>>2316832Solar main problem is it needs to be massively over built just to power a light.
Even then you will still need a normal battery charger for days without direct sunlight.
Solar really only powers a light for a few hours a day.
You are almost better off with just a battery charger and batteries.
But if you still want to go solar, then 100 watt panel will deliver 10-90 watts of power. You also need to keep any battery over 50% charge.
So you get to use only 1/4 of the battery and 1/4 of the solar panels power.
You also need a way of turning off solar panels on bright days and turning on solar panels on dimmer days or your charge controler will overheat.
So its a lot of up front costs just to run a light.
Then the batteries will need to be replaced every 5-8 years or you wount have the power you think you will when you need it.
Solar really only works in the summer and only for 4 hours a day.
Bigger batteries need more charge just to maintain the batteries level of charge.
Batteries lose charge during the night even if you arn't using them, they will also lose charge during overcast days, unless you overbuild those panels to maintain the batteries.
Its a struggle to keep the batteries charged even if you don't use them.
Even with all i said you can make solar work its just more then most will want to jump into.
So fair warning.
Best to go small, small battery and 100 watt panel, charge controler and learn from there.
