Dave looks at his 3kW home solar power system after being in operation for 18 months and analyses the results. Original video: https://www.youtube.com/watch?v=VGENVguQQmo Timelapse install video: https://www.youtube.com/watch?v=fQAd7nposJQ How much energy was produced? How does net and gross metering work? What is the payback period? What is solar insolation? The 3kW system uses 12 x 250W LG MonoX panels http://www.solarclarity.nl/wp-content/uploads/2011/09/Data-Sheet-LG-Mono-and-Multi-X-ENG.pdf and an SMA Sunnyboy 3000TL inverter. http://files.sma.de/dl/15330/SB5000TL-21-DAU131211W.pdf Uploading data to PVoutput.org using PVbeancounter and bluetooth from the Sunnyboy inverter.

Part 1 in a series of LTSPICE tutorial videos. In this introduction Dave explains what LTSPICE is and how to do the simplest of the SPICE analysis options - basic DC operating point analysis. Also how to draw basic schematics, display voltages and current on your schematic, and a beginner few traps to avoid. http://www.eevblog.com/forum/blog/eevblog-516-ltspice-tutorial-dc-operating-point-analysis/ EEVblog Main Web Site: http://www.eevblog.com EEVblog Amazon Store: http://astore.amazon.com/eevblogstore-20 Donations: http://www.eevblog.com/donations/ Projects: http://www.eevblog.com/projects/ Electronics Info Wiki: http://www.eevblog.com/wiki/
