Legacy Vivint Solar Agreements and Sunrun

Sunrun acquired Vivint Solar in October 2020, and Vivint Solar remains a Sunrun subsidiary. This guide explains how Los Angeles homeowners can review a legacy Vivint lease or PPA, request current contract figures, evaluate home-sale or upgrade plans, and compare any new owner-purchase proposal.

TL;DR

Quick verdict for LA homeowners.

Legacy Vivint agreement: The controlling document is the signed lease, PPA or purchase agreement now administered through Sunrun. Review the current payment schedule, escalator or rate terms, transfer requirements, maintenance responsibility, buyout or prepayment language and system condition.

New HUS proposal: HUS can prepare a separate owner-purchase or multi-trade scope for solar, battery, roofing, HVAC or EV work. Compatibility, permission, utility requirements and interaction with the existing Sunrun agreement must be reviewed before any modification.

Comparison takeaway: Do not compare a generic PPA against a generic ownership example. Compare the actual remaining contract obligations against an itemized new proposal, including roof, electrical, financing, service and utility costs.

Contract comparison

How to compare a legacy agreement with a new proposal.

Use the actual Sunrun account documents and the complete new proposal. A generic 25-year example cannot substitute for the customer's payment history, remaining term, utility usage, roof condition or financing terms.

Ask Sunrun for current account figures and contract options. Review legal questions with an attorney and tax questions with a qualified tax professional. HUS can prepare a separate itemized project proposal but should not interpret or promise the legal effect of the legacy agreement.

What to do with an existing Vivint Solar agreement.

Start with the signed agreement and current Sunrun account information. Do not assume that every legacy contract has the same purchase, prepayment, transfer or modification terms.

  • 1Request current figures from Sunrun: ask for the remaining term, payment or rate schedule, transfer process, purchase or prepayment options, and any requirements for roof or electrical work.
  • 2Document the existing system: collect equipment labels, monitoring access, production history, permits, utility approval, service history and roof condition.
  • 3Review proposed modifications before signing: additional solar, battery, roofing, HVAC or EV work may require contract consent, technical compatibility, utility review and permits.
  • 4Compare an itemized new proposal: separate the new equipment and construction scope from the existing contract obligations so the homeowner can evaluate both clearly.
  • 5Use qualified advisors: review contract interpretation with an attorney and tax or financing questions with the appropriate professional.
Documents to gather

Prepare for a legacy Vivint and Sunrun contract review.

  • ✓Original Vivint Solar agreement, amendments, assignment notices and current Sunrun account documents.
  • ✓Current payment or rate schedule, remaining term, transfer instructions and any purchase or prepayment quote.
  • ✓Utility bills, production history, monitoring access, permits and permission to operate documents.
  • ✓Solar equipment labels, roof condition, electrical panel photos and service or repair records.
  • ✓Written requirements for roofing, battery storage, added solar, home sale or system modification.

Use these records to compare the actual remaining contract obligations against a complete new project proposal.

FAQ

PPA-to-ownership FAQ.

What happened to Vivint Solar?
Sunrun completed its acquisition of Vivint Solar in October 2020, and Vivint Solar became a wholly owned Sunrun subsidiary. Legacy customers should follow the current Sunrun account, service, transfer and contract channels shown in their documents.
Should I buy out or change my legacy Vivint agreement?
That depends on the signed agreement, current Sunrun figures, remaining payments, transfer or purchase terms, utility account, system condition and home plans. HUS can prepare a separate project proposal, but contract interpretation should be reviewed with Sunrun and a qualified attorney.
Is ownership cheaper than a Sunrun PPA or lease?
Not in every case. Compare the actual remaining contract obligations, utility charges, maintenance responsibilities, buyout or prepayment amount and any new-system price, financing, roof work and electrical work. Avoid using a generic savings table.
Can a battery be added to my existing Vivint Solar system?
Possibly, but compatibility and permission must be reviewed first. The installer should inspect the inverter, modules, electrical configuration, permits, monitoring and interconnection, and confirm any required approvals from Sunrun, the utility and the permitting authority before committing to the work.
