30W monocrystalline solar panel for 12V systems, made with 36 monocrystalline cells and designed for small off-grid solar installations. Its compact size of 465 x 385 x 25 mm and 2.2 kg weight make it suitable for battery maintenance, caravans, campervans, boats, telecommunications, auxiliary lighting and low-power electrical loads.
The 30W 12V monocrystalline solar panel is a compact photovoltaic solution for small off-grid solar installations, battery maintenance and low-power electrical loads. It is made with 36 monocrystalline cells and provides 30W maximum power, with a maximum power voltage of 17.4V and a maximum power current of 1.73A.
With compact dimensions of 465 x 385 x 25 mm and a weight of 2.2 kg, it is easy to install in limited spaces such as caravans, campervans, boats, sheds, telecommunications systems, auxiliary lighting and small 12V solar applications.
This panel is suitable when a simple, compact and reliable solar energy source is needed to support a 12V battery or power small loads. Its rigid format makes installation easier on structures, brackets, flat roofs or prepared solar mounting surfaces.
Monocrystalline technology uses cells made from monocrystalline silicon. This type of cell offers good efficiency in relation to panel size, which is especially useful when available installation space is limited.
To charge a battery safely, the panel must be used with a compatible solar charge controller. The controller manages voltage and current to help prevent incorrect charging, overcharging or battery damage.
This panel is designed for 12V solar systems and must be used with a compatible solar charge controller. Compatibility depends on the controller input capacity, the panel voltage and current, the total installed power and the battery type.
No official compatibility list with specific controller, inverter or battery brands is confirmed. Before installation, check that the controller supports at least 30W of photovoltaic power and an input current above 1.73A.
Install the panel where it receives as much sunlight as possible and avoid partial shading from branches, antennas, roof windows, masts or other elements. Even a small shadow can significantly reduce production.
The panel must be fixed to a stable and resistant surface. Use suitable brackets, compatible screws or mounting systems designed for the installation surface.
To charge a 12V battery with this panel, a solar charge controller is required. The controller must be configured according to the battery type, such as AGM, GEL, flooded lead-acid or lithium, following the battery manufacturer’s recommendations.
For maintenance applications, the panel can help compensate for small loads or battery self-discharge. If there are permanent loads, a daily energy balance should be calculated to confirm whether 30W is sufficient.
If the panel is not installed immediately, store it in a dry, clean place protected from impacts. Keep it stable, avoid placing weight on top and protect the glass and frame from scratches or damage.
Temperature affects the performance of any solar panel. On very hot days, operating voltage may decrease, while in cold conditions voltage may increase. The controller must therefore have sufficient margin for the electrical values of the panel.
Real production will also depend on orientation, tilt, season, solar radiation, panel cleanliness and absence of shading.
