Proposal for 2500 Watt Grid Intertie-Only Solar Electric Generation System (No Batteries)

Project Site:
Site Location:
System Type:	Utility intertie w/ net metering, no battery back-up, 48 VDC nominal input, 240 VAC output
Total Array Power:	2,520 Watts Peak DC
Mounting:	Pole mount, fixed azimuth. (Roof mounting also available)
Solar Access:	Unobstructed south facing area available
Estimated Energy Production:	3,650 kwhr/year, based on Northern California Average Solar Radiation in non-coastal areas

We are very pleased to present our proposal for a solar electric generation system components to be installed at your residence, per the above system parameters. All Components are certified for the CEC Buydown Rebate Program.

1. Quantity 24, Photowatt PW1000-105 Solar Modules that feature 200-micron high efficiency multi crystal cells, tempered glass construction, high strength anodized aluminum frame, dual bypass diodes, and integral weather resistant conduit ready junction box. Please review the attached manufacturers data sheet for further specifications.

These 24 modules are to be wired in 6 series-strings of 4 modules each. Each series-string output is a nominal 48 VDC. Made in the USA.

Module Peak Power Rating: 105 Watts Total Array Rating: 4,200 Watts Panel dimensions: 52.56 in x 26.5 in x .96 in. CEC Buydown Module Rating: 94.6 Watts. Total Array Area Required for 40 panels: 400 sq ft Mfg. Warranty: 25 Years

 

2. Quantity 2, UniRac U-PT/160M, 6" Pole Mount Module Racks, which feature lightweight, corrosion resistant, and durable aluminum construction. There are no painted steel components that can rust. All hardware is stainless steel or zinc plated to provide maintenance free racks for a lifetime. Made in the USA.

Number of modules per rack: 12 Material: Aluminum Structure, SS Hardware Tilt Angle: Adjustable to terrain Units to be pole mounted, facing south Unit Ship Weight: 162 lbs Six roof mounting racks available at the same cost

 

3. Quantity 1, Trace Engineering STXR2500 Sun Tie Inverter which feature Maximum Power Point Tracking (MPPT) software, peak efficiency to 94%, LCD data panel, factory installed DC and AC input/output breakers, combination DC and AC lightning arrestor, and PV ground and fault protection system. UL Listed. Made in the USA.

Continuous Power Output: 2.5 kVA (2500 Watts) AC Voltage Output: 240 VAC Nominal Input: 48 VDC Nominal Peak Efficiency: 94% Should be mounted in a dry, cool environment Ask for spec sheet for further details. Combiner Board: 6, 20-amp fused sub array inputs Mfg. Warranty: 5 Years Factory Extended (includes 3 year add-on from Trace) Unit Ship Weight: 40 lbs each

The California Energy Commission (CEC) Emerging Renewables Buydown Program rebates will reduce the net cost of the above system components by $9,603.00. This figure is based on the CEC certification ratings of 94.6 Watts for the Photowatt PW1000-105 Modules, and 94% efficiency for the Trace STXR-2500 Inverter. The CEC certification rating of 94.6 Watts/module is based on PTC (PVUSA Test Conditions) power rating which is more conservative than the STC (Standard Test Conditions) power rating of 105 Watts listed in the manufacturers specifications. The above rebate estimate is therefore based on 24 modules at 94.6 watts each multiplied by the inverter efficiency of .94 equaling 2,134 Watts CEC Certified System Rated Output. The CA Buydown rate is $4.50 per watt, or 50% of the system cost, whichever is less.

* Available in CA only. The applicable Buydown for this system is $9,603.00, which is the net output rating of this system times $4.50/ watt. Your added cost of labor to install the system will increase the overall system cost so that you will qualify fully for $4.50/ watt. You will receive a check directly from the State of California after you have completed the installation and presented a copy of the signed-off building permit.

Included in the system component pricing above are the following services:

• Design consultation
• Assistance with CEC Buydown rebate application (in California)
• Assistance with utility company intertie agreement (in California)
• Assistance with local permitting authority, if located 45 minutes from Santa Cruz, CA
• Technical support to your electrical and mechanical installers
• Customized operation and maintenance owners binder
• Owners training in system operation and maintenance

Not included in this proposal unless arranging installation through Solar Technologies:

• Mechanical and Electrical Installation Labor (by owner and/or contractor(s)).
  (If you are local to our area, we will arrange installation of this system for approximately $4,400)
• Rain shield for inverter, if it is to be mounted outside.
• Wiring, conduits, and other electrical connection hardware
• Rack mount roof bolts, standoffs, and roof penetration sealing hardware, if mounting on roof.
• 6" Sch 40 steel pipe, if doing a pole mount
• 5 Year System Labor Warranty, required by the CEC of a contractor for rebate fulfillment (unless we install the system)
• Permitting assistance, permit fees, and any special engineering or drawing requirements

Delivery: 3-4 weeks ARO

Quotation Validity: 30 days

Terms: 50% with order, balance due on delivery, Cash, Check, or Credit Card Accepted (small surcharge added for credit card payments)

Notes: Prices subject to change without notice. Pictures above are representational. Details of actual hardware delivered may be slightly different. We reserve the right to substitute PV collector of equal or better quality and power generation characteristics.

Thank you again for the opportunity to provide this proposal. We will look forward to working with you on this project and will do everything possible to exceed your expectations and insure your lasting satisfaction!
