Why now

Three reasons homeowners upgrade.

Battery backup

The Texas grid has failed twice in the last three years. A LiFePO4 battery keeps your lights on, fridge running, and AC humming for 24–48 hours during outages — and lets you arbitrage peak-time rates the rest of the year.

System expansion

Household electric use keeps going up — EV chargers, home offices, heat pumps. If your original system was sized for pre-2020 usage, you're probably underproducing now. Adding panels solves it.

Federal tax credit

The 30% federal solar tax credit still applies to battery and expansion projects. Get it now, before Congress changes the rules.

Pick your path

What kind of upgrade are you thinking about?

Wall-mounted home battery storage unit

Add battery storage

LiFePO4 backup (10–40 kWh) that works with your existing panels. Federal tax credit applies.

Roof with room to expand an existing solar array

Add more panels

Expand production capacity, take advantage of net metering — usually works with your existing inverter.

Modern home with full solar array and battery

Full system upgrade

Replace older panels with high-efficiency modern ones, add battery, maximize output.

Common questions

Upgrades, answered.

How much does adding a battery cost?+

It depends on the size you need — a 10 kWh backup runs meaningfully less than a 30+ kWh whole-home setup, and the 30% federal tax credit applies to the whole project. On the consult we size it to your actual usage and give you real numbers, not ranges from the internet.

Can I add a battery to any solar system?+

Almost always, yes. The path depends on your inverter type — some pair directly, others use an AC-coupled battery that works with anything. Bring your inverter brand to the consult and we'll design around it.

Will I lose my current tax credit if I upgrade?+

No. The credit you claimed on your original system is yours. Expansions and battery additions qualify for their own 30% credit on the new equipment.

Do I need to replace my existing panels?+

Usually not. We design upgrades around what you have. Full replacement only makes sense when panels are old or underperforming enough that swapping beats adding.

How much power does a battery give me during an outage?+

Depends on the size and what you run. A typical 10–20 kWh setup keeps essentials — fridge, lights, internet, some AC — going for 24–48 hours, longer with solar recharging it each day.

What's the ROI on battery-only vs battery + more panels?+

They're different plays: battery-only is resilience plus peak-rate arbitrage; battery + panels adds production. We run both scenarios side by side on the consult so you pick with real numbers.
