75 Watt Solar Panel

I have 640ha of battery storage and 4 x 75 watt solar panels to a 24 volt system, I have heard that the smaller wind generators are a waste of money.

This is the home theater electronics forum, where the discussion is centered around technical home theater system and TV operational and electronics problems. What part of "home theater electronics" sounds to you like solar panels and/or...

You can obtain everything in life with one of 2 things or a combination of both. Time and Money. If you have the time you can find free solar ...

Harbor Freight sells a 75 watt solar panel, a surge power inverter, and deep charge batteries. But no one there can tell me how to put it all together. I want the end output to be a simple power bar that I can plug my devices into. I live in an...

i wouldn't.
- harbor freight isn't known for the best quality stuff.
- 75 watts assumes roof mounting, at 90 degrees to the sun, on a bright day. you're going to get considerably less. and only when the sun is highest in the...

am having a 75 watts siemens solar panel and is giving me 12.89volts during bright light, i wanted to know can this be used to charge 100Am/hr battery?

mmmm 12.89 volts is a bit low for charging a standard lead-acid battery (and you want to use a deep-cycle/rv battery for this, not just a plain car battery); ideally, you want 13.5-14.0 volts. this slight overage is needed to break the internal...

golf cart batteries. Should this be enough power to run lights, water pump, etc, with conservative use?

no

I have made a 15v dc 52watt solar panel and I going to be trying to charger 4 12v dc 55ah batteries. I get about 6 hours of sun on my panel. Spec below, is that a big enough panel to charge the batteries???

I have 30 3x6 solar...

>will a 15v 52watt solar panel charge four 12c dv 55ah batteries?

Eventually. But the panel seems way undersized. Some rough calculations assuming you live in a nice sunny desert:

Under ideal conditions the mppt...

Okay, I think I understand what I'm doing, but I want to set up some solar panels on the roof of my garage, the building that gets the most sun, and I want to make sure all my math is correct in determining number of megawatts per year. However,...

For comparison, 36 of these make a normal 12V x 50W panel. Note they are not tabbed. This means you have to find a way to connect them yourself. The tabs are probably spot welded on by the suppliers. A supplier below has kits of these with tabs,...
