Solar Electric Systems
Grid-interactive solar electric systems convert sunlight into usable electricity using crystalline silicon panels. Our installations include inverters that transform DC energy into AC power for immediate use or grid feed-back. Systems feature module-level optimization for improved efficiency in shaded conditions while maintaining 25-year performance warranties. The technology reduces energy costs through net metering arrangements with local utilities.
Electric Vehicle Charging
Level 2 high-current charging stations provide faster EV battery replenishment compared to standard outlets. Our licensed electricians perform electrical load calculations to ensure system compatibility. Installations integrate with solar electric systems for complete renewable energy solutions. All work includes safety certifications and ongoing technical support for residential and commercial applications.
Solar Energy Storage
Energy storage solutions enable solar power utilization during grid outages and nighttime hours. Certified installations from Generac, Enphase, and SolarEdge provide energy independence while optimizing cost savings through strategic energy management. Systems integrate seamlessly with new and existing solar arrays to maximize return on investment and energy security.
