How long does it take to charge a 36V 16aH battery with this?
I would imagine it takes about a million years if ever - especially in Ireland.
Hi Phil,
not at all!!
I am using a Golden 250W Minimotor in a frontwheel. Distance to work ist 28km and I need ~ 150Wh from my two 2Ah Bosch fat battery packs. Assuming that you use your bike from March to Oktober you will get a solar radiation of ~ 3kWh/m²d in Dublin.
3kWh/m²d : 1000W/m² STC conditions = 3h/d of the peak power from a solar modul.
150Wh/d : 3h/d = 50W, losses of 15% --> solar module size = ~ 57Wp or bigger
A 60 to 80Wp solar module will deliver enough energy to charge the battery during day time.
I hope Golden Motor is going to sell their solar charge controller seperately, that would be a very nice option!
