Well I’ve seen powerbanks that can dispense more than the 60w my laptop needs for around my local version of 100$, so if you can charge one of those with your solar array I think you could get far. I only have a smaller panel on my balcony and just bought a smaller powerbank (cause I hadn’t seen this one yet https://www.ankernordics.com/products/a1695-anker-power-bank-25000mah-165w?ref=4-phone-charges ) but if I can get my routines working I think I at least could get my phone on fully solar. And with 250w solar and a 165w powerbank I’d say you’re golden!
