Elementary school teacher Marilyn Hamano went looking for a solar power company the way a student might solve a class problem.

“I had been researching photovoltaic systems for over a year, and I was determined to have one installed on my home by the end of 2012,” she said. “I looked at a lot of different companies and what they offered were all very similar.”

But when she looked into Bonterra Solar, she found what she was looking for: a company that only dealt in quality products, provided good service, answered all of her questions and, as she discovered, a company with a heart.


“I read about how Bonterra does pro bono work for Habitat for Humanity, the volunteer organization that builds homes for the needy at no cost,” she said. “I really liked that Bonterra gives back to the community.”

Habitat for Humanity: a natural fit for Bonterra

Bonterra Solar founder and principal Andrew Yani has made philanthropy a key part of his company’s mission.

“In 2009, we began providing a free solar water heating system for every Habitat for Humanity home built on Oahu,” Yani said. “Giving back is part of our philosophy. The sun gives us unlimited electrical power and we pass on those blessings to our customers and charities. That is especially important at this time of year when our thoughts turn to those in need.”

Bonterra also assisted the Department of Hawaiian Home Lands in developing Kaupuni Village, the first net-zero energy community in the nation. And Yani has recently become a Hawaii March of Dimes board member.


Employee’s dedication extends to schools


Hamano commended Bonterra employee Chad Horiguchi for not only educating her on her new PV system and answering all of her questions, but for going a step further and offering to talk to her elementary school class about solar power.

“We were having a Career Fair and Chad talked to our students about his career as a ‘solar consultant’,” she said. “He was a natural with the children and soon had them eagerly asking questions and interested in the whole solar-energy issue.”

She said she was happily surprised at Bonterra’s total commitment to educating the public about green energy and providing quality products and service.

“Even though I only needed nine panels, Bonterra made me feel like a million-dollar client,” she said.
