Engineering site visit
After you sign your solar contract, an engineer will come by your property to evaluate the electrical status of your home and ensure everything is compatible with your new energy system.
They will evaluate the condition of your roof and electrical panel to make sure they are both sound.
It should be noted that this engineer visit is different than a general site visit which is when an installer evaluates your property to consider system size, roof type, angle of roof, shading, etc. before any contract is signed.
