Cisco administration 101: Learn 10 commands to configure on a new router When it comes to configuring a new Cisco router, much of the configuration depends on what type of router it is as well as the purpose it will serve.

Every administrator has his or her own list of commands they use to configure a router "just right." Here's my list of 10 commands that I think you should configure on every router (in no particular order). After you read through them, post your own favorites in this article's discussion. Configure a login account on the router, and use it on lines I highly recommend configuring a real username and password account on routers and switches.

Solar panel Photovoltaic solar panels absorb sunlight as a source of energy to generate direct current electricity. A photovoltaic (PV) module is a packaged, connected assembly of photovoltaic solar cells available in different voltages and wattages. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. The most common application of solar energy collection outside agriculture is solar water heating systems.[1] Theory and construction[edit] A PV junction box is attached to the back of the solar panel and functions as its output interface. Module electrical connections are made in series to achieve a desired output voltage or in parallel to provide a desired current capability (amperes) of the solar panel or the PV system. Solar panels also use metal frames consisting of racking components, brackets, reflector shapes, and troughs to better support the panel structure.[2] History[edit]
