What are the main challenges to  solar panel adoption ?


assistant
Based on our collective understanding , main barriers to residential solar panel adoption are Economic, Policy and legal, and technical. For example, the initial cost of homeowner to invest in solar, is substantial and the break even on the investment is over 20 years. In addition many utilities don’t have policies to sufficiently compensate for storage and reselling of the excess energy produced.
