Self-Consumption
Use the solar energy you produce directly — power lights, appliances, and HVAC from your own rooftop, reducing reliance on the grid.
PUCT Registered · Sol-Ark Certified · Renon Power Partner
Power that protects what matters.
Lumis Energy designs, installs, and supports solar, battery storage, and resiliency systems for Texas homes, businesses, and critical facilities — engineered locally, backed for the long haul.
Why solar
Application scenarios for solar + storage.
From everyday consumption to grid-edge resilience, intelligent solar and battery systems unlock value across four core scenarios — for homes, businesses, and critical facilities.
Energy Surplus Management
Store excess solar production in batteries during the day, then deploy it at night or export to the grid for maximum value.
Peak Shaving
Discharge stored energy during high-demand windows to flatten load profiles, lower demand charges, and cut commercial utility bills.
Emergency Backup
Automatic islanding keeps critical loads running through outages, freezes, and grid instability — no interruption to what matters most.
