Environmentally friendly energy….
Modern solar power systems have a variety of uses. Here we offer off-grid
applications to provide electrical power at sites where the grid is inaccessible or too costly. There
may be good environmental reasons for choosing a renewable energy option even where the grid is
available. The systems are sustainable and often more cost effective owing to the avoidance of
major groundworks.
BP Solar have been a world leading
research, developer and producer of
photovoltaic modules since 1972. We have access to experts who can understand your system needs and
tailor a
battery charging solution to suit your
application whether that’s a solar “standalone”
or “hybrid” wind/solar kit
incorporating a Rutland
Windcharger. We will recommend to you a
balance of solar and/or wind power to
deliver you power, day or night, summer or
winter wherever you are in the world.

Okay, its not a motorhome or boat, but you get the idea:o)
BP Solar 3 Series
The 3 series is an advanced photovoltaic module that incorporates polycrystalline cells using SiN
coating to give superior efficiency.
All the solar panels have “ARC” glass, an anti-reflective coating with self-cleaning properties so that
under normal conditions panels do not require cleaning. The modules are robustly constructed using
BP’s clear anodised Universal frame and are offered with a warranty that will give you confidence in
your system for many years ahead.
Solar panels can be connected in parallel to increase power and are modular allowing the user the
flexibility to build up a system over a period of time in line with budgets and power requirements.
The 3 series modules have a 12V nominal output and are primarily designed for battery charging
applications such as:
off-grid homes
telecommunications
telemetry sites
navigation equipment
motorhomes & caravans
sailboats
………..and other sites where low power is needed.
A range of solar regulators and mounting kits are available, we will
recommend products appropriate to your system.
Product Features & Specifications – 3 Series
90% Power output warranty over 12 years
80% Power output warranty over 25 years
10 Year warranty – free from defects in materials
and workmanship
Universal frame is manufactured from clear anodised
aluminium alloy type 6063T6. Silver in colour.
Temperature cycling range of –40°C to +85°C for
200 cycles
Damp heat tested to withstand 85°C and 85% relative
humidity for 1000 hours
Front and rear static load tested eg wind, to 2400 Pa
Front load tested eg snow, to 5400 Pa
Hailstone impact tested to 25mm hail at 23m/s from
1m distance
The tempered glass is highly transmissive and self
cleaning from rainfall
Rugged and weatherproof construction - the cells are laminated between sheets of ethylene vinyl acetate
(EVA) and 3mm tempered glass with a blue Tedlar™ backsheet
36 cell panels are configured in a 4 x 9 matrix; each 2 rows of 9 are connected in series with a Schottky
by-pass diode to produce 2 x 6V strings further connected in series to produce a standard 12V nominal
output panel.
72 cell panels are configured in a 4 x 18 matrix, 2 parallel strings of 36 produce a standard 12V nominal
output.
Easy to connect - an IP54 weather rated junction box at the rear of each panel provides a 6 terminal
screw connection block* accepting 2.5-10mm² (8-14AWG) cable. The junction box knockouts accept
PG13.5, M20, 13mm conduit or cable fittings 6-12mm diameter.
*Except the BP3125S module which has 2 x 4mm² flying leads with Multicontact connectors (900/800mm)
All BP Solar modules are labelled with individual performance figures
Each solar module is supplied with a grounding screw, instruction sheet and warranty document.
