 <u>Comment:</u>
 To date the efficiency and reliability of “thin-film PV-modules” does not yet measure up to the standards of crystalline PV cells, and the price reduction is also still not convincing. In spite of that fact, this option might be feasible for future applications, especially for low-cost Solar Home Systems.<br/>The World Bank has already allowed the use of thin-film PV modules in their Indonesian SHS project tender, but only one company (Canon, Japan) offered these kinds of modules in their quotation.
 <u>Optional</u>:
 If thin-film photovoltaic modules are used, they must be product-tested and certified in accordance with IEC 61646. The peak power output for thin-film modules should be the value after light soaking.
@@ Line 25: / Line 25: @@
 The minimum acceptable operating voltage at '''MPP (Maximum Power Point)''' of the PV module shall be no less than 16 V<sub>dc</sub> at a cell-operating temperature of 60° Celsius.
 <u>Optional:</u>
 Each module shall comprise not less than 36 series-connected single- or polycrystalline silicon solar cells.
 <u>Comment:</u>
 In order to allow a full charge of a 12 V battery under “controlled gassing” conditions, a voltage of 14.5 to 15 V must be available at the battery terminals. Including voltage losses via cables (0.5 to 1.0 V) and blocking diodes (0.4 V/Schottky diode), the PV generator voltage should be at least 1.0 to 1.5 V above that maximum battery voltage. Under certain conditions, e.g. with the use of sealed batteries (no gassing allowed), very low system losses or permanently low ambient temperatures, this value might be lower, and even PV modules with less than 36 cells might be used. But a PVgenerator voltage of 14 - 14.5 V as recommended in the “Universal Standard” Proposal [1] will definitely be too low for SHS applications in tropical countries.

 *The module(s) shall be equipped with a sealable waterproof (international protection code IP54) terminal (junction) box. The poles inside shall be clearly marked. A strain relief for the cables must be provided.
 <u>Optional:</u>
 The junction box must have outlets that allow for attachment of flexible conduit pipes. If the module does not have a junction box which allows for a direct conduit connection, a weather-resistant junction/combiner box must be attached to the support structure.

 for system voltage greater than 50 V: The PV modules must have bypass diodes to offer protection against hot spots in case of partial shading. The PV modules shall have a frame of non-corrosive material, e.g. anodized aluminium or stainless steel. The frame shall ensure that the module is resistant to torsion during handling and extreme weather conditions.
 <u>Comment:</u>
 Only solid, framed modules are applied for SHS and RHS. At certain sites and for certain applications flexible, unframed modules may be preferred (e.g. tents of nomadic tribes). However, up to now no experience for this module type under rural conditions is available.
