You have likely been told many times different facts about solar energy. Of course, it is hard to know which facts about solar energy are actually "facts" and which are more like opinions.This information is going to relay to you many of the top facts about solar energy. It will delve into not just positive facts about solar energy, but negative ones, as well. Do you want? Let's begin:Facts about solar energy (in no particular order):* Solar...more
When mobile phones started to become popular in the early 1990s, they were devices that were particularly cumbersome and were capable of carrying out nothing more than a straightforward phone call.Over the past two decades, however, mobile phones have evolved in such a way that they are, to all intents and purposes, mini computers.Allowing you to do everything from watch HD films to browse the internet, these types of mobiles phones - known as...more
There comes a time when it is necessary to revamp a room or office space in order to freshen up the environment and create a new and different atmosphere within the space. This can often be a lengthy process as we are accustomed to the way it looks now, so to change it is often a difficult and tricky process. The last thing we want to do is spoil the existing atmosphere if it is already working, but at the same time we can't stand still and as humans we thrive on changes that we have control over.So, how do we approach such a difficult process and how do we ensure that we make changes that are beneficial to the home or office environment? Well, there are a few things to consider before you even start the ball rolling. The first of which is to try and decide how you want to change the room or space. What is the end result you are looking to achieve? Is it a total overhaul you need or are you looking to make small changes that will make a big difference aesthetically?After you have answered this question then you will be in a good position to get the whole process started in earnest. You may have decided that a simple paint job can do the trick and lift the room. This is often the...more

Understanding & Using Solar DC-AC Inverters Part 3Capacitive loadingActually there.s a different kind of problem with many kinds of fluorescent lightassembly: not so much inductive loading, but capacitive loading.Although a standard fluoro light assembly represents a very inductive load dueto its ballast choke, most are designed to be operated from standard AC mainspower. As a result they.re often provided with a shunt capacitor designed tocorrect their power factor when they.re connected to the mains and driven with a50Hz sinewave.The problem is that when these lights are connected to a DC-AC inverter with its.modified sinewave. output, rich in harmonics, the shunt capacitor doesn.t just.correct. the power factor, but drastically over corrects . because its impedanceis much lower at the harmonic frequencies. As a result, the fluoro assemblydraws a heavily capacitive load current, and can easily overload the inverter.In cases where fluorescent lights must be run from an inverter, and the lights arenot going to be run from the mains again, usually the best solution is to eitherremove their power factor correction capacitors altogether or replace them with amuch smaller value.Auto...more
