| Insulation resistance | High, per standard |

Tie the final instalment to documents and net metering. If the installer is waiting on the utility for the meter, agree in writing what will be paid now and what later. Never hand over the final payment before you hold the warranty cards.
Within the first month, compare generation with the estimate, confirm exports in the bill and note any error messages. Report problems in writing. See solar installation in Raipur for what a good process looks like.
