What 77 Sol does
77Sol (legal entity 77 SOL TECNOLOGIA S.A.) is a Brazilian solar energy digital marketplace founded in 2020 and headquartered in São Paulo. The company operates a two-sided platform that connects solar installation integrators with end customers (residential and commercial) seeking solar projects, providing an integrated stack of tools including equipment quotations, automated project proposal generation, financing facilitation, insurance options, and project management. The platform is offered free of charge to the integrator side, with the integrator portal ("Área do Integrador") and the customer-facing "Economize" simulator forming the two primary user surfaces.
The business model is a take-rate marketplace monetized through three streams: (1) financing facilitation fees via integrated credit partners QI Sociedade de Crédito Direto S.A. and QI Caas Ltda., enabling pre-approved credit decisions in under two minutes with installment structures aligned to electricity-bill savings; (2) commissions on equipment transactions flowing through the integrated equipment-manufacturer marketplace; and (3) insurance product commissions. The platform serves a long-tail base of 29,000+ integrator partners across all Brazilian states, with no platform subscription fee for integrators — a deliberate community-led go-to-market choice that prioritizes network growth over per-seat monetization.
The company is venture-backed, having closed a R$14 million (~$2.7M USD) second funding round in February 2023 led by Crescera Capital and EDP Brasil's corporate venture arm (EDP Ventures). Operations span a single country (Brazil) with 51–100 employees. Distribution combines self-serve digital (websites including 77sol.com.br, economize.77sol.com.br, and acesso.77sol.com.br), integrator-partner referral, industry-event presence (notably Intersolar), and earned media in tier-1 Brazilian outlets (Forbes, Veja, Folha, Exame, Terra). Founder and CEO Luca Milani received Forbes 30 Under 30 recognition in 2023.

77 Sol competitors and assessment
Company assessmentDirect peers
- Mosaic: Mosaic is a US solar financing platform that provides loan products for residential solar projects through an installer network. Its combination of installer marketplace and integrated financing parallels 77Sol's QI SCD-powered model, though Mosaic is financing-first rather than integrator-tools-first.
- EnergySage: EnergySage is a US solar marketplace connecting consumers with vetted installers, providing quotes, financing information, and educational content. It is the closest international analog to 77Sol's consumer-side marketplace model, although 77Sol goes further with embedded financing and an integrator SaaS portal.
- Pick My Solar: Pick My Solar operates a US online solar marketplace that aggregates installer bids for consumers and provides financing options. Its online quote-comparison flow mirrors 77Sol's Economize simulator experience.
- GoodLeap: GoodLeap (formerly Loanpal) is the largest US residential solar and home improvement finance platform, originating point-of-sale loans via a large installer network. Its scale-driven, partner-led financing model closely resembles the role 77Sol plays in Brazil via QI SCD.
- Solfácil: Solfácil is a Brazilian solar fintech that provides integrated financing to integrators and end customers for distributed generation projects. It is a direct competitor on the financing-facilitation side of 77Sol's offering within the same Brazilian market.
- Portal Solar: Portal Solar is a Brazilian solar marketplace and content platform connecting consumers with integrators and providing quotes, financing information, and educational content. It is 77Sol's most direct Brazilian competitor on the consumer-facing demand-generation side.
- Sunlight Financial: Sunlight Financial was a US fintech specializing in residential solar loan origination through contractor and installer channels. Its point-of-sale financing distribution model maps directly onto 77Sol's financing-facilitation revenue stream, though Sunlight's challenges also highlight execution risk in this category.
Broad incumbents
- Enphase Energy: Enphase is a global leader in solar microinverters and home energy systems (batteries, EV chargers), and increasingly offers financing and installer enablement. It overlaps with 77Sol on the equipment and installer side of the solar ecosystem but as a much broader hardware-led incumbent.
- Sunrun: Sunrun is the largest US residential solar installer with a vertically integrated leasing/financing/PPA model. It is a broader incumbent that combines installation and financing, encroaching on the territory 77Sol addresses via partners, but with a fundamentally different ownership model.
Regional players
- BlueSol: BlueSol is a Brazilian solar energy platform offering design, quotation, and project-management tools for integrators alongside educational content for consumers. It overlaps with 77Sol's integrator-tools proposition (quotations, proposals) in the same Brazilian market, though with less financing depth.
