This high-efficiency semi-flexible 100W solar panel kit is perfect for permanent outdoor use to provide free electricity for charging 12V batteries to power various applications, such as in a motorhome, caravan, camper, boat, or for solar lighting systems, off-grid and back up solar power systems.

Solar kit includes:

100W black ultra-narrow semi-flexible fibreglass solar panel with a durable ETFE coating
Advanced 10A solar charge controller with LCD display and powerful 2.4A dual USB output
A pair of 5m 4mm² single core solar extension cables with MC4 connectors
5m of 4mm² dual core battery cable fitted with a 15A fuse, fuse holder and 8mm ring terminals

100W Black ultra-narrow semi-flexible fibreglass solar panel:

This highly durable black ultra-narrow semi-flexible solar panel reinforced with fibreglass plastic has a surafce made of strong ETFE material which has a longer service life compared to standard semi-flexible solar panels. As a result, these particular semi-flexible solar panels are extremely hard-wearing and less prone to cracking, delamination and corrosion. The lightly textured coating of this panel creates an anti-reflective surface which allows the panel to absorb a far greater amount of light, thereby increasing efficiency. ETFE material has long been used in applications where durability and high-temperature resistance is required, such as in the Eden Project, Cornwall. You can read more about ETFE and its benefits here.

This panel also features new generation 5-busbar solar cells, which are more efficient than the 2, 3 or 4 busbar solar cells used in most other solar panels, and are able to extract more power from the same surface area. This results in a smaller overall solar panel, which is ideal for applications where space is limited.

This solar panel has a unique black backing, making it ideal for discreet and aesthetically pleasing installation on dark coloured roofs, vehicles or mounting surfaces. Please note that this solar panel is not 'ultra jet-black' - the exact hue may vary marginally from panel to panel, depending on the batch of solar cells.

The semi-flexible design of this panel makes it ideal for curved roofs and surfaces where bonding is preferable (though the panel can also be fixed by bolts or screws). The unique ultra-narrow shape is ideal for applications where space is restricted, or where there are obstructions on the roof (only 350mm wide).The panel is also incredibly light (only 1.72kg) which makes it an ideal option for all vehicle applications. This panel is also highly resistant to salt water environments and it is also possible to walk on the panel, making it the perfect choice for boats and yachts.

The panel is fitted with 2 x 1m of cable (4mm² cross section) with MC4 connectors on the end which simply plug into the 5m extension solar cable supplied with the kit, to join the solar panel and the charge controller.

10A Solar charge controller:

The kit includes a 10A 12V/24V Photonic Universe solar charge controller designed to protect batteries whilst charging them, with automatic cut off to prevent over-charging and deep discharge. The controller uses PWM (Pulse Width Modulation) technology which increases charge acceptance and prolongs the life of your battery. Often PWM technology can recover some lost battery capacity.

This controller stops reverse current at night (from the battery back to the solar panel) so your battery won't lose any charge. It has many other protection functions such as over charge / discharge, over load, short circuit, overheating etc.

The LCD display shows information regarding real time solar panel and battery performance, including: voltage, current, battery state of charge, and battery temperature. An energy statistics counter also displays the accumulated daily and monthly charge values (useful for comparing solar panel performance between different periods).

This solar charge controller also offers the rare and highly sought-after feature of a dual USB charging output. These 5V USB ports have a total combined output of 2.4A, offering fast and powerful charging of USB compatible devices such as mobile phones, tablets, mp3 players etc.

An optional 12V load (e.g. 12V lighting / fans) may also be connected directly to the solar charge controller, with various settings for night time lighting applications. In addition, this controller also offers various charging programs for different battery types, which can be easily selected by the user. In addition to the built-in temperature sensor, the controller has a pair of terminals for connecting a remote temperature sensor, which can be attached directly to the battery to measure the battery temperature more precisely and optimise the charging process.

Additional items:

The kit also includes a pair of 5m positive and negative solar extension leads (4mm² cross section) and 5m of 4mm² dual core battery cable fitted with a fuse, fuse holder and 8mm ring terminals for use between the solar charge controller and your battery, making the total cable length between the solar panel and the battery 1m + 5m + 5m = 11m.
