Detailed Profile

Solartime USA is a dedicated solar energy company headquartered in Richardson, Texas, serving the Dallas-Fort Worth metroplex since 2009. Founded by Paul Mierzwa after he encountered solar technology at a German trade show, the company has grown into one of the most active residential and commercial solar installers in the state, with more than 32,000 installations completed. That volume of project experience — among the highest of any Texas-based installer — provides practical knowledge about North Texas roof conditions, utility interconnection procedures, and equipment performance that newer competitors have not yet accumulated.

The company holds NABCEP certification, the gold standard for solar professionals in the United States. NABCEP-certified installers have demonstrated competency through rigorous examination and documented field experience, signaling that design and installation practices meet or exceed national best practices. Solartime pairs this credential with premium equipment including Qcells, Silfab, and Panasonic panels alongside Enphase microinverters — a combination that prioritizes long-term reliability and per-panel optimization over lowest upfront cost.

Texas presents one of the most dynamic solar markets in the country, and the DFW area has seen explosive growth in residential adoption as electricity costs have climbed. Solartime has operated in this market long enough to have navigated multiple utility rule changes, equipment technology cycles, and permitting updates, giving them an operational fluency that translates directly into smoother project timelines. Their team handles the full lifecycle from consultation and roof assessment through engineering, permitting, installation, inspection, and utility activation.

Solartime's perfect 5.0-star Google rating from 323 reviews is backed by an A+ BBB rating. Customers consistently cite thorough pre-installation site surveys, professional installation crews, and responsive post-installation support. The company also provides monitoring dashboards that allow homeowners to track system performance in real time, an offering Solartime was among the earlier Texas installers to implement.

Solartime USA earns the number 2 ranking in Texas with a composite score of 84.5 out of 100 in our evaluation methodology.
