What Mars Energy Group does

Mars Energy Group (legal entity A2B Development, LLC) is a Rocklin, California-based holding company that acquires and incubates renewable energy operating businesses, then centralizes systems, capital, and talent to grow them. Founded in 2016, the company employs 11-50 people at its corporate level but operates through at least 11 wholly-owned subsidiaries, including core EPC arm MARS Energy Solutions, builder-focused MARS Builder Solutions, residential builder subsidiary Solara Home Energy, and operational units spanning community solar development (Landmark Power), energy credit brokerage (Envest Energy), public works (Unified), non-profit/school PPA financing (K12 Energy), and operations/maintenance (SolarCare+).

The company delivers commercial-scale solar EPC services nationwide — engineering, procurement, and construction for ground mount, carport, and rooftop solar installations, paired with battery energy storage and EV charging infrastructure. Project sizes range from 73kW up to a 15MW community solar portfolio, with named deployments at government facilities (corrections, school districts, prisons, airports), commercial enterprises (wineries, dairies, manufacturing, senior care), and production homebuilders. The technology stack includes NABCEP-certified workforce, master electricians, PMP-certified project managers, Tesla-certified and ChargePoint-certified installation credentials, OSHA30 safety certifications, and the Ready Home Energy platform — a workflow automation system routing tasks to appropriate department queues in new homebuilder contexts.

Revenue is generated through multiple streams: project-based EPC contracts, recurring O&M service contracts via SolarCare+, Power Purchase Agreement (PPA) structures (especially for tax-credit-locked non-profits and schools), project financing facilitation through lender relationships, and transaction-fee REC brokerage. The go-to-market is enterprise field sales leveraging "Request a Bid" consultations across specialized customer-segment funnels (developers, government, commercial builders, residential builders, agriculture, non-profits/schools, landowners). Distribution runs through direct regional sales teams plus retained subsidiary brands operating in their legacy markets under the consolidated MARS Energy umbrella.

Revenue model

1. EPC Services: Engineering, procurement, and construction services for commercial solar projects. Revenue generated through project-based contracts for ground mount, carport, and rooftop solar installations, including energy storage and EV charging.
2. Project Development: End-to-end development services including site analysis, custom system design, permitting, and interconnection. Revenue from development fees and project delivery.
3. Operations and Maintenance (SolarCare+): Ongoing maintenance and monitoring services for installed solar systems. Revenue generated through service contracts with regular maintenance schedules and 24/7 monitoring.

5. Power Purchase Agreement (PPA): Zero out-of-pocket financing option where customers pay for energy generated at predetermined rates. Popular with non-profits and schools with no upfront cost or long-term maintenance responsibilities.
6. Project Financing: Facilitated financing through established lender relationships. Company works with customers to review portfolios and determine optimal financing solutions.
7. Acquisition Integration Services: Company acquires renewable energy companies, providing capital, technology, systems implementation, and process improvements. Revenue from integrated operations of acquired subsidiaries.

Direct peers

• SOLV Energy: One of the largest US commercial and utility-scale solar EPC contractors; competes head-to-head for similar commercial, government, and community solar EPC bids across many of the same states.
• Swinerton Renewable Energy: Direct competitor providing utility-scale and commercial solar EPC services with self-perform construction capabilities and a national footprint, overlapping with MARS's target project profile.
• McCarthy Building Companies: National EPC contractor with a strong solar and energy storage practice serving commercial, education, and public-sector clients similar to MARS's school district and government portfolio.
• SunPower Corporation: Established US residential and commercial solar installer with Pano AI-style direct-to-homeowner sales and dealer networks, competing for both new-home builder and existing-rooftop segments MARS serves.
• Trinity Solar: National residential solar installer serving new construction and retrofit markets — a comparable channel overlap with MARS's Solara Home Energy and builder-solutions business.
• Adapture Renewables: Developer and EPC of commercial and utility-scale solar plus storage projects with tax-equity capabilities, mirroring MARS's Nelnet Renewable Energy business line and project-development services.

Broad incumbents

• Mortenson Construction: Large national EPC firm with a dedicated renewable energy group executing utility-scale solar and storage projects; comparable in offering but with substantially greater bonding capacity and balance sheet.
• Tesla Energy: OEM and turnkey provider of solar + Powerwall + BESS + EV charging; MARS is a Tesla Certified Installer partner, and Tesla Energy competes for similar commercial energy and storage projects at larger scale.

Regional players

• Baker Electric Solar: California-based residential and commercial solar EPC with self-perform installation and O&M services, directly comparable in geography, customer segments, and service mix to MARS.

Emerging players

• Energix: Solar developer with EPC and asset management for community and commercial projects in multiple US states; comparable business model and customer base despite a smaller operating scale.
