Abstract: A PV module frame, includes a module recess, a sidewall vertical to the module recess and a bottom portion vertical to the sidewall. The bottom portion extends from the bottom of the sidewall along the opposite direction of the recess of the module recess. A PV module having the PV module frame and a PV module installation system for installing the PV module onto a support, wherein the bottom portions of the adjacent solar cell assemblies are socket jointed and fixed to at least one installation beam which is fixed to the support. The beneficial effect of the present invention is that: fast installation of a PV module could be realized only by using the improved frame and one installation beam, Which reduces the quantity of the members in an installation system module and makes the installation more efficient, easier and more economical.

Abstract: The present invention discloses a PV module frame, comprising: an module recess, a sidewall vertical to the module recess and a bottom portion vertical to the sidewall. Said bottom portion extends from the bottom of said sidewall along the opposite direction of the recess of said module recess. The present invention also discloses a PV module having said PV module frame and further discloses a PV module installation system for installing said PV module onto a support, wherein the bottom portions of the adjacent solar cell assemblies are socket jointed and fixed to at least one installation beam which is fixed to said support. The beneficial effect of the present invention is that: fast installation of a PV module could be realized only by using the improved frame and one installation beam, which reduces the quantity of the members in an installation system module and makes the installation more efficient, easier and more economical.
