Photovoltaic System Description

This photovoltaic system consists of (44) Evergreen Solar polycrystalline ES-A 205 watt modules installed in four rows on a Unirac RapidRac ballasted mounting system, facing due south on the fourth floor roof of the Daniel J. Evans Library.

The DC electricity generated is converted to, and synchronized with, the AC power in the building at 208 volts via two Sunny Boy SB5000US inverters, and fed into the building power system through an equipment distribution panel on the fourth floor. Any interruption of utility power to the building will cause the inverters to shut off, per UL 1741. When utility power is restored, after a five- minute wait, the inverters will resume operation automatically.

The performance of the system is monitored through the Sunny Web Box, a communication device that generates a web page that can be viewed by any computer connected by network to the Web Box, and by anyone on the world wide web via the Sunny Portal, a free service of SMA.

The system is self-regulating and normally requires no attention. SMA inverters automatically wake up each day and disconnect from the grid each night. PV mounting at low elevation angles, such as with the RapidRac usually leads to some accumulation of atmospheric dust and particulates at the lower edge of the modules. Due to the Library’s location in a forested area, dust will not be as much of a factor as will pollen. Some gentle cleaning may be needed from time to time.

The system is designed to be in service for decades of clean energy production.

System Design and Production Calculations

The roof of the Daniel J Evans Library offers excellent solar access but there are some obstacles on the skyline. The orientation of the building is 25 degrees East of South, so the clock tower only causes negligble shading. The other skyline object is the HVAC enclosure at the southwest corner of the fourth floor roof. This only causes minor shading near the end of the day from November through January, the darkest time of year. The tree line adds to the late-year losses.

The sun chart below shows the extent of shading. The net loss to this shading is about 2% of the total possible production.

The attached RETScreen model predicts an average production of 9.9 mWh/yr.

Use it to weigh labor expenses and versatility; all customer- any number of options and driven demands that helped engineer this configurations. unique fl at roof solution. www.unirac.com It’s accompanied by a technical support system that provides complete installation and code compliance documentation, an on-line Estimator and design assistance to help you solve the toughest challenges.

26 Beneﬁ ts of Selecting

The RapidRac® G10 was developed through signifi cant computational fl uid dynamics and wind tunnel engineering. The effi cient design, built at a fi xed 10 degree tilt angle, optimizes natural convective cooling of the modules and was designed to meet the requirements of current applicable building codes.

1 Speed of Installation The unique design of the RapidRac® G10 allows installation in less than half the time as the primary competitive products, requiring a 4-page installation guide.

2 Simplicity The RapidRac® G10 requires only 1 wrench and 6 parts to complete the install, a signiﬁ cant reduction over current offerings.

3 Versatility and Choice The RapidRac® G10 accommodates most PV modules, providing the market with tremendous versatility and choice. The ﬂ exibility of design allows it to meet most weight, height and wind conditions. UniRac also offers the RapidFoot®, an optional attachment accessory for the RapidRac® system, designed to provide additional support for higher seismic restraint and ballast trade off.

4 Value The RapidRac® G10 provides a highly competitive price per watt. UniRac estimates that the simplicity and ease of installation could provide labor savings of as much as $10,000 on a 250kw project.

Code Compliant Warranty The RapidRac® G10 system is PE certiﬁ ed.

This bulletin is designed to support applications for • The roof on which the RapidRac™ Mounting System building permits for installations using the RapidRac™ will be installed must have the capacity to resist the minimally attached, ballasted PV Module Mounting System, combined Design Dead Load and Live Load from the manufactured by UniRac, Inc. Follow the seven steps below installed array. and the installation instructions on pages 6 –9 to install RapidRac™ in compliance with the 2006 International Building Code and ASCE 7-05. Before proceeding, note the Step 1. Determine Your Design Wind Speed following: For the United States, the design wind speed is determined • This bulletin addresses seismic, snow, and wind loads. from the American Society of Civil Engineers Standard 7-05, Wind produces the maximum load factor affecting chapter 6, pages 32-33, ﬁ gure 6-1.

Linear interpolation between wind contours is permitted. 3. Islands and coastal areas outside the last contour shall use the last wind speed contour of the coastal area. 4. Mountainous terrain, gorges, ocean promontories, and special wind regions shall be examined for unusual wind condition.

Step 2. Determine Your Exposure Category Step 3. Determine Your Design Wind Pressure The International Building Code, section 1609.4.2, and Design Wind Pressure is the amount of wind pressure that a 1609.4.3, pg. 293 (also referencing ASCE 7, chapter 6) defi nes structure is designed to withstand, expressed here in pounds wind exposure categories as follows: per square foot (psf). To determine the Design Wind Pressure required for your installation, apply the following factors: exposure b Exposure B shall apply where the ground surface roughness condition, as defi ned by the • Basic Wind Speed (determined in step 1), surface roughness classifi cation B existing upwind of • Exposure category (determined in step 2) and the structure in question for at least 2600 feet.

Exposure D shall extend inland from the shoreline for a distance of 6000 feet or 20 times the height of the building, whichever is greater. Surface roughness category D is defi ned as; Flat, unobstructed areas and water surfaces outside hurricane-prone regions, including smooth mud fl ats, salt fl ats, and unbroken ice.
