A collection of resources for the photovoltaic educator.
As solar cell manufacturing continues to grow at a record-setting pace, increasing demands are placed on universities to educate students on both the practical and theoretical aspects of photovoltaics. As a truly interdisciplinary field, young professionals must be fluent with the science, engineering, policy, and market dimensions of this technology, in the context of a growing renewable energy economy

The main resource on this site at the present is the PVCDROM:
The site is undergoing a large revamp while we prepare it for multiple languages. You might have seen multiple languages in recent time but the navigation has been shifted to a backup site while we complete the navigation. The new site will be available in arly April.
We get a lot of traffic to the site and a large amount of spam postings. Most of them get filtered out but on March 5 a few more evaded the spam filter than usual. We had to delete many of the accounts and messages created on that day. We apologize if you had a legitimate account deleted or we missed your feedback message. As far as we know it would only be one or two posts. We seem to be back to normal so try to repost.
On the page "Calculation of Solar Insolation" the second graph down on module tilt was correctly showing the data on the screen. However, the button "Show Data" was reading the data from the third graph. It is now fixed so the data table matches the displayed graph.
When we started doing an electronic book on photovoltaics web browsers had very limited capabilities. Java was all the latest technology and so we did the interactive graphs by using a Java plugin. Jeff Cotter did all the coding and the interactive graphs were far ahead of anything else available.
In the intervening years, web browsers became much more powerful and standard compliant making sophisticated graphics possible. Meanwhile Java exhibited an increasing number of vulnerabilities and we see more and more people visiting the website without Java. We estimate a quarter of people have Java disabled or no installation at all.
Due to these two trends we converted all the Java graphs to HTML5. They are viewable on all the major browsers and without any plugin. They even work on the iPad. Jeff wrote such great structed code that the conversion was straight forward and the new frame work is entitled JeffGraph. It is unusual to be able to be use someone elses code but in this case we used it in a different language.
The only disadvantage is that it does not work in Internet Explorer 8 on Windows XP. Those users will have to use Chrome or Firefox to be able to see the new graphs. We estimate that this is less than 10 % of users and it is declining all the time.
We hope everyone enjoys the simplicity of the new JeffGraphs and we welcom suggestions for new graphs.

You can also comment on pages and the comments are viewable by everyone. You must be logged in leave a comment and we delete messages that are spam or totally off topic. The page comments only open in late April 2013 so only a few pages have comments.
The pveducation website is now on a hew host to cope with the increasing demand. Page load times are now considerably faster.
