Hi @kpatel
These all look like quite good quotes really, and reasonably priced. Both Huawei and Fronius are very good inverters. I would probably lean toward the REC panels as my favourite here, but Longi also a decent option.
I think you’re main question here which we don’t have the info on is which company is the most well reviewed, and came across best in the sales process.
Perhaps this chapter in the solar guide will help:
