30 Watt Solar Panel

I have the charge controller. I just need to know what type of capacity I need to not waste any electricity generated by the panel.

I plan on using the generated energy each day so it will not be building up over several days or...

A regular car battery will probably be more than big enough. I doubt the one panel will even completely charge it in one day.

Ideal for remote locations, RVs, tractors, exterior lighting, boats and more, the Sunforce 30 Watt Folding Solar Panel conveniently folds in half ...

I have a 30 watt solar panel but I plan to expand. Can I go ahead and use a 300 Watt power inverter with the 30 watt panel? Will it work?

You sure can. All the inverter cares about is having enough voltage.

When the sun is going down, my 3000 watt inverters keep putting out voltage until the last minute. Diminishing with time of course.

I'm looking into solar panels for my house. But when I run the figures, it would take forever to pay itself off.

Example: 224 watt solar panel X 4.73 hours/day (peak sunlight hours where I'm located) X 30 days/month X 12...

No. It will never pay off.

Yes, panel will produce outside peak hours. However, your output is too high. While you will get some off peak power, you aren't considering that you won't get peak power because of panel orientation,...

I have four 12 volt batteries connected in series, and two 80 watt solar panels with a 12/24 volt 30 amp controller. What would be the most effective connections to charge the batteries?

Read the manual for your controller, which I assume is a charge controller. The better ones use a switch mode regulator so they operate over a wide range of input voltages and output voltages.

The manual should tell you what range...

i took some solar yard lights apart and put them together in a series. i was told if you take AMPS times VOLTS = WATTS. do you test it with ac volt or dc volts? I tested mine with dc volts and got 41 volts in good sun and had my meter set on Ma or...

A solar panel is a DC device, you so want DC voltage.


I don't think your panel is big enough: milliAmps are THOUSANDTHS of an amp, not hundredths. So 83 mA = 83/1000 = 0.083A, ie your power is 3.403 watts rather than 34.03...

So if I have installed a 12-Volt 400-Watt Wind Generator.

assuming the wind mill is running at normal speed

Does that mean I get 12 volts at 30 amps for a total of 400 watts coming from the wire? or is this over a...

"Does that mean I get 12 volts at 30 amps for a total of 400 watts coming from the wire?"

Yes.

"or is this over a certain period of time I get this amount of energy?"

Watts are equal to
