Photovoltaic　(PV)　facilities　are　sustainable　and　promising　approaches　for　energy　harvesting,　but　their　applications　usually　require　adequate　spaces.　Road　structures　account　for　a　considerable　proportion　of　urban　and　suburban　areas　and　may　be　feasible　for　incorporation　with　photovoltaic　facilities,　and　thereby　have　attracted　research　interests.　One　solution　for　such　applications　is　to　take　advantage　of　the　spare　ground　in　road　facilities　without　traffic　load,　where　the　solar　panels　are　mounted　as　their　conventional　applications.　Such　practices　have　been　applied　in　medians　and　slopes　of　roads　and　open　spaces　in　interchanges.　Applications　in　accessory　buildings　and　facilities　including　noise/wind　barriers,　parking　lots,　and　lightings　have　also　been　reported.　More　efforts　in　existing　researches　have　been　paid　to　PV　applications　in　load-bearing　pavement　structures,　possibly　because　the　pavement　structures　cover　the　major　area　of　road　structures.　Current　strategies　are　encapsulating　PV　cells　by　transparent　coverings　to　different　substrates　to　prefabricate　modular　PV　panels　in　factories　for　onsite　installation.　Test　road　sections　with　such　modular　solar　panels　have　been　reported,　where　inferior　cost-effectiveness　and　difficulties　in　maintenance　have　been　evidenced,　suggesting　more　challenges　exist　than　expected.　In　order　to　enhance　the　power　output　of　the　integrated　PV　facilities,　experiences　from　building-integrated　PVs　may　be　helpful,　including　a　selection　of　proper　PV　technologies,　an　optimized　inclination　of　PV　panels,　and　mitigating　the　operational　temperature　of　PV　cells.　Novel　integrations　of　amorphous　silicon　PV　cells　and　glass　fiber　reinforced　polymer　profiles　are　proposed　in　this　research　for　multi-scenario　applications,　and　their　mechanical　robustness　was　evaluated　by　bending　experiments.　©　2021　by　the　authors.　Licensee　MDPI,　Basel,　Switzerland.
