Technology brief
is a new-generation solar thermal panel that harnesses heat (infrared) from sunlight—not visible light—to generate electricity directly via thermoelectric conversion.
The challenge
Primary use cases: distributed solar power generation (households, farms, remote sites); supplementary grid power; off-grid operations; industrial heating + power (combined thermal/electric); arctic/polar regions (IR from even distant sun).
Industries and users: utilities, renewable energy operators, remote communities, industrial facilities, emergency/disaster response.
Scale: modular panels (1–10 kW) to utility-scale installations (MWh+).
ARBOK solution
ThermaVolt is a new-generation solar thermal panel that harnesses heat (infrared) from sunlight—not visible light—to generate electricity directly via thermoelectric conversion. Achieves ~80 % efficiency compared to photovoltaic (20–25 % typical). Operates continuously and effectively under cloud cover and low-light conditions (IR penetrates clouds). No moving parts; solid-state operation. Deployable globally regardless of latitude or season; generates power 24/7 relative to solar IR availability. Represents paradigm shift in solar energy generation beyond conventional PV.
Sunlight contains ~52 % infrared (heat) energy. ThermaVolt panels capture this IR spectrum via specialized absorber coating. Thermal energy is converted to electricity via thermoelectric effect (Seebeck effect) using integrated solid-state converters—no mechanical turbines or moving parts. Output voltage/current directly proportional to IR intensity. Efficiency: ~80 % (thermal IR → electrical); far exceeds PV ~20–25 %.
Market and application
Solar energy: $200B+ global annual market. ThermaVolt's superior efficiency and all-weather performance positions it to capture 5–15 % market share over 10 years = €10–30B addressable opportunity. Particularly strong in emerging markets and off-grid applications.
CAPEX: €300–500 per kW installed (vs. PV €400–600/kW); similar or lower cost.
Output: 1200–1800 kWh/m²/year (vs. PV 1000–1200 kWh/m²/year); 20–50 % higher.
Levelized cost: €50–80/MWh (comparable or better than PV + wind).
Payback: 4–7 years typical; strong IRR.
Use cases
Primary use cases: distributed solar power generation (households, farms, remote sites); supplementary grid power; off-grid operations; industrial heating + power (combined thermal/electric); arctic/polar regions (IR from even distant sun).
Industries and users: utilities, renewable energy operators, remote communities, industrial facilities, emergency/disaster response.
Scale: modular panels (1–10 kW) to utility-scale installations (MWh+).
Steps: site assessment (IR availability) → panel sizing (power requirement) → mounting (roof, ground, tracking frame) → electrical connection (inverter, battery, grid) → autonomous operation. Maintenance: annual cleaning (remove dust/dirt from absorber surface).
Standalone grid-independent power (off-grid + battery); integrates with thermal storage (hot water); pairs with conventional PV for hybrid solar systems; combines with building HVAC for heating + power.

Efficiency: ~80 % (IR-to-electrical conversion).
Power density: 150–300 W/m² under typical solar IR flux.
Operating temperature: ambient to +80 °C (panel surface); passive cooling.
Weather performance: effective in cloud cover, rain, snow (IR penetrates).
Lifespan: 25–40 years (solid-state, no degradation pathways like PV silicon).
Thermal output: can also provide heating (dual thermal/electric output option).
Voltage/current: scalable via panel series/parallel connection.
IR-absorber coating (proprietary); thermoelectric conversion layer (Seebeck junctions); thermal spreader (copper, aluminum); electrical terminals; mounting frame; optional thermal tap (hot water output). Modular panel design; weatherproof enclosure.
Technical: 80 % efficiency (3–4× PV); works in cloud/low-light; no degradation over time; solid-state (no mechanical wear); dual thermal+electric possible.
Economic: higher power per m² vs. PV (smaller installations for same output); 25–40 year lifespan reduces replacement cost; works in latitudes/seasons where PV underperforms.
Environmental: zero emissions; no hazardous materials (unlike some PV); fully recyclable at end-of-life.
Geographic: deployable globally—arctic, tropics, high-altitude—due to IR availability 24/7 (relative to Earth's thermal radiation at night).
