NOVELTY - The apparatus has a preheater which is provided for preheating a lay-up of a solar cell module (10). The preheater is provided to be a dedicated localized heating unit (11) for locally preheating the lay-up. The dedicated localized heating unit is arranged to pre-heat a cross-connector region (22) of lay-up. The dedicated localized heating unit is provided to heat by radiation. A support is configured for supporting or conveying the lay-up so that the dedicated localized heating unit is located in the support. A laminator is provided for laminating the lay-up.    USE - Apparatus for preheating lay-up of solar cell module used in manufacturing sandwiched unit such as solar panel.    ADVANTAGE - Since the preheater is provided as a dedicated localized heating unit for locally preheating the lay-up, the costs for the equipment can be reduced drastically as no homogenous heating is needed for the entire module during preheating so that the construction can become lighter while saving the material and costs. Thus, the energy is saved because not all material is heated so as to be adapted for mass production inexpensively. Thus, the apparatus is simple, cost effective, reliable, and environmentally friendly in operation. Since the operation of the preheating and laminating is preferably synchronized, the energy consumption is reduced effectively. Since the energy source such as LEDs, carbon filament lamp or heating coils is used to provide local preheating by a dedicated localised heating unit whose extent is limited to those areas of the solar module where cross-connectors are placed, the overall amount of heat transferred is reduced while preheating the portions needed to be preheated so that the sources can be switched on/off quickly and are instantly ready for use so as to allow fast control of heat energy sent to the laminated object. Thus, the energy can be saved with the increased throughput.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for laminating lay-up of solar cell module.
