Robin Said:

Solar Panel energy 1500 KW monthly?

I assume you mean 1500 KWH (Kilowatt Hours)

A good panel may produce about 100Watts. It will cover about 12SQ FT. Lets say you have a ranch style house that is 2000 SQ FT. That means if you covered your entire roof with panels, you could get about 165 panels on the roof(Not really, because you need room to get around them. Lets say practically you could get 100 panels on the roof. You could produce 100X100, or 10,000 Watts/hour (10 KW/HR)when the sun is at peak. Each hour you would produce 10 KW HR's. Lets say your area is perfect and the sun shines bright 10 hours a day, so You could potentially produce 100 KW HRS. There are losses envolved in the wiring, Battery Charger, Storage Batteries, and rectifier-controller. Maybe more realistically you could get 70 KW HRS per day. Maybe you could get 1500 KWH in about 21 days.

Each panel will cost about $500-$700. Panels alone will be over $50,000. The entire system installed about $100,000. This should cover your electric at least during sunny times. If you live outside of Arizona, lots of luck.

Still much cheaper to ude the grid.
