The Spectralite 10W semi-flexible solar panel is ideal for maintaining and replacing natural discharge in deep cycle 12V batteries for leisure applications. Popular with marine users, Spectra solar panels offer durability, reliability and excellent value.

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.
Spectralite Solar Features 
  • Semi-flexible
  • Rugged, durable construction
  • Slim and lightweight
  • Fully weatherproof
  • Sealed junction box and 3m of cable
  • Built in blocking diode
  • Simple to install and maintenance free.

Semi-flexible Spectra Solar Power

Spectralite solar panels can be gently flexed to follow the curve of a boat / RV roof or deck. Maximum curve is 3cm over 1m proportionately.

Fix using the 4 screw holes in the panel or using suitable adhesive.

Spectra Construction

Spectra Solar has been designed with the yachtsman in mind and all models share the following important features :

  • robust design and build - they can even be walked on in soft soled shoes
  • conveniently lightweight and slimline so easily installed
  • sealed junction box with blocking diode and 3m of output cable
  • corner fixing holes sealed with an eyelet for a quality finish

All solar panels in the Spectralite range are made from efficient and stable crystalline solar cells. The cells are sealed between the lightweight a durable fibreglass back and Tedlar front and are fully weather proof. Tedlar is used as it is light weight, scratch proof and has excellent light transmission properties.

All Spectra solar panels come with a 2 year limited warranty.

Spectralite Built in diode

The built in diode prevents current flowing out of the battery during hours of darkness, this means that Spectra panels 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 capacity of battery (so a single 10W Spectralite panel is suitable for maintenance of a 12V battery up to 100Ah capacity). Used at this ratio the solar panel will replace natural battery discharge typically experienced over the winter time.

In the summer the solar panel’s performance increases so a 10W panel has the potential to produce 3 Ampere hours (Ah) per day and therefore 21Ampere hours (Ah) weekly - that’s often enough for a weekend’s cruising electrical needs for lighting etc.

Most importantly you’ll arrive to a battery that is not flat!

Do I need a charge controller?

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.

As a general rule of thumb, if the ratio of 10W of solar panel to every 100Ah of battery is not exceeded a charge controller is not required.

If you do require a solar charge controller the Solsum 5  and Solsum 6.6F  are both suitable for use with the 10W Spectralite panel.

Can I use multiple Spectra panels together?

You can connect Spectra solar panels together - connect in parallel (+ to +, - to -) to increase array wattage at 12V. Connect in series (+ to -, - to +)to increase array voltage (usually to 24V).

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

Customer Review Spectalite 10W:


Dear Bill, I bought a small solar panel (Spectra 10) from you a few months ago for my boat and, having used it now for several months, thought I would drop you a quick line to say how pleased I am with it. Last year, without it, I suffered from dodgy batteries for the whole season but this year the situation has been transformed for so little cost. Thank you for your service and for the help you gave me during the installation earlier this year.

Best wishes
