Many people are looking for backup power solutions for their homes and businesses to see them through unpredictable and productivity-killing Eskom load shedding and are also fed up with the rocketing costs of electricity that Eskom cannot reliably or affordably supply, says Teresa Settas of the One Energy Group, an off-grid energy specialist.<\/p>\n
“The parlous state of municipalities should also be of great concern, with collapsing infrastructure, non-existent service delivery and rampant cable theft that leaves you without power for extended periods of time, compromising your productivity, safety, security, income and quality of life,” said Settas.<\/p>\n
It\u2019s crucial to consider where the country’s energy future is headed, and what this means for your home and business, she said.<\/p>\n
“Any money spent on an unsuitable backup solution today detracts from your ultimate objective of grid independence and self-sufficiency. Don\u2019t be lured into the many cheap \u2018plug and play\u2019 solutions being punted on the market by drop-and-go shippers who offer no back-up or support in-country, and even less in terms of warranties on their products.”<\/p>\n
Start with a scalable, quality solar PV hybrid solution that takes care of your immediate needs for backup power during load shedding and power failures and allows you to scale up in future to self-generation by adding solar panels and additional batteries if needed, said Settas.<\/p>\n
While you can start initially with your hybrid system configured as a backup solution – inverter and battery only – as budget allows, you will be able to expand with solar panels to generate your own power, providing back-up and saving you a fortune in electricity costs.<\/p>\n
Settas noted that not all inverters offer this scalable functionality.<\/p>\n
H<\/strong>ow you start your journey to greater grid-independence step-by-step<\/strong><\/p>\n An electric geyser accounts for 30-40% of your monthly electricity usage in a typical mid-income home, so this is the most crucial starting point to reducing your daily electricity load, which means you can also buy a smaller and more affordable PV solution.<\/p>\n A 200-litre solar geyser, fully installed is around R27,000<\/strong>. On a R2,500 electricity bill, you\u2019ll save around R750 per month, amortising your outlay in just over three years without taking annual electricity cost increases into account.<\/p>\n As your budget allows, you can add solar panels and additional li-ion batteries to provide you with a full hybrid system for self-generation, electricity savings and battery-backup, said One Energy Group. For purposes of this illustrative exercise, it used a Sunsynk inverter configuration – however, there are also other quality hybrid inverter solutions available, it said.<\/p>\n “Don\u2019t get duped into cheap inverters and outdated lead-acid battery technology and installations as these entry-level products simply don\u2019t offer this scalability or reliability,” said Settas.<\/p>\n Option 1:\u00a0 <\/em><\/strong><\/p>\n Option 2: <\/strong><\/p>\n Option 3: <\/strong><\/p>\n With the advances in solar technology and pricing, you can hedge your electricity costs for the next 20-25 years and secure your supply at less than 50% of current prices that Eskom can supply it, by making savvy investment decisions today, said Settas.<\/p>\n “Avoid at all costs the cheap, quick fixes sold by fly-by-nights who promise you the world with a R10,000 inverter \u2013 if it were that easy and capable of taking you off the grid, everyone would have done it long ago.”<\/p>\n Settas said many unqualified fly-by-nights have popped up with even more questionable tech offerings and sub-standard installation quality.<\/p>\n These are just some of the important considerations that One Energy suggests you look at:<\/p>\n\n
