Traditional solar panels are rigid and often enclosed in tempered glass. The Renogy 50W Flexible Solar Panel is anything but traditional. Perfect for marine use or placement on top of a van or vehicle, the Renogy 50W Lightweight Solar Panel is thin and capable of flexing up to 248 degrees. At 2.87 pounds, this flexible solar panel weighs only a quarter of its traditional 50W counterpart. Highly flexible, this lightweight panel can easily be installed on curved surfaces. This panel can also be used for other various applications, including providing power on a boat or teardrop trailer.

Mounting Recommendation: Modules must be mounted using silicone structural adhesive on the backside of the panel, grommets are only to be used for non-mobile applications. For detailed installation methods, please consult a local contractor for guidance.

Key Features

Extremely Flexible
  • This panel is capable of meeting a wide range of applications where standard panels can be inconvenient to mount, such as on the curved roof of an airstream
Ultra Lightweight
  • Thanks to advanced polymer materials, this product weighs 70% less than conventional solar panels, making transportation and installation a breeze
Super Thin Lamination
  • Hardly noticeable, the Renogy 50W Lightweight Panel laid flat is only a tenth of an inch tall making it ideal for a stealthy solar setup.
Highly Durable
  • Rigorously tested, the 50W panel was designed to withstand extreme wind of up to 2400 Pa and snow loads of up to 5400 Pa

1.What do I need to complete my off-grid solar power system ?

A solar panel has to be connected a charge controller to regulate current, and a battery to store the electrical power. You will need adapter kit cables to wire the solar panel(s) and charge controller, and tray cables connecting the charge controller to a deep-cycle battery.

2. What does off-grid and on-grid mean ?

On-grid simply means solar power equipment (array or solar panel) is connected to the electrical grid, while off-grid refers to systems that are not connected to the grid and therefore store the generated power for later use. Off-grid systems are not affected by grid blackouts.

3. Why is my solar panel under producing ?

Solar panel performance may be hindered for a number of reasons. Most commonly environmental conditions such as indirect sunlight, temperature rise, cloudy sky, and dirt and stain build up on the top glass will cause a reduced power output.

4. How should I connect solar panels in my electrical circuit (series vs parallel)?

Solar panels can be connected in series or in parallel to meet your electrical circuit size and power demand. Connecting solar panels in series will have the effect of adding up their operating voltage output, while system current output will be the same as that for one panel. While, connecting solar panels in parallel will have a different effect; individual panels operating current output will add up to be the system output current, while system output voltage will be the same as the output voltage of one solar panel. To meet the optimum power output and system rating for your power system, you can use both parallel and series connections.

5. How many solar panels do I need ?

The best way to gauge how many solar panels you need, is to understand and define the power load needed from this system. Power is measured in Watts, and capacity is commonly measured in Watt-hours (multiplying power output in watts by the required number of hours of operation multiplied by a safety factor of 1.5-2). Therefore, it is wise to size your battery bank first based on the minimum required capacity, and accordingly decide how many panels or how much power input is needed.

6. Can I walk on flexible solar panels?

We suggest not. Walking on solar panels will exert excessive pressure on a small area, it may cause cracks and damage to the panel.

7. How to clean solar panels?

You can clean the panels with a non-abrasive sponge and water. We suggest regular maintenance to wipe the dust, sand, and other dirt away. Built-up dirt and stain will reduce the power output of the panel.

    Does the job

    Posted by Chickadee on Aug 1st 2021

    This panel is installed on the pilot house roof and easily powers our electronics and house battery.

    Good panel

    Posted by John on Oct 23rd 2020

    The panel is better made than the one it replaced. Initially the wrong product was shipped, but Renigy was responsive and shipped the correct product.

    Seemingly Durable and Lightweight

    Posted by Paul Yuenger on Oct 4th 2020

    I would prefer it if the + and - wires didn’t extend on opposites sides of the panel, but came out nearly together for single panel or parallel use. Only time will tell if this flexible panel is durable. Two of these replace a Renogy folding panel which quickly failed.

    Does what I anticipated when

    Posted by Robert Winters on Apr 9th 2020

    Does what I anticipated when I ordered. I thought I was ordering from Renology, I was really tired when I placed my order. When I reviewed everything a few days later, I was somewhat disturbed that I had made a mistake and ordered from a different company with a similar name.

    I’ve mounted this solar pane

    Posted by R. Mark Pasciuti on Oct 4th 2019

    I’ve mounted this solar panel on the main hatch of my sailboat and it conforms perfectly to the curve of the hatch top. This 50w panel keeps my group 27 marine deep cycle battery fully charged and has exceeded all my expectations. The panel is ruggedly constructed and the brass grommets are very convenient. Power output is perfect for my needs with incandescent cabin and navigation lights.

    Nice panel. Only getting 36-

    Posted by clinton marshall on Aug 6th 2019

    Nice panel. Only getting 36-40 watts out of it in full sunshine, so not sure it's as good as it's rated. Hoping the connectors on the panel itself hold up better than in prior versions, where they have been its Achilles heal.

    Works great and should be more than enough panel for my overland Jeep build.
