Frequently Asked Questions
What services does Nabu Energy offer?
Nabu Energy is a leading solar installer in California. We specialize in designing and installing
customized solar panel systems, and we are also certified to install battery storage systems (such
as Tesla Powerwalls 3) and electric vehicle (EV) chargers. In other words, we help homeowners
and businesses go solar, add backup power, and set up home EV charging. Our certified team
uses high-quality, industry‐leading equipment for all installations.
Who are Nabu Energy’s customers, and where do you serve?
Nabu Energy serves both residential and commercial customers. We focus on California’s Bay Area (including San Jose, Sunnyvale, Fremont, and surrounding communities). Whether you own a home or a business in the Bay Area, Nabu Energy can design and install a solar-plus-battery system for you. In fact, Nabu Energy is “dedicated to serving customers in residential, small, and large commercial sectors” in the Bay Area.
What is the installation process, and how long does it take?
After an initial consultation and site assessment, Nabu Energy’s engineers handle the entire installation process. This includes system design, obtaining local permits, and scheduling inspectors. The physical installation usually takes only a few days, but the full process (including permitting and utility interconnection) typically spans several months. Industry guidance suggests a best-case timeline of about 4 months, while allowing up to 8 months to accommodate permits and approvals. In our experience, we communicate clearly every step of the way – customers report that our team provides a “smooth installation process” and keeps them updated throughout.
What kind of support do you provide after installation?
Nabu Energy’s service doesn’t end when the panels are on your roof. We provide proactive post-installation support: our team monitors system performance, helps troubleshoot any issues, and coordinates with equipment manufacturers for repairs or replacements under warranty. Many customers praise our follow-up – we keep clients informed after the install and ensure systems meet their promised output. In short, we stand behind our work and remain available to answer questions or resolve problems long after the project is complete.
How do I get started or request a quote?
Getting started is easy. You can contact Nabu Energy through our website or by phone to request a free consultation. One of our solar experts will assess your energy needs, explain your options (system size, battery needs, etc.), and provide a transparent estimate. Our process is consultative and education-focused: we answer all questions, explain costs and incentives in plain terms, and help you make an informed decision. Many customers comment on the clarity and transparency of our proposals, and we aim to make the transition to solar as straightforward as possible.
