With a large portfolio of commercial clients, Solar Energy Services has a proven track record in providing customized, turnkey solar solutions to a wide variety of businesses, nonprofits, and government clients in the Mid-Atlantic area. From initial site survey through O&M, SES maintains 100% control over each project – ensuring the most cost-effective, energy-efficient and trouble-free system for each client.


Whether large or small, all solar designs begin with a site survey.   This phase is a vital step in the process as it affects every aspect of the project from design through return on investment.   Onsite visits, in conjunction with aerial imaging tools, are employed to gather site-specific information.
