hello hello thanks for tuning in okay we are back at the harbor freight panels
this is going to be the one year review to see if these things have held up and if they're still
putting out the rated power they have been out in rain snow hail sleet they've fallen off of
the small house here the tiny house they've fallen off face down so they've been through a lot
and these are the two different kinds that they sell i do believe that this
is the older style one and that's the newer style one with the more lines in it but
no damage over a year out there's no fading nothing's going on like i said they've fallen
from about 15 feet face down onto some dirt nothing happened and it's about 12 noon
we got the sun is really bright up there and right now we are checking this panel here
the newer style one i believe like i said this is coming up on a year of already having them
and if you see here we got 80 watts coming in so it's still 80 percent efficient after a year
six amps for the peak
so 87 watts were to peak so almost 90 efficient still after a year it's
extremely good i'm gonna go ahead and jack the power consumption up and see what happens
we'll bring it down into the 12 volt range and then turn it off and see what it spikes
at because it is going through a pwm controller so it's not going to be exactly perfect
and as you see it's starting to go back up
say we're over 6 amps so it is producing actually more than what the manufacturer states
as far as amp-wise goes
so we're over 80 efficient
going on 83 it's phenomenal after a year of being out in the weather
consistently and all they were done is wipe them off that was it for the test and now we're in
the pwm charge mode and let it go for a few minutes and see if we can get over that 87.
okay i don't think it's going to get over 87 watts peak
which is 87 efficient which is still doing very good
and obviously if the battery was drained down a little more and there was some more load on
it there's variables and it's a lead acid battery it's not really good solid hookup
i just threw it together just to check them and we're getting like i said 87
almost 89 or 88 watts which is out of 100 watt panel that's that's really good so i'm gonna
go ahead and run it down a little bit more and go ahead and switch over to the secondary panel here
which again i have to check but i'm not sure if i'm not sure which one harbor freight still sells
but they're both about a year old okay we got this one hooked up under load now
and we're letting the voltage drop down and we'll go ahead and turn this off we've seen 5.82 peak
which was 75 watts peak we'll turn it off and see what we can get
i'm coming up on 76 watts
all right we're gonna let this one climb and then come back and see what the peaks were
all right as we can see this panel is also at least 80 percent efficient after a year
82.5 was the watts peak and we're still under a load so we'll take it off and see what happens
and there we are almost 85
watts 85.6 and the other one was 87. so still doing way better than expected
even with degradation being out in the elements for an entire year all types of weather
so definitely think these harbor freight panels are a steal of a deal the price did go up though
so if you can find them um usually they go on sale for about 89 bucks for 89 bucks with the legs
you can't beat it the only thing is the sae connectors do not like them you can get them
in mc4 adapter or you can just cut them here and add your own mc4s but as you can see these
panels are definitely a good buy hope this helps thanks for watching please subscribe
