We’re a local team on a
simple mission.

Solar shouldn't be confusing.

We're here to make it simple, honest, and actually save you money.

No high pressure sales. Just the help you need.

LUMI™ was built to be different.

We operate as your advocate, not just an installer.

Our goal is to run a rigorous ROI audit on your home’s energy profile, and we hold ourselves to a standard of radical transparency.

If solar doesn’t deliver a clear, long term financial advantage for your specific property, we’ll be the first to tell you to walk away.

Our Process

The Individualized Solar Roadmap

We guide you through a low pressure, data driven journey designed for the Arizona market. No fluff, just facts.

STEP 01

12 Month Bill Audit

We don't guess; we calculate. We analyze your last 12 months of utility statements to find your 'peak usage' triggers.

STEP 02

Specific Engineering

No 'cookie cutter' layouts. We design your array based on Arizona's specific solar irradiance and your roof's orientation.

STEP 03

"Hands Off" Permitting

The Valley’s permitting landscape is a maze. From HOA architectural committee approvals to municipal structural inspections and utility interconnection agreements, our local team handles 100% of the paperwork. You just watch the progress on your app.

STEP 04

Master-Class Installation

Our in-house master electricians treat your roof like the primary shield it is. We use top of the line inverters (certified for 140°F+ ambient temps) and low profile mounting systems that are engineered to withstand 60 mph monsoon winds and haboob dust infiltration.

STEP 05

Lifelong Post Install Advocacy

Most companies disappear after the 'Permission to Operate' (PTO) arrives. LUMI™ provides ongoing support, including annual performance audits and cleaning services to clear away desert soiling. We are your local partners, ensuring you are never an 'abandoned' solar customer.

FAQ

Your Questions, No Fluff

Addressing the specific skepticism of the Arizona homeowner with transparency.

No salesperson should promise a 'zero dollar' bill. Even with 100% offset, utility companies charge a fixed grid access fee (typically $20 - $30). Our goal is to eliminate your usage and demand charges, which make up the bulk of your costs.

Arizona dust (soiling) can reduce production by 5% to 15% annually. Our systems are designed for easy maintenance, and we recommend a professional cleaning twice a year—specifically after the summer monsoon season ends in September.

It depends on your goals: Ownership maximizes wealth through tax credits (30% federal + $1,000 state) and home equity, while Leasing offers a $0 down, maintenance free experience with immediate savings. During your ROI Audit, we’ll provide a side by side math comparison to see which model best fits your financial strategy.

With the shift from 'Net Metering' to 'Net Billing,' utilities now buy your excess power for 'peanuts' (roughly 6.8 to 9c per kWh). A battery allows you to store that power and use it yourself during expensive peak hours instead of selling it back for a loss.

We use 'bankable' hardware (Enphase, Tesla, Silfab) with 25 year manufacturer warranties that remain valid regardless of the installer. Furthermore, our 'Rosie style' ethics mean we use open source monitoring so any qualified local electrician can service your system.
