Supporters of solar energy rallied in downtown Tucson Monday morning to protest Tucson Electric Power's solar fee proposal.
TEP is proposing an additional charge of $20 for solar customers, while reducing the amount of money credited to those customers for electricity sent back to the grid.
Organizers of the rally say they have more than 6,000 signatures they plan to send to the Arizona Corporation Commission.
Similar protests happened in Phoenix, as Arizona Public Service proposed a fee increase. The company decided to charge solar customers an additional $6.50.
