SolSource is the Developer and Third-Party Owner (TPO) of the energy system under the Propel program. As the ESA provider, SolSource finances, owns, and manages the system during the initial term of the agreement.

An ESA is an agreement between the customer and the system owner under which the latter agrees to provide energy services. ESAs, Leases, and Power Purchase Agreements (PPAs) are all types of Third Party Ownership (TPO). With TPO products, the system is owned by the TPO provider, not the customer

SolSource owns the system initially, maximizing the value of the available tax incentives, resulting in a lower total system cost for the customer. The homeowner then finances that lower cost with a Concert loan, making their solar system more accessible without a large cash outlay.

Probably not. Propel is specifically designed to provide homeowners with a low-cost path to ownership by year 5. While the agreement does allow homeowners to opt out of the Early Buyout, the greatest financial benefit comes from exercising the buyout option and becoming the system owner. If a homeowner is not interested in owning the system, other third-party ownership models, such as traditional leases and PPAs, may be more appropriate.

When the homeowner signs the Propel ESA, they agree to prepay for 25 years of energy services and fund the Early Buyout Fee, both of which are financed through a Concert loan. These funds are held by the lender and automatically applied to purchase the system at the end of year 5, unless the homeowner elects to opt out. If the homeowner does elect to opt out, they’ll still have the option to purchase the system at the end of years 6.5 or 8.

At the end of year 25 (the initial term), the homeowner may do one of the following: 

● They can purchase the system at Fair Market Value (FMV). 

● They can renew their agreement for up to 10 additional one-year renewal terms. 

● They can have the system removed at their expense.

● Before the end of year 5 

○ Loan: Must be transferred to a new qualified borrower or paid off 

○ ESA: 

■ Can be transferred to the new homeowner. If transferred, the buyer must assume the Early Buyout Option. 

■ Alternatively, the seller may choose to purchase the system before the sale and include it in the home transaction, though this is typically less advantageous than transferring the ESA. 

● After the end of year 5 

○ Loan: Must be transferred to a new qualified borrower or paid off 

○ ESA: If the Early Buyout has not been exercised then the new homeowner must purchase the system. The homeowner cannot transfer the ESA after year 5.

● Modules, inverters, racking, balance of system (BOS) 

● Energy storage system components (batteries) 

● Required electrical upgrades such as main panel upgrades, line-side taps, subpanels 

● Tree trimming costs that will improve the solar system production 

● Structural reinforcement to support the solar 

● Other items needed to support an effective solar installation

Roofing types must be rolled comp/asphalt shingles, fiber cement, metal shingles, standing seam, clay or concrete tiles, rolled tar, and gravel are approved roofing materials.

There are 3 Reamortization Dates after the 12th, 24th and 36th monthly payment.

The customer’s first loan payment is due ~75 days after Substantial Completion. If the project has not achieved PTO within 60 days of Substantial Completion, the customer’s first payment will be deducted from the 10% PTO Holdback payment owed to the installer. If the project continues to not achieve PTO, subsequent payments will be deducted from the PTO Holdback and applied to the customers loan.

The ESA includes a 5-year Performance Guarantee. A production assessment is conducted at the end of years 2, 4 and 5. If the system underperforms against the guarantee, the homeowner will receive a refund based on the shortfall in kilowatt-hour (kWh) production, multiplied by the guaranteed price per kWh. Excess production in earlier periods can be carried forward to offset future shortfalls.

The system is designed using high-quality components from reputable manufacturers that offer warranties aligned with the full term of the ESA: 25 years for the solar system and 15 years for the battery. If a major component fails during the first 5 years, the system owner will repair or replace it at no cost to the homeowner under the Limited Warranty. 

After Year 5, if the homeowner has exercised the Early Buyout and owns the system, SolSource will continue to provide asset management services, including monitoring and warranty claim coordination, until the end of year 25. If the homeowner has opted out of the Early Buyout and SolSource retains ownership, SolSouce will provide monitoring and claims management services through the end of year 25.

All systems installed under Propel use Enphase microinverters, which provide module-level monitoring through the Enphase Enlighten platform. Homeowners will have access to real-time and historical performance data via the Enphase app, allowing them to track system production, energy usage, and battery status (if applicable). 

To ensure accurate monitoring and performance reporting, homeowners must maintain a functioning indoor high-speed internet connection to support the system’s communication gateway. If internet access is unavailable or interrupted, the system owner may not be able to monitor the system remotely, and the homeowner may be required to manually provide production data from the system.

Under the Propel program, SolSource is responsible for the system during the first 5 years, unless damage is caused by homeowner negligence. Beginning in Year 6, the responsibility to insure the system shifts to the homeowner, regardless of whether they choose to purchase the system or continue under the ESA.
