- Sun, 28 Mar 2010 -- NanoSolar Update
Flashback a year or so, and I was extremely excited about a new technology that had emerged on the solar scene: Screen-printed solar panels that were nearly as efficient as poly-crystalline cells at a fraction of the cost. Due to the normal trade-secrets and monopolization of design, things have been progressing slowly since the first [...] - Tue, 28 Jul 2009 -- Evacuated Tube Solar Thermal Collectors
Here is my take and understanding on a Solar Thermal technology that had evaded my attention until now. With upwards of 35% efficiencies and relatively low cost, it appears to be the best way to harness the sun's power and lessen your dependence on your local utilities. - Tue, 28 Apr 2009 -- Solar tidbits
My home-made solar panels were finally set up today to do a test, and behold! In full sun I achieved 430 mA. Not great, the cells were rated at 875 in perfect conditions. Remember, however, that I used less than ideal methods of soldering and attaching the cells to the back board. As a result, [...] - Tue, 31 Mar 2009 -- New Section
I’ve revamped the update method for the site, to make fuller use of my blog and its publishing capability. All main group pages will now have news feeds driven from the blog. - Sat, 21 Mar 2009 -- Conservationists Against Solar
Conservationists are attempting to block green energy installations due to their environmental impact. - Sun, 08 Mar 2009 -- Mini-solar update
I haven’t gotten the 875 mA cells in yet, so no new 10W panel, however I did remove all the unnecessary LED’s from the system, and can now get a minimal charge started as the sun comes up. Essentially, I had to overcome 20mA of wasted energy through LED’s before sending anything to the battery. [...]
