requirements, restrictions, and customer needs. Then review the schedule for
when the project is handed off to engineering, purchasing, staging, and
installation.
The project should then be turned over to a project manager and scheduled.
Then contact your state’s Energy Commission incentive program guide and use
the customer’s past electric bills to conduct an energy audit. There are several
other preparation steps you need to take before installing a PV system:
Review criteria such as financial resources, cost savings, and mounting space
when choosing the PV system size.
Go through all factory-designed PV system packages with the customer’s
desired features.
Compare different PV system products, warranties, and installation
guidelines.
Submit for permitting review, and determine when the permit will be ready
to allow time for comments or changes.
Order the equipment needed for the job; remember to choose PV products
and systems that meet local incentive program standards.
Schedule the materials for drop shipment that can be sent directly to the site.
Complete the pre-installation walkthrough with the customer or
customer representative.
Review the project with the installers, assign tasks, review safety issues, and
discuss the quality assurance process.
Remember to instruct the installers to clean up the site daily.
Brief the customers, and tell them what the next step is. There should be
no surprises!
Schedule inspections with the authority having jurisdiction or AHJ (the
local government entity that approves building permits, including those for
PV systems) and utility company—courtesy inspections and inspections at
the end of the completed installation.
Do a final walk-through with the customer, and have the customer sign off
on all of the installation details.
Reinspect your system after about 90 days, and complete a thorough systems
check. Retorque all of the mechanical and electrical components. This
inspection will accomplish a number of goals, such as:
Confirming and/or correcting any system conditions, both positive
and negative;
Allowing electrical and mechanical connections to set properly and
correcting any potential loose connections;
Testing strings to see if they are balanced; identifying potentially bad
panels, inverter challenges, and other defects in system operations that
will lower the PV system’s ability to produce energy.
