Off-grid solar installation inspection report for Yap. The aim of the inspections carried out by the REP-5 Programme Management Unit (PMU) over the period of November 2008 to March 2009 in Pohnpei, Chuuk and Yap was to ensure that the supply and installation of the 161 off- grid PV systems were done. The PV systems were designed and implemented as rooftop installations at seven sites; as flat roof installations at six sites; and as ground-mounted installations at three sites. The report covers various things like identifying variation between what was included in the contract and what was supplied and installed; the quality of installation with respect to best practice; any design problems encountered; actions that need to be taken by the Contractor; actions that need to be taken by other actors in the project.
