During the day, hand quilting on the screened-in porch or inside the cottage is not a problem. Lots of natural light. Nighttime is a different story. Until a few years ago, all we had were propane lights and they were not the best for hand work of any kind.
What happens if it is a cloudy day? The battery will still recharge a bit. We could probably go about 3-4 days before recharging, but we like to have it charged up and ready all the time and we take advantage of the sun whenever we can.
So, now you know how we do it here in Canada. There are far more elaborate solar systems, but this works for us for the time being and it is not very expensive to purchase and install.
Have a great day!
