Energy Self-reliance

SDA works with you and your architect
SDA will collaborate with you and your architect on renewable energy systems engineering for your new home.
SDA collaborates with you to create an elegant, simple-to-maintain home environment that reflects your unique needs:
  • We provide complete design/engineering services, or can partner with your local architect to design state of the art renewable-energy solutions for your new home

  • We'll assist you with land selection and site orientation

  • Our grid-interactive systems export surplus electricity to the local utility network - battery back-up is available when the utility fails

  • We also design grid-independent systems - such as those on remote islands - that use a bank of batteries for on-site electrical storage.
