Heliene is a North American solar module manufacturer. eMarine lists the Heliene 450W bifacial solar panel, a full-size module that collects light on both the front and the back of the panel. Bifacial panels produce extra energy when mounted with open space behind them, such as on a raised ground mount, a carport, an arch over a light-colored deck or a pergola.
How to use a bifacial panel
Bifacial gain depends on how much reflected light reaches the back of the panel, so mount it with clearance underneath and over a reflective surface where possible. Check the dimensions and weight against your structure, and choose an MPPT charge controller or hybrid inverter whose PV input voltage covers the panel open-circuit voltage in cold weather, especially with panels in series.
Is a 450W panel practical on a boat?
Only on larger boats with room for a full-size panel and a strong arch or hardtop. For smaller boats, see marine solar panels.
Which controller should I use?
An MPPT controller rated for the panel voltage. See solar charge controllers.
How is it shipped?
Full-size solar panels ship by pallet freight to prevent damage in transit.
