From one utility bill to an operating NOI strategy.
We test whether energy can strengthen the property case before anyone sells the owner equipment. Every stage produces a written output, identifies the next risk, and can stop a project that does not hold.
Analyze a utility bill
Run stage 01 and 02 on your own site, right now.
Attach a recent utility bill and we read the determinants off it, or enter them yourself. The output is a modeled system fit and gross bill savings — not a quote, not owner NOI, not an operating result.
Example property — edit any field to model your own
Large uninterrupted roof, steady daytime load — usually the strongest solar-plus-storage fit.
Strong candidate for solar plus storage
A meaningful demand component and enough billed peak for storage to work against.

These are gross reductions to your current utility charges. They are not owner NOI: financing, operations, insurance and program fees all sit between the two.
Performance payments settle on measured dispatch during declared events, not on nameplate capacity. Event duration, availability and delivered kW decide the receipt, so no dollar figure is modeled here. See the program manual, §6.5–6.6.
Connecticut — Eversource & United Illuminating territory. We reply with a written read of your tariff.
We send this exact modeled result as a one-page summary, plus the assumptions behind it. No follow-up unless you ask for it.
Assumptions behind these numbers
- Production is modeled at 1200 kWh per kW-DC per year for this state, before shading and tilt losses.
- Array size is the lesser of usable area (525 kW at 80 sq ft per kW after setbacks) and your own consumption (1,200 kW).
- 85% of production is assumed self-consumed at the energy-only rate; export compensation is not modeled.
- Savings shown are gross reductions to your current utility charges, not owner NOI.
- Performance-program receipts are not modeled as dollars: Connecticut's Energy Storage Solutions payments settle on measured dispatch during declared events, not on nameplate capacity (Program Manual revised 2026-05-19, §§6.5–6.6).
- Storage is sized to 35% of billed peak for this site type at a 2-hour duration, and modeled to clear the monthly peak in 10 of 12 months.
- Federal, state and utility incentives depend on project facts and applicable requirements. NOI does not provide tax advice.
- Nothing here is a quote, a guarantee or an operating result. Real numbers require interval data, a site visit and underwriting.
- 01
Read the property's energy cost structure
- What NOI does
- We read the actual bill: rate schedule, demand determinants, time-of-use periods, riders and any program charges already applied. We identify which cost components are addressable and which are not.
- What you provide
- One recent utility bill per meter, and interval data if the utility provides it.
- What can delay or disqualify
- A tariff without a demand component, very flat load, or a bill that reflects a shared or master-metered arrangement can rule a site out at this stage.
- What this stage produces
- A written read of your tariff and cost structure, and a go/no-go on deeper analysis.
- 02
Validate the asset and site constraints
- What NOI does
- We validate the physical and electrical facts: roof or ground area, structure, roof age and condition, switchgear and service capacity, available space for equipment, and site access.
- What you provide
- Site access, roof and electrical documentation where available, and confirmation of who controls the premises.
- What can delay or disqualify
- Roof condition or remaining life, insufficient service capacity, restricted equipment siting, lease terms, or a hold period too short to support the asset.
- What this stage produces
- A validated site record with the constraints that shape system design.
- 03
Build and underwrite the NOI case
- What NOI does
- We size solar and/or storage against the measured load profile and tariff, model the operating case, and take the project through financing underwriting. Contract terms are set here, in writing.
- What you provide
- Entity and ownership information for underwriting, and decisions on scope and objectives.
- What can delay or disqualify
- Underwriting outcome, credit and entity structure, eligibility for any program relied on in the case, and equipment availability.
- What this stage produces
- A system design, an operating case with stated assumptions, and an executable agreement.
- 04
Structure capital and coordinate delivery
- What NOI does
- We coordinate engineering, permitting, the installation partner, equipment procurement, utility interconnection and commissioning, and hold accountability for the schedule.
- What you provide
- Signature authority for utility and jurisdictional filings, and site coordination during construction.
- What can delay or disqualify
- Authority-having-jurisdiction review, utility study and interconnection queues, equipment lead times, structural remediation and weather.
- What this stage produces
- A commissioned, interconnected system with as-built documentation.
- 05
Operate, measure and protect the case
- What NOI does
- We monitor performance, dispatch storage against your tariff, coordinate maintenance and warranty claims, and handle enrollment and compliance filings for any program the site participates in.
- What you provide
- Continued site access for service, and notice of changes in occupancy, load or ownership.
- What can delay or disqualify
- Program rule changes, tariff changes, load changes, and site conditions that affect access or performance.
- What this stage produces
- Periodic performance and program reporting for the operating life of the system.
We do not publish a single installation duration. Permitting, engineering, equipment lead times, interconnection, utility review and site conditions determine the schedule, and we give you a project-specific range once stages 01 and 02 are complete.

Energy performance translated into the property operating case.
NOI brings metered energy, utility cost, peak-demand performance, eligible program payments and operating status into one reporting view. Financial treatment remains property-, lease-, accounting- and agreement-specific.

Three ways a project gets paid for.
Owner-funded
You pay for the system and keep the savings and any eligible credits, subject to your tax position.
Financed
The project is funded with debt or a lease arranged for the property, repaid from project cash flow.
Third-party funded
A funding partner pays for and owns the equipment; you host it under an agreement and buy energy or receive a payment.
Projects are delivered owner-funded, financed, or third-party funded. Which structure applies — and who pays, owns the equipment and receives the benefit — is set in the project agreement after underwriting.
The responsibility split, in plain language.
The exact allocation for your project is set in your agreement. This is the standard structure we work from.
| Item | Standard treatment |
|---|---|
| Capital | Financing is arranged by NOI for qualifying projects, subject to underwriting and eligibility. Where a project is customer-funded, capital sits with the customer. |
| Engineering | NOI coordinates licensed engineering through its delivery network. |
| Equipment | Specified by NOI from its qualified catalog and procured through the delivery partner or manufacturer. |
| Installer management | NOI selects and manages the installation partner. The licensed installer of record is the delivery partner. |
| Interconnection | NOI prepares and manages utility applications; customer signature authority is required. |
| Utility / program enrollment | NOI prepares and files enrollment and compliance documentation where the site is eligible. |
| Monitoring | NOI monitors system performance and storage dispatch. |
| Maintenance | Coordinated by NOI and performed by the service partner. |
| Insurance | Property insurance stays with the owner; contractor and equipment coverage is carried by the delivering parties. Exact allocation is set in the agreement. |
| Warranty | Manufacturer warranties are held for the equipment; NOI administers claims. |
| Reporting | NOI issues performance and program reporting on the cadence set in the agreement. |
| End of term | Options are defined in the agreement for the specific project. There is no single universal term applied to every project. |
Federal, state and utility incentive availability depends on project facts and applicable requirements. NOI does not provide tax advice; evaluate any credit with your tax counsel.
