Just because you’re out in the wild doesn’t mean you have to be disconnected. Even now a days you can get service almost anywhere in the United States, even in the woods or mountains. But what happens when you finally run out of juice? That’s where portable solar panels come in.
You wont be able to charge your laptop as they require around 60w and for that you’d require a solar panel that’s portable but a little bulky if you plan on going out into the wild. For higher wattage the solar panels are encased in suitcases but also come with their own batteries so that you don’t have to worry about overloading your electronics as the power would be coming from a DC source.
They range in the 10′s of dollars. Low end models around 15$ to higher end up into the hundreds. You generally get what you pay for. Solar panels can be found on ebay for cheaper and depending on the seller you might get a deal, truely it’s probably better just to buy a brand new model. They’re not that expensive, but also there not common yet either.
What will influence the cost is the type of panel and what it’s made out of. The solar panels could be amorphous, polycrystalline, monocrystalline or CIGS. The panels could be foldable, as multiple panels, in a suitcase, roll-able or as a solar backpack. Then of course if there are any batteries or accessories depend on the model being purchased.
