then multiply kWh by cost per kWh to find cost.

so if this was a 60watt bulb..on 1 hour every day of the year…
60 watt x 1 hour x 365.25 days/year / 1,000 = 21.915 kWh

now if you pay $0.10/kWh now we do:
21.915 kWh x 0.10 = $2.19 / year

(100 watt bulb x 6 hrs/day x 30 days) x 6 bulbs / 1,000 = 108 kWh .. now I’m not sure what rs or 2.00/unit is for.. but take the 108 kWh and multiply it by how much your electric company charges you per kWh.

The other variable you will need to know is the maximum you consume at once. Say an A/C unit will draw 3,500 watts at a time, if that and your electric oven ( 3,000 watts ) turn on at the same time, that's a current draw of 6,500 watts at one time. So you would need enough solar panels to supply 6,500 watts at once ( 6,500 watts usage / 46 watt solar panel = 141.304347826 ), so you would need 142 solar panels that produce 46 watts.. which is ridiculous. So you need a way to store this power, when you aren't using it. To store the power you would need a charge controller and a battery bank. Well 6 kWh /day would be 182.625 kWh / month. I'll give you a little more just incase. So 7 kWh /day will give you 213.0625 kWh / month. ( 7 x 365.25 / 12 = 213.0625 )... Now a single 46 watt solar panel can produce ( 46 watt x 14 hrs of sunlight x 365.25 days a year / 12 months / 1,000 = 19.60175 kWh / month ) you need to get 213.0625 kWh just to be safe, so 213.0625 kWh needed / 19.60175 kWh per panel = 10.869565217.. so 10 - 11 solar panels would work fine for you. You can get some solar panels online that can produce more watts so you don't need as many. But sometimes a lot of smaller panels might be cheaper.

A solar panel supplier is offering me panels of 46 watts and 34 watts each. How many panels do I need to supply the consumption I have and be sure I will not run out of electricity at any time?

That's 8,500 watts? Well if that figure is correct, and it is on for 5 hours a day, that would be 8,500 x 5 = 42,500watt hours, which then you would convert this to KWH, 42,500 / 1,000 = 42.5KWH / day the device is in use.. at $0.10/KWH that would cost you, 42.5KWH x $0.10 = $4.25/day or $4.25 x 365.25 days = $1,552.31/year!
