Claims
- 1. A failure detecting method of detecting a failure in a solar cell module, which comprises detecting a temperature of a bypass diode in a solar cell module from an exterior of the solar cell module, and detecting a presence or absence of a failure of the solar cell module based on a result of the temperature detection.
- 2. A failure detecting method according to claim 1, wherein the detection of the presence or absence of the failure in the solar cell module is executed by mutual comparison of results of the temperature detection on each bypass diode.
- 3. A failure detecting method according to claim 1, wherein the temperature detection is executed by a temperature detection means of non-contact type.
- 4. A failure detecting method according to claim 1, wherein the temperature detection is executed by a temperature detection means of contact type.
- 5. A failure detecting method according to claim 1, wherein the solar cell module comprises, in a vicinity of the bypass diode, means for preventing temperature rise resulting from a cause other than a current.
- 6. A failure detecting apparatus for detecting a failure in a solar cell module, comprising a temperature detection means for detecting a temperature of a bypass diode in a solar cell module from an exterior of the solar cell module.
- 7. A failure detecting apparatus according to claim 6, further comprising means for detecting a presence or absence of a failure in the solar cell module by mutual comparison of results of temperature detection on each bypass diode.
- 8. A failure detecting apparatus according to claim 6, wherein the temperature detection means is of non-contact type.
- 9. A failure detecting apparatus according to claim 6, wherein the temperature detection means is of contact type.
- 10. A solar cell module comprising a temperature detection means provided therein for detecting a temperature of a bypass diode in the solar cell module and a temperature of an internal portion of the solar cell module other than the bypass diode.
- 11. A solar cell module according to claim 10, wherein the temperature detection means is means for simultaneously detecting the temperature of the bypass diode in the solar cell module and the temperature of the internal portion of the solar cell module other than the bypass diode.
- 12. A solar cell module according to claim 10, wherein the temperature detection means is a visual temperature detection means.
- 13. A solar cell module according to claim 12, wherein the color changing member is means for showing a reversible color change in response to a temperature change.
- 14. A solar cell module according to claim 10, wherein the temperature detection means is a color changing member for showing a color change in response to a temperature change.
