Ordering Equipment

When you have your design and permits ready, it is time to order your equipment. Most components can be ordered using the HAREI discount, and some simpler items can be obtained locally; HAREI can help you organize and put in your orders.

If you are part of a HAREI group order, your shipping will be covered by our Renvu MegaWatt Club membership; your cost is just your $150 share of the MegaWatt membership fee.

You can make your membership and MegaWatt club contributions on our Contacts page.


If your installation is a ground mount, prepare the structure. If your roof requires reinforcing, this should be done first.
HAREI members have experience with many aspects of this and can provide advice on equipment and techniques.

Racking and inverter installation

  1. Attach the mounting rails to the structure
  2. Mount the microinverters to the rails (depending on your design, it may be easier to do this before you mount the rails).
    As you do this, record the position of each microinverter on the map grid provided with them (you will use this later to set up your grid monitorin
  3. Attach the Enphase trunk cables to the rails and connect each inverter to the trunk cable.

Electrical Connections

You should use a licensed electrician to create the proper connections between your main electrical panel and your array based on this wiring plan.

Electrical System Labels - There are a number of places on your system where special labeling is required. Which labels are required depend to some extent on your local building code - ask your building inspector which version of the National Electrical Code they use. You can buy labels for any version of the NEC at PV LABELS .com

Solar Raiser - install solar panels

  1. Schedule your Solar Raiser
    Organize HAREI volunteers to come and help mount all your panels (you should of course also plan to participate in at least a few of these, both to do your share and to see how it’s all done).
  2. Execute the Owner Hold Harmless agreement for HAREI (required to hold the Raiser)
  3. Have each volunteer for the Raiser execute the Volunteer Hold Harmless document
    It is in the homeowners best interest to ensure everyone has done this and you are responsible for making sure they do.
  4. Mount the panels and connect to inverters.
    At this point, your disconnect switch should be off so that no power will be produced yet, but your inverters will indicate that they are ready to be connected (red flashing signal)
    (you'll be tempted to turn the system on to see that it works - because you do not yet have a Net Meter installed, if you do you'll actually be paying the electric company for the power your system produces).

There are just a few steps left before you can activate your system; see Finishing.
