You're not going make much with with that size system, you really need to get as many panels as you can. I'm guessing that as they are 405w panels it's not a FITS system so you can easily alter it without that complication. If you want advice ask in the other thread.
Solar panels and battery - any real world reccomendations?
They're available in 510w versions now too if you have 200mm to spare over the 455w panels. Same size as my rear wall panels which I got from Powerland (very pleased with their service), except mine are 525w.
