What You Need to Know
Originally I thought we could not have solar because our roof does not face south. But thanks to the more efficient SunPower panels we were able to get a west-facing system that still covers 80% of our usage! So the lesson is to be persistent and don't give up on trying to get solar.
Efficiency or Sustainability Improvements:
We added insulation to the attic first.
We want to reduce our ecological footprint, including our greenhouse gas contributions, getting as close to zero as we can!
Getting the right installers is key. Get a personal reference from somebody who's done it before and is satisfied with their installers.
Experience with Installer:
Independent Power Systems is great!
