiring a black aesthetic
• Ground-mounted and flat roof solar arrays
• On-grid and off-grid systems requiring high-efficiency compact panels

Installation and safety notes

This panel must be installed by a qualified MCS-accredited solar installer. Mounting structure design, string voltage calculations, cable sizing and earthing must comply with IET Wiring Regulations and the panel installation manual. Do not exceed the maximum system voltage of 1000VDC or the maximum series fuse rating of 20A.
