sopray ?? never heard of them and not much research reveals yet another Chinese pop up company , having a look at their specs They rings alarm bells , basically they a panel that is 1580x808x35 , they obviously flash test them under perfect lab conditions what ever output they get they sell them as.
So the same panel can be sold as a 150w or a 180W , not bad marketing really because they sell the reject panels as lower power ones without saying they were hoping for 180W but because of second rate materials they only achieved 150W.( in perfect conditions ).
Quality manufacturers like Suntech underrate their panels so it's not uncommon to see a 185W panel put out 195W , most other companies would sell the same panel as a 195W or 200W panel.
The new PVI-2000 Power One Aurora looks nice , but to soon to know how well they will perform , the slim line one with the bigger lcd display isn't a full outdoor model , I think that's why you mention colourbond roof .
If that price included well known quality panels then it would be quite acceptable.
