Measuring Panel Output. How is it done?

[Mike90250]

.... Untill it got the full sun I was reading 20 to 60 milliamps, then climbed rapidly once the sun came around and faced the window. ....

If this is being measured indoors, through a window, you will never see full power.

Unfortunately for the USA it would cost trillions of dollars to convert everything as its not only manufacturing ,just about everything have to change sizes and measurements,and all laws and specifications would have to be changed,
And as the USA is not exactly flush with funds ,its going to remain on the back burner for a very long time..in my opinion to about 3 days just short of forever.
But there will over time be some things that will change as now you buy just about everything electrical from China. And all the components are metric and the nuts,bolts,screws. Same goes for all imported vehicles..


Look at it this way. there are about 6.5 billion people in the world ,less than 400 million of them are using the non metric system , But even that is not totally correct as I have said in many instances that 400 million are having to use the metric system .

Let the Russians play with useless numbers ????
more than 90% of the worlds population use the metric system.. Reason SIMPLICITY..
GEE Crumb you had better depart from the US As the money system there is METRIC using "russian useless numbers)

Last I knew I think those powerhouses, Rwanda & Brundi, along with the US were the holdouts against metric.

Metric is only simpler and easier in every way - besides you don't want your space ship to go smack into a rock because someone didn't know how to make a conversion do you?

Where would we be without Crumb to give us a funny post to read each day..??

Russ you can get 5000w panels at all solar shops.And very cheaply . you just working out the figures wrong.
It goes like this... You simply purchase a 3.5w panel OK ?you still with me??/ its not difficult .. then place it facing the sun for 4 hrs a day ..OK? you not getting lost with the maths? then after 365days you will have 5000 whrs.. See there you are a 5000w panel...

If I get more than 5000 whrs do I have to give them back?

The metric system is backwards, dangerous, arbitrary and should be outlawed completely in America.
Let the Russians play with useless numbers. I don't care about the metric system so I used feet, as it should be.

A true mental midget!

Something like that. Send him to the Bikini Islands, give him the title of Prince to succeed the King Muamer Gaddafi Duck.

I rest my case your honor. Convict this man of stupidity.

than please explain to me why 99% of all american cars made today use metric just about everything and other than the British and I think they converted and the US everywhere else in the world is metric. And as a bonus it is easier to use.

Next up: I borrowed a good meter today.

Panel is making slightly more than spec. 3.87 amps at 14.7V.

Sunking stated it correctly -

Most people in the world (except for backwards a few places that still use the English system) would realize that m2 mean meter square.

Something like 10.37 square feet in one square meter.

When will the idiot politicians have enough nerve to force the change to metric? The old system is worse than silly and anyone doing international work HAS to use metric.

No one makes a 5000 watt panel for sale.

At least they make 5000W panels. I never heard of an M2 but I assume it's military? Gotta be big ones. Have fun with those man! Serious hardware right there.

Do not install fuses on the negative side. It will serve no purpose!
