THE PACIFIC ENERGY DIFFERENCE
Solar designed around how your family uses power.
We design solar and battery systems using your measured electricity use, a model of your roof’s solar production, and operating results from thousands of Hawaiʻi systems.
Your actual usage. A more precise design.
Our direct HECO integration gives us your Green Button Data in 15-minute intervals, so we can size your battery using actual day and night consumption.
Better designs through real-world results.
We compare our past designs with ongoing performance data from thousands of Hawaiʻi systems, then use what we learn to refine the next design.
Monitoring that alerts you, 24/7.
Our system monitors performance and battery settings, sends alerts when it finds an issue, and guides you through outages and recovery. This ongoing care is included at no extra charge.
The Pacific Energy Difference
Your roof tells us what you can generate.
Your data tells us what you need to store.
A monthly bill adds up your electricity use. It cannot show how much of that use happens while your panels are producing—and how much your battery needs to cover later.
01 / SOLAR PRODUCTION
Understand what your roof can produce.
Solar exposure, shade, roof angle, orientation, and usable space guide panel placement and expected production. We model how much electricity your roof can generate and when it will be available.
02 / YOUR ACTUAL USAGE
Use your actual electricity data.
With your permission, we connect directly to Hawaiian Electric Green Button Data to see your measured usage in 15-minute intervals.
03 / SOLAR + STORAGE TOGETHER
Size the battery around your life.
We calculate how much of your solar power the house can use as it is generated, and how much needs to be stored for later. We also account for the appliances you want to keep running during an outage.
04 / REAL OPERATING RESULTS
Design with real-world results.
We check how past designs perform after installation. Those operating results help us test the assumptions behind your proposed system.
Why timing changes battery needs
Two homes. Same daily use.
Different battery needs.
Both homes use 30 kWh of electricity a day and have the same solar-production potential. The difference is when they use their power.
Daytime: use solar as it’s madeEvening + overnight: use stored energy or the grid
HOME 2
Uses more power after sunset
30 kWh used each day
8 kWh
During solar hours
22 kWh
Evening + overnight
This home needs more stored solar energy to cover its evening and overnight use.
More battery storage needed
Home 2 uses more than twice as much electricity after sunset.
It needs more battery storage to cover that use. A monthly bill alone won’t show this difference. Your 15-minute Green Button Data helps us size storage for your household.
Illustrative electricity use, not recommended battery capacities. Actual sizing also accounts for solar production, backup priorities, energy losses, and equipment limits.

Equipment selected for your home
Solar Panels
We install Tesla, Qcells, REC, JA, and SILFAB solar panels. We choose panels and plan their layout around your roof’s solar exposure, shading, available space, and energy needs, then match that production with the right battery capacity.
Tesla Powerwall Batteries
Tesla Powerwall stores solar energy for later use and backup power. We size storage around your measured electricity use and the appliances you want to keep running, then monitor settings and performance after installation.
Enphase Microinverters
Enphase microinverters convert solar energy into usable electricity at each panel. Because they operate independently, a shaded or underperforming panel does not limit the others in the same way as a shared string inverter.
Enphase Batteries
We install Enphase batteries as part of a solar and storage system designed around your home. Your actual usage and backup priorities guide the capacity, and our included monitoring and alerts help you manage the system after installation.
Sigenergy Batteries
We install Sigenergy batteries with compatible solar equipment to meet your energy and backup needs. We use your measured usage to plan storage capacity and provide ongoing monitoring, alerts, and guidance after installation.
