Big Island solar installation & battery storage
Big Island solar and batteries. Designed around your life.
Your home’s solar potential and your family’s daily routine shape the system you need.
With your permission, we connect directly to Hawaiian Electric Green Button Data to see how much electricity you use in each 15-minute interval. We match that usage with expected solar production to size your panels and battery storage together.
We install solar and batteries for Big Island homes and businesses. Pacific Energy grew in Hawaiʻi and has offices on Maui and Oʻahu.

The right design starts with your home.
Understand your solar potential.
Sun and cloud patterns vary across Hawaiʻi Island, from Hilo to Kona. We model solar exposure, shading, roof orientation, and usable space at your property to estimate how much power your panels will produce and when.
Measure when you use power.
Hawaiian Electric Green Button Data shows electricity use in 15-minute intervals. Comparing that pattern with expected solar production helps us decide how much energy can be used directly and how much needs to be stored for later.
Design for savings and backup.
We size battery storage for your evening use and the appliances you want to keep running during an outage. Measured usage helps us balance daily savings with the backup protection you need.
Learn from real-world performance.
We compare our past designs with ongoing performance data from thousands of systems across Hawaiʻi. Those results help us refine new designs and recognize when an installed system needs attention.
Included monitoring, alerts & guidance • 24/7
A precise design is just the beginning.
Our system checks battery settings and production 24/7 and messages you when it finds an issue. If your production drops while nearby systems are running normally, we can flag a possible equipment problem. Monitoring, alerts, and guidance are included at no extra charge.
During an outage, we alert you that you’re on backup power, show your battery charge and estimated runtime, and prompt you to reduce power use when needed. If the battery runs empty, we guide you through preparing for a restart and alert you again if more appliances need to be turned off.
Explore the Pacific Energy Difference →Residential solar for Big Island homes
Our residential solar systems use Tesla, Qcells, REC, JA, and SILFAB solar panels; Tesla, Enphase, and Sigenergy batteries; and Enphase microinverters. We select compatible equipment around your property, measured usage, and backup needs.
We coordinate design, permitting, utility approvals, and installation. Your proposal explains the equipment, expected performance, and the steps to get your system running.
Commercial solar for Big Island businesses
We design commercial solar for properties from multi-family housing to industrial facilities. Your operating hours, equipment demand, and business priorities guide the system.
Our equipment lineup includes Tesla, Qcells, REC, JA, and SILFAB panels; Tesla, Enphase, and Sigenergy batteries; and Enphase microinverters. We select compatible equipment for the project and plan generation and storage together to reduce electricity costs and support essential equipment during outages.
Coordinate roofing and solar
A sound roof is part of a lasting solar installation. We offer standing seam metal and composite roofing and can coordinate roof replacement with solar installation. Planning both together helps reduce disruption and avoids putting new panels on a roof that will soon need work.
Plan your Big Island solar project
We work with homeowners, businesses, and community facilities across Hawaiʻi Island. Start with a conversation about your property, electricity use, and goals.
We’ll explain your options and prepare a proposal showing how solar and storage can work together for your property, with a clear path from design through installation.
Schedule your free consultation to discuss solar, battery storage, or roofing for your Big Island property.
Big Island solar questions
Questions about installing solar and batteries on Hawaiʻi Island.
Is solar worth it on the Big Island?
Solar can reduce the electricity you buy from the utility. How much you save depends on what your property can generate and how much of that energy you can use during the day or store for later.
We use your measured usage, your property’s solar potential, and real operating results to estimate the benefits for your home. Your proposal shows the assumptions behind the design and projected savings.
How much does solar cost on the Big Island?
The cost of solar panels is only part of the project cost. Battery capacity, roof repairs, and electrical upgrades can also change the price. We review those before preparing your proposal.
We’ll explain what is included in the quote and review financing options so you can compare upfront costs, payments, and expected savings.
Do I need battery storage with my solar panels?
A battery is not needed for every project, but battery storage lets you save solar energy for evening use and can provide power during an outage. We use your actual consumption pattern and backup priorities to determine whether storage makes sense and how much you need.
We install Tesla, Enphase, and Sigenergy batteries. We select compatible equipment and size storage around your measured usage and backup priorities, with ongoing monitoring and alerts included at no extra charge.
What solar incentives or tax credits are available in Hawaiʻi?
Hawaii maintains a Renewable Energy Technologies Income Tax Credit for qualifying renewable-energy systems. Tax rules can change, so Pacific Energy recommends discussing eligibility and potential tax benefits with a qualified tax professional.
How are solar systems designed for tropical weather?
Roof condition, mounting, and the conditions the system is engineered for matter as much as the panels. Our design review covers the roof and installation requirements. For supported systems, our monitoring also checks storm readiness and alerts you if nearby systems have entered storm mode but yours has not.
How long does solar installation take on the Big Island?
Installation is one part of the schedule. Design, permits, utility approvals, and inspections also take time. We’ll give you a project-specific estimate and explain which steps depend on outside approvals.
How do you help protect my solar savings over time?
If a high backup reserve is left in place after a storm, it can reduce the energy available for daily use and increase what you buy from the grid. Our system checks supported reserve, utility-program, and export settings, alerts you to issues, and explains what to change.
What system is best for my Big Island home?
The best fit depends on your property, measured usage, budget, and backup priorities. We use Hawaiian Electric Green Button Data to see when your home needs electricity, then design solar and battery storage together around those needs.
Can I add batteries to my existing solar system?
Often, yes. We review compatibility and combine your existing system’s reporting with Hawaiian Electric Green Button Data to design an expansion or replacement around your actual usage. We also consider the appliances you want to keep running during an outage.
