300W Solar Panel – Monocrystalline Panel

This high efficiency Photonic Universe 300W monocrystalline solar panel is perfect for permanent outdoor use to provide free electricity in any grid-tie, hybrid or off-grid application (such as charging batteries in vehicles or boats, or powering an off-grid house or cabin, or working with a grid-tie / hybrid inverter to feed energy into the electrical grid). Due to the size of the area that this solar panel covers it is great for large systems where the time and cost associated with fitting a high wattage array needs to be minimised.

In order to achieve high output this solar panel uses innovative 5 busbar solar cells, which are more efficient than the 2, 3 or 4 busbar solar cells used in other solar panels, and are able to extract more power from the same surface area. This results in a smaller overall solar panel for the same power rating.

On the back of the solar panel there is an IP68 (fully waterproof) junction box with 1m of special solar cable which can operate at high roof temperatures with minimum power losses. A pair of male / female MC4 compatible connectors are crimped on the end of the cable for easy connection to other solar panels, extension leads or your existing system.

The panel is encased in a robust 35mm thick frame made of anodized aluminium alloy for structural rigidity and many years of stable output. The waterproof design and non-corrosive materials ensure that the panel can be used in all weather conditions and locations, including marine applications where contact with sea water is likely.

Each individual solar panel is thoroughly tested to the highest quality standards, and labelled with a unique serial number for further quality control and increased warranty protection.

Solar panel mounting options

Depending on your application, the Victron 40W solar panels can be mounted in a number of ways. If you have a roof rack you can mount directly to this. Otherwise, you can use mounting brackets to attach your solar panels to the roof of your campervan.

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, 1% of the total cost will be given 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.
