Hilltop net-zero Retreat.

Hilltop Retreat is a quiet off-grid cabin set into rolling hills — designed to live lightly on the land while staying fully powered year-round. The owners wanted energy independence without a visible industrial footprint or noisy generators.

We delivered an 8.2 kW rooftop array paired with high-capacity battery storage, sized for winter autonomy and peak summer loads. Every component was chosen for durability, quiet operation, and a clean visual profile that respects the architecture.

Beyond day-one performance, the system was engineered for long-term reliability — from modular racking that protects the roof membrane to monitoring that flags issues before they become outages. The result is a retreat that runs itself, season after season.

Deliver full off-grid autonomy without scarring the landscape

The site had no utility connection and limited access for heavy equipment. Key challenges included:

• Steep terrain and a narrow access road restricted equipment delivery
• Winter cloud cover required oversized storage for multi-day autonomy
• Strict aesthetic guidelines — no ground mounts or visible conduit runs

Engineered for autonomy, designed to disappear

To address these challenges, we implemented:

• Flush-mounted 8.2 kW array aligned to the roof pitch for a seamless silhouette
• 20 kWh lithium battery bank with intelligent load prioritization
• Concealed conduit routing and remote monitoring for hands-off ownership
