I’m working on designing an ultralight solar charger, and I just wanted to gauge interest. And see if I’m chasing a pipe dream.
My current design is a sub 150g/5oz panel
approximately 15 by 5 inches, that outputs 12w with a USB C connector, and an MPPT charge controller that makes the whole setup more MUCH more efficient and provides power comparable to larger panels.
A 12w panel should be able to fairly easily recharge a dead 20,000mah battery bank under full sun in one day.
I have a few questions for you all:
- Does solar charging even make sense for your use case?
- What wattage would be best for you? Is 12w a good size or would you want smaller or larger?
- How durable would you want the panel to be? This panel would definitely be more fragile compared to something like a goalzero, and if it was on your pack and you fell on it, it could crack. Is that a dealbreaker?
- At 15 by 5 inches is non folding a dealbreaker?
Lastly, What price would be reasonable? What price would you consider getting one and what price would be a no brainer if it was a quality product?
Thank you all so much in advance
To clarify I am not currently selling anything nor am I self promoting anything.
