Southeast Energy Resources holds a strong 4.5-star rating from 15 reviews. Customers commend their professional installation and customer service, making them a reliable choice for solar panel installations. However, some feedback indicates longer wait times for project completion. This company is best for homeowners seeking experienced installers in Summerville.

It serves Summerville, SC and surrounding areas, with $15,000 to $30,000 pricing, and the honest trade-offs are longer wait times reported and limited service offerings.
