PW - PEM APPROPRIATE $451,000 FROM THE GENERAL CAPITAL CONSTRUCTION FUND AND AUTHORIZE THE CITY MANAGER TO EXECUTE CONTRACT DOCUMENTS FOR A SOLAR PHOTOVOLTAIC (PV) SYSTEM AT THE SAFETY TRAINING CENTER CITY MGR. MV^; RECOMMENDED ACTION: Adopt Resolution No. 2Q15-Q94 to appropriate $451,000 from the General Capital Construction Fund and authorize the City Manager to execute Contract Documents for a Solar Photovoltaic System at the Safety Training Center. ITEM EXPLANATION: In ongoing support of the city's sustainability and environmental guiding principles, staff has reviewed the potential for installation of solar photovoltaic (PV) energy generation systems at several municipal facilities. Based on its review, staff has identified a feasible location at the Safety Training Center (STC). During construction of the STC, the facility was planned and pre-plumbed to have a solar PV system and the electrical infrastructure was outfitted in a manner to accommodate such a system. On January 13, 2015, the City Council adopted Resolution No. 2015-003 approving the selection criteria and performance specifications to be used in evaluating request for proposals for the design and construction of the Safety Training Center solar PV system. Staff conducted a job walk at the Safety Training Center and four (4) firms attended. Two companies responded to the request for proposals (RFP). One of the companies responding to the RFP turned in an incomplete proposal, which also included a portion of the proposal being submitted after the deadline. Staff evaluated the one proposal from Independent Energy Solutions (lES), and their proposal is in line with both price and net present value of investment (NPV) in comparison to past projects. Project Description lES is proposing to install a 115 kilowatt solar PV system to meet approximately 90 percent of the Safety Training Center's energy needs. The proposed system would include 352 Solar PV panels, and is expected to generate 195,000 kWh/year. The solar panels will be mounted on the roof of the Safety Training Center. An electronic metering system will also be installed to assist in the monitoring of electricity use by the facility compared to the generation of electricity from the solar PV system. The solar panels have a warranty period of twenty five years and an approximate lifespan of thirty years. DEPARTMENT CONTACT: Jesse Zunke 760-434-2992 jesse.zunke@carisbadca.gov FOR CLERK USE.

Independent Energy Solutions EXECUTIVE SUMMARY The purpose of this proposal is to provide City of Carlsbad with the information required to make an informed decision on adding a photovoltaic system to your facility. In response lES entertained a myriad of different approaches in an effort to provide the best overall value. Ultimately we identified (3) major decisions that needed to be considered: Racking, Inverters and Modules. The financial, technical, and process particulars are outlined below. Decentralized vs Centralized Inverters Cost, energy production, and Return on Investment (ROI) are paramount when considering the design and layout of a commercial PV system. Selecting the right technology and applying the most cost/performance-optimized method is the key to creating a best-value proposition for each individual client. In light of best industry practices and evolving technology, PV integrators have moved towards a better model: decentralized commercial rooftop systems utilizing string inverters. For PV plants ranging from 20 kW to 1 MW, this model simplifies installation, increases energy production and lowers long-term costs, adding profit to the bottom line for the City of Carlsbad. Decentralized commercial systems have been the preferred design approach for commercial projects for a number of years due to the following key advantages: 1. Improved Energy Harvest Potential - By using 3-Phase string inverters with higher efficiencies, integrators can immediately realize more energy production. With multiple MPPTs, energy harvest is optimized. Should problems arise, the redundancy provided by multiple inverters preserves system uptime and protects the owner from lost profit. 2. Reduced Install and Transport Cost - Utilizing string inverters, integrators eliminate the need for costly heavy machinery such as cranes and rigging systems. Transport is much simpler and freight costs are lower. 3. Balance of system (BOS) Savings - Shorter DC cabling runs and the elimination of DC combiner boxes save money. Combined, these make a decentralized approach to commercial PV the most cost-effective and profitable method available. 4. Worry-Free Long-term Operation - Every commercial PV system needs an O&M plan. By selecting the most reliable inverters available, O&M can be virtually eliminated. If problems do arise, a longer factory warranty and short replacement product lead time ensure the disruption is at a minimum. In addition, string inverters can be replaced quickly by two electricians in the field, without disconnection or shutdown of the entire array to replace an inverter. This assures continued energy production. CA Lie.

Independent Energy Solutions Racking lES has provided two different approaches the racking and support of the proposed PV system. The first option is a pre-engineered Panel Claw Polar Bear III racking system the second is a custom engineered minimally tilted approach to provide a higher module count. Pre-engineered racking solutions provide the following advantages: 1. Engineering - Panel Claw engineering is much quicker than a traditional custom engineered solution due to predetermined design parameters reinforced by in- depth wind tunnel testing. 2. Installation - The pre-engineered solution arrives pre-palletized and requires no onsite fabrication. This combined with lES's experience installing this product lends itself to a more efficient predictable and higher quality installation. 3. 12° Tilt - The increased tilt results in higher energy yields for the life of the system. The higher tilt also reduces soiling. 4. Serviceability - The inter-row spacing provided by the pre-engineered approach allows individual modules to be easily be accessed and/or removed for serviceability. The ease of access will make any necessary cleaning and/or servicing of the rooftop faster, safer and less invasive to the system 5. The partially ballasted system can be engineered to minimize the number of penetrations on the rooftop and mitigate the risk of future water intrusion. 6. The pre-engineered solution provides a slightly lower NPV than the larger monolithic custom engineered solution however due the increased efficiency it provides higher ROI over the life of the system. These advantages combined with a lower upfront cost make this the preferred approach by lES. Modules Up-front cost vs. overall return (NPV, and ROI) are the primary tradeoffs that determine module selection. lES modeled over a dozen different approaches using SunPower, LG and SolarWorld modules as outlined in the "Overview of Available Options" section of the proposal. Ultimately SunPower provided the highest NPV and when modeled properly using PV SIM it also provided the highest ROI. This combined with the robust warranty, financial stability and high quality of the SunPower product provided lES with information necessary to make a final recommendation of SunPower as the basis of design. * Please see Appendix A for detailed PDF's and explanation of system modeling. * Please see Appendix B for System Layouts CA Lie.

Operating at an efficiency of up to 24%, SunPower solar cells designed with the patented SunPower Maxeon™ technology produce up to 50% more energy per square foot than other solar technologies and consistently outperform other solar technologies in a broad range of real-world conditions, including high temperatures, low light and over extended periods of time. Best Solar Performance in Real-World Conditions • SunPower panels outperform others early in the morning, late in the day, and on cloudy days. • They effectively absorb different wavelengths of light to generate more electricity. • They perform better at high temperatures than others. Because they're more efficient at converting light into electricity (and not heat), the hotter it gets outside, the better they perform compared to the competition. • They maintain efficiency during initial break-in. Most panels lose 3% efficiency when first exposed to sunlight. Not SunPower. From end to end, SunPower guarantees you the highest level of solar energy system performance. Installation is fast to minimize disruption. And SunPower® panels perform. Ten years of comprehensive data show that on average, SunPower® solar panels deliver 105 percent of their expected energy production. Plus, they're built to withstand real-world conditions, so your long-term maintenance costs are impressively low—with an impressively high 98 percent uptime. http://us.sunpower.com/ *Please see Appendix C for product data submittals CA Lie.

COMMISSIONING PROCESS This section sequentially details the commissioning process by commissioning task or activity. 5.1 COMMISSIONING SCOPE MEETING The scope meeting brings together all members of the design, construction, and operations teams that will be involved in the commissioning process. Each building system to be commissioned is addressed, including commissioning requirements, and completion and start- up schedules. During the scope meeting, all parties agree on the scope of work, tasks, schedules, deliverables, and responsibilities for implementation of the Commissioning Plan. 5.2 FINAL COMMISSIONING PLAN The Commissioning Agent finalizes the draft Commissioning Plan using the information gathered from the scope meeting. The initial commissioning schedule is also developed along with a detailed timeline. The timeline is fine-tuned as construction progresses. 5.3 SUBMITTALS The general contractor will provide the Commissioning Agent with a set of equipment and system submittals. This equipment data includes installation and start-up procedures, O&M data and performance data. The subcontractors, general contractor or CP notify the commissioning agent of any new design intent or operating parameter changes, added control Independent Energy Solutions, Inc. - 1090 Joshua Way, Vista, CA 92081 USA Ph: 760-752-9706 - Fax: 760-752-9758 - www.indenergysolutions.com CA Lie.

No.L-11 ROC267938 Independent Energy Solutions Solar Electric Engineering & Construction strategies and sequences of operation, or other change orders that may affect commissioning systems. 5.4 COMMISSIONING CHECKLIST The Commissioning checklist covers all equipment being commissioned. The checklist captures equipment make, model and serial numbers as well as fuse sizes and quantity. Furthermore the checklist confirms the installation of equipment per plan and the quality of the system install. This is a "no load" test, however AC power from the grid/utility is required to complete the inverter installation checklist as well as the Data Acquisition System (DAS) programming and testing. The inverter will not be allowed to generate power during this phase of testing. 5.5 EXECUTION OF COMMISSIONING AND TESTING The Commissioning Agent schedules operating tests through the General Contractor and Subcontractors. The commissioning agent performs all tests and records the result. Any deficiencies found during testing will be documented in a Deficiency Report. The report will include all details of the components or systems found to be non-compliant with the parameters of the functional performance test plans and design documents. The deficiency report will become part of the punch list. The report will detail the adjustments or alterations required to correct the system operation, and identify the responsible party. The deficiency report will be continuously updated. The Commissioning Agent schedules any required retesting through the General Contractor. Decisions regarding deficiencies and corrections are made at as low a level as possible, preferably between commissioning agent, sub-contractor and general contractor. 5.6 OPEN SYSTEM TESTING The purpose of the open system test is to verify the condition of the wiring for each string both positive and negative. This test determines the quality of the insulation, and the polarity of the string. This test is to be performed prior to startup of the system, at each combiner box. The meter is attached to each individual positive wire in sequence, followed by testing of each negative. Conditions during test must also be recorded, irradiance, time, and temperature. This test also records the quality of the conductor insulation for the remainder of the system. The results are recorded in the commissioning report; any issues found will be reported to the GC for correction. As this is a "no load" test, AC power from the grid/utility is not required. The inverter is not powered up during this testing phase. 5.7 OPERATING SYSTEM TEST 5.7-1. OPERATING SYSTEM TEST This test is to be performed with all negatives and positives landed at each combiner box and the inverter. Again the site conditions must be recorded during this testing; irradiance, time, Independent Energy Solutions, Inc. - 1090 Joshua Way, Vista, CA 92081 USA Ph: 760-752-9705 - Fax: 760-752-9758 - www.indenergysolutions.com CA Lie.

At this time the inverter and combiner disconnects will be in the closed position. Each string in the combiners must now be voltage tested and amperage tested for performance of the system based on conditions. This is a full load test of the entire Solar PV system. AC power from the grid/utility is required to complete this test. The inverter will be fully functional during this test and will generate power during this test. The system will need to operate through a full cycle to complete this test. This test requires a 24 hour period of operation to complete. 5.7-2 OPERATING INVERTER TEST All components of the PV system are now in operation. This test is done to verify proper function of installed equipment. The inverter voltage on both AC and DC side are recorded. All readings available from the inverter display are verified and recorded. The time, date, serial number and set points are all verified. Thermo graphic data is recorded during this testing phase. As with the other tests the conditions during testing must be recorded; irradiance, time, temperature and wind speed/direction. This is a full load test of the entire Solar PV system. AC power from the grid/utility is required to complete this test. The inverter will be fully functional during this test and will generate power during this test. The system will need to operate through a full cycle to complete this test. This test requires a 24 hour period of operation to complete. 5.8 REVIEW TEST DATA The CP will receive the data recorded by the CA and review all the information gathered. All data will be verified compared with estimated performance by the CTA to ensure the quality of the installation and the accuracy of the engineering estimates of the installed system. Once the CTA is finished with the review, he will hand the data off to the CP to compile the final commissioning report for the customer. 5.9 COMMISSIONING REPORT A final Commissioning Report will be compiled which summarizes all of the tests, findings, and documentation of the commissioning process. The report will address the actual performance of the PV system in reference to the design documents. The commissioning report includes: • An evaluation of the operating condition of the systems at the time of test completion • Deficiencies that were discovered and the measures taken to correct them • Functional test procedures and results • Reports that document all commissioning field activities as they progressed 5.10 OPERATIONS AND MAINTENANCE MANUALS The operation and maintenance manuals prepared by the contractors for the owner's maintenance personnel are reviewed for completeness. The contractors are encouraged to submit O&M manuals at the earliest possible date. Materials may be added, or requested from Independent Energy Solutions, Inc. - 1090 Joshua Way, Vista, CA 92081 USA Ph: 760-752-9706 - Fax: 760-752-9758 - www.indenergysolutions.com CA Lie.

For each training session, the contractors provide a detailed agenda for each piece of equipment or system for which training is required. The agenda describes the training scope, duration, and methods, along with the name and qualifications of the trainers. The commissioning agent develops a plan for including in the training session contractors and/or trainers from different disciplines, when appropriate. The trainer documents each training session (duration, general subjects covered, and attendees). The commissioning agent may witness any of the training sessions. 6.
