Hi all, I know nothing about this firm--but the prices appear to be low: https://www.santansolar.com/?fbclid=IwAR17Xx_DhkB3h13BFmTjqejxTlf92ZO7UsVEAiNjNmcyNzrOkJx9XgYN26c
The company sells a 250 watt with 20 amp mppt controller for $165. Considering my system was $1700.00 in 2005 it is a heck of a deal.
They also have some larger 50 amp mppt controllers sold in a kit for a few dollars more. That is what I'd advise, as they can add some panels that way.
Goodness knows whether the controller or panels are great, poor, or bad.
