GOING SOLAR: Understanding The Equipment – The Inverter

In this week’s installment of GOING SOLAR we shall take a look at the POWER INVERTER. The Power inverter, could simply be described as a box of electronics that converts the power from your battery to the power used by your TV and fridge. In reality though these boxes vary greatly in how they achieve […]


GOING SOLAR: Understanding The Equipment – The Solar Battery (Part 3)

In this week’s installment of GOING SOLAR we shall take a last look at the solar or deep discharging battery. Today we are going to take a last look at the battery and then combine what we have so far, the SOLAR PANEL, CHARGE CONTROLLER and BATTERY and size a basic 12 volt DC power system. […]


GOING SOLAR: Understanding The Equipment – The Solar Battery (Part 2)

Last week we started looking at one of the major components of your solar power system, the battery. In summary last week we looked at the types of battery’s available, how they are sized, capacities and their life span. As we continue the discussion around the solar battery this week, we have been asked to […]


GOING SOLAR: Understanding The Equipment – The Solar Battery (part 1)

In our continued journey to understanding GOING SOLAR, in the last weeks we have looked at some of the major components involved in going green. So far we have looked at SOLAR PANELS, and the CHARGE CONTROLLER. This week we take a basic look at the battery. This is a huge topic in itself and […]


GOING SOLAR: Solar Power Design Basics – Solar Charge Controllers

The Article below is a sponsored article with content supplied by Clamore Power. Please see our policy on sponsored stories. In our mission to understand GOING SOLAR, last week we started looking at solar power systems major components. The four major components we are looking at before we design a basic system are the following: Inverter Battery Charge Controller […]


GOING SOLAR: Solar Power Design Basics – Solar Panels

We have looked at the basics of power consumption and energy management. Once you have achieved near perfect energy management through either physical means or by changing to energy efficient equipment, you are ready to GO SOLAR A lot of articles have been written about the components that form the solar powered electric system, view […]


Here is a guide to a more energy efficient home

The Article below is a sponsored article with content supplied by Clamore Power. Please see our policy on sponsored stories. As a scaling up of our understanding of power related issues, let us look at energy management and energy efficiency. Energy Management is the process of monitoring, controlling, and conserving energy in a building. It has a physical and […]


GOING SOLAR: Understanding Electricity And Consumption…

Last week we looked at how relevant knowledge about basic electrical terms such as Direct Current and Alternating Current communicates with our daily lives. My intention with this series is to be as technical friendly as possible so that wherever possible, our book of reference will be the basic textbook or secondary school dictionary. Flowing […]


GOING SOLAR: Understanding Electric Power…

Following my exploratory “Countdown to Alternative Energy” write-ups that I have posted over the last two weeks, (Part 1 & Part 2) a few questions have come through. There have been more enquiries about Solar Power among all the other alternative energy options that are available. That is understandable because we are under the African […]


Energy – The Countdown To Going Alternative Part 2

Image Credit: Upsplash – Rodion Kusaev You have made a decision to utilise alternative energy that is clean and green. Congratulations on making this wise decision. Last week, we focused on how you determine your needs, how to choose the appropriate technology and how to select service providers. Now that you have selected the service providers […]


Energy – The Countdown To Going Alternative Part 1

Image Credit: Upsplash – Rodion Kusaev You have decided you need energy, and it has to be clean and green. Whether it is to save money, backup your grid supply, become energy independent or as a primary source of energy, there are a few facts you need to know and embrace in order to make […]


Saith Technologies : What is the real innovation / invention?

In a recent discussion of Saith Technologies’ “innovations” a raging debate ensured about whether true innovations were indeed exhibited. In the interest of objectivity we go through some of Saith Technologies claims and try to clear some misconceptions.


Tesla’s magic battery might be what Zimbabwe needs

Just over a week ago ZESA’s grid system suffered a catastrophic failure that saw both Hwange and Kariba somehow go offline, leaving the entire country, except Bulawayo and probably a couple of Bigwigs’ houses, in darkness. According to ZESA’s Chief Executive Engineer, Josh Chifamba, the power utility did not know then what caused the outage and […]


Solar Power for Dummies Part 6: Regulators

This is the latest article in the series “Solar Power for Dummies.” As we said in the previous article, the components we have looked at so far are good enough to build a rudimentary solar system, a very crude one that is in many ways dangerous both to you and to itself. One way to […]


Solar Power for dummies Part 2: Getting to know your devices

Now that we have gotten the introduction stuff out of the way its time for you to get acquainted with some of the basics of electricity in general and solar power in particular. I won’t be introducing anything scary, I promise, just the basics you snoozed through during the Physics and Integrated Science lessons. A […]


Solar Power for dummies part 1: Introduction

I am well aware my esteemed colleague has already written a guide on solar power. This guide is different, penned with dummies in mind by a man who is also, when it comes to solar power and electricity in general, a dummy, who has taken a journey in the solar world. It is not a treatise […]


Econet makes social impact investment in wind energy

  Econet Wireless, through subsidiary Econet Solar International has joined other investors in an initiative led by Danish wind energy group Vestas to build small wind power generators across Africa. The programme, called Wind For Prosperity, aims to provide power to millions of people living in rural areas and small towns beyond the reach of […]


Econet introduces new solar power products

Yesterday we attended the launch by Econet of a new solar charger/lantern/radio combo product called the Power Lantern SW015. The product is an improvement of the lantern that was on the market which, according to Econet Services CEO, Darlington Mandivenga, the company sold 400,000 of.


“Every Zimbabwean child should be computer literate” says Zim President
