Frequently Asked Questions
Does IES handle the paperwork for residential solar?
For residential solar, the company says it handles HOA applications, utility interconnection agreements, permit-authority final inspections and system commissioning.
Does IES's backup power supply start automatically during an outage?
It detects when main power is lost and switches on automatically; an automatic transfer switch feeds the property until utility power returns, whether the homeowner is present or away.
What can IES's energy audit tell a homeowner?
It can identify ways to reduce energy use and provide an on-the-spot estimate of energy costs after a solar upgrade.
