You’re actually correct about the total amperage being less than four and a half, but this guy is more correct than you. At peak wattage, let’s assum that the panel produces 45 watts. Divide the Watts (or P in Ohm’s Law) by the voltage (E) and you get Amps (I), 3.75 in this case. It’s Ohm’s law. And it is called a law for a reason.

bullshit on the amp s those panels only generat one twentieth of an amp a piece
but if you add a convex fucus mirror then you will collect more light therefore collect more powerb just dont hook them to your nipples

Forgot to ask….I’m in the Northeast. I have a mobile home. I will have a vented box for the batteries. What temperatures should these be maintained between?

Dan, good videos. I will be getting this set up. I also am getting a wind turbine, for later installation. Can you show how and what controllers etc, are needed so the solar and wind turbine charge the same bank of batteries?

I’m trying to live more simpler … I try to think what do I use electricity for?
and learning to preserve and can food.

Not sure if there is a cause-effect relationship, but after using a cheap inverter to keep a laptop charged during a couple of huricanes a few years ago I found myself replacing the transformers. I suspect (and perhaps someone who knows more about this subject could comment here) that sine wave inverters are needed for this application.

It’s great to see people turning out portable power with these things. Keep It Up!

Dan,
This was finally the nuts and bolts basics of the core components that are required which I have not found explained on the net. I now understand what I need, and also how I’ll add up my voltage for my outdoor lighting to figure out how long my deep cell power would last daily. I think you did an excellent job explaining everything and appreciate it!

I am a Communications Technologies undergraduate and I found this video very informative.
In my small opinion I think solar technologies maybe the way to the future of domestic power supply.
The move from oil and gas supplied electricity is good.
To run a house I think you’ll need 12 or better 24 volt battery and a Pure Sine Wave Inverter.
They give you more of a similar output to the national grid its expensive I’m sure it’ll get cheaper.
Thanks for sharing very impressive.

The battery in the video is a 12 volt battery just like your car so yes it will trickle charge the battery. Yes it will also charge a laptop.

would it be feasible to use just one panel like this and set up a bunch of mirrors to direct the sunlight to the one panel, instead of just having a bunch of panels?
March 23rd, 2009 at 6:09 am
would this be sufficient to charge a laptop? or what about car battery trickle ?

Price is still high and their efficiency relatively low ( 10-15 % or so) - otherwise they would.
When they break the 25 % limit and cost say 1/10 of the present price, this market will explode big time, and houses will be built with them built into the roofs or the walls.
March 28th, 2009 at 3:21 pm
I dont get with solar power why people dont do the whole roof that will get sun instead of having just one panel,surely you would get at least 5 times the power??
March 30th, 2009 at 4:50 pm
srsly, when u said $250 i rewinded the vid to make sure i hear u correct
March 30th, 2009 at 8:00 pm
Does that system have a charge controller build in so that you don’t overcharge the battery? (And on the inverter side, so that you don’t overdrain the battery?)
April 1st, 2009 at 9:21 pm
What kind of power can we get out of a system with the panel hooked up to a Bendini motor? that’ll be interesting..
April 4th, 2009 at 5:29 pm
You would actually lose some energy in the process.

Connect a gen. to that with a light weight pully.See if you can get more electricity out than power you put in. Useing special oils to reduce friction can you get like 220v or more? Or perhaps adjusting gear size to get the most power from a generator connected to this solor power instead of a fan. Worth a shot.

Hi,
Yes it would. Check out this video I made in June:

dude heres a thought put your FRESNEL LENS
on the SOLAR PANEL
wouldent that give you more power?
April 13th, 2009 at 8:34 pm
awesome stuff man!!
April 17th, 2009 at 1:06 am
niceeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

its all great until the sun goes down or its clowdy.
