How many solar panels are needed to produce 30 amps AC.?

Answer 1

To answer this question I need to know what the amperage output is or watts and voltage for the type of solar panel you have.

If you are trying to get actual numbers, do not use the rated voltage output of the panel. That is how they get the maximum theoretical output. (that can not happen). You need to look at the source you are feeding for this voltage. A car battery, for example, is 13 VDC or so. (13.6 at full charge, 12 VDC if almost dead) You can then take the maximum current rating of the panel and determine that if not shorted, you will get about 75% of that current.

Let's assume you mean that you want 30 amps AC at 220VAC. That is 6600 watts. To get one hour of that amount of power would take roughly 8500 watts of solar panels at full sunlight. If you want that amount of power over a 24 hour period, the total panels would need to be roughly 10 times that amount, or 660,000 watts of panels. If you are buying 100 watt panels, you need 660 of them. This is the BEST case for that level of power. Your inverter will not produce energy at 100% either. We also ignore any battery loss or wiring issues. Heat is going to give you loss also, unless you have good wiring.
