The Function of Silicon in Solar Systems

Without silicon solar just doesn’t happen – this is primarily because solar cells are made up of silicon that is 100% pure.   Silicon has been an important component of electricity for aeons, with solar technology being created in the 1950s. At present almost all solar cells are made from pure silicon.  What you should know about silicon […]

Deep Cycle Batteries & How They Work

Deep cycle batteries: what role do they play in solar systems? In today’s world of renewable energy deep cycle batteries are synonymous with solar.  These batteries store energy, and this is where chemical reactions occur resulting in electricity. Deep cycle batteries are made to recharge and discharge numerous times, therefore, are not disposable, unlike single–use batteries.   Battery backup is connected to the […]

Battery Backup Systems

Battery backup goes by numerous names – these are UPS, Uninterruptible Power Source, Standby UPS and On-line UPS.   When selecting your backup power systems, whether they are generators (either diesel or petrol), an Uninterruptible Power Supply, alternative power sources such as solar or wind power, or an inverter, backup battery and charger configuration which lasts longer than the average UPS system, each one has a positive and a negative component. Naturally […]

GreenPeace Protests: Harmful Emissions

Greenpeace Africa staged a peaceful protest outside Eskom’s Megawatt headquarters on Tuesday the 20th August, complete with hospital beds and pretend “patients” in the beds highlighting the harmful effects pollution has on the health of individuals and the environment.  Most worrying of all is that Kriel in Mpumalanga is the world’s second–largest sulphur dioxide emission’s hotspot – second place only to Norilsk in Russia!  It […]

Protecting Wind Power Turbines

Wind power turbines need to be appropriately protected against lightning and power surges that could cause untold damage to these structures. South Africans, by and large, think of renewable energy in terms of solar power only. There is a definite increase in businesses and homes installing solar panels for them to become independent from the grid.  Fewer South Africans view wind power as […]

Solar Heating in SA

According to the SABS (South African Bureau of Standards), solar–heated water systems should become the norm and not the exception in South Africa. Collaboration between the South African government and the private sector in the past couple of years has now provided a firm foundation for superior quality, safe locally manufactured geysers which is a cost-effective solution […]

Online and an Offline UPS Systems differences

There are differences between Online and Offline UPS Systems – the big question is – what are they and what are the biggest challenges and advantages that we could face by incorporating these devices to keep our electric up and running all the time. The power utility, Eskom, is constantly in the news and is […]

SA Is Ramping Up Its Green Credentials

South Africa is moving forward by ramping up its green credentials by making a difference through the unpacking of numerous solar–powered projects.  Businesses, individuals and the Government Energy Independent Power Producer Procurement Programme (REIPP) are making a difference together and is well on its way to becoming one of the world’s leaders in renewable energy.  Here are some of the awe-inspiring strides that South Africa has made towards greening […]


THE DIFFERENT KINDS OF UPS SYSTEMS For those not in the know, there are numerous UPS Systems that have been designed to keep electrical devices operating during power outages. The many kinds of UPS offerings could cause much confusion among consumers; therefore, it is advisable to investigate all options these thoroughly to make the right […]


An inverter and a UPS system both supply backup power to electrical devices; however, the primary difference between the two is that the UPS from the main supply to the battery is instantaneous, whereas the supply of power from the inverter to electrical devices will take a few seconds before the power will kick in.
