Install Too Large Of A Solar Panel On A Micro Inverter And You'll Not Only Be Wasting Power, You'll Also Be Wasting Your Money.

240 Watts In 199 Watts Out ?

Don't Do Me Any Favors.....

For example several dealers are offering 240 Watt solar panels
coupled with a 190 Watt micro inverter. They use the number 190 because it has a maximum power rating of 190 watts. According to one micro inverter manufacturer, this inverter has a peak AC output rating of 199 Watt. Hmm....240 Watts in 199 Watts peak out ?

What happens to this solar panel's extra 41 Watts ? Your guess is as good as ours. Even if you were to consider the average PTC Watts rating of 214.5 taken from 11 panels on the California Energy Commission's website and you were to take this inverter's 95% CEC weighted efficiency rating, you would still have the potential of producing 203.77 Watts per solar panel.

That's a potential loss of 4.77 watts per panel or 142.1 watts per hour of exposure to peak sunshine.

In a world were solar panel manufacturers battle over even a fraction of a watt in improved performance, why in the world would you let some salesman talk you into throwing away 4.77 Watts of potential power per solar panel.

Wouldn't it make far more sense to connect your 240 Watt solar panel to a 240 Watt or larger inverter ?

But their coming out with a new larger 215 watt micro inverter with a maximum recommended solar panel input of 260 watts you say ?

Hmm ? 260 Watts in 215 Watts out ?

Must be one of those fuzzy math formulas that I heard
about when I was a kid in grade school.
