Specifications side by side

How to choose the right ECO-WORTHY solar panel

1. Match wattage to load

   Start by calculating your daily energy consumption in watt-hours. The ECO-WORTHY 25W Monocrystalline Solar Panel is designed for low-demand tasks like maintaining 12V batteries on boats or gate openers. It provides just enough power to offset self-discharge. If you need to run appliances, look at higher wattage options like the 200W kit. Ensure your panel output matches your inverter and battery capacity to avoid underperformance or wasted space on your roof.

2. Check voltage compatibility

   Verify that the panel voltage aligns with your battery system. The 25W model outputs 18V, which is standard for charging 12V batteries. The 200W kit supports both 12V and 24V systems, offering flexibility for different setups. The 800W kit also handles 12V and 24V configurations. Always check the open-circuit voltage and maximum power voltage in the specs to ensure your charge controller can handle the input without exceeding its limits.

3. Assess physical dimensions

   Measure your available mounting space before buying. The 25W panel is compact, measuring 16.5 by 12.6 inches, making it suitable for small RVs or curved surfaces. The 400W N-Type 100W modules are larger at 35.2 by 23 inches. The 800W kit includes panels that are 58.9 inches long. Ensure you have enough flat, unshaded area. Larger panels generate more power but require more structural support and careful placement to avoid shading from vents or antennas.

4. Consider weight limits

   Weight matters if you are mounting panels on a vehicle roof. The 25W panel weighs only 4.54 pounds, which is easy to handle and install. The 400W N-Type 100W modules weigh 23.8 pounds each, so a four-pack adds significant load. The 200W kit weighs 31.6 pounds total. Check your roof’s weight rating. Heavier panels may require reinforced mounting brackets. Lighter panels are easier to move but may offer less total power for the same footprint.

5. Evaluate kit completeness

   Decide if you need a standalone panel or a complete system. The 200W and 800W options are sold as kits that include charge controllers. This simplifies setup for beginners who do not want to source separate components. The 400W N-Type pack and 25W panel are sold as panels only. You will need to purchase a compatible charge controller and cables separately. Kits save time but may limit your choice of controller brand or features.
