Sino Green SG420J BP SX20U 20W Solar Panel

Sino Green SG420J BP SX20U 20W Solar Panel

The SG420J 20 Watt solar panel is part of Sino Green's rugged industrial off grid series. 

These high quality solar modules provide cost-effective photovoltaic power for DC battery charging systems. 

With 36 monocrystalline cells in series, this panel charges batteries efficiently in any climate.

The SG420J is a BP SX solar panel replacement intended for 12VDC solar battery charging systems (charge controller required). 

It may be wired in series for higher nominal voltages. It is ideal for longevity outdoors; with an anodized aluminum frame and tempered glass face.

The SG420J is approved for applications in NEC Class 1, Division 2 Groups A, B, C & D hazardous locations and approved for explosion resistance. 

This certification is required near gas and oil pipelines.

The SG420J is Built to Last

From mountaintops to vast oil fields, on weather stations in the bitter cold of Antarctica and on telephone signal repeaters 

in the hot Australian outback, the technology behind these reliable solar panels has been proven in the harshest environments.

The SG420J has has a weatherproof junction box and a very rugged frame. The standard terminals accept 8 AWG to 14 AWG wire. 

The raintight (IP65 Rated) junction box of the SG420J accepts PG13.5 or 1/2" nominal conduit or cable fittings. 

With its four-terminal connection block, it enables most system array connections (putting modules in series or parallel) 

to be made right in the junction box. Simiar to the BP SX-20U.

Weathertight Conduit Ready Junction Box

This conduit ready J-type junction box has accessible terminals for easier module interconnections in off-grid solar PV systems. 

It features cable glands that allow for fitting of various cable sections. Gaskets are included. 

The box is securely attached to the module frame wall for added durability.

Durable Frame and Backsheet

This solar module features a rugged weatherproof anodized aluminum frame for longevity in high-wind conditions. 

The thick, durable, scratch resistant backsheet provides extra insulation for increased protection against the elements and rough handling. 

The white polyester backsheet material lasts the life of the module and increases energy production.

High Reliability

Cell interconnections and diode placement use well-established industry practices and are field-proven to provide excellent reliability.

Pre-drilled Mounting Holes

The anodized aluminum frame features clean pre-drilled mounting holes for solid grounding and attachment to the PV module mount.
