Powering the future with solar energy

Blymyer Engineers is a national leader in solar engineering with over 16 GW of engineered plants. Since completing our first solar project in 2003, we’ve engineered hundreds of utility-scale and distributed-generation plants.

Excellence and experience drive our success in solar projects. Having engineered about 15% of the total solar capacity in the United States, we offer electrical, mechanical, structural and civil engineering services for utility-scale and distributed-generation solar systems with end-to-end quality, from energy analysis and modeling through commissioning.

Our optimized designs include a deep understanding of energy economics, including upfront and long-term costs.

Leading the industry in both utility-scale (electricity sold to wholesale utility buyers) and distributed-generation (electricity sold to end-use consumers) solar projects, we are also a primary provider to the California Division of the State Architect, having helped develop the first pre-approved design of solar parking canopies for schools, a protocol that is still used today.

Capturing the energy of the sun is only part of the system, however. Blymyer also provides expert substation and energy storage (BESS) design to ensure grid reliability and provide backup energy for critical enterprises.
