This high efficiency flexible waterproof 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, and complete household solar power systems.

Flexible solar kit includes:

  • 100W flexible solar panel made of special back-contact solar cells with a strong ETFE coating
  • 10A automatic solar charge controller with advanced connectivity options
  • A pair of 5m 4mm single core extension cables with MC4 connectors
  • 5m 4mm thick double core battery cable

 

100W flexible solar panel:

This state-of-the-art solar panel is made of back-contact solar cells - the newest generation of solar cells which have a significantly higher efficiency compared to standard solar cells (which means they extract more sunlight energy from the same area). The back-contact solar cells used in this solar panel have an unparalleled efficiency of up to 25%, which makes this the smallest and most efficient 100W flexible solar panel commercially available in the world. The solar cells used in this panel have been manufactured by SunPower - one of the largest US solar manufacturers, using the newest production equipment and cutting edge technology. If you would like to learn more about back-contact solar cells and their benefits, check out our article Introduction to back-contact solar cells which explains the differences between back-contact solar cells and regular front-and-back contact solar cells.

This 100W flexible solar panel is made of strong ETFE material which has a longer service life compared to standard semi-flexible solar panels. As a result, these particular flexible solar panels are extremely robust 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.

The 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 panel is also incredible light (only 2.33kg) 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 0.9m of cable with MC4 connectors at 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. Other features of this controller include LED indicators, temperature sensor, and a load "on/off" button. One of the greatest benefits of this powerful 10A controller is the small size - only 14x7cm.

This controller can work with sealed, gel and flooded batteries (the default is sealed) or a user-defined battery type (please note battery type can only be changed from default using one of the communication methods listed below). The controller can accept up to 160W (12V battery) / 320W (24V battery) of solar power input, which makes it a perfect choice for small or medium solar PV systems with a battery and load such as in a campervan or boat.

The solar charge controller also features advanced communication technology, which offers the user the opportunity to monitor and program parameters for the solar charge controller through various methods:

1) The controller can be connected to a remote meter MT50 with an LCD screen, which displays system performance information, and allows the user to manually adjust parameters and load settings

2) The controller can be connected to a Wi-Fi module to create a Wi-Fi network, to which your mobile phone or tablet can connect, in order to monitor or adjust charging parameters and controller settings through a free mobile app - Solar Station Monitor (Android-based phones and tablets only).

3) An RJ45 to USB cable can be used to connect the controller directly to your PC / laptop, where parameters and settings can be monitored and adjusted via a free computer program - Solar Station (Windows-based PCs and laptops only).

Using one of these communication methods, the user will gain access to various charging parameters such as voltage, current (separately for solar panel / load), battery state of charge, accumulated charge and discharge energy, min/max voltage and other information. If required the user will also be able to amend the battery type and capacity, set charging volts for different charging stages, specify the duration of each charging stage, create a user-defined battery type with charging parameters specific to their battery (if the pre-existing options are unsuitable), personalise the 'load' settings (e.g. set timers for lighting, fans, pumps) and more.

In addition to the built-in temperature sensor, the controller has a pair of terminals for connecting a remote temperature sensor, which can be attatched 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 (4mm cross section) and 5m of 4mm dual core battery cable for use between the solar charge controller and your battery, making the total cable length between the solar panel and the battery 0.9m + 5m + 5m = 11m.
