Victron 305W Solar Panel – Monocrystalline Panel

Victron Energy Solar Panel 305W Mono series 4b BlueSolar – SPM043052002

The Victron 305W Monocrystalline Solar Panel is the perfect addition to any off-grid application. They are pre-wired with MC4 connectors, making for easy installation. Their sturdy, anodized aluminium frame allows the solar panels to be easily roof-mounted with a variety of standard mounting systems. A sealed, waterproof, multi-functional junction box provides a high level of safety.

This Victron 305W solar panel is monocrystalline, which means that each solar PV cell is made of a single silicon crystal. Monocrystalline solar panels are more efficient than polycrystalline solar panels, so you will get a higher solar yield from your panels.

Victron 305W solar panel – use cases

The Victron 305W solar panels are suitable for off-grid applications such as campervans, boats and tiny houses. 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. A single 305W panel will provide a sufficient open circuit voltage.

Solar panel mounting options

Depending on your application, this solar panel 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.
