6 Frequently Asked Questions about “Hotspots in solar thermal power generation research”
How hot is a solar hotspot?
These hotspots register an approximate temperature of ∼50 °C, which starkly contrasts with the surrounding healthy solar cells that maintain a temperature near 25 °C. The FLIR i7 camera's ability to detect such fine thermal differences is instrumental in the assessment of PV module health and the effectiveness of our hotspot mitigation techniques.
What is the average hotspot temperature of a solar module?
The experimental results in Fig. 11 (a) show that one-third cell solar modules have average hotspot temperature at about 165.7 ℃ with some modules having hotspot temperature over 170℃. Some of these modules showed oiling, bubbles and burn marks on the backsheet, and failed the test criteria in IEC61215-2:2016.
Do high wattage solar modules increase hotspot risk?
The research demonstrates the effectiveness of studying hotspot risk with FEA method and how to contain the hotspot risk of high wattage solar modules by design optimization. With the rapid increase of solar module wattage from about 300 W to above 650 W, it is important to study the impact of high wattage on the hot spot risk.
What causes hotspots in solar cells?
The genesis of hotspots is often linked to physical defects, such as micro-cracks within the solar cells, as documented in the literature, , . Such defects intrinsically hinder thermal uniformity because they can create localized areas of increased resistance, which the mitigation circuit cannot physically rectify.
