Do solar chargers need direct sunlight?

Do solar lights need direct sunlight? No, solar lights do not need direct sunlight to charge. They do require light in some form to power them on, however. This may be produced through indirect sunlight – think cloudy days – or via artificial light sources like incandescent bulbs or LED lamps.

Do portable solar panels work?

Yes, they are. The same technology that allows homes to run on 100% solar energy is used, albeit in a much more compact design. Because of this, they can’t provide as much energy as full size solar panels, but they are effective. What do you need for portable solar power?

Do solar chargers work on cloudy days?

Yes, solar panels do work on cloudy days — but not as effectively as they would on a sunny day. Expect them to produce 10-25% of their normal power output, depending on how thick the cloud cover is.
