With several years experience in the solar industry, I can assist you to explain the solar system to the potential buyer regarding how the system works, the Net Energy Metering, grandfather period, warranty and any possible question they might have. 

There are steps you may consider when you sell your house with a solar system. 

1. Gather Solar System Information In Advance, such as signed solar agreement. 
2. Contact Solar Company for System Checking if needed. Make sure the solar system is working fine before transferring to a potential buyer. 
3. Inform Listing Agent. If your solar system has a monthly payment (not cash purchase), you should discuss with the listing agent how you would like to transfer the solar system. You may choose either to pay off system or have potential buyers assume the existing lease, PPA, or Loan program. 
4. Disclose Solar System During Escrow Process. As a seller, you should provide related solar information to the potential buyer. The related documents such as system warranty, signed agreement, solar company contact information, system monitoring and Net Energy Metering program.
