Spectralite 20 Solar Charger
The Spectralite 20 (19W) 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 for money.
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
- 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 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 Spectralite 20 (19Wp) panel is suitable for maintenance of a 12V battery up to 190Ah 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 20W panel has the potential to produce 6 Ampere hours (Ah) per day and therefore 42Ampere 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?
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.
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).
