;In order to accelerate the popularization of solar photovoltaic systems in Tai-wan, for its easy combination with the appearance of the existing building structure, the government has deregulated many policies and relative laws.However, the top-ic is that whether the system to be built can achieve the expected performance, or its maintenance costs will be cheaper than what expected. More forword, if the SOP(Standard Operating Procedure) for its standard inspection could be imple-mented to guarantee the construction quality of this system; as well as if the system design and the protection device is considered not to impact on the Taipower sys-tem, etc., all these subjets mentioned befor are points that must be reviewed and studied.
This study is focused on the most extensive used Grid-Connected systems in solar photovoltaic system market, and the relative investigation on its equipments failure rate and the cause of the malfunction, collecting research informations around the world about the failure of the solar photovoltaic system, and designing questionnaire to investigate, making statistics and ranking failure rate of solar pho-tovoltaic system equipment presently in Taiwan, after analyzing possibilities of failures reviewing if circumspect the current regulation of Public Construction Commission(PCC) specification. In case of deficiencies or omissions, then re-ferring to regulations and standards established by Industrial Technology Research Institute (ITRI ) , Chinese National Standards (CNS), National Communications Commission (NCC), to develop countermeasures and induct amendment or new terms to the ITRI regulations.
In addition,this study will rest on the norms establishment, include those new terms and amendement that would be added for each stage of pre, during and af-ter-construction to the checking table; the qualitative part is collection of relative norms , in the quantitative part it will compare the regulation specification values from different unit , adopt the most stringent standards. If there is no norms on qualitative and quantitative parts, the object will be focused on the improvement of malfunction adding advisable terms that this study suggest. Furthermore, ITRI and PCC’s those existing solar photovoltaic norms that need not amendment will be in-corporated, that represents the completeness of checklist to serve three quality con-trol unit in favor of pre-construction, during and after this construction inspection checklist as the basis can be. After the setup is complete, the inspection data also enhance the future availability in industry, government, academia, research sections, avoiding repetitive errors, reducing failure frequency, improving system quality.
In order to verify the applicability, circumspect nature, preventivity of the checklist in this study , promoting the spirit of ISO 9000 - ”anyone can enter at any time to take over the situation,” the object to be verify must include the first contract and contact local authorities of solar photovoltaic systems unit owners, commis-sioned supervision unit design and supervision of, and even the initial investment in setting public works solar photovoltaic systems of manufacturers, as long as the ba-sis of this checklist prior to construction, during and after the program individually vetting submittal documents, equipment specifications, construction projects and warranty transfer data will be able to reach the three projects will require the quality control standards.
On the other hand, those who has experiences of being contracted by the Minis-try of Economic Affairs for solar photovoltaic systems construction, if applying this checklist on the construction process, it will assure not to repeat previous erros, in addition to reduce construction period and costs caused by repeated construction.
