Our solar power trailer with fold-out 1 kW solar array and 1,000 pound deep-cycle battery bank has been used to provide electrical power to operate public address systems and    projection video presentations for many outdoor and educational events when utility power was not available, and a generator would be too noisy.  Our most recent request came from Robert Duvall and his wife, who hosted a weekend tent event for over 1000 attendants to their rural Virginia horse farm.
