BSM020M 20 W Monocrystalline Solar Module

Product overview

What It Is and What It Does

The BSM020M is the monocrystalline 20 watt option, and it is a different shape from the multicrystalline version: 650 × 306 × 17 mm, long and slim, only 17 mm deep. On a narrow roof section or along the edge of a camper that thin profile is often what decides the choice.

Electrically it delivers 20 W at STC with a maximum power voltage of 17.2 V and maximum power current of 1.16 A, to a ±5 % tolerance. Maximum system voltage is 750 VDC with a 10 A series fuse rating, and it ships with a 1000 mm 18 AWG cable in an anodised 6063-T5 aluminium frame.

Who it is for

• Battery charging and maintenance on vehicles, boats and plant left standing
• Off-grid instrumentation, monitoring and signalling installations
• Camping, caravan and marine leisure power
• System integrators and kit assemblers buying modules and mounts together

Problems it solves

• Leisure and starter batteries discharge and sulphate when a vehicle is laid up
• Running a cable or a generator to a remote instrument is rarely worth the cost
• Undersized modules never bring a battery back to a full state of charge
• Modules bought without matching mounts arrive with no way to fix them down

Materials and manufacture

What It Is Made From

Monocrystalline silicon cells in an anodised aluminium frame, alloy type 6063-T5, with a 1000 mm 18 AWG cable.

Quality and certification

Everything in the BSM020M table above is taken from our own product documentation — 20 W at STC and a 650 × 306 × 17 mm (26 × 12 × 0.67 in) module. Nothing on this page is estimated or rounded up to make a better headline. If a tender needs a written certification or test statement, tell us which standard it names and we will say what we can supply.

Customisation
