Solar battery module and method of manufacture thereof
A solar cell module having a good appearance after lamination and a method for producing such a solar cell module are provided by specifying the combination guideline for encapsulants capable of bettering the appearance after lamination. The solar cell module contains an upper protective material (A), an encapsulant (B) for use on the side of the upper protective material (A), a solar cell device (C), an encapsulant (D) for use on the side of a back sheet (E), and the back sheet (E), wherein the encapsulant (B) and the encapsulant (D) satisfy the following requirement (P), and the production method produces the solar cell module. Requirement (P): The flow beginning temperature (TB) (° C.) of the encapsulant (B) and the flow beginning temperature (TD) (° C.) of the encapsulant (D), as measured under a load of 1 kgf/cm2, have the following relationship: TB−TD>0 (° C.).
