In June, the OpenSolar team embarked on a road trip across the southwestern United States along fabled Route 66.  The route takes you through the epicenter of solar thermal power plants in the Mojave desert region, including the original SEGS plants at Kramer Junction, Harper Lake and Daggett.      



Central station solar thermal is hot these days and there are gigawatts of Mojave desert solar projects signed up and currently under development.  But the SEGS plants at Kramer Junction and Harper Lake are still "collectively known as the world's largest solar site with a generating capability of 310 megawatts". 

The nine original plants were built by solar power pioneer LUZ from 1984-1991 and "have generated more than 11,000 gigawatt-hours and produced more than 1.7 billion dollars of revenue over the past 22 years."  The plants remain profitable today but the business climate for solar in the US has not always been so kind.  Luz filed for bankruptcy in 1991.



Florida based FPL Energy currently operates the plants and offers public tours once a week.  Drop in unannounced though and you'll have to get creative if you want to see much.  Meanwhile, Luz has re-emerged from the dead as Luz 2 - aka Brightsource Energy and are currently developing a bigger and better concentrated solar thermal plant nearby.

For the solar enthusiast, visiting these original SEGS plants feels like a religious pilgrimage.  The plants are quiet, clean and beautiful.  This is Erin Brockovich country so the abandoned, arid desert conditions are a little creepy, but seeing these solar power plants in person is inspiring.  You will be astounded by how much solar potential we have in the southwest United States.  Some argue that the large footprint of a solar power plant makes it inefficient in terms of land usage, but the reality is that there is NOTHING here.  It's an endless, barren land that few organisms can survive in amidst the harsh climate. 

Covering the entire Mojave desert region with massive solar plants would be a boon to the dismal local desert economy and would establish the United States as the world leader of solar power.  It could ultimately help save the rest of us from ourselves, but if the licensing history of SEGS (3-7,8,9-10,11-12), or recently proposed initiatives to stop solar development in the Mojave are any indication - we may end up spinning our wheels into oblivion. 

With so much at stake, well meaning citizens and politicians in the southwestern United States need to take a hard look at themselves and their own hypocrisy.  Is saving a few desert tortoises or "keeping Route 66 looking like it did in the 1930s" really worth the millions of casualties and displaced people around the world that we are sure to encounter if we don't act soon to address global climate change?

mapping the California Solar Initiative

Solar Installations in CaliforniaToday we released an update to our California Solar Initiative data navigator.  The new version is much more efficient and provides additional ways for you to visualize the residential solar industry in Calfornia.

Some of the biggest changes include the introduction of treemaps to navigate the vendor landscape and heatmaps to see where they're active across the state. 

The treemaps allow you to see the dominant solar companies in California in a single glance.  You can browse by the most popular installers, sellers, manufacturers, models or cities.  Click on a company at any time to see all of its completed solar installations that received funding through CSI since 2007.

We hope that you'll find this interesting information.  This week, our development team is hard at work getting our initial solar platform release ready for our alpha testers to take a spin next week.  If you're interested in seeing what it's all about - direct message @opensolar and I can send you an invite.

Check out our CSI Browser and let us know what you think!

The extension of federal solar investment tax credits, coupled with state and city rebates are making it easier than ever to go solar these days.  Thinking about taking the plunge?  Would you be interested in seeing a list of solar installations in your area and how much each one cost per installed watt?

Our CSI Browser lets you navigate completed installations that received incentives through the California Solar Initiative from 2007 - 2009.  Solar panel installations doubled in California in 2008 and this tool helps show you how it happened.

One of the most interesting features is the price per watt graph. Price per watt is a key metric for measuring the real cost of an installation - yet as the CSI Browser shows, actual price per watt values vary greatly from one PV system to the next.

screenshots_csi.jpgIn the above graph we can see the price per watt for completed CSI installations registered as "Self-Install" over the past two years.  The values range from $3 to $13, with the average price for a self install hovering around $8/watt ($6/watt after the CSI incentive).

csi_screenshot1.jpgWhen you click on an item in the list, or a node on the graph - it will pull up information about that particular installation.

The description includes the system size, total cost, the CSI incentive payment and a description of the system - who it was installed by and what solar components it uses.  You can filter the installation results by clicking on the installer, PV module, inverter or manufacturer.  Check out the highly fragmented installer business or look up market share for the major solar manufacturers.

The CSI data is not perfect and the browser is a work in progress, but it should give you a sense of what we're up to at Open Solar.  We've got an open platform that we use to gather data about solar installations. Over the next several weeks we'll be introducing new features and functionality which will bring Open Solar to the networks of Facebook, Yahoo!, MySpace, Google and LinkedIn.

Information like average price per watt by installer make for interesting data points, but the real story behind every solar installation is a human one.  The goal of our Open Solar social app is to make it extraordinarily easy for users to capture that story and share it with friends and solar fans alike. 

Try the CSI Browser - and tell us what you think.

solar living center

Yesterday we checked out the Solar Living Center in Hopland, CA.  I've been there before but always enjoy stopping by.  The place is really nice and the staff is very friendly.



It was my original visit to this place that inspired me to buy shares of Gaiam.  Those shares doubled in value quickly and I was feeling pretty fantastic about the whole thing.  Alas, then the real goods IPO split off the solar business and the Bush Depression did the rest.  Things did not fare so well for GAIA last year.



But the low stock price belies all the good, educational, family oriented solar fun that goes on here.  The Solar Living Institute offers a series of educational workshops, runs a popular internship program and hosts the popular renewable energy SolFest festival each year gathering visionary speakers, musicians, performers and concerned citizens alike.  Just a two hour drive from San Francisco, you'll be inspired by their example of solar living   Check it out!

Introducing Open Solar

| 44 Comments | No TrackBacks
UCBerkeley-sun-portrait.jpgWelcome to Open Solar.  The idea for this project originally began almost 18 months ago when the city of Berkeley started talking about an innovative financing program which would allow residents to install solar panels and pay for them over 20 years through their municipal taxes.  This would effectively eliminate one of the major obstacles of "going solar" - the high upfront costs.  The pilot phase of the plan has now been implemented and could eventually become a model for other municipalities across the United States and beyond.

But not everybody lives in Berkeley, and even with similar financing plans available, the task of buying solar panels, getting them installed and up and running is daunting for most people.  There are so many vendors, so many products and so many government programs to learn about.  The industry has really just begun to emerge from its infancy.  We need a resource that allows us to learn and share from each other. 

Whenever I buy a book these days, I make my selection based upon the reviews I find online at places like Amazon.com.   When I buy a new TV or home theater system - the customer ratings and reviews have an enormous impact on what product I end up purchasing.  Even when we bought our car a couple years ago - it was the positive customer feedback it had received that gave me the confidence to sign that loan agreement. 

No such resource currently exists for those interested in going solar.  Many companies have emerged which will help guide you through the process.  They can help answer questions you have, suggest a type of system based upon where you live and refer you to a respected installation company in your area.  But what I'm looking for is people.  People who have already gone solar.  I want to hear their story.  I'm really interested in learning everything about their experience with solar power. 

Open Solar will help connect people together so they can share information about products and vendors.  We're interested in any and all feedback from solar consumers, businesses and enthusiasts.  We're going to make it really easy to access the site from Facebook or MySpace, or using a Yahoo!, Google or OpenID account.  Finally, we will share the data we collect via a set of open web service APIs and RSS feeds that anyone can use to better understand the residential solar industry. 

Our core functionality is currently under development, but we'll be blogging about all things solar over the next couple months and keeping you apprised of all our developments.

Stay tuned and we look forward to hearing from you.
