Why is the actual power output lower than 200w or 400w?
The 200w/400w rating is based on standard test conditions (stc): 1000w/m² irradiance, 25°c, and 1.5 air mass. real-world factors such as panel angle, temperature, shading, wiring loss, and device efficiency reduce power output. for best results, position the blanket at a 90° angle toward direct sunlight, in a bright, shadow-free environment.
What kinds of devices can be charged with this panel?
The 200w/400w solar blanket can charge batteries (with a solar charge controller) and portable power stations. always verify that the panel’s open-circuit voltage does not exceed the maximum dc input voltage of the connected device.
Can i use non-renogy branded power stations?
Yes. as long as the power station is compatible with the solar panel’s voltage and is used with a proper solar adapter cable. always check the specifications of your portable power station before connecting.
Why is my portable solar panel underproducing?
Solar blankets are affected by sunlight intensity, temperature, weather, and surface cleanliness. indirect sunlight, high temperatures, cloudy days, dust, or dirt on the panel surface can all reduce output performance.
How should i connect multiple solar panels for my system? should i use a series or parallel configuration?
The 400w solar blanket can be wired in series or in parallel. series wiring increases voltage while keeping current the same. parallel wiring increases current while keeping voltage the same. choose the configuration based on your system voltage and controller ratings, and ensure you never exceed your solar charge controller or power station's maximum pv input voltage.
Which solar blanket has a usb port?
Only the 200w solar blanket includes a built-in usb output port for charging small electronics like phones and tablets. the 400w model does not include a usb port.
