The Process of SunPower Installation
SunPower presents an inclusive yet straightforward approach to installation. Numerous tasks are conducted by partners within SunPower’s extensive network of certified solar contractors. Here's what you can expect once you ask SunPower for a no-obligation quote:
Initial Consultation: A representative from SunPower will arrange a cost-free virtual consultation with homeowners. This session serves as a platform for you to raise any inquiries and understand the design of the system. Should your home be deemed suitable, the company will generate a detailed proposal outlining the design of your system, an estimated cost, and how it aligns with your energy objectives and end goals.
Permit Acquisition: SunPower takes charge of completing all the necessary paperwork and secures permits and approvals mandated by your local municipality and utility company. The duration of this process can vary, and in some instances, may extend to a few weeks, subject to your county’s regulations.
System Installation: Collaborating with SunPower, you will decide on an installation date that works best for you. The installations are typically executed by one of its certified partners, often completed within a day. However, more intricate systems may require additional time.
Final Verification: Prior to receiving the Permission to Operate (PTO), your system must undergo a final inspection, which needs to be carried out by both your local municipality and utility company. SunPower organizes these inspections on your behalf and will keep you updated. Once the inspections are cleared, you are free to activate your system and commence your savings journey.
