Solar water heating is still to this day a no brainer to invest in for a typical family four in most parts of the island. Heating your water in your home with a traditional water heater costs about 30-40% of your electric bill. By investing in a solar water thermal system, you can save on your electrical costs before taking the plunge with a photovoltaic solar system. Having said this, the ROI on a solar thermal system would be roughly 2-3 years with combine Federal and State Tax Credits.

In our installations we use all brass and copper fittings making sure your system far exceeds your return on investment. If there are consecutive rainy days, we have an electrical backup time to kick on as well as a simple controller to help when your ohana are away on vacation… Aloha Friday!

Our roofing department doing a roofing tear-down and re-roofing and lag pre-installation to prepare for a 20 panel PV installation (and solar water heating put-back).

Here are 5 key benefits for homeowners when choosing a solar company that also installs roofing:

* Reduced Stress: Dealing with a single company simplifies the entire process, minimizing stress and hassle.

* Accountability for Roof Penetrations: The company is fully responsible for any roof penetrations associated with the solar installation, ensuring proper sealing and minimizing potential leaks.

* Increased Efficiency: Streamlined project management and better coordination between roofing and solar installation lead to faster project completion.

* Enhanced Peace of Mind: A single warranty and support contact, along with improved quality control, provide greater peace of mind.

* Potential Cost Savings: Bundled discounts and streamlined project management can lead to potential cost savings.

If you don't have solar water heating, it should really be one of the first things home owners should invest in, especially if you have a growing family of four. Typically, these solar water heating unit's payback is about 2-3 years if you're in a good sunzone like Ewa, but even in lower sunzone areas like Kaneohe or Wahiawa, you'd be surprised how much off your electric bill this system will save you.

She is now cool and relaxing in her home and doesn't worry about the fluctuating electrical prices OR power outages anymore!
