In this Solar Conversation, Kerim Baran speaks with Cole Ashman, Founder and CEO of Pila Energy, about their mission to make battery storage simple, scalable, and accessible to homeowners, renters, and small businesses alike. Drawing on his experience at Tesla and Span, Cole shares how Pila’s distributed, plug-and-play battery system delivers resilience, optimizes energy use year-round, and bypasses many of the barriers that have slowed storage adoption.
1. From Tesla & Span to Pila Energy (00:00)
Cole shares his personal journey from growing up in hurricane-prone New Orleans to working at Tesla on Powerwall and at Span on smart panels. These experiences shaped his vision for Pila—a company focused on delivering energy resilience and intelligence in a more accessible form.
2. Identifying the Gap in Energy Storage (04:03)
While Tesla and Span offer great solutions, Cole saw a gap in accessibility—particularly for renters, small businesses, and those without the ability to install large fixed systems. Pila was founded to fill that gap with a solution that can be deployed quickly and without permits.
3. The Pila Product: Distributed, Plug-and-Play Batteries (05:15)
Pila’s first product is a 1.6 kWh, 2.4 kW slim battery designed to power essential appliances like refrigerators, AC units, and sump pumps. Instead of one large unit in a garage, users can place smaller units throughout the home, starting with one and scaling up over time.
4. Smart Sensors and the “Digital Twin” Approach (07:01)
Pila integrates fridge temperature sensors to ensure food safety during outages, not just to confirm power is on. This small, wireless “air-tag-like” sensor works with any fridge, creating a more meaningful and actionable energy monitoring experience.
5. Mesh Communication & Nano-Grids (10:22)
Instead of relying on Wi-Fi, Pila batteries use a proprietary mesh system to communicate and manage priorities across the home. Each unit includes a built-in grid disconnect, creating independent nano-grids in each room during outages.
6. Beyond Backup: Year-Round Energy Optimization (13:32)
While resilience is the entry point for most customers, Pila’s software also enables time-of-use optimization, solar charging, and participation in demand response programs. This turns the system into a tool for both savings and security.
7. Go-to-Market & Partnerships (15:22)
Pila will begin shipping later this year with direct sales through its website and partnerships with solar installers, utilities, and other energy providers. The product complements, rather than replaces, existing storage solutions like Powerwall and generators.
8. Pricing & Competitive Positioning (19:07)
At $1,299 for a 1.6 kWh unit, Pila comes in around 30% cheaper per installed kWh than many whole-home battery systems. The plug-and-play design removes the need for interconnection permits, significantly reducing cost and installation time.
9. Manufacturing & Scalability (21:53)
Pila’s modular design and use of industry-standard components allow flexible manufacturing, with plans to expand U.S.-based production over time. The focus remains on safety, quality, and ensuring a 10-year cycle life for each battery.
10. The Vision Ahead (23:18)
Pila aims to scale its distributed battery nodes from homes to large commercial and multi-tenant buildings, with hundreds of units working as a unified system. Cole invites contractors, partners, and customers to connect as the company prepares for large-scale deployment.
