A controller controls a first inverter drive circuit and a second inverter drive circuit. The first inverter drive circuit drives a load having a load current larger than the second inverter drive circuit. The first inverter drive circuit includes a control ground terminal and a drive ground terminal which are isolated from each other. The ground terminal of the second inverter drive circuit is connected to the ground of the controller. The control ground terminal of the first inverter drive circuit is connected to the ground of the controller. The drive ground terminal of the first inverter drive circuit is connected to the negative side of the first inverter circuit.

A solar cell encapsulant sheet including a resin layer (S) formed of a resin composition containing an olefine-based resin, wherein the storage elastic modulus at 25&#xb0; C. of the resin layer (S) is 200 MPa or less, at least one surface of the resin layer (S) is the sheet surface of the encapsulant sheet, and the sheet surface satisfies the following requirements (a), (b) and (c): (a) the dynamic friction coefficient on a tempered white glass plate is 1.5 or less, (b) the surface roughness Rzjis is from 0.1 to 50 &#x3bc;m, and (c) the static friction coefficient on a tempered white glass plate is 1.5 or less.

Sealing sheet for solar cell

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) (&#xb0; C.) of the encapsulant (B) and the flow beginning temperature (TD) (&#xb0; C.) of the encapsulant (D), as measured under a load of 1 kgf/cm, have the following relationship: TB&#x2212;TD&#x3e;0 (&#xb0; C.).

Solar battery module and method of manufacture thereof

A decorating method includes the steps of coating a base material with a coating composition comprising 45-95 parts of urethane methacrylate, 1-50 parts of a compound having at least an intra-molecular radical polymeric double bond, and 0.1-15 parts of photopolymerization initiator. The coating is hardened to form an under coat. Vacuum deposition of indium and/or tin in a crystalline structure-independent way is performed to form a non-conductive thin film. Then, a UV-hardening resin, poly acrylic-urethane resin, or acrylate-silica resin is applied, which is hardened to form a hard coat layer.
