Tesla Solar Panels + Powerwall Installation Experience
Tesla installer credential used for Powerwall, solar panel and Wall Connector planning. HUS no longer installs new Tesla Solar Roof systems. Homeowners should verify current installer status through Tesla.com/findaninstaller.
Enphase Battery and Inverter Planning
Enphase IQ microinverter and IQ Battery projects should be reviewed around equipment compatibility, utility rules and current installer documentation.
Insurance Documentation
Insurance and workers' compensation documentation should be confirmed in writing when required for the project.
How we review home energy projects.
Home Upgrade Specialist reviews HVAC, solar, battery, roofing and EV charger projects with written scopes, permit planning, utility steps and warranty documentation.
| Trade | Planning focus | Common review items |
|---|---|---|
| HVAC system installations (AC, furnace, heat pump) | Load review, equipment selection | Permit and rebate documentation where applicable |
| Solar panel installations | Utility bill and roof review | NEM, interconnection and battery pairing where applicable |
| Tesla Powerwall + Enphase battery planning | Backup-load and utility review | Powerwall, Enphase and SGIP documentation where applicable |
| Roof replacements | Roof condition and material review | Solar-ready roof timing where applicable |
| EV charger installations | Panel capacity and load review | Charger location, conduit route and utility program review |
| Combined home energy projects | One coordinated written scope | Permits, inspections and warranty documentation reviewed |
Project scope, availability, trade responsibilities, warranty terms and permit steps should be confirmed in the written estimate before work begins.
Install PhilosophyHow we actually do the work.
1. Coordinated licensed trade teams
Combined HVAC, solar, battery, roofing and EV charger projects can involve multiple trade disciplines. Home Upgrade Specialist coordinates project management, permit steps, inspection timing, written scope responsibilities and warranty documentation.
Why this matters: clear responsibility helps avoid finger-pointing between roofing, solar, battery, electrical and HVAC work, especially when one project includes multiple trades.
2. We review incentive eligibility and documentation.
Incentive rules, funding, utility requirements and tax treatment can change. Home Upgrade Specialist reviews available program documents during project planning before any savings estimate is discussed. See our LA energy rebates stacking guide for planning context.
3. We size systems around the home and project goals
HVAC equipment should be selected around load, duct condition, airflow, comfort goals and permit requirements. When needed, load calculations help avoid equipment that is too small or too large for the home.
Solar planning should also be based on usage history, roof condition, utility territory, NEM rules, battery goals and future loads such as EV charging or heat pumps. Oversizing assumptions should be reviewed before a system is proposed.
4. Coordinated project management and written scope
For combined-trade projects such as heat pump, solar, battery, roofing and EV charger work, Home Upgrade Specialist helps coordinate scheduling, communication, permit steps, inspections and warranty documentation. Warranty terms should be confirmed in the written agreement.
5. Permit and inspection planning
Permit and inspection requirements vary by city, utility territory and project scope. The written estimate should explain who pulls the permit, who schedules inspection, what utility documentation is included and what fees or exclusions may apply.
6. Honest comparisons against competitors
We publish honest side-by-side comparisons against our competitors — including when other companies are the better fit. See our comparison pages for Solar Optimum, Sunrun, Tesla Energy, SunPower, Brody Pennell, JW Heating & Air, and 9 other LA-area contractors. We tell you when they're the right fit.
