| Summary: | The aim of this work is to improve the safety of photovoltaic (PV) systems by preventing the spread of PV fires through the use of coating solutions such as intumescent coatings on backsheets and benzoxazine resin on tempered glass. This study focuses on analysing the properties of the backsheets of solar panels. Five properties of backsheets are analysed: its ability to adhere to coatings, its decomposition temperature, glass transition temperature, melting temperature and heat release rate. Such properties are crucial for the selection of coatings suitable for the backsheets. Additionally, this study also focuses on the effectiveness of benzoxazine resin applied to tempered glass used in solar panels. Contact angle was carried out on both backsheets and tempered glass. Additional tests like the thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and cone calorimetry were conducted for the backsheets, while flame test was conducted for the tempered glass instead. It is demonstrated that it will be harder to adhere coatings on backsheets compared to tempered glass. Also, intumescent coating and benzoxazine resin are effective in preventing fire spread and can potentially be incorporated into PV systems. The application of such coatings will allow thinner tempered glass to be used, reducing the weight of solar panels while allowing solar panels to meet fire standards in Singapore. Benzoxazine resin coated on tempered glass shows promising results as experiments show that the addition of the resin reduces heat transfer. This will provide more time for people to be saved if PV fires were to happen. |
