The
top
five
suppliers
–
SMA
Solar,
Power-One,
Kaco
New
Energy,
Fronius
and
RefuSOL
–
all
held
onto
their
market
ranking
last
year.
However,
the
biggest
market
gainers
were
all
outside
the
top
10,
with
start-ups
like
Enphase
Energy,
SolarEdge,
Advanced
Energy
and
Emerson
all
notching
up
significant
gains
at
the
expense
of
the
industry
stalwarts.
And
the
competition
will
only
intensify
over
the
next
five
years
as
customers
buy
more
inverters
for
ever
lower
prices.
Inverter
shipments
are
expected
to
soar
23%
this
year
to
32GW,
but
total
revenues
will
grow
just
3%…
