Solar Panels in East Hartford, Connecticut

Eversource is the electric distribution company serving East Hartford.

Connecticut's Residential Renewable Energy Solutions program is administered by Eversource and United Illuminating within their respective service territories. PURA describes RRES as the program that replaced legacy net metering for new enrollment beginning in 2022.

Under **Buy-All**, all electricity produced by the system is exported to the grid. Generation and household consumption are measured separately, and Eversource compensates the enrolled beneficiary under the applicable PURA-approved tariff. The household continues purchasing the electricity it consumes from Eversource.

Under **Netting**, the home uses solar production first and exports production that is not consumed onsite. Eversource calculates a bill or credit from net usage and production at the end of the billing cycle, and unused credits roll forward under the tariff rules.

For projects applying in 2026, Eversource also publishes a Solar Energy Adjustment applicable to total production under the Netting tariff. Current details appear in Eversource's RRES guidance.

Ask each installer to show:

• Which RRES election the proposal assumes.
• The program year used in the calculation.
• Every current tariff rate, adjustment, and fee included.
• The amount of electricity assumed to be consumed onsite or exported.
• Whether the proposed ownership agreement controls who receives tariff compensation.

Current tariff terms should be checked directly with Eversource and PURA before signing.

East Hartford issues eligible solar permits instantly. The Town's April 2025 SolarAPP+ update says that once SolarAPP+ approves a project, the contractor submits the approval document and approval ID through the Town's OpenGov/ViewPermit system, pays the required fee, and instantly receives the permit.

Instant issuance applies only to projects meeting the SolarAPP+ rules. Eligible work is new rooftop solar photovoltaic on detached one- and two-family dwellings, townhomes, and related accessory structures such as a garage or accessory dwelling unit. A qualifying application may include related energy storage and a service-panel upgrade, and the system must be 38.4 kW or smaller.

The Town states the exclusions directly: "Properties in the Historic District, in FEMA Flood Zones or projects which include structural reinforcements are NOT eligible." A homeowner in East Hartford's historic district therefore loses the instant-permit path and falls back to standard Town review. The same is true for a flood-zone property or a design that depends on structural reinforcement.

East Hartford maintains two application tracks. The **Solar - Residential 1&2 Family (and SolarAPP+)** application covers one- and two-family residential projects, including SolarAPP+ submissions. The **Solar - 3+ Family Residential and Commercial** application covers residential buildings with three or more units and commercial projects. A multifamily owner should use the track matching the building rather than treating an individual dwelling unit as a detached-home application.

The instant-permit sequence for an eligible project is:

1. The contractor registers with SolarAPP+, completes its certification, and supplies the contractor-license information required for the jurisdiction.
2. The contractor submits the design to SolarAPP+ for automated plan review and obtains an approval document and approval ID.
3. The contractor creates or uses an East Hartford ViewPermit account and selects Solar - Residential 1&2 Family (and SolarAPP+).
4. The contractor uploads the SolarAPP+ approval, submits the Town application, and pays the required permit fee; the Town then issues the eligible permit instantly.
5. After installation, the contractor schedules the municipal inspection by calling the Permits and Inspections Division at (860) 291-7340.
6. The installer separately completes Eversource interconnection and RRES enrollment before the system is authorized to operate.

Instant permitting is not a waiver of inspection. East Hartford says the inspection verifies installation practices, workmanship, and adherence to the approved design. The homeowner should keep the issued permit, approved design, change orders, inspection result, and Eversource records together so the installed project can be compared with what the automated review approved.

The SolarAPP+ limit and the Connecticut statutory threshold perform different jobs. SolarAPP+ permits eligible systems up to 38.4 kW to use East Hartford's automated path. Under CGS §16-245nn(a)(1), the 30-day municipal decision requirement applies only to a system of 12 kW or less, installed on the roof of a single-family home, and conforming to the Connecticut State Building Code.

A 20 kW system illustrates the difference. It is above the statute's 12 kW definition and therefore has no 30-day decision deadline under §16-245nn. It is still below the 38.4 kW SolarAPP+ cap and can receive East Hartford's instant permit if it satisfies the program's building-type, roof, flood-zone, historic-district, structural, and other eligibility rules.

Change orders have their own sequence. The contractor submits the revised project to SolarAPP+ for a new approval ID and resubmits it through ViewPermit. East Hartford does not charge for amended plans, and the Town says SolarAPP+ allows three changes without charge. A contract should state who prepares a change, whether a fourth or later change creates a SolarAPP+ cost, and whether a changed layout triggers an updated production estimate.

The Town's online-permitting page publishes residential fees of $30 for the first $1,000 of estimated cost and $15 for each additional $1,000. Those residential figures should not be confused with the separate commercial and Fire Marshal schedules on the same page. Ask the contractor which project valuation and application track it will use and whether the fee is included in the proposal.

East Hartford's adopted 2025–2035 Plan of Conservation and Development describes a varied housing inventory with a greater share of multifamily housing than many comparable communities. It reports that nearly 70 percent of the Town's single-family housing was built between 1940 and 1980.

The Town's housing-planning materials also report a tenure split of approximately 58.5 percent owner-occupied and 41.5 percent renter-occupied housing. That split matters for rooftop solar because a renter cannot authorize work on a roof, and an owner in a shared building needs to establish which roof area, electrical service, meter, and account the proposed system will serve.

The large 1940–1980 single-family cohort makes East Hartford different from a town dominated by recent construction or much earlier prewar homes. A mid-century building may have had multiple roof replacements, additions, service changes, or panel upgrades since it was built. The useful comparison is the present documented condition, not the construction year alone.

For a detached or two-family home, ask for the roof covering and installation date, sheathing and framing observations, prior additions, electrical-service rating, panel capacity, grounding, meter location, and every upgrade included in the scope. SolarAPP+ can include a service-panel upgrade, but that eligibility does not establish whether a particular home needs one or whether its cost is included.

Structural reinforcement changes the permit path. If an installer concludes that reinforcement is required, the project is not eligible for SolarAPP+ even when the array is below 38.4 kW and the building is otherwise eligible. The proposal should identify the structural finding, the proposed work, the professional responsible for the design, and the standard Town review that replaces instant issuance.

Building type changes the application path as well. Detached one- and two-family dwellings, townhomes, garages, and accessory dwelling units can fall within SolarAPP+ when the other rules are satisfied. Residential buildings with three or more units use the separate 3+ Family Residential and Commercial application. An owner should not rely on the automated route until the contractor has classified the building and scope correctly.

Historic designation has a direct scheduling consequence in East Hartford. The local Historic District Commission accepts Certificate of Appropriateness applications and supporting documents electronically. The Commission is organized under Connecticut's local historic-district statutes, while the Town's planning map also identifies separate National and State historic resources.

Those designations should not be treated as interchangeable. East Hartford's historic-resources map distinguishes the local historic district from National Register districts and individual landmarks. A homeowner should confirm the applicable boundary and jurisdiction for the property rather than infer the review process from a historic name in a listing.

For a property in the Town's Historic District, the immediate practical result is clear: SolarAPP+ is unavailable. The contractor must use standard review and should identify any Certificate of Appropriateness materials, exterior views, equipment locations, and Commission timing needed before the homeowner relies on a construction date.

A FEMA Flood Zone creates the same loss of automated eligibility for a different reason. The Town's property and GIS resources link residents to parcel information and FEMA mapping. The contractor should document whether the exclusion applies and identify the standard application materials required for that site.

Before comparing East Hartford proposals, confirm:

• The building type and the Town application track selected for it.
• Who owns and controls the roof and which Eversource account the system will serve.
• The roof covering, installation date, condition, and estimated remaining service life.
• Roof framing, sheathing, prior additions, and whether reinforcement is required.
• Whether the project is at or below the 38.4 kW SolarAPP+ cap.
• Whether the parcel lies in the Historic District or a FEMA Flood Zone.
• Electrical-service, meter, panel, grounding, disconnect, and storage work included in the proposal.
• Which design will be submitted to SolarAPP+ or standard Town review.
• Who schedules the inspection and closes out correction items.
• Whether a changed design will require a new approval ID and production model.

For a reproducible production reference, a PVWatts V8 model was run near central East Hartford using:

• 1 kW DC capacity.
• Standard modules.
• Fixed roof mounting.
• 30-degree tilt.
• 180-degree azimuth.
• 14 percent system losses.
• Latitude 41.7637 and longitude −72.6851.
• No additional property-specific shading input.

Those inputs produce approximately 1,289 kWh of first-year AC electricity per 1 kW of DC capacity. The model can be reproduced using the PVWatts V8 documentation.

This East Hartford result is an orientation-controlled comparison baseline, not a production promise. It does not represent the actual roof planes, shade, snow conditions, equipment, electrical limits, flood-zone conditions, or historic review affecting a particular property.

The production model used in a proposal should match the design submitted for approval. If SolarAPP+ issues an approval ID for one layout and a change order later alters panel count, roof plane, tilt, equipment, or losses, the contractor should provide an updated model tied to the new approval ID.

A project moving from SolarAPP+ to standard review because of structural reinforcement, historic jurisdiction, or flood-zone status may also acquire new design and cost assumptions. The homeowner should compare the final approved design rather than the preliminary automated-eligibility estimate.
