Solar Industry Expert

Andy is arguably the most qualified rooftop solar expert in America. He is in a unique position, having founded a large solar company but now being independent of any particular company. He has appeared on CNBC, has been referenced in public hearings concerning the rooftop solar industry ( such as the recent CPUC NEM 3 decision) and has been referenced by many major publications such as the Wall Street Journal, Business Week and many others.

Andy Sendy is a well known and trusted figure within the solar industry with more than 15 years of experience.

His video reviews of the leading brands of solar panels and home energy storage batteries are a must watch each year for both homeowners and solar industry professionals alike.

In 2021, an article he wrote about a clause in the Tesla solar panel rental contract caused Tesla to change this clause within days.

He was the founder of Solar Wholesalers, now the largest solar panel installation company in South Australia, has owned and operated solar projects in Japan and is Chairman of Solar Investments, a company that publishes several of the best rooftop solar related consumer education websites in America.

Andy has sat across the kitchen table with thousands of people who have considered solar. His background as a corporate lawyer and a financial analyst gives him a unique insight into the information consumers need.

His special skill is his ability to identify criteria that homeowners can use to determine the difference between good and bad solar companies
