Solar Mesh

Solar Mesh is an off-grid wireless node in the UniFi Solar Point family, purpose-built for the vast, remote terrain of the American West where grid power is unavailable. The overall form language centers on a single-person installability, paired with solar auto-tracking and 9-hour battery life to achieve optimized energy harvesting in truly off-grid conditions.

• User experience & scenario layout: Integrated solar auto-tracking, with 9-hour battery life to optimize energy harvesting in off-grid environments.
• Form & environmental semantics: A pure geometric volume with a four-sided sloped canopy — not only expressing the product’s functional metaphor, but strategically deterring birds from perching and mitigating heavy ice and snow buildup in harsh outdoor environments.

The design starts by evaluating the real-world feasibility of two wireless technologies — WiFi and LoRa — for precision livestock scenarios, using situational modeling to identify the target user's actual pain points.

• WiFi 2.4GHz option: Signal range limited to ~250 m; cattle tag batteries drain in under a day — UX failure.
• LoRa Gateway option: Signal range up to 20 km with ~1-year tag battery life — practical for large-scale ranch operations.

Benchmarking against the Western US livestock industry, I quantified the actual device count needed per ranch to validate the product positioning.

• Ranch size reference: Per USDA data, small US family ranches average 231 acres; a common rule-of-thumb is at least 1 acre of pasture per cow.
• Coverage calculation: A single Solar Point's LoRa antenna effective area reaches 314,000,000 mm² (10 km radius circle), far exceeding the 934,822 mm² needed for a small ranch.
• Result: On average, one Solar Point fully covers an entire small family ranch.

Energy autonomy is the core of an off-grid system. Based on average sunlight conditions in the Western US, I calculated the balance between solar charging and system consumption to derive theoretical battery life.

• Sunlight assumption: Day 1 — 9 hrs working + charging → Night — 15 hrs working only → Day 2 — 9 hrs of recharge.
• Life formula: (Solar input power − System power) × Charge time ÷ System power = Battery life.
• Result: (10W − 2.17W) × 9 hrs ÷ 2.17W ≥ 30 hrs — theoretically endures ~30 hours of continuous no-sunlight operation, roughly a full day of autonomy.

From structural design to battery selection, every decision revolves around the core requirement of single-person installability.

• Panel dimensions: 625 × 625 mm photovoltaic panel, just 25 mm thick with a 65 mm main body — balancing collection efficiency and transport volume.
• Battery choice: 18650 Li-ion pack (1.5 kg) vs lead-acid (8.6 kg). Chose 18650 — nearly a 6× weight reduction, making single-person transport to remote sites feasible.

The single-person install promise breaks down into three concrete steps — paired with quick-drying cement, the entire deployment can be completed on-site in one visit.

• Step 01. Dig the ground hole and pour quick-drying cement — cures in 20-40 minutes.
• Step 02. Pole up the battery pack and screw it onto the base.
• Step 03. Rotate the panel plate onto the battery pack — no tools required, no second person needed.
