Why Can’t I Use My Solar Panels Immediately After Installation?
Homeowners excited about installing solar panels are often surprised to learn they have to wait before turning them on and using their new system. What happens between solar installation and “going live”? The interconnection process explained by our Central Washington solar installers ensures you know what to expect throughout the solar energy system installation process.
When can I turn on my solar panels?
It takes 4-7 weeks on average to obtain permission to operate (PTO), including:
· City and county permit and electrical inspections - 1-2 weeks
· Utility inspections and PTO approval - 2-5 weeks, depending on provider
What Happens Between Solar Installation and "Going Live" — The Interconnection Process Explained
Solar panel installation in Central Washington takes just a few days. However, you cannot legally operate your system until the completion of these important steps:
Local building and electrical inspections
A city or county inspector must verify the proper installation, permitting, and code compliance of solar panels, wiring, and inverter and disconnect switches.
Utility inspection
After passing the above inspections, our solar installers will submit utility interconnection review documents to your local electric provider, who will verify electric meter compatibility and confirm that your system can be safely connected to the grid.
Solar permission to operate (PTO) approval
After performing the inspection and any necessary meter work, your utility company will issue a PTO certification – your green light to begin using your solar energy system.
How long does it take to get permission to operate for solar from start to finish? City and county permit and electrical inspections usually take a week but may take up to two weeks due to backlogs. Utility inspections and PTO approval typically take 2-4 weeks for those in public utility districts (PUDs), and 3-5 weeks for Pacific Power/PacifiCorp customers. If you need a new electric meter or other equipment upgrades, additional time may be needed.
What to Do While Waiting for Solar PTO in Central Washington
Though wait times may feel long, the PTO process ensures your safety and the safety of local utility workers. During this time, we recommend registering and learning to use your solar monitoring app so that you’re ready to track solar energy production and usage as soon as you receive approval to begin producing solar power. Our solar panel installers can also take this time to explain how to operate your battery backup system and what to expect on your first utility bill regarding solar production and net metering credits.
