The system has been installed in the village of Azaghar, in the Community of Tassift, Chefchaouen. The final installed capacity has been smaller than foreseen because the final demand was less than initially estimated.<br/><br/>02.<br/><br/>INSPECTION<br/><br/>Firstly, the quality of all the equipment was verified and the specifications were checked. During the installation, the name of the manufacturer, the type of product and the serial numbers were registered. Once the equipment was installed, the next step was to verify every component performance before the commissioning following the manufacturer instructions and with the supervision of the technical project manager. All the prototypes had already been tested in the laboratories by the project partners involved (CDER, NERC, SASSO, FRAUNHOFER, LSES).<br/><br/>03.<br/><br/>PV MODULES<br/><br/>Before verifying the PV modules, the structure to fit and install the modules will was reviewed, checking the lengths, type of material, every electrical connection, and all the details related to the constructive specifications. The stability of the structure was also verified, as well as the final orientation and inclination of the PV generator. No shading was found in the PV generator. The strength of the PV modules unions to the structure were checked and all electrical connections were checked: module series, earthing and the whole generator. As it is always recommended, the test was taken in a clear day in which the radiation received on the PV generator was acceptable.<br/><br/>Once the radiation was checked, the following values were registered: · · · Open circuit voltage Operating point current Operating point voltage<br/>page 3 of 15<br/><br/><br/>·<br/><br/>Short circuit current<br/><br/>The performance test of the PV generator was correct and without any remark.<br/><br/>04.<br/><br/>CONTROLLER<br/><br/>The voltage operational range of the controller was configured and registered. The efficiency of the charger was above 80% and no problems were found.<br/><br/>05.<br/><br/>INVERTER<br/><br/>The output voltage was measured and was correct. The voltage and the frequency were registered for every test load.<br/><br/>06.<br/><br/>BATTERY<br/><br/>The installation of the battery, the connections, the position and the temperature sensor were verified. A discharge test was done with a test load of 2.000 W, disconnecting the PV generator and measuring density and voltage for every cell. The values of the cells where similar and correct. There were no visible sediments, no corrosion in the plates of the cells, electrolyte levels were correct, the connections were clean and the terminal surfaces were properly greased and protected. In addition, the availability of the accessories and technical instruments for the maintenance (distilled water, densimeter and funnel) was checked.<br/><br/>07.<br/><br/>PERIPHERALS AND DATALOGGER<br/><br/>The performance and led lights of the remote visualization panel was checked and all the measures and information shown was correct. A laptop computer was connected to the datalogger and all the communication tests were satisfactory and the registration of the data is working. Also, the signals were tested: reference cell, ambient temperature and battery temperature.<br/><br/>08.<br/><br/>DISTRIBUTION GRID<br/><br/>The voltage losses were registered, lengths and sections of the distribution grid. No electrical problems were found.<br/>page 4 of 15<br/><br/><br/>09.<br/><br/>PUBLIC LIGHTING<br/><br/>Every component of the public lighting was verified. The lighting was configured by electrical ballasts in order to reduce the load at late hours. The electronic switches to activate and deactivate the public lighting were checked and the condition was satisfactory.<br/><br/>10.<br/><br/>ELECTRICAL CONNECTIONS TO USERS<br/><br/>Every connection was inspected. For every one, the performance of the dispenser meter was verified, as well as the protections and the user satisfaction with the installation. The name of every user and connection were registered on the community map drawings.<br/><br/>11.<br/><br/>EARTHING SYSTEM<br/><br/>The resistance and the conductivity of every metallic frame of the PV generation was checked, as well as the metallic parts of the electronic devices, controller and inverter registering longitudes, sections and ground resistance.<br/><br/>12.<br/><br/>GENSET<br/><br/>The output voltage was measured and the accurate value demonstrated that the genset operation was correct. The voltage and the frequency were registered for every test load. The availability of the accessories and technical instruments for the maintenance was checked.<br/><br/>13.<br/><br/>COMMISSIONING<br/><br/>Every test described bellow was archived for further consulting and the final conclusion of the test was &quot;CORRECT INSTALLATION&quot;. All the datasheets of the manufacturers were included for further consulting and maintenance. Once the generator has been tested, the whole system was interconnected in order to test the global performance (without household loads) during 3 days. After that, verifying all the measures and values are correct, the whole generator was connected to the distribution grid and the loads. All the data registered by the datalogger in the following days were correct showing a correct performance of the whole system. The documentation is archived in 4 main documents:<br/>page 5 of 15<br/><br/><br/>·<br/><br/>Datasheet for identification, configuration and characteristics: data concerning to the installation process and the specification of the devices of the system: PV generator, battery, controllers and inverter (see Annex A). Datasheet for inspection, tests and verifications: data concerning to calculations and measures of the performance of the system and guideline for the periodical maintenance and regular inspections (see Annex B). Datasheet for electrical connections: data concerning to the correct electrical service in every household electrical connection after the commissioning (see Annex C).<br/><br/>·<br/><br/>·<br/><br/>14.<br/><br/>MONITORING AND FOLLOW UP<br/><br/>The following pages contain the datasheets and the processed information are attached. This information has been generated by the datalogger and by the specific software GIFA TApS partially developed within the scope of the project.
