Why solar. Why now.
The sun is free. Your energy bill shouldn't be.
Lower Energy Bills
Most homeowners cut their electricity costs by 70–100%. Lock in a predictable rate while grid prices rise.
Energy Independence
Battery storage keeps your home running during outages. No more dependency on the grid.
Clean Energy
Every kWh you generate is a kWh that didn't come from a gas plant. Real carbon reduction, measured monthly.
Increase Home Value
Solar adds an average of 4.1% to home resale value — often exceeding the system cost.

How your system works
Sunlight hits your panels
Photovoltaic cells convert sunlight to DC electricity.
Inverter converts to AC
Your inverter transforms DC to the AC power your home uses.
Power flows to your home
Electricity flows to your appliances, lights, and devices first.
Surplus goes to battery or grid
Excess generation charges your battery or earns net-metering credits.
