You’ve done great so far. When you last spoke with your Sunrun solar installer, you were pumping your fist in the air. It’s time for your installation!
Sure enough, the solar installation crew arrives at your home in a couple of days, looking fresh and ready to get to work. Your crew’s arrival will have been planned with you beforehand to give you ample preparation time, so you give them the go ahead to step up on the roof.
Overall your solar installation should take 2-4 days, depending on weather and the size of the system. The first thing you will see them do is install the racking. Racking is attached directly to the eaves of your roof to ensure that your panels will not come loose. Each point of connection is then waterproofed to prevent any leaks from occurring do to installation.
On the following day your installation crew will arrive ready to install the solar panels themselves. Your panels will be hoisted onto the roof by a pulley system and attached to the racking that was installed earlier. Once your panels are fully installed, it will be time to wire the system and installed the Sunrun meter and inverter.
Your inverter is an integral part of your solar system. It converts the power your solar system generates (direct current power) into power that can be used by your home (alternating current power).
Once your solar installation is complete, your installer will send documentation to your electric utility requesting interconnection. Interconnection is required because your solar system will be connected with your utility. How the connection works will be explained in our next post Step 5: Connecting with your utility.
