1500 watts per hour is a small amount of electricity consumption for an apartment in a very hot country.
Problems arise if neighbors write a statement to the police on you, then the police will already know what to look for, or they can then come with checks.
The most important thing is that no one should see this equipment.
1500w is small, you can still fit ~3000w in a THHN AWG 14 at 220V.
1500w is just around 1.5hp of AC a refrigerator and a few lights.
average heavy duty extension cords are rated at 2500w LOL.
So your AC compressor is running 24/7
all year long , your " few light bulbs" are on for 24/7
all year long , and your fridge compressor is running 24/7
all year long 
, and all this happening in a small apartment right ?
LOLSo your continuous power usage in that "small apartment" , just from the AC / Fridge / few light , is 1500watts 24/7
all year long, and using just this 3 things in that apartment, you paying around 133$ / months (
calculated with 12cents/kwh)
1500 watts 24/7 is not much for industrial usage that's for sure , but for a small apartment ?
That's 36kwh/day (4.32$) , 252kwh/week (30.24$) , 1080kwh/months (129.6$) ,
13104kwh/year (1572$)
Compare this usage with a world wide average ( especially for a small / reg size apartment ) , its not small at all , its actually more than the US typical household power consumption / year , and doubled what is the average in bigger European countries household power consumption / year .
From 2010 data :
In the
US typical household power consumption is about 11,700 kWh each year, in France it is 6,400 kWh, in the UK it is 4,600 kWh and in China around 1,300 kWh. The
global average electricity consumption for households with electricity was roughly
3,500 kWh in 2010.
From 2015 data :The
average U.S. household consumes about 11,000 kilowatt-hours (kWh) per year.However, electricity use in homes varies across regions of the United States and across housing types.
