1. Project Overview

1.1. Introduction

Oak Park Elementary School District 97 (hereby referred to as “the District”) is soliciting

proposals (“Proposals”) from qualified solar photovoltaic (PV) providers (“Proposers”) for turn-

key installation of a rooftop solar PV project at the site addresses below pursuant to Section

19b of the Illinois School Code (105 ILCS 5/19b-1 et. seq.). Proposers shall have

demonstrated experience in designing, planning, scheduling, permitting and constructing

complete solar PV systems, have knowledge of local utilities, provide project financial analysis,

and support the District in securing rebates and other financial incentives available for the

project. Proposals will be evaluated based on the relative merits of the Proposer’s response as

documented in Section 5, Proposal Evaluation.

1.2. District Authorized Representative

The District has retained Nania Energy Advisors (“Representative”) as its representative in

regard to solicitations for distributed generation at the determined sites and has authorized

Representative to oversee the RFP process, evaluate proposals, and make recommendations

to the District. All questions and other correspondence for this RFP shall be submitted via email

to solarRFP@naniaenergy.com with the subject line “Oak Park ESD 97 Solar RFP.” All

requests from Representative in regards to this solicitation should be regarded as if they are

requests from District.

Firms, including all agents or subcontractors, who contact any other District personnel, either

verbally or in writing, concerning this RFP, are in violation of the procurement procedures and

any submitted proposals from or including such individuals or entities may be disqualified.

In accordance with 105 ILCS 5/19b-5, the District discloses that no energy services contractor

has participated in the preparation of the specifications of this solicitation.

• Desired Solar PV System Description: The District is seeking rooftop PV systems at the

above locations. The above listed solar PV details are preliminary in nature and given for

informational purposes only, as the District seeks the recommendations of the Proposer for

PV system type and size that provides the best value to the District. Further site information

is provided in Attachment A and will be accessed via shared folder. Please email

solarRFP@naniaenergy.com with the subject line “Oak Park ESD 97 Solar RFP

Attachment A” and you will be provided a link to access the shared folder.

• Project Financing: The District is seeking to enter into an Agreement with one Proposer to

furnish and install solar arrays under a cash purchase arrangement.

• System Ownership: The District requires that the solar PV systems be owned by the District

upon system commissioning and energization.

• Incentives: The awarded Proposer shall apply for and manage incentives and rebate funding

and renewable energy certificate (RECs) paperwork. RECs will be the property of the District

unless otherwise noted.

• Operation and Maintenance (O&M): The District will be responsible for O&M services for the

life of the solar arrays, and therefore any O&M fees should not be included in base proposal

pricing.

• Monitoring: The District requests a monitoring system for system performance and public

education through our website.

• Performance Guarantee: The successful Proposer shall provide a written guarantee that the

energy or operational cost savings, or both, will meet or exceed within 20 years the District’s

costs under this agreement in accordance with Section 19b-4 of the School Code, and the

Proposer shall agree to reimburse the District for any shortfall.

• Structural Assessment: The successful Proposer shall perform a structural analysis by a

licensed Professional Engineer to determine the suitability of the roof sections to support the

weight of the proposed solar arrays. If it is determined that reinforcements to the roof structures

are required, then the District shall have the option to either 1) add the reinforcements to the

scope of this project with a mutually agreed upon increase to the contract price, or 2) remove

the affected portions of the solar array from the scope of this project with a mutually agreed

upon reduction to the contract price.

2. Scope of Work

The District is soliciting proposals from qualified solar providers for a turn-key installation of a

rooftop solar PV project at the listed site addresses. The goal of this RFP is to identify a qualified

provider with the necessary experience to ensure a fully-managed and well-executed process.

The successful Proposer will have demonstrated experience designing, planning, scheduling,

permitting, constructing, interconnecting, and commissioning a solar PV system. Proposer is

responsible for all permitting and licenses and should include the cost of all permitting in their

proposal. Proposers should be familiar with ComEd regulations, provide project financial

analysis, and have established on-site safety standards. The District reserves the right to modify

the scope of the project at any time prior to contract execution.

See Attachment A indicating available areas for installation. These drawings are meant for

informational purposes only and must be field-verified by Proposer. The Proposer shall develop

a design for new PV systems that provides best value to the District.

2.1. Design Guidelines

Proposer should consider the following guidelines when designing the solar PV system.

(1) Rooftop Solar

It will be the responsibility of the Proposer to assess the building’s structural integrity, roof

condition, and shading limitations.

• Mounting systems shall limit roof penetrations or be fully ballasted. Mounting system

design needs to meet applicable local building code requirements with respect to snow

and wind loading factors.

• Solar system installation must not void the roof warranty.

• Conduit penetrations shall be minimized.

• Systems shall be fixed tilt with an orientation that maximizes annual energy production.

• All roof access points shall be securely locked at the end of each day during

construction.

• System layout shall meet local fire department, code and ordinance requirements for roof

access.

• The successful Proposer must engage with the District’s roofing consultant to perform an

inspection of the roof following completion of the solar PV system.

2.2. Code Specifications

The installation and power generation and transmission equipment shall comply with applicable

building, mechanical, fire, seismic, structural, and electrical codes. Only products that are listed,

tested, identified, or labeled by Underwriters Laboratories (UL) or another nationally recognized

testing laboratory shall be used as components in the project. Construction must comply with

the current adopted Building Code.

2.3. Minimum Warranties

The Proposer must provide their standard system warranty coverage along with specific

equipment warranty coverage for modules, inverter, racking and workmanship.

• Modules: 25-Year Power Output & 10-Year Limited Warranty.

• Inverter: 10-Year Limited Warranty.

• Racking: 25-Year Limited Warranty.

• Workmanship: 2-Year Limited Warranty.

2.4. Inspection and Commissioning

To ensure compliance with all electrical codes, an inspection by an independent commissioning

agent is mandatory after construction is complete and must be included in Proposer’s price

proposal. Commissioning tests shall be included in the final inspection and Quality Control Plan.

The Proposer’s independent commissioning agent shall ensure that:

• All equipment specifications match the proposed equipment specifications.

• The physical layout aligns with the as-built diagrams with variations to proposed system

noted.

• The electrical system as laid out and connected aligns with the as built one-line diagrams

including fuses, relays and switches with variation to proposed system noted.

• Each array passes the open circuit voltage and current test.

• The manual disconnect switch operates correctly.

2.5. System Monitoring

Monitoring of system performance (separate from utility meter monitoring requirements) and

providing public education are two important elements of this RFP. The District requires a
