Extra flexibility seems to be the USP of Renogy. Offering a 248-degree range of flex, it seems to be a perfect fit for surfaces with an excessive curve. This would work well on soft surfaces, making it one of the best marine flexible solar panels.

It is quite similar to the other Renogy flexible solar panels. This version gives you the capacity to obtain around 100 watts from one panel under full sun. Depending on your requirement, you could install more than one in parallel connection to increase ampere capacity or in series connection to increase the voltage capacity.

If you are in hurricane-prone areas or places prone to snowstorms, this product proves to works positively to sustain these conditions and pressures.

Ease in the installation is a boon. You could stock these onto your roofs using silicon adhesives, use the copper mounting holes to fasten it to the required surface or use Velcro. Some also prefer to make a lightweight frame using PVC. You could adjust these frames according to the movement of the sun.

This medium-capacity solar panel with 100W output is sufficient to power electric pumps, fan, lights, and a gas heater. This is perfectly achieved without witnessing any drop in the voltage.

Why are we impressed?

• Lightweight, extra flexibility
• Resistance to harsh weathers

What negatives must you be aware of?

• Chances of ending up with a poor quality panel

Your family’s energy needs are the basis of this solar panel’s design. It has incorporated the shingle technology assisting the conduction of solar power among the solar cell units through a conductive adhesive.

The solar power output in low lit areas is quite efficient as the shingle technology prevents wastage of solar power. Unlike the conventional solar panels and also a number of its counterparts, this design is solderless. The technology used to connect the battery wafers in this product helps in trapping the solar energy at an excess of a 15%per unit area. This new mechanism has proved to increase the performance as well as the durability of the flexible solar panel designed for RVs, boats, and roofs with uneven surfaces.

Panels are lightweight making the installation and transportation process a breeze. Its net weight is less than 4lbs and the flexibility ranges to about 30 degrees. These panels could be fixed with adhesive tape without requiring any drilling of holes. When it comes to maintenance, you don’t have to break your head since this product comes with a self-cleaning feature. The panels tend to get clean with rains. It has a nonstick surface enabling easy cleaning. The junction box is waterproof so you don’t have to worry about shorting. These panels could withstand hailstorms and heavy rainfall.

This flexible panel is compatible to charge a 12V battery which could be either a lead-acid or a lithium battery. It is also beneficial to connect devices like water pumps as well.

What stands out?

• Solderless technology
• Waterproof junction box
• Laminate design

What cons did we manage to find?

• Chance of having a misty panel
• Flexibility is lesser than its counterparts

A solution to deal with the loss of battery overnight is this flexible solar panel. The junction box has an inbuilt blocking diode. The advantage of having this blocking diode is to sustain the charge in the battery through the nights. You seemingly would not have to face discharge and drainage of the battery hence allowing minimal wastage of charge. This increases the efficiency of battery performance.

These flexible solar panels are designed with 36 monocrystalline cells that could be taped on your RV without much effort. It offers a bendable range of 30 degrees that suits uneven and curved surfaces. With the thickness of about 0.1 inch, this flexible panel weighs about 3.5 lbs. These are laminated adding to the lightweight feature.

Both the panel and the junction box are waterproof, hence allowing them to withstand heavy rainfall and harsh weather.

Installation of these panels could be done using the available mounting holes, stick them to the roofs with an adhesive, or even use Velcro to fasten the edges onto the surface.

Considering these are flexible and thin the capacity of power output is not bad at all. They could push about 22V output under full sun charging a 12.6V lithium battery. The solar power tapped could be used to power a 300W inverter, a fan, and a radio. You get an amplified result of you incorporate a charge controller to minimize loss of charge from the battery. This flexible solar panel provides great assistance in charging batteries to provide power for led lights during nights, useful for charging laptops, phones and also enjoy some television. All this depends on how you plan your battery back-up and how many panels you incorporate.
