SolarShade

Privacy shades that generate electricity. Modular photovoltaic window coverings with deterministic safety governance, battery storage, and grid-interactive capability.

The Problem Is Obvious

Every privacy shade, blind, and window covering in every building on earth intercepts solar radiation and converts it into waste heat. That's energy hitting a surface you already own, doing nothing useful.

SolarShade captures that energy. Each shade generates electricity while still providing privacy, glare reduction, and thermal management. It retrofits into existing windows. No construction. No permits for the DC-only version. Hang it like blinds, plug in a USB-C cable, start generating.

Architecture

SolarShade is three integrated systems in one product: a photovoltaic generator, a power conditioning system, and a deterministic safety controller.

PV Shade Assembly
Flexible CIGS thin-film cells bonded to aluminum slats with bypass diode protection. ETFE encapsulation for UV resistance. Modular — individual slats are field-replaceable without disassembling the headrail.
Headrail Controller
ESP32-based monitoring with dual INA219 current/voltage sensors, triple DS18B20 temperature sensing, and rotary encoder slat-angle tracking. WiFi dashboard at 192.168.4.1 for real-time monitoring.
MPPT Power Path
Genasun GV-5 maximum power point tracking. LiFePO4 battery storage with integrated BMS. USB-C PD output supporting 5V through 20V at up to 100W. Physical disconnect switch with hardware interrupt.
Grid-Interactive Path
Future stages add a certified microinverter for AC grid connection. Zero-export mode via CT clamp monitoring. Anti-islanding protection. Branch-circuit limiting. All governed by the deterministic safety engine.
Thermal Value Engine
Intercepting solar radiation at the window reduces cooling demand by 25-75%. In many installations, the HVAC savings exceed the electrical generation value. A 12-window home saves ~$900/yr in cooling costs alone.
Building-Scale Mesh
Multiple shades coordinate through a building controller. A 200-window commercial tower generates $43,816/yr in combined electrical and HVAC savings with a 3.4-year payback period.

Energy Path

Every watt follows a deterministic path from photon to load. No ambiguity. No uncontrolled switching.

PV Shade Assembly (6x CIGS cells, 18V nominal) ↓ Fused DC Bus (5A blade fuse, XT30 connector) ↓ Physical Disconnect (DPST 30V 10A, GPIO interrupt) ↓ Safety Relay (N.O. — opens on fault, power loss) ↓ INA219 Monitoring (voltage + current, I2C → ESP32) ↓ MPPT Controller (Genasun GV-5, LiFePO4 profile) ↓ ┌───────────────┬────────────────────┐ ↓ ↓ ↓ LiFePO4 Battery USB-C PD Output Future: Inverter 12.8V 6Ah 5/9/12/15/20V AC grid export (76.8 Wh) (up to 100W) (certified only)

Deterministic Safety Governance

SolarShade uses the same deterministic governance architecture as Lume-V and the Meridian Canon. An AI system may optimize comfort and energy production, but it does not have final authority over safety-critical switching. These nine rules are architecturally enforced and cannot be overridden by software, firmware updates, or remote commands.

1
NEVER export power unless export is explicitly authorized AND the inverter is certified
2
NEVER energize grid wiring during a utility outage
3
NEVER exceed the configured branch-circuit power limit
4
NEVER charge or discharge outside the BMS safe envelope
5
ALWAYS disconnect within 2 seconds on anti-islanding trip
6
ALWAYS shut down on arc fault, ground fault, or isolation failure
7
ALWAYS fail to SAFE_IDLE when sensor data is missing or inconsistent
8
ALWAYS preserve a signed, append-only audit trail of every state transition
9
NEVER allow an AI optimization layer to override rules 1 through 8

PV Material Comparison

Four photovoltaic technologies evaluated for shade integration. CIGS is the Stage 1 baseline — it balances efficiency, flexibility, and durability for a moving-surface application.

Material Efficiency Flexibility Weight UV Life Cost/Wp
CIGS (Flexible) 18% Excellent (25mm bend) 1.0 kg/m² 25 years $0.60
Monocrystalline (Rigid) 22% None 10.0 kg/m² 25 years $0.28
Organic PV (OPV) 8% Excellent (5mm bend) 0.125 kg/m² 7 years $0.45
Amorphous Silicon 8% Good (50mm bend) 1.5 kg/m² 20 years $0.75

Building-Scale Projections

Conservative engineering estimates. Real-world output will be 10-20% lower due to partial shading, temperature effects, aging, and non-optimal slat angles. These are baselines, not marketing projections.

Zero soft costs. No contractor. No permit. No structural engineering. No electrical inspection. SolarShade installs like blinds — mount the headrail, plug in a cable. The installed cost is the product cost. Traditional solar spends 60-70% of total project cost on installation labor, permitting, and engineering. SolarShade eliminates that entire layer.

Building Type Windows Install Cost Annual kWh Annual Savings Payback
Home (Interior) 12 $5,988 ~1,750 $1,163/yr 5.1 yr
Home (Exterior) 12 $5,988 ~3,180 $2,997/yr 2.0 yr
Apartment 6 $2,994 ~875 $608/yr 4.9 yr
Small Office 20 $8,980 ~2,920 $1,909/yr 4.7 yr
Commercial Tower 200 $69,800 ~53,000 $43,816/yr 1.6 yr
📊
Pricing: $499/window (residential) · $449 (small commercial) · $349 (volume 50+). These are total installed costs. No electrician. No permit fees. No engineering review. Traditional rooftop solar averages $2.50-4.00/W in hardware plus $1.50-3.00/W in soft costs — SolarShade collapses the entire soft-cost stack to zero.

vs. Traditional Solar

Rooftop solar payback periods already include the 30% federal Investment Tax Credit. SolarShade's numbers below are pre-incentive — no tax credits factored in.

Traditional Rooftop SolarShade
Residential Payback 8–9 years 2.0–5.1 years
Commercial Payback 5–7 years 1.6 years
Apartment / Renter Not possible 4.9 years
Permits Required Yes — electrical, structural, interconnection No (DC-only, SELV)
Licensed Electrician Required Not required
Structural Engineering Required (roof load analysis) Not required
Installation Time 1–3 days (professional crew) 30 minutes per window
HVAC Savings None — panels don't shade windows $75–187 per window/yr
Portable No — permanently attached to roof Yes — take it when you move
Soft Costs (% of total) 60–70% 0%
Zero Soft Costs
Traditional solar spends $1.50–3.00 per watt on permits, labor, engineering, and inspections — often exceeding hardware costs. SolarShade's installed cost is the product cost. Mount it like blinds. Plug in a cable. Done.
Dual Revenue Stream
Rooftop panels generate electricity but don't reduce cooling loads — they sit on the roof while the sun beats through your windows. SolarShade intercepts solar radiation at the glass, producing electricity and cutting HVAC costs simultaneously. In commercial buildings, HVAC savings are 6x the electrical value.
Markets That Don't Exist
115 million US renters can't install rooftop solar. Neither can apartment dwellers, office tenants, HOA-restricted homeowners, or historic buildings. SolarShade is the only solar product available to these markets — not a better option, the only option.

Meridian Integration

SolarShade's wired product ships first. The next generation integrates with the Meridian Canon — DarkWave's deterministic wireless energy routing architecture — to eliminate all internal wiring between shade headrails and the building controller.

Headrail → Anchor Node
Each SolarShade headrail becomes a Meridian transmitter node. PV energy routes wirelessly through mathematically invariant field paths to a room-level receiver.
Zero Wiring
No cable runs from windows to controller. Mount the shade. Mount one receiver per room. The Meridian field geometry handles everything between them.
Building Mesh
Room receivers connect into a building-scale anchor mesh. Every watt is routed deterministically — same path computation, same safety envelopes as the Meridian Canon specification.
Trust Layer Audit
Every energy transaction — window X generated Y watts at time Z through path W — is recorded on the Fractal Ledger with cryptographic proof. Multi-tenant billing and utility reporting built in.
Three-layer IP stack. Energy harvesting (SolarShade) + wireless routing (Meridian Canon, US Pat. App. 64/032,339 · 64/056,378) + deterministic governance (Lume-V). No competitor holds all three layers. The combined architecture creates a moat that grows with each installation.
