Was happy with my quotes for 4kW system: SMA 4000TL with Suntech STP 250S 20/WD + Blackpearl.
The Suntech seemed to be very good regarding cost/output - but obviously their lack of availability rules them out.
Which 250W panel would be a good replacement, considering size of panel is not an issue (so I don't need the pricey Sanyo's) in respect of cost/output.
(Situation: big roof, SSE, 35 degree pitch, no shading)
Thanks in advance for your thoughts on the matter.
