    Q.Cell Q.Tron 435w panels w integrated microinverter? vs vsun or jinko + enphase iq8?

    is anyone familiar with this type of panel. I have a local solar company (estb 2016) giving a fairly decently priced quote for 15.48 kw output and 18,000 kwh annual usage ($40,248 overall cost about $2.25 per watt)

    They are also showing a Q.home combiner (model 80 G1)?, up to 64a input of solar and 144ac modules etc

    The panel spec im seeing shows low 25 year expected degradation of like 89%, in thoery i guess (Q.TRON BLK M-G2.H1+/AC 430 x 36 modules)

    The local provider says that q.cells is the most trusted panel in the usa with a massive plant outside atlanta, but will they be around in 10 years etc? They can cut costs by using a single source for both.

    But a combination panel, sounds like double trouble if issues?

    Also, vsun, apparently they wont be available next year in the usa due to china issues?

    My model comparable is (Eagle 54HM G6 440watt JKM440N-54HL4-B) and Vsun Vsun 440 watt vsun440n-108bmh-bb and Enphase IQ8SP-MC4-DS-0002-02 or iq8a

    $2.25 per watt is not bad.



    ... The local provider says that q.cells is the most trusted panel in the usa with a massive plant outside atlanta, but will they be around in 10 years etc?
    Your provider is a salesman. LIke all horse traders and used car salesmen that is his job.

    He is not an Electrical Engineer.

    Every year new systems are introduced and marketed.

    Which of them might be 'trusted' changes every quarter.

    I would want to meet their techs, ask them what degrees they have.

    A standard fly-by-night company will have a herd of self-trained or OJT techs, with zero knowledge of how it all works.



    ... But a combination panel, sounds like double trouble if issues?
    If they have a warehouse where they can test your panel, then it might be easy for them to troubleshoot the panel ten years from now. But in reality, once it is installed. Nobody will remove it to ship back to the factory for troubleshooting.

    You are right to be concerned.



    ... Also, vsun, apparently they wont be available next year in the usa due to china issues?
    Oh cool. I always like talking to folks with a reliable crystal ball. See if they can give you any stock market tips, since they know all about the future.

      Yeah there are some red flags here, they did quote using jinko 440 panels + iq8s of around 44,000$ usd for 18,500 production (15.5kw i think), 36 panels again, which still was about $4k less than anyone else.

      They were established in 2016, but have good local reviews and energysage reviews, so im unsure, unknown their level of knowledge as you said.

      I still feel like integrated could be trouble with the q cell idea.

      Other threads in other places outside of here seem to say the qcells are solid though.

      I did the math wrong, i think its the cost / the ouput power not kwhr produced, so for instance, they quoted jinkos + iq8x's, its $2.80/watt

        Stay with Qcells AC modules, but make sure the embedded microinverter is sized right and the branching is clean

          I ended up getting Hyundai 440 panels n 8x inverters from the same company. Or will be, contract signed etc

          40 panels 17.5kw output. First year production w aurora model 20000 kwhr(seems optimistic)
