About GN Solar Solutions

Built for the Work Behind Solar

GN Solar Solutions is a woman-founded solar contractor providing comprehensive installation, service, and maintenance solutions for residential and commercial solar projects across Maryland, Virginia, and Washington, D.C.

Who We Are

One team, accountable from planning through long-term service.

Built on a foundation of quality, accountability, and operational excellence, we support homeowners, businesses, and EPC partners with dependable project execution from installation through long-term system service.

Every project is managed with disciplined coordination, clear communication, experienced field teams, and a commitment to workmanship that meets demanding industry standards.

A large share of our volume is field execution for other solar companies and roofing contractors, work that goes out under their brand rather than ours. That is where our crews built their standard, and it is the same standard homeowners get when they hire us directly.

Marleyne Zapata

Marleyne owns and leads GN Solar Solutions. There are no investors and no outside owners, so the standards, the policies and the procedures are hers, and so is the accountability.

She built the company on field execution, delivering installation and service work for other solar brands across the region before opening those same crews up to homeowners directly. That order matters: the operation was proven on volume work for demanding partners first.

She holds the company’s Maryland Home Improvement Commission license (#168849) and works with customers in English and Spanish.
