It's not watts used, it's kilowatt hours. So 1800 watts is everything running? You have to figure out the wattage of every appliance and how many hours it's running. That's your kWh. Then add those all together and multiply by the days in the month. Sounds like maybe you forgot to multiply by the days (30)? ...idk and I think your kWh is closer to 20 cents if I read correctly.
I could be wrong but this is why I post questions like this. Im not a math wizard but combined with a guy like me that doesn't understand electrical anything. Im in a foreign country. As long as my bill stays the same im happy.
Thats why im tossing it around to start now or wait a few weeks. That way I could get them outside ans save me thereOnce you know the kWh price you calculate the cost of each piece of equipment one by one.
Light - 200w × 18hr = 3600w ÷ 1000 = 3.6 kWh per day. 3.6 × 30 (days) = 108 kWh per month. 108 × $.24 = $26 a month.
Fan - 40w × 24hr = 960w ÷ 1000 = .96 kwh per day. .96 × 30 = 28.8 kwh per month. 28.8 × $.24 = $7 a month.
Do that for every piece of equipment.
Then figure out what you're going to say to the wife when the first bill comes.
You don't have to be a math wizard. That's why other good folks on the farm are here and happy to help. If you read back what I just posted it might be a good starting point to figure it out. If not DM me and we could go line by line.
LOL, dont forget about the human co2 output!A little 100w wall plug heater like that will keep a tent with radiant heat reflectors warm if you're not constantly unzipping it. Your air exchange is what will knock down it's effeciency. Or, if you want to sit in your tent for a prolonged period, humans put out 600 btu's per hour and every breath you take is about 20k ppm by volume.
How would your bill stay the same if you're adding appliances? Now you sound like you're trying to hide this from your mom!
Meaning from month to month. I honestly dont look at my bill if it stays the sameHow would your bill stay the same if you're adding appliances? Now you sound like you're trying to hide this from your mom!
Good luck with that. I'd rather take my chances with the wife lol
when it changes significantly enough i do. Lol
With a $.24 kwh price, your bill will go up $15 per month per 100w of light.Meaning from month to month. I honestly dont look at my bill if it stays the same
Wow. In that case, I'd be tempted to say "Screw you!" and disconnect from the grid and live off your solar!
We have a bank of batteries, eight, in the basement for when the power goes out. They will power the well pump, boiler(furnace), fridge and freezer. But don't even think of making toast.

They are deep discharge Trojan, 100 pounds each and over $100 each and have to be replaced occasionally.
The math sucks and we'll never recoup the cost of original equipment and batteries, but it was a life long dream for hubby, can't put a price tag on that.
