FAQs
Need more detailed guidance beyond this page? Our full FAQ covers setup, compatibility, and troubleshooting—click below to learn more.
Is JJN 100w solar panel for a 12V or 24V system?
JJN 100w solar panel features a open-circuit voltage (20.8V) and is compatible with 12V battery systems.
if you expect long-duration partial shading (e.g., trees, debris, roof racks, or boat masts that frequently cast shadows), a 12V system generally provides greater stability and more reliable charging performance under these non-ideal lighting conditions.
Note:
This recommendation applies only when using a single panel. System behavior under series or parallel configurations is not included in this discussion, as multi-panel setups introduce different electrical characteristics.
What kind of charge controller do I need for the jjn solar panels?
We strongly recommend using an MPPT charge controller for the best performance and compatibility.
MPPT controllers are far more efficient and make full use of your panel’s voltage—even under weak or changing sunlight. Some third-party PWM controllers may not work properly, so MPPT is the safer choice.
Why is the measured power output often lower than the rated power for solar panels?
To provide our users with a superior product experience, our rated power is actually higher than 100W. We utilize Grade A+ cells, ensuring our products deliver an actual power output exceeding 100W.
Rated power is based on ideal lab conditions (1000W/m² sunlight, 25°C, no shading). In real use, factors like sunlight angle, temperature, shading, dust, and cable loss often reduce actual output.
Can this panel be used with different solar generators or battery systems?
Yes, the 100W solar panel is compatible with most popular solar generators and battery systems. It comes equipped with MC4 connectors, making it easy to integrate with a wide range of solar power setups.
Can the solar panels be connected in series or parallel?
Yes, they support series (↑voltage) or parallel (↑current) connection via solar connectors. Use same brand/model panels for best results.
Do solar panels require maintenance?
Yes, solar panels require maintenance. Dirt and stains can reduce sunlight conversion efficiency. Regularly clean the solar panels by gently wiping them with a damp cloth. Do not use corrosive liquids to clean the solar panels.
What does off-grid and on-grid mean ?
On-grid simply means solar power equipment (array or solar panel) is connected to the electrical grid, while off-grid refers to systems that are not connected to the grid and therefore store the generated power for later use.
How many solar panels do I need ?
To determine solar panel needs, calculate the power load (Watts) and capacity (Watt-hours). Size the battery bank based on minimum capacity, then adjust panel quantity or power input accordingly.
