Due to the fact, that there is no standard fully covering PVT Hybrid collectors or a standard
mentioning PVT’s (neither within EN 12975-1 or -2 nor within IEC 61215; 61646; 62108; 61730),
there’s a need of additional requirements within Solar KEYMARK Scheme Rules to ensure a
harmonized procedure within the third parties involved in the Solar KEYMARK certification.
PVT Hybrid collectors can get a Solar KEYMARK certification if the following
requirements are fulfilled:
-
-
-
Full certification of the PVT Hybrid collector/module (not only the PV-module) by an
accredited and IECEE accepted certification body CB based on reports given by an IECEE
accepted test laboratory CBTL (see IECEE certification for PV via
www.iecee.org/pv/html/index.html) according to
o EN 61215 “Crystalline silicon terrestrial photovoltaic (PV) modules - Design
qualification and type approval (IEC 61215)” ;
o EN 61646 “Thin-film terrestrial photovoltaic (PV) modules - Design qualification and
type approval” (IEC 61646)
o EN 62108 “Concentrator photovoltaic (CPV) modules and assemblies – Design
qualification and type approval (IEC 62108)“ and
o EN 61730-1 “Photovoltaic (PV) module safety qualification - Part 1: Requirements for
construction” (IEC 61730)”
o EN 61730-2 “Photovoltaic (PV) module safety qualification - Requirements for
testing” (IEC 61730)”
o IEC 62688 “Concentrator photovoltaic (CPV) module and assembly safety
qualification” (after official publication as standard)
Consideration of temperature test results (stagnation temperature) within IEC test procedure
(important at least for covered and concentrating PVT’s)
Full EN 12975 test of the PVT Hybrid according to SK Scheme Rules by a SOLAR
KEYMARK-recognized test laboratory
Reference of IEC (or IECEE) certification within Test-Report, Solar KEYMARK Data Sheet,
and Solar KEYMARK certificate (similar to the solar thermal system certificate according to
EN 12976 with the reference to the collector certificate according to EN 12975).
Calculation of Power output thermal and electrical including interaction of thermal on
electrical performance according ScenoCalc (if applicable). If it is not applicable, it need to
be clearly stated, that the recent data sheet is only an interim solution until the calculation is
implemented in ScenoCalc. Furthermore, the electrical operation mode the figures for the
thermal energy prediction based on need to be stated.
SKN_N0208R0
For PVT Hybrids where the PV module has been modified after original manufacture to
operate in hybrid, such as through adhesive or mechanical bond between absorber and
module, the following requirements need to be fulfilled:
-
-
-
-
Full certification of the PV module accredited and IECEE accepted certification body CB
based on reports given by an IECEE accepted test laboratory CBTL (see IECEE certification
for PV via www.iecee.org/pv/html/index.html) according to
o EN 61215 “Crystalline silicon terrestrial photovoltaic (PV) modules - Design
qualification and type approval (IEC 61215)” ;
o EN 61646 “Thin-film terrestrial photovoltaic (PV) modules - Design qualification and
type approval” (IEC 61646)
o EN 62108 “Concentrator photovoltaic (CPV) modules and assemblies – Design
qualification and type approval (IEC 62108)“ and
o EN 61730-1 “Photovoltaic (PV) module safety qualification - Part 1: Requirements for
construction” (IEC 61730)”
o EN 61730-2 “Photovoltaic (PV) module safety qualification - Requirements for
testing” (IEC 61730)”
o IEC 62688 “Concentrator photovoltaic (CPV) module and assembly safety
qualification” (after official publication as standard)
Verification, that the assembly of the PVT did not adversely affect PV components and the
PV module safety and durability through evaluation based on the IEC 61215, 61646, 62108
and 61730 retest guidelines
o CTL decision sheet DSH0647A:2010 “Retest Guidelines for IEC 61215 and IEC
61646”
o CTL decision sheet DSH0770:2010 “Retest Guidelines for IEC 61730-1/-2”
o CTL decision sheet DSH0778:2010 “Retesting guideline for changes in CPV cell
package technology”
(by an accredited and IECEE accepted test laboratory CBTL for the above listed standards).
Full EN 12975-2 test of the PVT Hybrid according to SK Scheme Rules by a Solar
KEYMARK- recognized test laboratory
Reference of IEC certification within Solar KEYMARK-Report ,Data Sheet, and Solar
KEYMARK certificate (similar to the solar thermal system certificate according to EN 12976
with the reference to the collector certificate according to EN 12975)
Calculation of Power output thermal and electrical including interaction of thermal on
electrical performance according ScenoCalc (if applicable). If it is not applicable, it need to
be clearly stated, that the recent data sheet is only an interim solution until the calculation is
implemented in ScenoCalc. Furthermore, the electrical operation mode the figures for the
thermal energy prediction based on need to be stated.
Only a few Solar KEYMARK recognized testing laboratories are also accredited for IEC testing.
The verification of electrical safety or PV durability aspects shall only be performed by IECEE
accepted CBTL’s with scopes including the above mentioned IEC standards. SK certification
bodies shall only do the document examination, that all required certificates and verification
reports are available.
