The 3 quotes I have for the same building range from a capacity of 1.92kWp to 3.36 kWP, all using the same plans to quote........ and bizarrely the quote in the middle uses all 3 roofs rather than just 2. The price range is £10k to £13600 with the largest system at £10k (!) but only using a single inverter. All the quotes use Sanyo panels due to the restricted space, using 240, 245 and 250 W panels.
Cheers
Difficult to evaluate the systems without knowing the details. If there is a single inverter being used then it must have a dual MPP tracker like the SB4000TL. If not then the system is very poorly designed.
