Mark Byington is an electrical engineer with 25 years of experience in the Silicon Valley. Founded in 2003, his company Cobalt Power Systems, Inc. specializes in designing and installing photovoltaic (solar electric or PV) systems for homeowners and businesses.
PV systems are both friendly to the environment and a great financial investment. PV systems generate clean power from natural sunlight and replace power generated from non-renewable sources such as fossil fuels. By spinning your electric meter backwards during peak time, you can actually sell power to the utility at twice the rate that you buy it back at night and on weekends. Cobalt Power will show you how.
Each PV system is designed by an experienced electrical engineer. The design is optimized for the specific needs of the customer, including physical site dimensions, orientation, tilt angle, electricity consumption, and budget. Only the finest materials are used in the installation of each system, including all stainless steel hardware, high temperature polyurethane roof sealant, oversized wire for low power loss, and proven solar panels and inverters with the best warranty in the business.
"99% customer satisfaction isn't good enough for us. We aim for nothing less than 100%. From the initial estimate through installation and follow-up, we stay focused on the customer's needs. Since most of our business comes from customer referrals, we feel that we are achieving our goal."

"I liked their customer service. They were friendly. I liked the way they explained, in layman's terms, the complexities of the solar system. They were extremely fast with scheduling, and they did everything the way they said they would do it."
"They were very clear about what they were quoting and their explanations. They did the installation in less time than they said it would be, and their system performed to my expectation."
