Ownership
You buy the system. It’s yours from day one. No lease, no PPA. Our own crews install it. We don’t subcontract.
Take the proposal home. You don’t have to sign anything today.
How it’s installed
Skip the 3D story3D model, not your house. Your design starts from a snapshot of your roof.
How it’s installed
From a bare roof to your own power plant.
- 01
Your roof, measured
We start with a snapshot of your roof and design where every panel goes — before anyone climbs a ladder.
- 02
Mounts, sealed
Our own crew fastens the mounts and seals every roof penetration. Our roof warranty: 25 years, in writing.
- 03
Panels on the rails
Qcells or REC panels go on in the rows you approved in the design. We don’t subcontract.
- 04
A battery in every package
Basic: an Enphase IQ Battery 5P (5 kWh). Optimal: one Tesla Powerwall 3 (13.5 kWh). Premium: two (shown here), plus a SPAN smart panel and an EV charger. Gateway 3 switches your home to battery power when the grid goes down; you choose what stays on.
- 05
Inspection, then switch-on
The city inspects the work. Your utility gives permission to operate. Then it’s yours. From contract to switch-on: up to a month.

When the grid goes down
Keep the essentials running when the grid goes down.
One Tesla Powerwall 3 stores 13.5 kWh and delivers 11.5 kW continuously. One battery doesn’t back up the whole house — you choose what stays on.
One Powerwall 3 · 13.5 kWh
about
Two Powerwall 3 (Premium): about 98 hours. Your load: 235 W.
Estimate, not a promise. Real runtime depends on your appliances, the weather and your settings. Battery size from the Tesla Powerwall 3 datasheet; freezer from ENERGY STAR; ceiling fans from Mass.gov; other loads are typical estimates. We assume 85% of stored energy reaches your outlets. Solar recharging during the day isn’t counted. Without power, a refrigerator keeps food cold for about four hours (Ready.gov).
Three packages, turnkey
Design, equipment, permits, installation, switch-on. One price, and you own it.
Delaware rules limit home solar to 110% of your use, so our packages start at $0 for electricity and a small bill returns later. Your estimate shows it for your home. Fixed utility charges still apply. A design goal, not a guarantee.

We check your roof’s age before we install. Then our crew seals every penetration and our roof warranty covers it.
Who’s responsible for what
Manufacturer warranties apply under each maker’s terms. Some — Tesla, FranklinWH, REC ProTrust — require a certified installer and product registration; ask us about it before you sign, and check the final warranty documents.
Reviews
What homeowners say.
“Great job by the Renewable Energy team installing our Tesla Solar Roof and Tesla Powerwall in our home in Los Angeles. The install went great and they worked well with LADWP to get us up and running!”
— Michael Freiwald
Los Angeles, California
“I was really happy with the service I received from Renewable Energy. All of the staff from sales to installers to support were very professional and frequently communicated about the status of the project. They designed the system based on my usage patterns and predictions about annual solar production based on my roofline and location. They handled all of the paperwork with SCE and made the whole process very easy. They continued to communicate once the system was up and running and provided tips for how to configure the new Tesla battery system they installed and it is working great, so far I’m 98% off grid, which includes keeping my Tesla car charged up. Great experience overall, I highly recommend Renewable Energy!”
— Brian Jorans
Homeowner
“… They give strong guarantees for their work, and will still be around to provide service if you need it. Once you sign a contract you can sit back and relax as they will handle everything from start to finish. Being an Architect (retired), I know how construction should be done and I have been very satisfied with their work. I highly recommend them!”

A few questions about your home and your bill. You don’t have to sign anything.
Questions
Straight answers.
What happened to the federal solar tax credit?
The federal 25D tax credit ended for systems installed after December 31, 2025. Our numbers don’t include it.
We don’t give tax advice — please talk to your tax professional.
Can I change my mind after I sign?
Take the proposal home. You don’t have to sign anything today.
If you sign at your home, the federal FTC Cooling-Off Rule gives you until midnight of the third business day after the sale to cancel, with no penalty.
What happens to the extra power my panels make?
Delmarva credits each kWh you send to the grid at the retail rate. Home systems are capped at 25 kW.
Buyback rules are set by your utility and state regulators. We don’t control them, and no one can guarantee them for years ahead.
Are there Delaware incentives or tax breaks?
Our research found no state cash incentive or tax credit for home solar we can count on.
Delaware has no sales tax at all, so none applies to the system. Our research couldn’t confirm a statewide property tax exemption for home solar; your county assessor can tell you.
We don’t give tax advice — please talk to your tax professional.
What does the battery do for me?
With 1:1 net metering, power you send to the grid offsets power you buy later, so a battery mostly adds backup — it keeps essentials running when the grid goes down. Any savings from a battery we calculate with your real bills.
Every package includes a battery: Basic — an Enphase IQ Battery 5P (5 kWh), Optimal — one Tesla Powerwall 3 (13.5 kWh), Premium — two (27 kWh). One battery doesn’t back up the whole house; you choose what stays on.
What licenses apply in Delaware?
Our research found no statewide solar contractor license in Delaware; a business license and local permits apply.
License details for every state we serve are on our Licenses page.
Are you a government program or my utility?
We're a private company from Montana. We supply and install solar and battery systems, with our own crews in all 19 states we serve. Not a government program, not your utility.
We don’t offer free panels.
What if your company goes out of business?
Your panels, inverter and battery stay covered by their manufacturers’ warranties, under each maker’s terms (some require a certified installer and product registration). Our installation and roof warranty is ours — 25 years, in writing. Keep all your documents.
Will solar panels damage my roof?
Our own crews install every system; we don’t subcontract. Every roof penetration is sealed and covered by our written roof warranty for 25 years. We check your roof’s age before we install.
Will I really pay $0 for electricity?
We design every system for $0 for electricity: your panels are sized to cover what you pay for electricity every year for 25 years, at today’s prices. Where your utility limits how big a system can be, your estimate shows what’s possible.
It’s a design goal, not a guarantee: your use, the weather and your utility’s rules can change. Fixed utility charges still apply.
Who will call me, and when?
Our own team, from , during Delaware calling hours: 8 AM–9 PM, your local time. We call by hand and don’t text. Tell us any time to stop, and we stop.
How long until my system is on?
Usually up to a month from contract to switch-on. Permits and your utility’s approval set the exact date.
Who services my system after installation?
We do. Our own team services your system after installation and checks it every six months.
