Hi Stan
Does seem expensive, Even if these were top of the range brands, which they aren’t.
The size of the system is good, and the products are fine, but yeah, worth some more quotes.
You can try the companies listed on our Solar Installers Central Coast page. They are just ones that I put in after doing a bit of research on the net, so no personal recommendations or anything, but should be a good start.
Cheers
Marty
