Water Wall Design How Much Would It Cost To Have New Insulation, Solar Panels And Water Heater?

How much would it cost to have new insulation, solar panels and water heater? - water wall design

I'm in a class of environmental design and conduct research on a renovation project includes a new green insulation (roof and wall), solar panels and water heaters for the renovation of a house of 2,000 square meters of 4 people living there. I need the cost of material and labor costs per unit. To say that I have a house in Southern California in the reconstruction.

And yes, I know something called Google, but it does not help much. We hope you can!
