Bur, through nc~ site inspection <br />conducted be IiS, it ~cas found chat each rooftop had a shading concern due ro rooftop eyuipmeut and <br />ti>ur buildings had tree foliage shading. Ii ~~ as determined that nc~ optimal south facing rooCiops for <br />PV' installation include atop nc~ Yarls l~eparnnent, Streets llepariment, Se~cer Ihparnnent, and \V~ater <br />llcparuncvt Buildings.

Fur <br />comparison purposes, the annual energc usage estimated for each site is also sho~c-n in Table I~:S L. <br />Table 1: Estimated Energy Usage and PV Electricity Generation <br />"~`'°"`~"°~'°'°""° 603 89 122 <br />Center (OSC) <br />Well No. 8 691 275 375 <br />there arc mam- financing options that the Citc ut Pleasauum can utilize ro fund their PV' scstcm. <br />'1'hcsc options include a Third pare- PP:A, leasing nc~ scstcm, and loo interest lo;ms. lincrgc Solutions <br />recommends that the Citc of Pleasanton explore a third parn~ PP:A or leasing arraugenuni since this <br />~s ill alk>~c the cite to take advantage of the federal tai a~edir and accdertted depreciation. l~he Guaucial <br />auaksis has dcicrmined an after uts annbincd'J"~, internal rate of return, ~chich is in line~~ith third <br />parn~im-cstors cvpcctations. <br />1~here appear w be uu silntitiauu barriers regarding Pt' teehnologc, interanumciion, or site <br />characteristics at nc~ OSC.
