Hot Spot Endurance Testing Chamber / BBA Steady Sun Simulator
HD-E905
This machine provides a near-natural light source within a specified area, featuring BBA-class light sources. It is primarily used for large-area PV module aging testing.
Specifications
Light Source
4 pieces, lamps imported from Germany (The light source is a core component and also a consumable)
Radiation Intensity
800–1200 W/m² (adjustable) (Single light source system can provide real-time signal output to the collector)
Wave Band
400–1200 nm
Spectral Matching Degree
Class B
Irradiation Inhomogeneity
Class B
Instabilities
Class A
Radiation Area
2.4 m × 1.4 m for 4 light sources to place 1 PV module
Light Source Hang System
Upper hang method: main frame uses high-strength, easily movable aluminum profile structure. Space between lamps is adjustable. After debugging, light source distance from PV module is approximately 1.5 m.
Light Method
Upper light, facilitating easy placement of PV modules
Irradiation Introduction
The sensor operates on the thermoelectric effect principle. Sensing components use winding plated multi-contact thermopiles with surfaces coated in a high-absorptivity black coating. Hot junctions are on the sensing surface, while cold nodes are located in the inner chamber. Temperature difference potential between cold and hot junctions produces an output signal proportional to solar irradiance within the linear range. A temperature compensation circuit minimizes temperature effects. Two-layer quartz glass covers, produced via precision optical cold process grinding, protect against environmental influences.
