Grecell 200W
Solar panel. Specs from the manufacturer page (checked ).
The Grecell 200W is a 200 W solar panel that uses monocrystalline silicon cells to convert sunlight into direct current (DC) electricity. It charges a power station through a charge controller, which regulates the voltage and current from the panel. Output is lower on cloudy days, and the panel generates no electricity at night unless paired with battery storage or connected to the grid.
Key features
- 200 W output
- Monocrystalline silicon solar cells
- PET panel material
- Converts sunlight into direct current (DC) electricity through the photovoltaic effect
- Connects to a power station through a charge controller that regulates voltage and current
- Output is reduced on cloudy days and at night, unless paired with battery storage
- Snow may reduce efficiency; panels are typically installed at an angle to help prevent snow buildup

FAQ
How much energy does the Grecell 200W make per day?
About 300 Wh on a short winter day (2 peak sun hours) and 825 Wh in summer (5.5 h), after 25 % losses for angle, heat and the charge controller. Rated 200 W.
How long does it take to recharge a 1,000 Wh power station?
About 1.2 sunny summer days or 3.3 winter days with this one panel. Check that the station's solar input accepts the panel's voltage.
