Generate sustainable power easily with the Mestic Solar panel Back Contact MSBC-300. The Back Contact solar panels reduce the shadow cast on the solar cell, resulting in high efficiency. Provide all your devices with the power they need and enjoy extra freedom.
High energy yield with back contact technology
With the Mestic Solar panel back contact MSBC-300, you are less dependent on the mains for electricity at the campsite. With back contact solar panels, the electrical contacts are located on the back of the solar cell instead of the front. This increases the amount of light that the solar cell can receive because there are no metal lines on the front of the cell that block the light. This technology often provides the highest efficiency with yields that can vary from 21% to 23% or even higher. It also gives the solar panels a sleek appearance, with no visible wires or contacts on the front. Use your green electricity to power the kettle, microwave or vacuum cleaner.

Weatherproof and wear-resistant
The Mestic Solar Panel Back Contact MSBC-300 is perfect for your camper, caravan or boat. The set consists of a Back Contact solar panel, two mounting brackets, a roof duct with cable connections and a connection cable. The connection cable, with a diameter of 2.5 mm and a length of 500 cm, can be easily connected to the charge controller. In addition, the solar panel complies with ISO and technical quality requirements as well as European legislation for safety, health and the environment. This ensures you of a safe and high-quality solar panel. Furthermore, the panel performs excellently in all weather conditions and is wear-resistant, which ensures an extra long lifespan.
Do you enjoy the freedom of camping? With a Back Contact solar panel, you are less dependent on the mains for electricity at the campsite. The Back Contact solar panels are available in different sizes.
Why choose this panel?
• Premium back contact solar cell technology offers some of the highest efficiency available in the Mestic range. • Powerful 300W output designed for serious off-grid setups and high daily energy consumption. • Ideal for large caravans and motorhomes that run multiple 12V appliances or use inverters for light mains devices. • Strong, weather resistant construction suitable for permanent roof installation.
What this panel is best for
The MSBC-300 is perfect for long touring trips, off-grid stays and vehicles with significant power requirements. It provides robust charging to support cool boxes, fans, pumps, lighting, chargers and other essential 12V equipment, helping to keep your leisure battery topped up even with heavy daily use.
Good to know
• Always pair the panel with a suitable 12V solar charge controller to protect your leisure battery. • Compatible with AGM, Gel and Lithium batteries when used with the correct controller settings. • Install the panel in a clear, unshaded roof area and clean the surface occasionally to maintain maximum efficiency.
Below is a quick guide to what each of these figures means in day-to-day use,
so you can judge whether this panel will comfortably support the way you camp.
Max power (W)
This is the peak wattage the panel can produce in strong sunlight.
A higher watt rating means more total energy over the course of the day,
so it’s easier to keep leisure batteries topped up when you’re running cool boxes,
pumps, lighting and multiple USB devices.
If you spend several nights off-grid or rely heavily on 12 V appliances,
prioritise panels with higher wattage for more reliable daily charging.
Max current (A)
Max current is the highest charging current the panel can deliver through a suitable
solar charge controller. The higher the amps, the faster your leisure battery can
recover after use, especially during shorter daylight windows.
This is particularly important for campers who arrive late on site, use a lot of
power in the evening or run Lithium batteries that can safely accept faster charging.
Max voltage (V)
Max voltage shows the panel’s operating voltage under load. Higher voltage helps
reduce losses over longer cable runs – for example on larger motorhomes or roof-rack
installations where the panel is some distance from the charge controller.
It also gives you a bit more headroom in cooler or cloudier conditions when panel
voltage naturally dips, helping the controller stay within its ideal working range.
How this affects your set-up
Together, these three values give a good picture of real-world performance:
max power tells you how much energy the panel can produce in a day, max current
shows how quickly it can recharge your battery, and max voltage indicates how
efficiently it will deliver that power through your wiring.
If you mostly stay on hook-up or only trickle-charge a battery between trips,
a lower output panel may be perfectly adequate. If you regularly camp off-grid,
run several 12 V appliances or depend on solar as your main charging source,
choosing higher outputs in all three areas will provide noticeably stronger, more
dependable performance.
