At Photonic Universe we love high quality solar products. That's why we have developed this state-of-the-art solar panel 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 50W 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 50W 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.

This high efficiency 50W flexible waterproof monocrystalline solar panel 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. The panel can also be used to provide a direct power supply for applications not sensitive to changes in input voltage / current (e.g. electric motors or pumps) and for various grid-tie applications.

The back-contact solar cells with an efficiency of up to 25% make this panel ideal for applications where space is restricted, or where there are obstructions on the roof.

Other benefits:

  • Flexible design 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 incredibly light (only 1.3kg) which is great for all vehicles
  • High resistance to salt water environment and possibility to walk on the panel make it perfect for boats and yachts.
  • Sealed waterproof design ensures the panel can be used in all weather conditions.
  • Long-lasting, highest efficiency back-contact monocrystalline solar cells will give you years and years of consistent, free power

 

The panel is fitted with 2 x 0.9m of cable specially designed for solar panels to carry high currents with negligible power loss (2.5mm cross section). The cable comes with waterproof MC4 connectors which can be used for easy connectivity to your existing system, for linking several panels together or for connecting 2.5mm extension cable.

The product is covered by a 1 year workmanship warranty provided by Photonic Universe. We will repair or replace defective items at our discretion. For more information please refer to our Terms and Conditions.

In addition, solar cells are guaranteed to produce at least 90% of nominal power in 10 years after purchase and at least 80% of nominal power in 25 years after purchase. This warranty is provided by the manufacturer of solar cells.

 

 

This solar panel is not supplied with an installation manual as it needs to be connected to further devices such as a solar charge controller or inverter which are supplied with a manual.

Charging a 12V battery: please note this panel does require a solar charge controller / regulator to charge a 12V battery. It cannot be connected directly to the battery.

Fitting: this flexible solar panel is normally fitted to a roof using a suitable sealant / adhesive (not included). It can also be screwed or bolted to the roof, by gently drilling holes into the corners and sides of the solar panel (where there are gaps between solar cells).

If you need help with installation or have any technical questions we can provide FREE support - please contact us by email or phone (see Contact Us page for more information).
