Go back 20 years, and you'll see that designing and installing a solar/photovoltaic system was TOUGH.
An install consists of two parts: planning of the system design and the physical labor.
Planning your system used to require a deep understanding of volts, amps, watts, circuits, solar azimuths, photovoltaic sun potential, inner workings of the hardware and electrical components, wiring, etc.
But the industry has come a long way. . .
At Project Solar, we can now design your system within 24 hours, maximizing your system design for efficiency of panel placement, aesthetics, and ROI.
That just leaves the physical labor, and it's really not as difficult as it may seem. We even have a solar calculator to help you size your system.
In fact, you don't have to have an electrical background at all. If you can use a power drill to drive lags and run wires through your attic, you can install solar.
The 4 Steps to Install Solar
The purpose of this article is to illustrate the steps of an install. This is not a tutorial or a guide. Follow the provided install guides in your Project Solar user portal for more in-depth instructions.
Step 1. Drill in Anchors
After reviewing your provided plans and marking out the lines where your rails and anchors will go, you will find the studs/trusses in which to install your anchors.
Anchors are the waterproof attachment fixtures that the rails attach to. They can differ depending on the style of roof you have, but they all do the same job.
To install, you will drill a pilot hole into the truss. The anchor will then slide under the surrounding shingles (or interlock with a tile roof) where a lag bolt will hold it in place.
Do this for every anchor position as outlined by your engineering plans, and the hardest part of the solar install is done!
Step 2. Connect the Racking/Rails
This step goes quickly. Attach the rails/racking on which the panels will sit. These rails are rated to securely hold your panels through wind and snow.
Some rails will need to be extended with the provided extender insert and screws. Leave excess rail overhang until the panels are all on, and then cut the overhang.
This step should take less than 45 minutes.
Step 3. Attach the Panels
Project Solar builds include microinverters, so attach each microinverter where its associated panel will go. The trunk cable connects all the microinverters together and terminates into a junction box that transitions into the roof.
Attach each panel over the corresponding microinverter. Then, you'll be able to easily plug the panel wires into the microinverters.
Getting the panels on your roof is the most satisfying part of the install and is relatively quick depending on the help you have. Guides are available for how to carry a panel onto a roof by yourself. If you can handle 45 pounds, it's not too hard.
Step 4: Run the Wires
Once the panels are all installed and the trunk cable connecting the panels/microinverters are terminated into the junction box, all that is left is to run the wires through the attic (or EMT piping if your ceiling is vaulted and the wires need to stay outside).
Depending on your location's code, the attic run might entail threading wires through a flex conduit. This will be clear in your engineering plans.
Run the wires through the attic and exit the side of your house above your main service panel.
You're done! The last step is the interconnection between your system and your main service panel. Most customers contract a local electrician or handyman to complete this step, as it's the only part of the process that deals with live wires.
Project Solar's Services
From system design to power on, we are with you the entire way.
Project Solar will handle all the pre-install work, including system design, engineering, city and utility permitting, paperwork, and logistics. When the time comes, we'll ship all the materials right to your home.
On install day(s), professional installers will be available for remote assistance through text, calls, and/or video chat.
