Keep in mind if you go solar you need more than 2x the capacity so you can store it for when the sun is not up. The other option is to have one of those inverters that will provide 120v from the mains when the battery is depleted below a certain voltage.
Good point, i updated the solar panel requirements to 160watt as the inverter i have does not have switching to main power supplies.
What is your motivation for going solar? Have you worked out an estimate for the cost per kWh for solar electricity based on depreciating the capital outlay over, say, 10 years? How does it compare with mains pricing?
Good question! I live in california , usa the electricity costs here are around 13cents/kWh but PG&E runs this teir system(as they like to call it when i was talking to a pg & e representetive on the phone). The way their teir system works is that once you go over a specified limit you pay 14cents/kWh thats called the first tier. The second tier is 15cents/kWh and so on and so forth...
I live in a house full of power hungry people running multiple computers, one big screen tv, multiple smaller lcds, heating/cooling, refigerator, etc
When discussing my options with the representive on the phone they said that this house hold always hits the teir 1 and some of the time(every other month) hits tier 2. Dosent sound too profitable going through home electricity and its almost impossible to promise or guess profits projections from mining in the next ten years.
If projections is what will make you feel more confident i will be willing to take time and do the math but it really all is speculation beyond the next difficulty change so i cant promise my projections would be accurate over a period of ten years.
