Solar & Storage
A 2.01 MW-DC solar array paired with a 6 MWh battery system at a large commercial property in Santa Rosa — developed and engineered by Surya and POWERFLOW. The system features a DC-coupled architecture, pairing the solar array directly with the battery at the DC level for maximum round-trip efficiency and reduced conversion losses. Designed for both demand charge reduction and full resilience, operating behind a PG&E transmission-voltage account on a Direct Access tariff.
Retreat Center
Microgrid development and full-scope engineering for a 120-acre Tibetan Buddhist retreat center in the Sonoma County redwoods. A 170 kW solar canopy — mounted over an entire senior residential care building — pairs with a 550 kWh Kore Power BESS and an integrated 500 kVA diesel generator for seamless whole-campus backup. Delivers $40K/yr in utility savings and a meaningful cut in diesel consumption.
Lakeside VPP
Virtual Power Plant demonstration project serving a disadvantaged community in Goleta, CA. 25 residential homes each equipped with 10 kW solar and 40 kWh battery storage, communicating together as a single coordinated VPP with grid-aware DERMS orchestration.
Youth Camp Solar
167 kW solar PV system under a 20-year Power Purchase Agreement for a youth camp facility. Full financial modeling, engineering design, and ITC/IRA optimization — locking in clean energy at below-market rates for two decades with no upfront capital from the client.
Ecology Center
125 kW solar + 540 kWh battery storage microgrid serving an 80-acre organic farm, nonprofit education center, and onsite residential community in West Sonoma County. System achieves 100% on-site generation with full grid independence during outages — projecting $2M+ in energy savings over 25 years.
Conference Ground
570 kW solar farm paired with a 4.0 MWh iron-sodium battery (Inlyte Energy) at a Tier 3 High Fire Threat Zone facility in Occidental, CA. Backed by a $4.1M DOE Critical Facility Energy Resilience grant, the system will provide up to two weeks of diesel-free backup, serve as a community evacuation center, and support a Russian River Utility water pump station. Currently in development — operational 2027.
Microgrid
Engineering, utility interconnection, construction management, and commissioning for a solar PV + second-life EV battery microgrid at a pediatrics clinic — providing up to 6 days of backup power. Sub-Subrecipient on CEC Award EPC-19-039 under RePurpose Energy Inc., part of a $3M CEC-funded demonstration program.
Project
Full-scope solar carport microgrid for Ceres' new $22M headquarters in Santa Rosa — the only accredited medically-tailored meal provider north of San Francisco. 345 kW solar + 1.56 MWh storage powering a 20,000 sq ft all-electric commercial kitchen and community resilience center. System cuts energy costs by 67% and carbon footprint per meal by over 80%. POWERFLOW delivered the full scope: feasibility study, load forecasting, microgrid business case, and seasonal resilience analysis — followed by $1.2M SGIP grant writing, full-discipline engineering, construction management, and commissioning.
Sebastopol
50 kW rooftop solar paired with 60 kWh battery storage for a Sebastopol hotel — designed as a non-export system to avoid California prevailing wage requirements. POWERFLOW provided full scope: feasibility, critical load selection and isolation design, engineering, construction management, and commissioning. System delivers ~12 hours of critical backup and measurable energy cost savings for ongoing operations.
Center
65 kW rooftop solar across two school buildings in Santa Rosa, each served by its own 60 kWh battery (122 kWh total) — providing ~12 hours of critical backup power per building. Designed as a non-export system to avoid California prevailing wage requirements. POWERFLOW delivered full scope: feasibility, critical load selection and isolation, engineering, construction management, and commissioning. Energy savings were a primary driver for the institution.

Founder
Odisha, India · 13th Century
The name Surya comes from Sanskrit — the Hindu sun god, the source of light and life. That photo behind me is the Konark Sun Temple in Odisha, India, a 13th century structure built as a giant stone solar chariot aligned to the movements of the sun. It is one of the great feats of sacred geometry and astronomical design in human history. Standing in front of it, the thread between ancient reverence for solar energy and the work I do today felt undeniable. The name chose itself.
My technical path began at Santa Rosa Junior College, where a California Energy Commission grant for a campus microgrid system sparked a curiosity that never left me. I went on to earn degrees in Engineering, Mathematics, Natural Sciences, and Chemistry — and a graduate certification in Microgrid Design & Modeling from Arizona State University. Over the past 6+ years in the field, I've developed a track record across solar, battery storage, microgrids, VPPs, and grants — from first site visit through commissioning.
What keeps me in this work is the clients — nonprofits keeping the lights on during wildfires, schools giving students clean air, food organizations cutting their carbon footprint by 80%. The path through plan check, utility interconnection, and grant compliance is rarely simple. That's the job, and I love it.
Surya & POWERFLOW
Built in Sebastopol. Working across Northern California.
Surya Technologies is an energy development firm founded to bring solar, storage, and microgrids to the organizations that need them most — nonprofits, municipalities, campuses, and communities. POWERFLOW is our in-house engineering arm, covering every technical discipline from feasibility through commissioning.
We believe energy infrastructure is community infrastructure. Every project is an opportunity to build a more resilient, equitable grid — and we put our own capital in to prove it.
