Tesla Solar + Powerwall Battery Backup
Challenge
After a severe hailstorm, the homeowner’s roof took major damage. What should have been a straightforward insurance claim turned into a six-month grind: delayed adjuster visits, incomplete coverage estimates, and repeat inspections. When Phoenix Exteriors performed a deeper evaluation, we found a bigger problem—moisture intrusion had led to mold growth on sections of the roof decking. Simply swapping shingles (as the original claim suggested) would have sealed in the problem and risked ongoing indoor air-quality issues. The homeowner also wanted to use this forced replacement as an opportunity to transition the home toward energy independence with a Tesla solar system and battery backup—but that required starting with a clean, structurally sound roof deck.
Solution
Phoenix Exteriors took over claim advocacy, documenting hidden damage and the mold-compromised decking so the full scope could be recognized. Once approved, we fully re-decked the home—removing all compromised plywood and installing fresh, properly ventilated decking to create a healthy substrate for long-term performance.
With the structure secured, our clean-roof platform allowed for a seamless Tesla solar installation. We paired high-efficiency Tesla Solar Panels with a Tesla Inverter and two Tesla Powerwall batteries for on-site energy storage. This configuration lets the homeowner store solar generation for use at night, during peak utility rates, or during outages—unlocking both savings and resilience.
Results
The completed project delivered on every goal: the Tesla solar array now produces enough power to offset the home’s entire annual electricity usage, leaving only the small utility connection fee on each bill. Because Phoenix Exteriors removed and replaced every mold‑compromised sheet of plywood, the roof deck is now structurally sound and code‑compliant, eliminating long‑term health and moisture concerns. Our thorough documentation persuaded the insurer to cover the full scope of work—including the redecking—so the homeowner paid only their deductible while gaining a brand‑new, future‑proof energy system. Most importantly, the client finally has peace of mind: a healthy roof, reliable backup power during outages, and energy savings that will compound for decades.
Impact
In its first year, the system is projected to generate ~16,130 kWh of clean electricity, dramatically reducing grid dependence and carbon footprint while providing stored backup power for storms and outages common in hail-prone regions. The combination of a healthy roof deck and long-life solar system positions the home for decades of performance—and keeps long-term energy savings compounding year after year.
