Home Upgrade Specialist vs Vivint Solar (now Sunrun)
Sunrun acquired Vivint Solar in 2020. All new installs are now Sunrun-branded. Here’s the honest 2026 LA comparison — including what to do with an existing Vivint PPA. Note: the federal residential solar tax credit applied to systems placed in service through December 31, 2025; the 30% references below reflect that period. Confirm current eligibility with a tax professional — Home Upgrade Specialist is not a tax advisor.
Quick verdict for LA homeowners.
Vivint Solar (now Sunrun): National installer with a heavy PPA / lease model. Strong if you specifically want zero-upfront-cost solar with a 20-25 year contract and don’t want to claim the federal tax credit yourself. Weak on combined service — solar-only focus.
Home Upgrade Specialist: Ownership-only solar with 0% financing options that match PPA monthly cash flow. With ownership you keep any available federal tax credit and state/utility rebates (subject to current law), versus a PPA where the provider claims them. Combined HVAC + Powerwall + roofing + EV charger under one contract.
For most LA homeowners, ownership-with-financing delivers a stronger lifetime ROI than a PPA (actual results vary by contract, rates, usage, and financing).

| NEM 3.0 sizing | Standard PPA sizing | Battery-paired for max self-consumption |

| NET LIFETIME COST | $60,800 | $19,500 |
Illustrative estimates only; actual costs and savings vary by system, usage, rate plan, financing, and eligibility. Assumes a 7kW system at $21,000 gross cost in LA. Sunrun PPA uses a typical 2.9% annual escalator. HUS uses 0% APR financing through GreenSky or GoodLeap (qualifying credit). Home Upgrade Specialist is not a tax advisor.
Got an existing Vivint Solar PPA?
Many LA homeowners signed Vivint Solar PPAs between 2014–2020 that now transfer to Sunrun. If you have one, three options exist:
- 1Buy out the contract — Most Vivint/Sunrun PPAs include year-6, year-10, or year-15 buyout windows. Buyout costs typically run 60-80% of remaining contract value. HUS provides buyout cost analysis as part of a free consultation.
- 2Add solar capacity in parallel — HUS can install additional solar panels on a separate ownership system (your buyout option keeps the original PPA running but you own all new capacity going forward). Common for homes that added EVs or heat pumps after the original install.
- 3Add battery + heat pump separately — If you’re happy with the existing solar PPA, HUS can add Tesla Powerwall, heat pump HVAC, and EV charger under separate ownership contracts. A federal tax credit may apply to a battery depending on current law and eligibility — confirm with your tax professional.
