Many of these types of companies do use SIPs or a similar highly insulated panel. 

Over the time that we owned it, we painted the entire interior, put new carpet on the bottom floor, replaced the entire kitchen, new electrical panel, put in new light fixtures in bedrooms and kitchen and glazed the tubs white.

Dear Everyone,I am planning to put Solar panels for a rental house in San Jose, California.

Since I have already had the ADU built, do i need a separate permit to install a panel?

The main fuse/breaker panel has probably been replaced since the house was built, but don't assume that the wiring has been replaced just because the panel is new. 

Again all stud-framing completed throughout, a finished basement, nd all electrical is roughed in, including an upgrade to new 200 amp panel. asking only 199k.so-called 3 cash buyers stood me up, this weekend made me look crazy.trying to get quality buyers and advice on working out the details, what would any knowledgeable member do if these were your deals?

What is the general consensus on adding solar panels?

I'm also looking at a larger home in East Warren as a possibility which has a few nice features (basement, deck, over 1/2 acre, solar panels, extra bedroom), but the higher price is a concern if I can't get tenants....Thanks for the feedback!
