To cover around 100% of their electrical usage with solar power as a long-term investment in their energy future.
Panel placement options:
The great this about this project was the client was very open to different options of where to locate the solar panels. During the site survey, we discussed the option for a ground-mount solar array near the house, an array on the garage by the house, and an array on the house itself. However, after looking at all of these options and looking at the cleanest ways to run wiring we decided the shop was the best option. A perfect south-facing roof, a clean way to run PV wiring over the roof, and easy access to the sub-panel for the AC connection
We decided on 2 designs with an option for expansion in the future. The great thing about Eagle Colorado is it gets a tone of sunlight.
After a review of the design, the client decided they preferred the aesthetics of the 16kWp design with the solar panels in portrait orientation.
After deciding on the array size and location the next step is deciding how we want to mount the solar panels to the roof and how we want to run the wiring. On this project the building had a corrugated metal roof so we decided on the following:
S5 corrugated roof mounts
IronRidge L feet, rails, and rail mount roof box
Q.cell G-10 400w BLK panels
For wiring, as we did not want to penetrate the metal roof we decided to run a conduit from the solar array up and over the valley and drop over the north side of the roof. Once this has all been decided and reviewed by the customer and they have receiver HOA/DRB approval the proposal is sent off for engineering.
Permitting and paperwork:
Once the design and products have been finalized the next step is the permitting and the paperwork. A full site survey is carried out with details on the interconnection to Holy Cross Energy, structural survey, and materials to be used. This is all sent on to engineering for plan sets to be drawn and structural and electrical engineering review and stamping.
Once we have received all this back we can then submit this to Eagle County with the HOA/DRB approval for permitting.
The final step in this process is to apply to Holy Cross Energy for approval.
Once all has been approved and finalized it’s time to schedule the installation of the PV system. This project ended up being a July install and took around a week.
The final Step:
After the installation of the PV system is complete it’s time to set up and commission the system and leave it turned off for Holy Cross Energy to test and energize.

- HOA/DRB approval
- Contract and deposit
- Site Survey and paperwork
- Energy provider interconnection application
- Interconnection application approval
- Material procurement
- QC and commissioning
- Energy provider testing
- powering up the system
What the customer thinks 6 months on:
“We hired Sean and his team at SunPak Electric to convert our home in Eagle Colorado to solar power. The SunPak team is great! How nice to work with someone who always responds to emails and phone calls timely while also delivering a professional job with no surprises. The quote we received was reasonable and the system was sized appropriately. We opted for net metering and did not install batteries. Holy Cross Energy needs to approve the system design prior to installation. Sean was very helpful walking us through our part of the submittal to Holy Cross. Once we were done, SunPak worked independently with Holy Cross to get the system design approved. The design approval went smoothly. SunPak then completed the installation of our 40 solar panels, the inverters and the connection to our existing electrical service. This work was done quickly and professionally. The job site was always neat and clean. Next, the completed project was inspected and approved by Holy Cross without issue. The system works flawlessly. We are now enjoying the benefits of producing our own electrical power! We could not be happier with the work done by SunPak and highly recommend them!”
