Yes, a solar mounting system can still be used in areas with limited access to power purchase agreements. While power purchase agreements (PPAs) involve buying electricity from a third party, a solar mounting system can be used for self-consumption of generated solar power in such areas. This allows individuals or businesses to reduce their reliance on grid power and generate their own electricity, even without a PPA. Additionally, excess solar energy can be stored in batteries for later use, further enhancing energy independence in areas with limited access to power purchase agreements.
