Frequently Asked Questions

Q: What is the main cause of power generation loss in solar power plants measured by DustVue 10?
A: Panel soiling caused by dust, pollen, and pollutants adhering to solar panels is the main cause.
Q: What is the estimated impact of soiling loss on solar panel output compared to other factors?
A: The output loss due to soiling has the second-largest impact on solar panels after the amount of sunlight.
Q: What are the common issues associated with the conventional two-panel comparison method?
A: The issues include difficulty in maintaining the clean-side panel, increased costs, sensor differences, and difficulty in maintaining long-term accuracy.
Q: How does the DustVue 10 protect its reference cell during measurement to minimize contamination?
A: It protects the reference cell with a cover and exposes it only for a short time during measurement using an internal shutter.
Q: What is the measurement accuracy of the DustVue 10, and how often does it require maintenance?
A: It can grasp the loss due to soiling with an accuracy of ±1% and requires maintenance about once every six months to a year.
