When the grid goes down
Keep the essentials running when the grid goes down.
Every package includes a battery. Pick what you’d keep on and see about how long each package carries it. One battery doesn’t back up the whole house — you choose what stays on.

About 18 hours on Basic, 49 on Optimal, 98 on Premium, for a 235 W load.
Estimate, not a promise. Real runtime depends on your appliances, the weather and your settings. Battery sizes from the Enphase and Tesla datasheets; 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).
Where these numbers come from
- Refrigerator, 60 W: about 490 kWh a year for a full-size ENERGY STAR model (estimate)
- Chest freezer, 25 W: about 215 kWh a year (ENERGY STAR)
- Lights, 10 LED bulbs, 100 W: 8–12 W per bulb (estimate)
- Wi-Fi router and modem, 25 W: 15–35 W together (estimate)
- Phones and a laptop charging, 50 W: typical charger ratings (estimate)
- CPAP or medical device, 55 W: about 35–105 W depending on settings (estimate)
- TV, 50–55 inch, 90 W: about 77–104 W (estimate)
- Two ceiling fans, 100 W: 10–100 W each (Mass.gov)
- Gas furnace fan, 450 W: 60–900 W depending on the motor (estimate)
- Central AC, 3-ton, running nonstop, 3,500 W: 3,500–5,000 W while running (estimate)
Three packages, turnkey
Design, equipment, permits, installation, switch-on. One price, and you own it.

Prices are for the complete system, installed, before any state incentives. Your exact price depends on your home; we confirm it on the call. Your estimate shows the plan for all three packages under South Carolina’s rules. 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.

Questions
Straight answers.
What people ask us most, with the rule or the number behind each answer.
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?
Duke Energy’s Solar Choice credits extra power at a rate we haven’t confirmed for South Carolina (sources range from about 4¢ to 11¢). Until we confirm yours, we use a cautious 4¢, so your system is sized not to fall short.
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 South Carolina incentives or tax breaks?
South Carolina solar tax credit: 25% of the cost; each year you can use up to $3,500 or half of your state income tax, whichever is less, and amounts over $3,500 carry forward up to 10 years (S.C. Code 12-6-3587, form TC-38).
Home solar systems up to 20 kW, including battery storage, are exempt from South Carolina property tax (S.C. Code §12-37-220(B)(53)). Our research found no sales tax exemption for home solar.
We don’t give tax advice — please talk to your tax professional.
What does the battery do for me?
Extra solar power is credited for less than you pay, so a battery lets you use more of your own. It also keeps essentials running when the grid goes down.
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 South Carolina?
South Carolina Residential Specialty Contractor registration (LLR), solar.
Are you a government program or my utility?
We're a private company from New York. 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.
Who covers the equipment?
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.
Our installation and roof warranty is ours — 25 years, in writing.
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. 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 (333) 555-4090, during South Carolina 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.
