SunSystem Technology

What SunSystem Technology does

SunSystem Technology (legally SST Construction LLC) is a U.S. operations and maintenance (O&M) provider for distributed solar energy assets, founded in 2008 and headquartered in Rancho Cordova, California. The company runs three integrated service lines: Commercial O&M for utility- and commercial-scale PV plants, Residential O&M for long-term portfolio maintenance, and Home Solar Service for individual homeowner repair and troubleshooting. SST serves PV solar asset management companies and portfolio owners on the commercial side, residential homeowners with owned or financed solar systems, and solar finance providers who need reliable long-term service to protect portfolio financial health.

The company's technical platform centers on field service operations rather than software. Core capabilities include a proprietary 200-point preventative maintenance checklist, FAA-certified drone inspection with thermal imaging and licensed mapping software, custom-built SCADA solutions capable of responding to automatic generation control signals, and DAS monitoring and troubleshooting. All field technicians are OSHA 10 and/or OSHA 30 certified, and the company has resolved over 50,000 residential service issues across a national footprint of 14 U.S. states supported by distributed warehouse locations for equipment management.

SST's business model is professional services-driven. Commercial O&M revenue flows through ongoing service contracts (subscription-style monthly billing) with portfolio owners, while residential service revenue is generated per engagement with quote-based pricing, a 50% deposit to schedule repair work, and the balance due on completion. The company markets directly via website contact forms, segmented by service line, and through an Instagram presence, positioning itself as "the solar industry's leader in third-party servicing." In 2025, SST reported approximately $14 million in revenue, and in May 2026, Otovo ASA (OSEBX: OTOVO) signed a non-binding letter of intent to acquire SST for $770,000 cash at closing plus up to $1.3 million in a three-year earn-out, representing Otovo's seventh acquisition since its December 2025 merger.

Core offering

SunSystem Technology provides operations, maintenance, and repair services for distributed solar energy assets across the United States. The company's three service lines are Commercial O&M (monitoring, preventative maintenance, corrective action, drone services, SCADA solutions, and DAS monitoring for utility- and commercial-scale solar plants), Residential O&M (long-term portfolio maintenance for residential solar systems), and Home Solar Service (direct-to-homeowner troubleshooting and repair on a three-step submit-schedule-repair process).

Product overview

SunSystem Technology (SST) is a U.S.-based provider of operations and maintenance services for distributed energy assets, operating as a solar service company rather than a software platform. The company offers three interconnected service lines: Commercial O&M for commercial and utility-scale solar power plants, Residential O&M for long-term portfolio maintenance, and Home Solar Service for individual residential repair and troubleshooting. The services are unified by shared capabilities including a national technician network, warehouse infrastructure for equipment management, drone technology for site evaluation, SCADA solutions, and quality assurance processes. In 2025, SST generated approximately $14 million in revenue and operates across 14 U.S. states. The company was acquired by Otovo in 2026 as part of Otovo's strategy to build a scaled solar service and maintenance platform integrating acquired operators into the Endurance AI platform.

Direct peers

• Otovo ASA: Norwegian-listed residential solar subscription and services company that is acquiring SST as part of its serial solar-services roll-up. Otovo operates the same third-party solar service model SST does, making it the closest direct peer and now parent platform.
• Borrego Solar: U.S.-based solar EPC and O&M provider with multi-state commercial and utility-scale operations and maintenance offerings. Direct competitor to SST's Commercial O&M line, with similar preventative maintenance and monitoring services.
• GreenLogic Energy: Northeast U.S. solar EPC and service company offering residential and commercial solar installation, monitoring, and O&M. Direct competitor in residential service and repair work.
• Sentinel Solar: U.S.-focused third-party solar operations, maintenance, and repair provider serving both commercial portfolios and residential systems. Closely comparable business model and customer segments to SST.
• Pivot Energy: U.S. community and commercial solar developer that bundles asset management and O&M services for its own portfolio and third-party owners. Comparable to SST in commercial-side recurring service contracts.

Broad incumbents

• Sunrun: Largest U.S. residential solar installer with an in-house service and maintenance operation. While primarily an installer/finance provider, it offers the same residential service functions SST performs and represents a vertically integrated alternative to third-party O&M.
• Enphase Energy: Dominant U.S. microinverter and energy management equipment manufacturer whose Enlighten cloud platform increasingly bundles monitoring and service. Represents a technology-stack incumbent adjacent to SST's SCADA/monitoring work.
• SunPower: Established U.S. residential and commercial solar provider offering installation, monitoring, and ongoing service. Overlaps with SST in residential service and asset management for distributed solar systems.
• Tesla Energy: Vertically integrated residential and commercial solar, storage, and service provider. Broad incumbent that competes with SST indirectly for residential service contracts and adjacent O&M work.

Emerging players

• Radian Generation: Solar asset management and O&M advisory firm focused on commercial and utility-scale portfolios. Comparable to SST's commercial O&M customer base but operates more as an asset-management overlay than a field-service operator.
