Hello Wrenches,
I had an inquiry concerning the effect of EMP on photovoltaic
systems. We are heading for a period of solar activity that likely
will produce this effect. According to a local AEP (American Electric
Power) representative, the utility is spending a lot of money to
counter this anticipated problem. Additionally, nuclear related
issues are moving back to the front burner.
It is clear that the pulse would damage an inverter, but possibly it
could be put in a Faraday cage. But a number of questions arise.
* Would the pulse damage the modules?
* Could the large currents and voltages induced by EMP damage the
conductors in the cells?
* Even if the inverters were surrounded by a Faraday cage, would
induced currents & voltages from the modules harm the inverters?
o Would series fuses and surge protectors be adequate
protection.
Has any research been done in this area? Does anyone know answers to
any of these questions?
Thanks,
Drake
I don't remember seeing much if any problems during previous 11 year
cycle solar maximums, really...
Being a ham radio guy, I look forward to solar max and more sunspots...
HF radio works WAY better during solar maximum !
