All the Sun Pro people did mask, when asked, or even before coming in to do the massive work required for this installation. I was so happy with the work, and enjoyed having the workers here. We felt good about helping to keep the economy going during the covid-19 shut downs and quarantines. The salesperson sat outside with me, masked, as was I.

Maybe the nasty reviewer K.M. is confusing SunPro with the many other marketers of solar currently, as it is a trend. Outdoors, masks not as necessary, but Sun Pro staff were uniformly polite, considerate, and competent. I liked that they double-checked and called in to supervisors as they worked.
