Specifications side by side

Key specs for choosing JJN panels

1. Check individual panel wattage

   Look at the size of each single panel to estimate total output. The top pick lists a 425W size per panel, which means the pack delivers high energy for heavy off-grid loads. The budget option offers a 200W size, suitable for smaller daily needs. Higher wattage per panel reduces the number of units you need to mount. This simplifies installation and wiring complexity for your specific power station setup.

2. Measure physical dimensions carefully

   Verify that the panel fits your available space on an RV roof or boat deck. The 425W model measures 67.8 inches in length and 44.6 inches in width. The 200W unit is shorter at 53.7 inches long and narrower at 30.3 inches wide. Ensure you have enough clearance for mounting brackets and airflow. Precise measurements prevent fitment issues and ensure secure attachment during travel or stationary use.

3. Assess weight for portability

   Consider how much weight your mounting surface can support. The 425W panel weighs 51.6 pounds, which is manageable for fixed rooftop installations but heavy for frequent movement. The 200W model weighs only 25 pounds, making it easier to handle and transport. Heavier panels often offer more durability but require stronger mounting hardware. Lighter panels provide flexibility for temporary setups or smaller vehicles with lower weight limits.

4. Review frame thickness

   Check the width of the panel profile if space is tight. The 200W panel has a slim 1.18-inch width, allowing it to fit into confined areas without protruding excessively. The larger 425W and 850W pack panels are slightly thicker at 1.2 inches. This minor difference matters when mounting panels close to other equipment or in low-clearance spaces. A thinner frame can also reduce wind resistance on moving vehicles.

5. Identify cell technology type

   Note the cell type to understand efficiency potential. The 850W pack and the 425W model both use N-Type cells, which generally offer better performance in low-light conditions and higher durability. The 200W model does not specify the cell type in its attributes, so you should verify this if efficiency is critical. N-Type technology often correlates with longer lifespan and lower degradation rates. This spec helps you predict long-term energy yield.
