  • Astronergy Panels? installer installed wrong panels-wtf?

    Question: I just had a 3.22 Kw system installed. In my contract I was supposed to have 14 Canadian Solar 230W panels installed (CS6P-230P). However after the install I looked and they are actually Astronergy 235 Kw panels (CHSM6610P 235). This sort of concerns me. Which one is actually the better panel? I'm going to bring this to the installers attention, but if the Astronergy is actually a better panel I won't care as much, but if they are cheap knockoffs I'm going to be pissed. I checked my contract and it clearly states the panels and inverters to be installed.

    Does anyone know the company Astronergy? Thoughts?

    Thanks.

    Yes I know and use Astronergy modules
    You got an additional 80 watts due to 235w vs 230
    The Canadian Solar have a couple up sides to them
    The power tolerance is -0+5W on the CS as opposed to + - 3% on the Astronergy.
    The PTC ratings on the CS are the highest for the wattage of any manufacturer.


    The Astronergy Modules are a good module Manufactured by Chint
    The warranty is longer on the Astronergy and is insured by Deutche RE which is a large German insurance company.

    They are both Chinese modules comparable in quality

    As far as reductions in PTC and power tolerance goes this is for the most part made up by the increased wattage.

      Thanks Naptown,

        The quality is about the same on both.
        They are both tier 1 Chinese manufacturers so overall quality is good.
