What ArchSolar does
ArchSolar is a Portland, Maine-based greenhouse design and manufacturing company founded in 2014. The company designs and fabricates hybrid greenhouse structures integrating proprietary pultruded fiberglass arch construction, structural insulated panel (SIP) walls, multi-wall polycarbonate glazing, light deprivation systems, and renewable energy components. It holds an exclusive partnership for Variable Refrigerant Flow (VRF) and Variable Air Volume (VAV) climate control technology, marketed as reducing HVAC capacity 50-70% and sizing up to 40% versus traditional systems. Core structural products include Gutter Connect, GrowBox (a modular shipping-container-integrated sub-brand), Ground to Ground, and Head House configurations, complemented by add-on modules for climate control, lighting (via TSRgrow), controls and monitoring (via Growlink), and renewables such as photovoltaic arrays and phase change materials.
The company's primary customer segment is commercial cannabis and hemp cultivators, particularly operators in northern climates seeking year-round production and integrated light deprivation. Secondary segments include commercial food and flower growers and urban agriculture operators such as restaurant rooftop installations. ArchSolar runs a consultative enterprise sales motion, guiding customers through a two-stage design process (requirements and initial drawings, then finalized engineering and shop drawings) followed by manufacturing and on-site construction supervision. Revenue is generated primarily through one-time direct sales of structures and systems, supplemented by professional services for design, engineering, and supervision. Customer financing is facilitated through third-party partners offering operational leases, unsecured business loans, and capital leases up to $500k, though ArchSolar does not recognize the financed portion as its own revenue.
The company is founder-led by Tony Kieffer (President and Founder) with a small team of five employees including a Director of Business Development, Operations Analyst, and a Grow Strategies Consultant. Operations are concentrated in Maine with documented projects in New England and Michigan, and a partner ecosystem spanning Growlink, TSRgrow, Ehvert, Modine, Zipgrow, and others. ArchSolar has no disclosed institutional funding and operates as a private, founder-owned business.

ArchSolar product offering
Product offeringCore offering
ArchSolar designs and manufactures hybrid greenhouse structures for commercial growers, with a particular focus on the cannabis and hemp industry. Their structures feature pultruded fiberglass arches, structural insulated panel (SIP) walls, multi-wall polycarbonate glazing, and 50-foot wide clear spans, and integrate climate control, light deprivation, and renewable energy systems. They deliver turnkey projects via a two-stage design and engineering process, with manufacturing and on-site construction supervision included.
Product overview
ArchSolar is a greenhouse design and manufacturing company offering a portfolio of hybrid greenhouse structures and systems. The core product line includes four structural types: Gutter Connect (year-round production with up to 55ft clear spans and 14ft truss height), GrowBox (modular design incorporating shipping containers for workspace, storage, and processing), Ground to Ground (gothic-style for soil farmers with customizable dimensions), and Head House & Utility (integrated or standalone space for processing, extraction, and utilities). These structures share common features: fiberglass arches with low thermal conductivity, multi-wall polycarbonate glazing, SIP wall insulation, renewable energy compatibility, and wide clear spans with high snow/wind load capacity. Supporting the structures are add-on systems including Climate Control (open and closed HVAC with VRF/VAV technology), Light Deprivation (rack and pinion system with Svensson Obscura cloth), Grow Systems (rolling tables, fertigation), Lighting (LED, HPS, Plasma via TSRgrow), Shipping Container Options (C1D1 extraction labs, grow rooms), Renewables (PV arrays, Phase Change Material, Co-Generation), Controls & Monitoring (Growlink integration), and Insulation & Glazing (SIP walls, polycarbonate). Financing options are also available through third-party partners. The company targets commercial growers, particularly in cannabis and agricultural sectors.
