orientation of roof is important
will not get much momey to sell to grid, it is all about not buying the energy.
Solar is okay but still not that great (20% efficient)
Batteries not worth the money yet, unless ya live in a area that regularly losses power
Try and do all high power usuage during sunlight hours, this is where you really save money
You can get a switch (not that cheap yet) to heat ya water when there is excess energy being produced by your installation
good thread to start
in the end there is really no-one that is not trying to make money and the real issue is cheap imports/quality (even if Tier 1) and business closing down.
