Answers for Maui Homeowners

Solar comes with a lot of questions, and most homeowners have some version of the same ones. Here are honest, straightforward answers to the ones we hear most — with a link to the full page if you want the longer version.

Getting Started

  • How much does solar installation cost on Maui?

    It depends on system size, equipment choice, and whether battery storage is part of the project — we'll walk you through the specifics for your home rather than quote a generic number up front. See our Solar Cost & Pricing Guide for a fuller breakdown.

  • How many solar panels do I need for my Maui home?

    It comes down to your roof size, your household's energy use, and your goals — whether that's covering most of your bill or getting close to fully offsetting it. More detail on our Solar Installation page.

  • Is solar worth it in Hawaii in 2026?

    For a lot of homes, yes — but it depends on your roof, your usage, and current incentives, not a blanket answer. See Why Solar in Hawaii for the full picture.

Battery Storage & EV Charging

  • Can I add battery storage to my existing solar system?

    In most cases, yes. We'll look at your current system's inverter and setup first to confirm what's compatible before recommending a battery. More on our Battery Storage page.

  • What brands of solar batteries do you install?

    We work with Franklin and have experience with Tesla, Enphase, Sol-Ark, and SIG Energy — the right choice depends on your home and goals, not a single brand we default to.

  • Can you install an EV charger at my home?

    Yes — home EV charging installation is one of our core services, whether you already own an EV or are planning to buy one. More on our EV Charging page.

Aging Systems & Reroofing

  • How do I know if my solar system needs to be upgraded?

    Signs include declining output, equipment that's 15+ years old, or a system that no longer matches your household's energy use. We'll look at your existing setup honestly before recommending an upgrade. More on our Solar Panel Replacement & System Upgrades page.

  • Should I reinstall or replace solar panels when reroofing?

    It depends on your system's age, condition, remaining useful life, and the warranty a new system would carry — there's no single right answer for every home. See our Reroofing & Solar page for the full comparison.

Incentives & Financing

  • Does Hawaii still have a federal solar tax credit?

    No — the federal residential credit ended for systems installed after December 31, 2025. Hawaii's own state credit is still active but is changing under recent legislation. See Hawaii Solar Incentives for current details.

  • How does Hawaii's GEM$ on-bill program work?

    It's a state-administered financing option where qualifying homeowners repay the cost of a system through their electric bill rather than a separate loan. See our Solar Financing Guide for how it compares to a loan or cash purchase.

  • Is a solar loan or GEM$ better for financing?

    It depends on your eligibility and what you value more — a fixed loan structure or on-bill repayment. We'll walk through both against your actual numbers rather than push one option.

Choosing a Company

  • What should I know before hiring a solar company on Maui?

    Ask about who actually does the work, how pricing is broken down, and what happens if your equipment underperforms. See Why Choose Us for the questions we think matter most.

  • Is Solar-HI Maui a legitimate solar company?

    Yes — we're based in Kihei, have been doing this work since 2006, and are recognized as an approved contractor under Hawai'i's GEM$ program. See our Reviews and About pages for more.
