Solar panels installed on the roof
This is a difficult question because every home uses a different amount of electricity and each home also has different solar efficiency based on shade, the direction of your roof and pitch.
According to https://www.californiasolarstatistics.ca.gov/faq/#leads The average price per watt for a residential Solar system installed is $5.36 so if you had 275 watt panels the average price per panel would be $1,474.00 in California. However this price will very based on where you live in CA and what type of system you put in.
We are located in the San Bernardino mountains and in our area prices seem to be more like $4-$5 a Watt.
Well, it really depends on a number of factors. 1) what brand name or quality of solar panel do you intend on buying. 2) what level of effiency do you wish to have? Some panel produce much more electricity than others on the the same amount of sunlight, but will be more expensive. 3) are you going to try to diy? 4) Are there any remaining federal tax credits or rebates that are available?

This is really more dependent on the homes occupants actual monthly power usage than the size of the home. Different occupants will use differing amounts of power for the same home, so if you are looking to reduce your energy cost to zero one really needs to size the system on usage. This is tough to gauge in the case of the occupants not having any historical data for the building they are occupying. You can check with your utility company to get an annual breakdown on the amount of power you have consumed in your home, that is the basis on what the system size in Kilowatts should be for your particular situation.
If you are using 10 megawatts (10,000Kw) of power annually a typical system in New Hampshire that would produce 10 megawatts of power, given the arrays orientation to the sun is proper would be in the 7.5-8.0Kw output size. Depending on the actual panel output that could range from 24 (for 330watt panels) to 40 (for 200watt panels). Based in using 275watt panels, right now the sweet spot for panel size (best bang for your buck) for a 27 panel array, with the cost around $4.25 per watt that comes to $31,556. Depending on the utility and state there may be incentives to help defray some of this cost, along with the current 30% tax credit due to expire at the end of the year, your actual out of pocket cost could be reduced to half of the actual cost.
What size of house do you have? Are there shade issues? Are you looking for a 100% offset? How much power do you currently use? What direction does your roof face? Do you have roof space for panels?
These are all questions which would need to be considered prior to obtaining a quote…

You can get solar panels for $0 if you are willing to allow the excess energy to be owned by the installer.
Plus there are lots of government incentives.
Check with your local utility - usually they will be more than happy to help you get all of the latest up-to-date information & options available.
This is a difficult question to answer because every project is different. What is consistent across the board though is the fact that solar systems cost much less today than they did a couple of years ago. Your personalized answer depends on the size of your house, your energy consumption, your location, and the direction your roof is facing.
There is a 30% tax credit incentive (ITC) and more local government incentives depending on the city in which you are located. Feel free to reach out to us if you have any more questions, we’re happy to help!

Solar panels alone can range from $0.80 per Watt to $1.50 per Watt (Shop Solar Panels for Home | GoGreenSolar), but a total system cost (panels, inverter, racking, attachments) will range between $1.70 per Watt to over $3.00 per Watt with installation.
