Residential Solar Applications

1. Solar Electricity (Photovoltaics)

Photovoltaic (PV) panels made from materials like silicon convert sunlight directly into electricity. These panels are now common on rooftops, in large ground-mounted arrays (solar farms), and even portable devices. Advances in efficiency, such as bifacial cells and perovskite materials, continue to reduce costs and expand where solar power is feasible—from urban homes to remote outposts. Learn more about our residential solar panel installations that are transforming Texas homes.

2. Solar Water Heating

Solar water heating systems use sunlight to heat liquid in rooftop collectors, providing hot water for bathrooms, kitchens, and even industrial processes. Modern systems can include evacuated tubes or flat-plate collectors, integrated with backup electric or gas heating for overcast days. This technology pairs perfectly with home battery backup systems to ensure hot water availability even during power outages.

3. Solar Space Heating

By using liquid-based or air-based solar collectors, solar energy can warm internal spaces in homes or office buildings. Passive solar design—through orientation, window placement, and insulated thermal mass—maximizes sunlight through architecture. For comprehensive home comfort, consider combining this with our HVAC services for year-round climate control.

4. Solar Ventilation

Solar-powered attic fans and wall ventilators remove excess heat and moisture, making buildings more energy-efficient. They help maintain comfortable temperatures and prevent mold, working whenever the sun is shining.
