Solar PV Inteference ?

["Tracey Gardner" <tracey.gardner@xxxxxxxxxxxx>]

I'd be interested to hear what level of interference is generated/radiated
by these inverters?
I'd expect to be getting some degree of interference within the dwelling on
the long and medium wave broadcast bands?
Has anybody checked?

Many thanks

Tracey

Stewart,

I looked at the micro inverters but the cost (for me) was prohibitive. 21
panels each with its own micro inverter worked out around £4000 , the
cost
of a single 3 string, transformerless SMA inverter was more like
£1600.  I
was looking at the SolarPV as an investment so the bottom line was not how
efficient things would be but how much profit they would earn me over 25
years. I don't believe the micro inverters could ever earn me back enough
in
the 25 year period to pay for the cost differential. Of course if I was
only
having a few panels then it may work out differentially, e.g a 1.2Kwh array
of 240W panels would only need 5 micro inverters so may well even have a
smaller capital cost than buying a single central inverter.
