Project SUN turns stranded residential solar capacity — capped by regulation, not physics — into a decentralized, carbon-negative AI compute mesh. No transmission queue. No new substation. Just the 65–80% of your roof that utilities won't let you use.
Centralized data centers are colliding with transmission queues, water limits, and thermal physics — right as inference, not training, becomes the dominant and permanent energy load.
California's Net Billing Tariff (NEM 3.0) sizes solar interconnects to your home's historical consumption, not your roof's physical collection area — leaving most of a typical rooftop's solar potential unbuilt for its entire 25–30 year lifespan.
| Metric | Regulatory-capped (NEM 3.0) | Max. physical build-out |
|---|---|---|
| DC nameplate capacity | 6.36 kW-DC | 30.53 kW-DC |
| Annual generation | 10,800 kWh | 51,840 kWh |
| Mid-day export value | $0.04 – $0.08/kWh | $2.15/kWh (as compute) |
| Simple payback period | 12.4 years | 2.78 years |
| Internal rate of return | — | 32.8% |
A wall-mounted, 1.0–2.5 kW appliance built on four pillars — engineered so a property owner hosts real revenue-generating compute without ever being able to see what runs on it.
TPM 2.0 / HSM hardware root of trust, plus AMD SEV-SNP, Intel TDX, or ARM CCA trusted execution environments. Model weights, prompts, and outputs stay encrypted end-to-end — the host cannot inspect or tamper with a workload.
Chassis micro-switches, conductive mesh wiring, and MEMS accelerometers trigger instant cryptographic key zeroization on intrusion — drilling, cutting, or unauthorized access wipes the enclave before it can be read.
No physical or logical link to the resident's home LAN. Traffic moves exclusively over an encrypted WireGuard mesh with 5G/LTE failover — a dedicated, air-gapped path in and out.
Direct-to-chip liquid cooling recaptures 85–92% of electrical input as usable thermal heat for domestic hot water — targeting a net-negative PUE and zero evaporative water consumption.
| Spec | Value |
|---|---|
| Power budget | 1.0 – 2.5 kW continuous, 80 Plus Titanium PSU |
| Acoustic output | < 30 dBA at 1 meter, peak load |
| Compute silicon | Dual/quad FP8 · INT4 accelerator blades, HBM3e / LPDDR5X |
| Compliance | UL 62368-1 · NFPA 70 · SOC 2 Type II · ISO 27001 · HIPAA · GDPR |
kWh consumed are pegged directly to tokens generated. Enterprises buy carbon-neutral inference at a steep discount; hosts get paid in cash and free hot water; the grid gets a shock absorber.
| Stakeholder | Economic benefit |
|---|---|
| Compute buyer | Dynamic rates ~$0.001–$0.002 / 1k tokens — a 40–60% discount vs. hyperscalers |
| Host property owner | 100% grid-energy reimbursement + 15–25% net margin share + free hot water |
| Node operator | 14–18 month simple hardware payback period |
| Protocol & DAO | 5–10% transaction fee funding insurance, development, and governance |
An Ethereum L2 settles multi-party payments trustlessly; off-chain state channels stream per-token, per-kWh micro-payments with sub-cent fees, batched into 15-minute settlement epochs.
