Sunman 175W Flexible Solar Panel – eArc Monocrystalline Panel

Sunman 175 Watt Flexible Monocrystalline Solar Panel – SMF175S-4x09DW

The Sunman 175W flexible solar panel is capable of flexing up to 248 degrees, so you can easily install it on curved surfaces, making it perfect for boats and campervans. The panel is lightweight and thin, weighing only a quarter of its traditional rigid counterpart.

This Sunman 175W flexible solar panel is monocrystalline, which means that a single silicon crystal comprises each solar PV cell. Monocrystalline solar panels are more efficient than polycrystalline solar panels, so you will get a higher solar yield from your panels.

Sunman 175W flexible solar panel – use cases

The Sunman 175W solar panels are suitable for off-grid applications such as campervans and boats. The very thin form factor also makes them perfect for stealth campervan setups.

When used in a campervan setting, we would recommend a minimum solar array of 200W. This will ensure that you are able to generate enough solar power even in winter or cloudier days. An open circuit voltage of 15V or higher is required to charge your system, so we would recommend wiring your solar panels in series to achieve a higher total system voltage.

Solar panel mounting options

Flexible solar panels must be mounted using silicone structural adhesive on the backside of the panel. Grommets are only appropriate for non-mobile applications.

Solar charge controllers

Once you’ve decided on the size of your solar array, make sure you find the correct solar charge controller! You can calculate your maximum open circuit voltage by adding together the voltages of each of your panels (if wired in series). Your maximum open circuit current will remain the same (when wired in series). Victron charge controllers are sized based on these 2 numbers – e.g. the 100/30 charge controller is suitable for an open circuit voltage up to 100V and an open circuit current up to 30A.

Products that give back

We are members of 1% for the Planet. This means that for every product purchased from Nohma, we will give 1% of the total cost to The Honnold Foundation, to provide solar power to underprivileged communities. If you want your electrical system to have more of a positive impact, purchasing your components from us at Nohma will mean you can give back as well as powering your off-grid system.
