[QUOTE="Bob Smith, post: 539619, member: 35176"] I would first answer the same than Binky. go with the configuration that gives you the higher wattage. I mean configuration. eg if you can fit 10 * 500W panels = 5kWp but if you can fit 14 (because they are smaller and better cover your available area) *400W = 5.6kWp You should always try to use has many strings as possible. Even if generally string inverters comes with 2 string MPPT you can still be supplied with a 1 string inverter (or worst, the installer put all the panels on the same string. There are many youtube videos and posts here that explain all this but in a nutshell. The panels are in series on a string, so if you have a panel that fails or get a significant amount of shed compare to the others, then the output will be entirely affected There are ways to mitigate but I do not want to bombard you with a lot of info at that stage. So there is no reason why the 12 panels cannot go on two strings [/QUOTE]
