A. Part 1.PMC can save manufacturers time and money.  In the late 70s through the mid 80s the qualification test standard around the world was JPL Block V. This been replaced by the CEC 503, IEC 1215, and IEC 1646. While these are excellent standards, European countries, plus some Middle East and African countries are […]

A. UL 1703UL 1703 IS A SAFETY STANDARD FOR PHOTOVOLTAIC MODULES AND PANELS. UL provides evaluations and certification to UL 1703.  Manufacturers whose products meet these requirements are authorized by UL to apply the appropriate UL Mark.  Product manufacturing is then audited through a program of factory Follow-Up Services.  To counter-check products bearing the UL […]

A. A multi-client testing program at the ASU Photovoltaic Testing Laboratory (PTL) involves conducting PV module tests (per IEEE 1262, IEC 1215/1646, and/or UL 1703) for two to six module TYPES (i.e., models), generally from different clients, at the same. Cost savings of 25% to 50% are provided by multi-client testing. Test results are always […]

A. We need a total of nine modules for IEEE 1262/IEC 1215. A total of 11 modules are required for UL 1703. The same 11 modules can be used for IEEE 1262/IEC 1215. For a 0.7m^2 module, the cost for IEEE 1262/IEC 1215 is $21,333 for our July 15 multi-client test program.

The Photovoltaic modules you put on your building must have the Underwriters Laboratories seal. Too, the module’s design should have been qualified to either the IEEE 1262, IEC 61215 or IEC 61646 standards. UL safety listing, of course, assures the local electrical inspector will approve what you have chosen to install. The National Electric Code […]

Which way should the array face? The rule of thumb is always face the array true South (in the Northern Hemisphere). Oh, there may be exceptions, such as your immediate neighbor to the east is a thousand foot high mountain, and it keeps the sun away from your place until noon every day. Sure, there […]

A properly designed photovoltaic (solar electric) system will work, and work well, for years. But you as the builder, and your customer, the homeowner, shouldn’t expect more of the system than it can provide. Whatever system is chosen, even the simplest will need homeowner maintenance. To generate The generation of green electrons today, at this […]
