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:

Marty, Thank you very much for your response, I really appreciate it. See below who the company’s are. They all generally have good reviews and a couple of them have hundreds of them. My next step now is to visit each of their place of business to get a better understanding of what they are about and also ask more questions I may have. I actually went today to see one of them today with my wife and they actually came across as very good I.e not pushy, explaining the products etc. I think it helps to personally meet them to basically to get that positive feeling. Anyway below are the companies. Do let me know if you have anything to say (2 came via solarquotes)
Company A is CLEAN NRG SOLAR
Company B is PERTH SOLAR WAREHOUSE
Company C is EMPOWER SOLAR
Company D is FORMULA SUN

Kind Regards
