Power calculations

Segregated power consumptions into basic necessity, comforts and luxury (though I don't really have much for this category).

Basic:
Lighting+Acquarium = 20K Watts/week with peak usage at 3K Watts/day

Comfort:
TV+Comp+Geyser+Fridge = 32K Watts/week with peak usage at 7K Watts/day

Average power consumption = 52K Watts/week, 220K Watts/month

Actions items to replace with Natural solutions:
10KVA UPS (Battery + Invertor = Rs 15K)
Basic: 3K Watts/day (power required)
Approx cost of panel: Rs 20K / 1K Watt, Rs 60K / 3K Watt
Requires wiring scalable to 12K watts (72V, 8amps DC)

Comfort: 7K Watts/day (power required)
Install Solar water heater:
Savings: 60 units/month (Rs 312/month, 3744/year)
Cost: 17000/- (returns in 5 years)
Power generation required at 5K Watts/day
