Solar and Storage Microgrids in San Antonio, Texas

Strengthening Energy Security With Smart Storage Solutions 

When the grid goes down, most solar systems without storage go down with it, leaving homes and businesses without power exactly when they need it most. Central Texas Solar designs solar and storage microgrid systems that keep critical power running through outages, combining solar generation with battery storage and smart controls. This approach turns a standard solar setup into a more resilient energy system capable of operating independently when the broader grid can't.



We design and install solar and storage microgrid systems for properties throughout San Antonio, Texas, and surrounding areas across Central Texas. Severe weather events and occasional grid instability in this region make backup power planning especially relevant for both homeowners and business owners. Our team accounts for these regional realities when sizing battery storage and microgrid controls, ensuring the system actually meets demand during real outage conditions.


Drawing on 100 years of combined experience across solar installation and energy systems, our team understands how to integrate storage and controls without compromising the performance of the original solar array. We treat microgrid design as a complete energy strategy, not an add on, pairing it with solar installation and maintenance for long term reliability.

Benefits of Solar & Storage Microgrids

Reliable Backup Power

Unexpected outages can disrupt daily activities, business operations, and essential services. A properly designed microgrid provides dependable backup power for critical systems, helping maintain functionality when utility service becomes unavailable and reducing uncertainty associated with prolonged power interruptions and emergency situations.

Greater Energy Independence

Producing and storing your own electricity reduces dependence on traditional utility providers. Greater energy independence offers increased control over power availability and consumption, helping property owners navigate grid instability, fluctuating rates, and service disruptions with greater confidence and long-term flexibility.

Protection During Grid Outages

Weather events, infrastructure failures, and utility disruptions can leave properties without power unexpectedly. A microgrid keeps designated circuits operating during outages, helping protect essential systems from interruption. This added resilience minimizes disruption while supporting comfort, productivity, and operational continuity throughout emergencies.

Optimized Energy Storage

Intelligent storage management helps maximize the value of stored electricity. Smart controls determine when energy should be reserved, consumed, or replenished, balancing everyday needs with backup preparedness. This optimization supports efficient operation and extends available power during prolonged outage conditions.

Reduced Reliance on the Utility Grid

Generating and storing more of your own electricity decreases the amount of power required from utility providers. Reduced grid dependence provides greater control over energy usage, helps limit exposure to service disruptions, and supports a more stable long-term energy strategy overall.

Smarter Energy Management

Advanced microgrid controls automate decisions regarding energy production, storage, and consumption.
