What Miller Bros Solar does
Miller Bros Solar is a US independent solar and energy storage operations and maintenance (O&M) service provider headquartered in Conshohocken, Pennsylvania. Founded in 2012 by Ryan Hoffman, the company entered the commercial O&M market with its first customer portfolio and has since expanded into utility-scale and energy storage O&M. It manages 5.5 GW DC of solar capacity across 250+ sites in 23 states and 5 GWh of contracted energy storage services, ranking among the top five US solar O&M providers. Customers include utility-scale solar asset owners, commercial and industrial (C&I) solar fleet operators, and energy storage asset owners.
The company delivers service through four product lines: Utility O&M (projects ranging from 20 MW to 485 MW DC, including GO, GOP, and CIP services), Commercial O&M (24/7 Operations Center support, warranty management with 24-hour response times, and performance optimization), Tech Services (commissioning, repowering, incident recovery, end-of-warranty inspections, and drone-based DC health inspections), and Energy Storage O&M (preventative maintenance, BOP/POCC repairs, HVAC, and fire suppression). Underpinning these is a 24/7 NERC-registered Remote Operations Center with embedded cybersecurity, operating in 5 of 6 NERC regions and providing monitoring, equipment analytics, and compliance reporting across the fleet.
The business model is enterprise B2B managed services plus professional services, with services sold through direct field sales and Business Development outreach to solar asset owners and their corporate customers. Pricing is quote-based and tailored to individual project or portfolio needs rather than publicly disclosed. Revenue is generated primarily through recurring multi-year O&M contracts, supplemented by episodic technical services (commissioning, repowering, incident recovery, end-of-warranty work) and the emerging energy storage service line. The company also markets certifications as a Tier-1 inverter service provider across multiple OEMs and emphasizes a zero-incident safety culture.

Miller Bros Solar competitors and assessment
Company assessmentDirect peers
- SitelogIQ: Provider of operations and maintenance services for distributed energy and solar portfolios. Directly comparable to Miller Bros in delivering recurring managed O&M services to commercial and institutional solar asset owners.
- SOLV Energy: One of the largest US solar EPC and O&M providers following its acquisition of Swinerton Renewable Energy. Directly comparable to Miller Bros Solar in operating utility-scale and C&I solar O&M fleets with national field service coverage.
- NovaSource Power Services: Independent solar O&M specialist operating multi-GW fleets across the US. Closely comparable to Miller Bros in service mix (utility-scale O&M, performance engineering, and storage services) and in competing for the same asset owner RFPs.
- Borrego Solar: Solar developer and EPC with a dedicated O&M division serving C&I and utility-scale customers. Comparable to Miller Bros in providing multi-state managed O&M services to commercial and utility solar asset owners.
- DEPCOM Power: US solar operations and maintenance provider with utility-scale and C&I fleet coverage. Overlaps directly with Miller Bros on managed O&M services, NERC compliance support, and technical services for solar asset owners.
Broad incumbents
- Clearway Energy Group: Major US renewable asset owner and operator with in-house O&M capabilities. Comparable as a large-scale operator of utility solar and storage fleets that both supplies and competes for O&M labor and best practices.
- First Solar: Vertically integrated solar developer with in-house O&M operations and serial-defect management experience. Overlaps with Miller Bros on utility-scale O&M, inverter-adjacent services, and NERC compliance, and is a known prior employer of several Miller Bros leaders.
- AES Corporation: Global utility and renewable operator with significant US solar and battery storage assets and internal O&M functions. Comparable as a large incumbent that both operates its own fleet and competes in the broader renewable operations and maintenance services market.
- EDF Renewables: Global renewable developer and asset owner with a substantial North American solar O&M footprint, including through DEPCOM Power. Comparable as a broader incumbent that competes for utility-scale O&M contracts and offers overlapping capabilities at scale.
Emerging players
- Pine Gate Renewables: US solar developer and operator with growing utility-scale fleet and in-house O&M. Partially overlapping with Miller Bros in operating utility-scale solar and storage assets, but primarily a developer-operator rather than a pure independent O&M provider.
