What happens if I install solar panels on my roof top today and after a couple years a more advanced technology comes in with panels with panels having much higher efficiency? Not sure if it is practical or not, but I think it would be better if the companies provides some kind of scheme to upgrade the panels at subsidized price if something better comes up.
A nice briefing on the solar panels present cost,energy efficiency,cost of solar power,life time reports of various panels installed at hot and chill places, and finally on the micro inverter approach.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
