    High and welcome.
    The questions you ask, require some lengthy answers, which might be better answered by an in-person interview in your neighborhood.
    You can derive some answers from the data in my .sig. Other questions require a trip to my archives, which I'm not willing to do.

    ​What is the cost of your panels?
    About $1 / watt delivered, 2012

    How many panels do you have?
    20

    What type of inverter?
    Xantrex XW 6048

    What is the capacity of the inverter?
    6Kw

    Why did you purchase them?
    to obtain electricity

    How much energy do you save every month?
    I have no idea, I am off grid and only make installment payments on the gear

    What type of solar panels?
    Monocrystalline Silicon String

    What is the output during summer and winter?
    summer 15Kwh
    Winter 5 Kwh

    What government regulations do you have to follow?
    must follow building & electrical code

    Are there any future developments that you are planning?
    yes


    This is an exercise for learning how to ask the RIGHT questions to get useful answers

      Focusing on "panels" is silly. ( cost, quantity,). You should be asky what size is the system, how much did it cost.
      Solar doesn't save any energy, it makes it.
      You can save on your bill but off grid people like Mike will have a different calculation with no savings.
      Gov. Regipulatiobs are generally followed by the installer not the owner ( unless they are one and the same)


      What exactly is your " learning place"?

          12 module (I have one panel made up of 12 modules. your use of the word panel is not correct.)

          PV doesn't save any power it makes it. more efficient appliances save energy.
          My PV system makes about 4MWh annually

          home owners have few regulations to follow, they are primarily for installers. However I installed it myself so
          I had to follow all local building and electrical codes.
          NOTE that the equipment used has to also comply with other government regulations like UL listing, anti-islanding, etc.

          not really. I could put in more batteries, currently 200Ah at 48V.

              ​Pls I need the information for my major assessment.....
              $6729 - prepaid 20 year lease - different from purchase
              30 SunPower 230 panels; total nameplate capacity: 6.9 kW
              SunPower 7000m string inverter
              7 kW
              Reduce electric utility costs
              Averages ~ 1000 kWh per month.
              Worst month is December at ~ 700 kWh. Best month is May at ~ 1300 kWh
              Must be installed according to local building codes. Must also meet utility requirements.
              None unless you count installing bird spikes to keep birds from landing - and pooping - on the panels.

              For bonus points, you might suggest reasons why my best production month is May instead of say June. Good luck!

                What is the cost of your panels? The whole system cost $8000 including tax, fees, permits etc. I installed it myself and probably saved around $4000-$8000. My panel wattage total is 4000, and most systems around here seem to cost around $3.50 to $4.00 per watt for a fully-installed system. Dollars/watt is the measurement most often used here to describe a system cost. And "watt" here means panel nameplate wattage. Also, I got %30 of the 8000 back as a tax rebate, so the actual cost was around $5500. That incentive will end in a couple of years or so.

                How many panels do you have? 16 panels, but the important number for comparison with other systems is that it totals to 4000 watts of panel wattage.

                What type of inverter? Microinverters, one small inverter under each panel, Enphase M215

                What is the capacity of the inverter? Each one is (I think) 225 watts, for a total of 3600 watts.

                Why did you purchase them? To save money on the power bill

                How much energy do you save every month? Average throughout the year is about 500 Kilowatt hours per month. For me that's about $1200 per year.

                What type of solar panels? Renesola 250 watt polycrystalline, Renesola Virtus II JC250M-24-Bb

                What is the output during summer and winter? Not sure if you mean power (watts) or energy (watt hours). The peak power during the day is about 3200 watts in the winter and 3000 watts in the summer (hot panels put out less power). If you mean the total production for a day, it might be around 24 kilowatt hours summer, 14 kilowatt hours winter. That's because the day is shorter. On a cloudy day it might be 5 kilowatt hours.

                What government regulations do you have to follow? For me, which is typical, two sets, the local building codes for my city (which come from the National Electrical Code), and also the connection and metering agreement with the power company (not really government but just as important).

                Are there any future developments that you are planning? No, that's it.. If I ever get an electric car, I'll look at adding to the system, but if there are any rules or other conditions that make it a problem, I won't change it.
