Your trusted partner for solar and battery storage solutions in the Rio Grande Valley. Power your home with clean, reliable energy and gain energy independence.

What is home battery storage?

A home battery system stores electricity — typically generated by your solar panels during the day — for use later. It provides backup power during grid outages and allows you to use stored energy at night or during peak rate hours instead of drawing from the grid.

How long do home batteries last?

Quality home batteries like Tesla Powerwall come with 10-year warranties and typically last 15-20+ years with minimal degradation. They're designed for thousands of charge cycles, making them a long-term investment in your home's energy independence.

How much does a home battery cost in Texas?

A typical home battery system (like Tesla Powerwall) costs $18,000–$22,000 installed. Most homeowners qualify for $0 down financing, spreading the cost across monthly payments. Contact us for a free custom quote based on your home's needs.

Will a home battery keep my home powered during an outage?

Yes. A home battery automatically switches to backup mode when the grid fails, providing power to your home's selected circuits or whole home depending on system size. Your AC, refrigerator, lights, and essential appliances keep running without interruption.

How much backup power do I need?

It depends on what you want to power. Essential loads (fridge, lights, medical devices) require 5–10 kWh. Whole-home backup including AC requires 13.5+ kWh. We design a system right-sized for your specific needs and usage patterns.

Can I add a battery later if I start with solar only?

Yes. We design solar systems with battery compatibility in mind. Adding battery storage later is straightforward and doesn't require a full system redesign. Many customers start with solar and add a battery when they're ready.

Does a battery work without solar panels?

Technically yes, but a battery alone will eventually run out. A battery truly shines paired with solar — your panels recharge it during the day, giving you effectively unlimited backup power. Without solar, battery alone provides limited backup duration.

What happens to my battery during a power outage?

When the grid goes down, your battery automatically detects the outage within milliseconds and switches to backup mode. It seamlessly powers your home's critical loads or whole home depending on system size. Your AC, fridge, lights, and other essentials keep running.

Can I use my battery to reduce my electric bill?

Absolutely. By using stored solar energy at night or during peak rate hours, you reduce what you buy from the grid at higher rates. You can also maximize savings during peak demand periods when utility rates spike.

What's the difference between battery systems?

Quality varies significantly. We install proven systems like Tesla Powerwall and LG Chem RESU with 10-year warranties and long track records. Cheaper systems may degrade faster or have less reliable backup capability. We recommend premium quality for long-term reliability.

How does a battery protect me from ERCOT grid failures?

When ERCOT fails (rolling blackouts, extreme weather), your battery keeps your home powered automatically. You don't depend on the grid for survival during outages. This is especially critical in Texas where grid failures are real and increasing.

Can I participate in a Virtual Power Plant (VPP) with my battery?

Yes. Some utilities and retail electric providers offer VPP programs where your battery can support the grid during peak demand in exchange for credits or payments. Your home still has priority access to your stored energy — the grid only uses excess capacity.

What maintenance does a home battery require?

Home batteries require virtually no maintenance. They have no moving parts and no fluid to change. We monitor your system remotely, and you can track performance in real-time via an app. Annual inspections are recommended but most batteries operate trouble-free for years.

How fast does a battery respond during an outage?

Most quality home batteries switch to backup mode in milliseconds — faster than you can notice. Your lights, AC, and appliances transition seamlessly from grid power to battery power with zero interruption.

What's the warranty on a home battery?

Most quality batteries come with 10-year warranties covering manufacturing defects and performance degradation. Many also offer coverage for weather damage and system failures. We'll explain the full warranty terms when you get your quote.

Do I own my battery or lease it?

With Solergy, you own your battery outright. You have full control, own all the benefits, and can make decisions about how it operates. Never lease a battery — ownership is always better financially and operationally.

Can I go fully off-grid with a home battery?

With solar + battery storage, you can achieve near-complete energy independence. You generate power via solar, store excess in your battery, and use it when needed. During sunny periods, you may produce more than you use. Most homeowners stay grid-connected for reliability and net metering benefits.

How does a battery handle extreme Texas heat?

Quality home batteries are engineered to operate reliably in extreme temperatures. They include thermal management systems to keep them at optimal operating temperature in 100°F+ Texas summer heat. We install systems rated for harsh Texas conditions.

What happens if my battery runs out during an outage?

If you have solar, your panels recharge it during daylight hours — providing indefinite backup during sunny outages. If night falls during an outage, you'll run on stored energy. A properly sized system covers most homes through a full night or longer depending on usage.

Can I monitor my battery from my phone?

Yes. Your battery system comes with monitoring software accessible via smartphone or computer. Track real-time charge levels, energy flows, and system status 24/7. You get complete visibility into your home's energy situation anytime, anywhere.

How Battery Storage Works

Simple in concept. Powerful in practice.

Home battery storage system mounted on exterior wall at night

Your Solar Panels Generate Power

During daylight hours, your panels produce more electricity than your home typically uses.

Excess Energy Charges the Battery

Instead of sending that energy back to the grid for a small credit, it's stored in your home battery for later use.

Battery Powers Your Home

At night, during peak hours, or when the grid fails — your battery seamlessly takes over and keeps everything running.

Automatic. Always On.

The system manages itself. No switches to flip, no action required. It just works.
