i seen alot of …
i seen alot of invertors around but i find that the 24volt is rare and from your vid i found that they are more effecient as i thought i am looking heavly into Solar power as well as Solar Heating
to increase the …
to increase the voltage you divide the amps to increase amps you divide voltage the wattage stays the same amp X volt=watt i found this tidbit helpful to understand what hes saying
Dan Rojas… YOU …
Dan Rojas… YOU EFEN ROCK MAN… Honestly
Make more videos we love you.. if you make more videos people will remember your name your site and everything about you and go back to you for more info…. DUDE>>> FREE PUBLICITY XD
I like your video. …
I like your video.
I would like to point out that connecting the three
cells in series DOES NOT increase power.
In series:
P= i*v = (.5A)( 12v+12v+12v) = 18W
in parallel:
P=i*v = (1.5A)(12v) = 18W
You see you don’t increase power. You just
increase the current to your load. The power remains constant no matter what arrangement you have them in.
I am an Engineer, by the way.
good video though
Great videos. …
Great videos. Thanks!
If I hook them in …
If I hook them in series instead of paralell do you think I can run my inverter? The inverter is designed to run off of 12 volts so I risk blowing a fuse hooking up three 45 watt 12 volt panels in series. If I hook them in paralell I am back to point zero of my problem, not being able to even power an inverter. It basically works out to be a waste of my $240.00 dollars.
Hi Dan, your video …
Hi Dan, your video using the harbor freight 45 watt solar kit prompted me to buy one and I personally think it is . I could not run a 450 watt inverter or a 750 watt inverter off the supposed 4 amp 45 watt solar panel setup. Yeah it can run a couple of stupid lights in the daytime and trickle charge a battery but it ends up being a waste of money. I have two 6 volt golf cart batteries that work great with my inverters but it would take the HF unit days to charge them, what gives?
i love your vids

I know this is …
I know this is nitpicking, but do you have to say “amperage”? That isn’t a word. ‘Current’ is the word you’re looking for.
From an economical …
From an economical stand point the pay back on panels only needs to surpass depreciation and not orginal costs. You might be able to sell your panels after some time as they will still have real value like land, because they have production power.
Yeah since I wrote …
Yeah since I wrote this last comment I was thinking, and came to the conclusion itll be safer to start getting some panels installed, even though it isnt worth it now. If or when either have power outages, or so much instability. Ill be more ready for it.
Its not good to wait till the well runs dry.
thank you i needed …
thank you i needed some help and this helped me alot. thanks dude
If utility electric …
If utility electric rises double (and it will) then solar at it’s current price becomes “worth the money”.
Figure future inflation vs. the`falling price compounded by future demand pressure and -now- may be the BEST time to buy, not later.
EXCELLENT:-) Know …
EXCELLENT:-) Know what to look for to fix if I ever fine them at an auction.
Thank you for sharing.

love you videos …
love you videos brother good job I wish I could meet yea you probably have al ot of cool stuff I have some solar pannels from a goverment aution they work the voltage rectafier was fried on them so I replaced them and they are like new they are about 10 years old and still work like they did when I got them.
my panel is 20 volt …
my panel is 20 volt around 75 watt
Buy a small or …
Buy a small or large deep cycle battery, marine batter. If it needs to be portable buy a lead acid 12v 7Ah battery $19 ebay free shipping. This will flatten out the energy spikes. An inverter will turn on but will also cut off with a small load. What watt rating is your panel?
i have a solar …
i have a solar panel ,can i used direct to the inverter? and for the inverter can i plug some electrical divice? what kind of inverter do you sugest? please i have 20 + volt with mine panel. thank you

Having solar to …
Having solar to power you home is a great idea. It just isnt cost effective You wont be saving any money, at all. Unless the price of solar panels go down in price by atleast half, not worth the money. I incourage for people to buy, buy, buy So I will be able to afford them in maybe 5 years.
For 24 hour …
For 24 hour applications you would need roughly 1000 watts of panels to power 400 watts day and night. I would suggest a pure sine inverter with the lower number of 500 watts or more.
Batteries are measured in ah or amp hours 12V x 50 ah (marine battery deep cycle) 400 watts is 34 amps so each marine battery would last about 1 hour+ with a full charge.
So for night time use 8-12 batteries in parallel at 50ah.
the batteries discharge a bit and the inverter 10-15% waste.
how many 120 watt …
how many 120 watt panels ?? what size and type of inverter?? what size and brand charger and how many 12v batteries will i need …….to power 400watts ???? also how many hours of direct sunlight will they need to fully charge the batteries??
the beat part of …
the beat part of runing the solar panels in series is that you dont need to use heavey er guage wirew

yeah, I am burning out my inverter and batteries just running these inefficient 120 volt “energy saver lights”. I need 12 volt lighting and LED lighting fast!
