Executive Summary

This document outlines a proposal for a solar photovoltaic project developed on behalf of South Lane School District that will benefit from a grant through Emerald Public Utility District Green Grant offering in June 2015.

The project offered in this application is for a 10kW photovoltaic array to be installed at Cottage Grove High School. The project financials are summarized below:

The project will gain some efficiencies for being included under the existing Ameresco ESPC contract, but can also be self managed by the School District.

Installer Cost 42,000$      

Contingency (5%) 2,100$        

Ameresco Project Management 2,520$        

Total Installed Cost 46,620$      

Grant Ask 40,000$      

Remaining to be Financed from ESPC project contingency 6,620$        

Project kWh annual production 11,380 kWh

Annual production savings 857$

Project Description

The project will be a 10kW photovoltaic panel installation on the roof of the science wing at Cottage Grove High School. The project will consist of thirty three (33) Solarworld SW 315 mono crystalline photovoltaic panels. The project will be net-metered so that electricity produced by the panels will flow into the building meter, and will offset electrical usage at the facility. Application for the Net Metering Service will be coordinated with Emerald PUD as per ORS 757.300.  The project mission goals are as follows:

Develop and promote awareness of sustainability and new technology within the students and faculty at South Lane School District as well as the community. 

Demonstrate a commitment to sustainability and the development of new technology. Participate with Emerald PUD in the larger mission of development of environmentally sustainable

energy sources that will reduce our dependence on fossil fuels, and improve greenhouse gas emissions. Provide a financial benefit for the South Lane School district. Reduced utility costs will allow the District

to focus resources into the classroom. The project location is at 1375 S River Road, Cottage Grove, OR 97424. The project will be installed roughly in the following location adjacent to an existing 1kW demonstration project performed by EPUD.

The project will be implemented by a qualified turn-key installer with proven experience in grid-tied small and medium solar installations. The siting of the project was selected so that it will minimize risk and operational cost to the district, minimize impact to the facility, and provide maximum utilization of the solar resources.

Cottage Grove High School was selected for siting for the following reasons o Safe and code compliant modern roof structure. o Standing seam metal roof offers attachments to the PV array that reduce the number of through

penetrations and maintenance concerns compared to built-up or conventional shingle systems. o Facility electrical demand is high enough to use 100% of the array production throughout the

year. o Access to the array is on the first story of the building, and is south facing and is unshaded. o The electrical infrastructure is modern and can accept modifications without substantial upgrade.

The copy of the installer’s proposal. Also included in the supplemental attachments are a sample design that is offered by Sunlight Solar.

Project Evaluation

The criteria for a successful project are as follows:   The project is used to promote sustainability with the school curriculum - science of photovoltaic panels,

offer insight into careers in renewables, and to create excitement or passion about sustainable future. Demonstrate to the community responsible stewardship of district resources. Show the district’s and PUD’s continuous commitment to sustainability. A successful project will use quality components and will present the lowest possible operation and

maintenance costs to the district. A successful project will be installed by professional installers to the highest safety standards, under the

most stringent codes, and will offer the highest quality of design. A successful project will use products and labor from Oregon that will benefit the Oregon economy.

The S-5-S and S-5-S Mini clamps are each furnished with

the hardware shown to the right. Each box also includes

a bit tip for tightening setscrews using an electric screw

gun. A structural aluminum attachment clamp, the S-5-S

is compatible with most common metal roo#ng materials

excluding copper. All included hardware is stainless

Be at least 1.00” high.

Have a height distance less than or equal to 0.25”

between the male portion of the panel and female

portion of the panel.
