      grid connected solar systems are a kind of solar panels systems connected to public grid.through connecting to public grid, systems owners not only can save own electric bill,but also can get money back from electric company.
      base on above the reasons, many people wish to install grid-tie solar electric systems on their roof. however, with the reduce of government rebate,demand of systems are reducing,so the competition along suppliers is very sharp.
      when someone would like to purchase grid-tie solar systems, they perfer brand solar panles with higher cost, they think that those solar panels have better quality and long life.i don't think so,because solar panels production have many standards to follow,for example CE,IEC,TUV. if manufacturers can produce solar panels according to relate standards completely, i believe the quality of each module is the same as some brand panels. regarding guarantee, almost manufacturer can reach up to 90% power for 10 days,85% power for 25 years and at least 25 years life.
    on-grid inverters are another components in grid-tie solar systems, SMA is the most popular brand in the world,however some brand on-grid inverters from China are entering into world market,their quality can also reach to top level.
