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.

250 Watts In 215 Watts Out ?

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

For example, several dealers are offering 250 Watt solar panels
coupled with a 215 Watt micro inverter. The manufacturer uses the number 215 in they're part number for a very good reason, and that reason is simple. Their micro inverter has a maximum power rating of 215 watts.

What happens to this solar panel's extra 35 Watts ? Your guess is as good as ours. Even if you were to consider an average PTC watts rating of 224.82 watts derived from 25 different 250 watt solar panels listed on the California Energy Commission's website, you would still have the potential losing 9.82 watts per solar panel because of this micro inverter's 215 watt maximum limit.

That's a potential loss of 9.82 watts per panel or 255.32 watts per hour of exposure to peak sunshine in a 26 panel micro inverter installation.

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 9.82 watts of potential power per solar panel ?

Wouldn't it make far more sense to connect your 250 watt solar panel to a 250 watt or larger inverter ?

Hmm ? 250 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.
