How to Solve Solar Noise | NenPower
By leveraging innovative technologies such as active noise cancellation systems, establishing comprehensive planning guidelines for site selection, and ensuring effective
For the receive earth station, this once-a-day natural phenomenon of additional solar thermal noise is noticed as a source of interference, which causes signal degradation (interference causing lower link availability) or even daily outages (total signal loss) for small periods of time.
Any digital electronic equipment produces at least some noise. And nearly all equipment now used in PV systems is digital. The most common types of equipment to have problems are charge controllers, DC lights, and some modified sine wave inverters. Nearly all charge controllers send pulses instead of a steady voltage/current to the batteries.
Satellite-based communication is affected by sun interference which is caused by the sun passing directly behind a geostationary satellite as seen from a receiving earth station, see Figure 1.
In solar and DC systems you often have additional sources, such as switching power supplies, charge controllers, DC light ballasts, and inverters (especially modified sine wave types). There are dozens of digital devices in use nowadays, and digital - especially power circuits - emit more EMI than analog (AC).
