We added a solar panel to each of our ieGeek cameras at time of purchase. We are accustomed to having to replace 4 X CR123 in each of our old Arlo cams, so the cost of the solar panels seems (should prove to be) a cost efficient upgrade for the new ieGeek camera system of ours. The mounting brackets for the solar panels are marginally better but still need betterment IMO. The 10 cord solar panel to camera would benefit from a couple of extra feet too. But,these DO keep my cameras fully charged day in and day outso its worth having them.
