I’m a student in college and sometimes I want to sit outside and work, but there are no outlets in the field. I can use a laptop but at full screen brightness to see in the sun, it drains the laptop battery in under an hour. I don’t think I can run a 100+ watt performance laptop but I’m hoping I could run a netbook on solar power. I would like the system to be expandable in the future, but for now the panel, batteries, and anything else needed shouldnât more than $100 total. Please help.
