MICRO INVERTER PROBLEMS
6 Reasons Why You Probably Won't Want A Lower
Efficiency Micro Inverter
System On Your Roof.
Micro inverters offer a lower efficiency rating than
other higher performance inverters that are
available on today's market. A lower efficiency
rating will mean a smaller rebate in many states and
less energy harvested over the life of your system
which will lead to a slower payback.
Micro Inverters Can Waste
Power: One of the most popular
micro inverters that's being installed in today's
market only has a maximum power output rating of
215 watts while
consumers are installing solar panels of up to 260
watts. 260 watts in and 215 watts out ?
That's a difference of 45 watts ! And remember most
solar panels on the market today have a positive
tolerance rating. So your solar panel is actually
rated to produce more power that its name plate
But even if you were
to consider a more conservative PTC rating of 232
watts for a typical 260 watt solar panel, you're
still wasting 17 watts per panel. Combine 17 watts
of wasted power with the lower efficiency rating
mentioned above, over the life of your systems and
that's a lot of power and money down the drain.
Micro Inverters Run Hotter:
Again, because micro inverters offer a lower
efficiency rating, more of the energy that your
solar panels are producing is being wasted as heat.
More heat, especially underneath your solar panels
which reduces air flow on your already hot roof can
lead to premature micro inverter component failure.
Since micro inverter
manufacturer warranties typically do not pay
for the labor to remove and re-install micro
inverters, once your contractor's 5 to 10 year labor
warranty expires, you'll probably be left with an
expensive service charge to remove and re-install
dozens of micro inverters and the solar panels that
hinders their access as your system ages.
Many, Many More Points For
Potential Failure: Micro inverters are
simply miniaturized version of full sized inverters
with many of the same components. Any engineer will
tell you that the more components in a system, the
higher the risk of system failure.
With component counts
of well over one hundred in many micro inverter
designs, this means that the typical micro inverter
system will involve components counts that run into
All inverters will
fail at some time. Whether it's component wear or
a hard failure, the result is the same. After the
contractor's 5-10 year labor warranty has expired,
the consumer will have to pay up to $400.00 to
$500.00 per service call to remove all those solar
panels in order to gain access to that one micro
inverter that has failed. And you'll have to pay
that every time each micro inverter fails for the
life of the system.
A Micro Inverter System Costs
More: Take the average price of $171.00
for that popular 215 watt micro inverter that you
might be considering and you'll find that you'll be
paying about 79 cents per watt. Compare that price
to an average price of 50 cents per watt for a
string inverter and you get the picture.
Only that's not the
whole picture. 79 cents per watt is just the cost of
the micro inverter. To that you'll have to add about
$29.00 per each micro inverter for a drop
cable. And another $68.00 for an installation kit.
And about $20.00 for each branch terminator. Oh, and
don't forget an extra $526.00 on average for an
Internet portal, that is if you want to do any
monitoring of your solar panels over the Internet.
Micro Inverters Add
Additional Heat To Your Solar Panels:
Solar Panels generate power from light not heat. In
fact the hotter it is the poorer a solar panel will
perform. Your solar system will actually produce
more power on a cold winter day in full sunshine.
Solar panel manufacturers refer to this as
the Temperature Coefficient of Power Max or Pmax.
Typically for every degree over 25 degrees C (77
degrees Fahrenheit) in cell temperature, power in
watts will drop by approximately -.45 % or nearly
one half percent.
So for example, a 250
watt solar panel may lose up to 11.25 watts of power
when cell temperature reaches 87 degrees Fahrenheit.
The problem is that
due to a micro inverter's lower efficiency rating,
they tend to waste power in the form of heat.
Because micro inverters are mounted
underneath your solar panels while sitting close to your
hot roof, heat generated by the micro inverter
becomes trapped underneath the solar panel, raising
its temperature and causing performance degradation
and may even affect the life expectancy of your
solar panel in hotter climates.
It's already hot
enough as it is on your roof underneath your solar
panels. The last thing you want to consider doing is
adding more heat by installing inefficient micro inverters.
If you have any doubts
that micro inverters can produce a significant
amount of heat, simply read the warning concerning
the potential for burns when handling a micro
inverter that's included in that popular micro
inverter's installation manual where it states that
their micro inverter can reach a temperature of 176
Removing and replacing
a multiple solar panels in order to remove and replace one or two
failed micro inverters can quickly turn into an expensive
proposition. Now imagine having to go though this several times a year
as your micro inverter system ages.
