Specialties / Additional Information

Our installation and service crews have all the skill sets needed to provide Solar Installations and to service existing Solar Electric and Solar Thermal systems. This experience includes hands on construction, assembly, installations, plumbing, electrical, design and site planning training.

Solar makes sense economically and environmentally so we see more and more consumers eager to learn more about becoming energy independent with a solar installation. Utility companies have what amounts to a "lifestyle" mortgage on homeowners that will never be paid off. Solar offers a solution that contrasts control over your own energy production against the continual cost increase of utility bills.
