Solar PV and Solar heating - Experimental resources

RISE has a first-rate set of resources for experimental evaluation of solar PV and solar heating.

Blue house (outdoor test)

The picture to the right shows some of the experimental test resources available - on the roof of the blue house - for outdoor testing of solar thermal and solar PV products. Test resources can be used for typing for certification and / or product development. 

 

 

 

 

 

 

Forskningsvillan (The Research villa)

Forskningsvillan
Forskningsvillan, the Research villa

Forskningsvillan, the Research villa, functions as a research center for future housing where new, innovative technologies and methods can be tested and evaluated in a controlled, yet real-life environment. Read more about Forskningsvillan (in Swedish).

 
Rigs and simulation tools for system solutions

Allows you to test different combinations of solar collectors, boilers / heat pumps and tanks, for example BIOSOL-Project (in Swedish).

 

CLIMATE CHAMBER FOR DURABILITY TESTS

Solar simulator

RISE solar simulator

The solar simulator can be used for solar thermal and solar PV products testing year round and has a capacity for modules with an area up to 15 m2.

Flash solar simulator

The flash solar simulator is the equipment that RISE uses for performance testing of solar cells in the lab in Borås. RISE can characterize solar cell modules of silicon and CIGS cells up to the size of 2.15 x 1.35 m. A characterization involves measurement of short circuit current (Isc), idle voltage (Voc), maximum power (Pmp), max power current (Impp), maximum power (Vmpp), cell efficiency, module efficiency and fill factor. Accredited measurements are carried out in accordance with IEC 60904-1.

Field measuring equipment for solar PV

The field measuring equipment for solar PV is used to determine the function of installed plants. In a field measurement, individual modules, strings or entire systems can be analyzed. The instrument measures current, voltage, and radiation and cell temperature.


The result is converted to STC and compared with nominal values. From the graphs we study the modules' fitness, including by seeing if there are serial losses, shunt losses or shadowing effects

Modulator for inverter test

The modulator for inverter testing markes it possible for us to test and evaluate the drive's ability to load solar panels optimally.

Watt meter with built-in measurement of harmonics

The watt meter (including built-in measurement of harmonics) is used for testing the power quality, which is a part of the evaluation of the inverters.

Monochromator

The monochromator gives us the spectral characterization of solar cells. In addition, spectral measurements are included in order to calculate spectral mismatches according to IEC 60904-7 (between the test cell and the reference), but it is also interesting for solar scientists to know the spectral division of quantum efficiency (ie, how much of the energy in the light at a certain wavelength as converted to power).

Source Measurement Unit (SMU)

The Source Measurement Unit (SMU) is used for measuring very small solar cells. This in practice means cells with less than 1 A and 1 V. These may be research cells that are often a few millimeters in width and length or indoor cells adapted to very low light, which also produces small currents.
