24-kW Home Solar: Yep, Big System

Twenty-four kilowatts is a whole lot of installed capacity for a single home, but that’s the size of the solar power system recently installed at the residence of Carl Harberger – a sustainable building designer in Chatsworth, Calif. And United Solar would like you to know that it manufactured each and every one of the 259 flexible solar panels used in this installation, identified as one of the largest known residential solar power systems in the world. (But not nearly as large as this one.)

The installation, which was completed by ADR Solar Solutions in July, will power not only Harberger’s lighting, electronics and air conditioning, but also home systems that are typically powered by natural gas, such as heat. This will cut the home’s carbon footprint considerably, even in sunny California, as the home totals 6,000 square feet.

Harberger chose United Solar‘s lightweight Uni-Solar panels, in part, because they are flexible and nonpenetrating, and therefore worked with the curved rooftop surface of his house. Rebates offered by the Los Angeles Department of Water & Power as well as federal tax credits helped to sweeten the deal.

For these reasons, apparently, Uni-Solar was the only manufacturer considered for the job. Nancy Palmer, ADR’s manager of sales and marketing, said that not only are the panels working as anticipated, but they are “a beautiful addition to the design of this state-of-the-art home.”

    Solar is ONE area Federal help is needed.nnWhen transistors were first invented they cost around $1 a transistor in 1950 money or around $20 today. A typical home computer contains a couple of billion transistors and I doubt any of you are reading this trivial mumbo on a $20 billion computer.u00a0nnPrices started high and came down. The same will happen with solar given a chance.nnThe problem for small businesses is capital and staying power through the startup phases and maybe in the case of some recent politically fumbled houses of cards greed got carried away, but solar IS a real possibility for getting rid of the power company and big oil. Wait that is probably why is gets such a bad rap in the press…
