The GWSOLAR 200W Solar Panel is designed for homeowners and van-life enthusiasts who need high energy density in a compact form factor. By utilizing back contact cell technology, this panel delivers an impressive 22.47% efficiency, making it an ideal choice for roof spaces where every inch of square footage counts. While the all-black aesthetic provides a sleek, modern look for any installation, users should note that the panel requires a compatible MPPT charge controller to achieve optimal performance across 12V or 24V battery systems.

Yes, but you must use an MPPT charge controller to step the voltage down efficiently from the panel's 29.8V.
Yes, the panel is built for outdoor use with a corrosion-resistant frame and weather-sealed construction.
Yes, you can connect multiple panels in series or parallel depending on your charge controller's input voltage and current limits.
Beyond the sleek, uniform appearance, the back-contact cell technology used in this design removes front busbars for higher efficiency.
No, the panel includes the frame and cables, but mounting hardware (like Z-brackets) must be purchased separately based on your mounting surface.
The panel weighs approximately 10.5 kg, making it relatively easy to handle for most installations.
Check the angle toward the sun and ensure there is no partial shading or heavy dust on the panel surface.
Check all cable connections for secure contact and verify that the MPPT controller is compatible with a 29.8V nominal voltage.
Ensure there is a small air gap between the panel and the mounting surface to allow for heat dissipation.
To ensure peak performance, always pair this 29.8V panel with a high-quality MPPT charge controller that can handle the 6.72A current. Before mounting, verify that your roof structure can support the 10.5 kg weight and provide sufficient airflow underneath to prevent excessive heating. Clean the surface periodically with a soft cloth and mild soap to remove dust, pollen, or bird droppings, as heavy buildup can trigger the bypass diodes unnecessarily and reduce overall output.
