  • Questions about Solar Installation (Orlando, FL - 11.6 kw)

    I trying to decide on solar and I have questions about costs and equipment. And while being technically mind, I know nothing useful about solar with regards to practical application. Below is the scenario.


    The price to install a 40 panel system system totaling 11.6 kw DC is $26,026. This 11.6 kw system installed on the southwest roof assuming very minimal shade will generate approximately on average 1300-1400 kWH per month depending on the time of year (summer or winter), which will offset approximately 80% (normally $200/month avg.) of the energy bill based on the past 12 months of energy usage data.
    The system consists of the following components:

    * REC solar TwinPeak 2 290 Watt panels (http://www.recgroup.com/sites/defaul..._rev_e_eng.pdf)
    * Power Optimizer P-300 DC (https://www.solaredge.com/us/products/power-optimizer#/) at each panel.
    * SolarEdge 10000 inverter (https://www.solaredge.com/sites/defa...-datasheet.pdf)

    Rendering showing the maximum amount of panels that will fit on the roof based on Helioscope software.

    + ~$67/panel SolarWorld's Panels SW300 (https://www.solarworld-usa.com/~/med...ior-9-1-17.pdf)
    + ~$67/panel Mission Solar Energy Panels 300W 60-cell Mono (http://www.missionsolar.com/wp-conte...PERC-60_v2.pdf)


    The increased price to install SolarWorld or Mission Solar panels would cost $28,694 (= 26,026 + (40 * $66.7))

    The whole complete solar package is eligible for a 30% Federal tax credit.

    The payment terms are as follows:
    25% deposit
    50% payment due upon ordering equipment before installation
    15% upon inspection with building department
    10% Duke Energy interconnection




    These are my questions:
    1. Price, how is it? Expensive? Cheap? Middle of the road?
    2. How are the panels compared to? REC vs SolarWorld vs Mission Energy. Are they three junk? Information regarding the specific modules listed would be great.
    3. How are the SolarEdge Power Optimizers?
    4. How is the SolarEdge inverter rated?
    5. Anyone have Duke Energy I know Duke has Net Metering in Florida and it is 12-months rolling - Is Duke is it a continuous rolling credit or is it a 12-month reset at an some anniversary date or calendar date?
    6. Anyone have Amica Insurance -- Does their typical home insurance include solar? Or is a Special provision needed/required?
    7. While this system does not provide 100% of the energy needed, but if it did and I never owe Duke any money, with Net Metering does Duke still charge the 'Customer Charge' ($8.76) or 'Asset Securitization Charge' ($4.00) per month?

    Let me know if any additional information is needed. I also wasn't sure if I should be posting this in multiple categories since some of the questions deals with equipment and there are category for that.

    UPDATE:

    I found some additional info after writing the above:
    w/r/t Duke's Net Metering, I did find some additional information: It looks like at the end of the calendar year they buy any credits at COG-1 tariff rate. From energysage.com it states, "The current rate for COG-1 is 6.310 cents/kWh". While, it isn't great, it's not terrible either.
