Product Info :

If you have a boat or recreational vehicle that relies on batteries for running electrical lighting and on board electrical devices, you will know how frustrating it can be to arrive to find the batteries are weak or fully discharged.

Arrive to be met by fully charged batteries!
Extend battery life
Peace of mind your batteries are being maintained whilst you are away
No running costs
Lightweight, efficient, durable and affordable

Flat batteries are at best a nuisance and at worst a hazard. Solve the problem with the abundant natural power of the sun using Spectra solar panel.

Flexible and lightweight
Rugged, durable construction
Fully weatherproof
Sealed junction box and 3m of cable
Built in blocking diode
Simple to install and maintenance free.

Spectraflex amorphous solar technology

The Spectraflex is a solar panel made from a spectrum splitting amorphous silicon cell design that converts very low levels of light to useable solar energy. Unlike other types of amorphous silicon technology the Spectraflex is very stable over many years where others degrade rapidly soon after deployment. Bypass diodes are connected across each cell so the panel is also shadow tolerant.

Spectraflex flexibility

Spectraflex 32 is a highly flexible panel constructed using UV stabilised polymers, bonded and stitched to a cushioned backing material. The whole unit can be curved round in either plane and direction and rolled to a diameter of just 30cm for storage and in use placed on to curved surfaces such as a sail boom or a coachroof.

Spectraflex durable construction

Built from UV stabilised polymers, bonded and stitched to a cushioned backing material. The efficient and stable amorphous silicone cells are robustly encapsulated so the module can be walked on in soft soled shoes

Portable and lightweight

Ideal for temporary installation as no mounting holes need to be drilled Each panel has 4 corner eyelets for attaching with rope or bungee cords Can be rolled out flat or just hung facing the sun Simply stow it away when not in use

Weatherproof

The whole panel is weatherproof and carries a 2-year limited warranty

Spectraflex Built in diodes

The built in diodes connected across each solar cell make the panel shadow tolerant allowing it to be mounted beneath rigging etc with minimal effect on efficiency.

Built in diode also prevent current flowing out of the battery during hours of darkness, this means that Spectraflex can be connected direct to the battery. Please note asuitable solar charge controller may be required in some circumstances - see below.

What size solar panel do I need?

In the UK we recommend a minimum ratio of 10W (Watts) of solar panel to every 100Ah (Amp hours) capacity of battery; so a single 32W Spectraflex panel is suitable for maintenance of a 12V battery up to 320Ah capacity. Used at this ratio the solar panel will replace natural battery discharge typically experienced over the winter time and provide additional charge in the summer time.

Generates up to 9Ah per day in UK summertime, 63Ah weekly - useful for charging batteries for weekend use and invaluable for topping up whilst underway.

And, importantly, you’ll arrive to a charged battery!

Do I need a charge controller?

A solar charge controller (solar regulator) will manage battery charging and prevent battery overcharging if the solar panel is left connected to the battery for long periods unattended.

If your battery is smaller than 320Ah capacity or you will be leaving the Spectraflex 32W connected to the battery and unattended we recommend the use of solar charge controller to prevent battery damage through overcharging.

If you do require a solar charge controller the Solsum 5 and Solsum 6.6F are both suitable for use with a single 32W Spectraflex solar panel (use a Solsum 6.6F or Solsum 8.8F with 2 Spectraflex panels).

Can I use multiple Spectraflex panels together?

Spectraflex solar panels can be used together but are only suitable for 12V connection - connect in parallel (+ to +, - to -) to increase array wattage at 12V.

These panels are also well suited to use in conjunction with Rutland wind chargers : Rutland 504 , Rutland 913 and Rutland FM910-3 .
