Portable solar cells

Solar cells for charging batteries are now available in many attractive and practical forms. The size of the panels used changes depending on the power requirements. It is advisable to plan a "bad weather reserve" as it can happen that the sky is overcast. In the case of diffuse residual light, some energy is still generated, but it may not be enough to charge the battery. Therefore, function should be preferred to appearance.
