Commercial solar, battery storage & roofing on Kauaʻi
Kauaʻi commercial solar.
Built around your business.
A daytime shop and a business that stays busy after sunset need different amounts of stored energy. Your solar and battery system should reflect how your business uses power.
We use your electricity records and any existing system reports to understand demand, then model solar production at your property. That shows how much power the business can use during the day and how much it needs to store.
Pacific Energy is a locally grown Hawaiʻi company with offices on Maui and Oʻahu, serving commercial projects on Kauaʻi.

Start with how your business runs.
Design around your operating hours.
We review available usage records and system reports alongside your operating schedule. That helps us understand how much solar power your business can use during the day and how much energy needs to be stored for later.
Make the most of your roof.
We model solar exposure, shading, roof orientation, and usable space to estimate production. If your roof needs work, we can plan roofing and solar together to reduce disruption.
Keep essential equipment running.
Tell us what your business needs during an outage, from refrigeration to critical equipment. We use those priorities and your available usage data to plan battery capacity and explain how long backup power is expected to last.
Learn from real-world performance.
We compare past designs with ongoing performance data from thousands of systems across Hawaiʻi. Those results help us refine new designs and spot systems that need attention.
Solar planning for Kauaʻi.
We plan your project around your property and the requirements of Kauaʻi Island Utility Cooperative (KIUC), coordinating the utility approvals needed for installation.
How do you assess my business’s energy needs?
We use available customer usage records and the reporting from any existing solar or battery system, alongside your operating hours and equipment needs. Together, they help us plan generation and storage around how your business actually uses electricity.
What happens after installation?
Our monitoring operates 24/7. It checks supported battery settings and compares production with nearby systems, then sends alerts and guidance when it finds an issue. During outages, it helps you manage available power and prepare for recovery. This ongoing care is included at no extra charge, with monitoring features matched to your equipment.

We choose equipment based on the capacity you need, what works with your building or existing system, and the equipment you want to keep running. Our options include:
- Tesla, Qcells, REC, JA, and SILFAB panels – Solar panels selected to suit your roof, production goals, and available space.
- Enphase microinverters – Convert power at each panel, allowing the other panels to keep generating when one is shaded or underperforming.
- Tesla, Enphase, and Sigenergy batteries — We compare storage capacity, backup output, and compatibility with your solar system before selecting equipment.
We coordinate design, engineering, permitting, utility approvals, and installation. After your system is running, monitoring and proactive guidance help protect the savings and backup power it was designed to deliver.
What your business can gain
We’ll show how much electricity the proposed system could supply, what it could save, and which equipment it could power during an outage. Those estimates give you a basis for deciding whether the investment fits your business.
The proposal covers:
- Expected electricity savings
- Backup capacity for essential equipment
- Battery capacity and how it matches your operating schedule
- Equipment and warranty coverage
- Ongoing monitoring and alerts at no extra charge
Plan commercial roofing and solar together
Your roof needs to support your solar system for years to come. Our commercial roofing services let you coordinate roof improvements with solar installation.
One team coordinates both projects, helping reduce downtime and avoiding the need to remove newly installed panels for roof work later.
We install standing seam metal and composite roofing for commercial properties. We’ll review your roof’s condition and explain whether repairs or replacement should come before solar.
