Hi Sean
Looks like the main difference here are in the panels. I would think lean toward Q Cells, or Trina, or Canadian. Which doesn’t really narrow it down.
Really what it would come down to with such similar quotes is the company that you are buying from. It’s the most important thing. Scrutinise their reviews and I’m sure you’ll be able to differentiate.
Here’s the relevant chapter in our Guide to Buying Solar, with the types of questions that you can ask each company to distinguish between them.
