I'm planning on using solar power to supply electricity to a 12x24' building. This building will be located near our main house, but will have no connections to the house, electrical or otherwise. It won't be connected to our utility's power grid, so there aren't considerations for tying it in.
I've done as accurate an estimate as I can, and figure I'll have a peak load of 2524 watts. I plugged some data in to a solar contractor's system calculator and it gave me this info, based on our location in central Arkansas:
- kWh per month: 288 kWh
- Sun hours: 3.76 hours/day
- System size: 3.06 kW
- Wh per day: 9590
I'm looking for some help making sense of those numbers. (I have an EE degree, so I understand electricity and electronics, but some of the numbers related to solar power are foreign to me.) For example, I'm looking at a system that is an "800W 24V solar panel off grid system kit with 8 100W mono solar panels, a 1500W 24V-110V Inverter, 200Ah Battery, and 60A PWM charge controller".
Will that system power my building based on the needs I listed? Does the output of the inverter (1500W in this case) need to be greater than my projected peak load of 2524W? It seems to me it would need to be, but I'm new at this.
