The Power Wall comprises  a 3kw inverter and a 2.56kwh Lithium battery which installs in a townhouse in 2 hours.

Our electrician (or yours) will install the PowerWall next to your db board, much like a prepaid meter. He will attach the PowerWall to your lighting circuits for your entire house  and the plugs of your choice. ( Your kitchen appliances and your Tv plug would be my first prize). 

NOTE : The PowerWall is not suited to heaters and geysers, they simply use too much power.  

If you do your cooking and heating by gas and depend on the patches of power between loadshedding  to heat your geyser, PowerWall will enable you to live you life pretty normally.

How long does the Power last?

The PowerWall will keep your lights, PC and TV, fridge and kitchen appliances (the occasional cup of tea) going  for about 5 or 6 hours and will recharge automatically in about 1 hour once the power comes back on.

How long will it take to recharge the battery?

An empty battery should recharge in about an hour when the grid power is restored. If you choose to link up Solar Panels to get free electricity, ( we love that) then your recharging time will depend on the sunlight available and the number of panels you have installed. 

SOLAR CHARGING : If you install 2 X 550 W panels, they will take around 2.5 hours to fully charge your PowerWall battery during full sunlight. 

How much will it cost?

At the time of writing this article ( November 2023) , the PowerWall costs R 27 969 plus approximately R 2000 for installation by a qualified electrician. (your electrician or ours) .  

Loadshedding is here to stay, in fact it is going to get worse.

Can we get "The Good Old" days back again? 

Remember the days when you could walk into a room and hit the light switch without thinking "Are we being shed? "

PowerWall will give you instant Backup Power Supply for your home and those days will be back again.

Beat load shedding stress today, order your PowerWall today for under R 30 000 installed.  ( click here for PowerWall )  

Solar Geysers

In addition to electricity generation, solar energy can also be used to heat water through solar geysers.

These systems use the sun's energy to warm water. The hot water is stored in an insulated geyser to stay hot and ensure hot water  after dark and even during load shedding.

Water heating is the major contributor to electrical costs and solar heaters are ideally suited to provide massive cost savings while ensuring a steady supply of hot water to your home .

Harnessing the Wind: Wind Energy for South African Homes

Utilizing South Africa's Wind Resources

While South Africa is renowned for its sunshine, wind-rich regions can benefit from wind energy as an additional or alternative source of power.

 Wind turbines capture the kinetic energy of the wind and convert it into electricity.

For homes in areas with strong and consistent winds, wind energy can be a valuable solution, especially during load shedding.

Advantages of Wind Power

• Load Shedding Resilience: Wind turbines can provide a constant source of electricity, making homes more resilient during load shedding.
• Clean and Renewable: Wind power generates electricity without emitting greenhouse gases, contributing to a greener environment.
• Potential for Earning: Excess energy can be fed back into the grid, potentially earning homeowners income.

The Importance of Energy Storage

Electrical energy storage : Battery Types and Their Uses

1. Lead-Acid Batteries: These traditional batteries are cost-effective and are often used in off-grid and backup power systems. However, they have a limited lifespan and require regular maintenance.
2. Lithium-Ion Batteries: Lithium-ion batteries are becoming increasingly popular due to their high energy density, longer lifespan, and low maintenance requirements. They are suitable for both grid-tied and off-grid systems, providing essential backup power during load shedding.
3. Saltwater Batteries: Environmentally friendly saltwater batteries offer safety and longevity, making them a sustainable choice for homes striving to cope with load shedding. Saltwater batteries are new technology and at the time of writing (2023) are not yet commercially available. Salt batteries hold the promise of a lower carbon production footprint, significant cost savings ( salt vs Lithium) and significant increase in enrgy storage capacity. 

Heat energy storage: Hot Water Geysers

Solar water heating systems, often referred to as solar geysers, store energy in the form of hot water.

They work by circulating water through solar collectors, where it is heated by the sun.

This hot water can then be used for various household purposes, including bathing and cleaning, reducing the need for electricity or gas-powered geysers and ensuring access to hot water all through the day. 

The Solar Power Audit: A Vital Step in Load Shedding Preparedness

Before investing in a solar power system for your home , it is essential to conduct a solar power audit. 

This audit involves a thorough assessment of your energy needs, the suitability of your location for solar panels, and the size and type of system required.

Factors such as the availability of sun drenched north facing roof tops are a fantastic asset to a South African home.  

Solar companies often provide this service, helping homeowners make informed decisions about their renewable energy investments and load shedding preparedness.

Solar Power: The Renewable Energy  Source for of our Future 

As South Africa faces the looming challenge of unreliable energy grid supplied by Eskom and its increasing load shedding, the need for alternative energy resources has never been more apparent.

Solar power and wind energy offer viable solutions to combat load shedding and reduce dependence on an unreliable grid.

While wind power plays a role in certain regions, solar power shines as a versatile and accessible option for homeowners across the nation.

In the journey towards renewable energy, remember that there is no one-size-fits-all solution.

Your choice should align with your location, energy needs, and budget.

However, as the future energy crises continues to cast its shadow, solar power emerges as a beacon of hope for a brighter, more sustainable future.

For more information on renewable energy solutions for your home and to explore options for load shedding resilience, consider reaching out to the Renewable Energy Experts in South Africa, a leading provider of solar power and Home Inverters designed to keep your home powered during load shedding.

These FAQs provide valuable insights into renewable energy options and load shedding preparedness in South Africa, helping homeowners make informed decisions about their energy needs.

Escalating Electricity Prices:Another compelling motivation is the steady increase in electricity prices announced by Eskom . South Africans have faced rising utility costs, affecting household budgets and financial stability. Going off the grid offers relief from unpredictable pricing models, allowing homeowners to lock in their energy costs and achieve greater financial certainty over the long term.

Corruption and Inefficiency:The energy sector in South Africa has been marred by corruption and inefficiency, leading to mismanagement and compromised service delivery. Individuals who choose to go off the grid are driven by a desire to escape the grip of a system fraught with challenges and uncertainty. By investing in their own energy solutions, they regain autonomy over their power supply.

Skill Deficiency and Political Challenges:The lack of specialized industry skills and political will within South Africa's energy sector has hindered the development of reliable and sustainable energy sources. This dearth of expertise has contributed to ongoing energy crises, propelling those who seek energy independence to explore off-grid options that put control back into their hands.

Reducing Stress and Enhancing Quality of Life:Beyond the tangible challenges, the emotional toll of load shedding cannot be underestimated. The stress it adds to daily living, studying, and office productivity is considerable. Choosing to go off the grid is a proactive step toward reducing this stress, enhancing overall well-being, and fostering a more stable environment for personal and professional pursuits.

Step 1: Assess Your Energy Needs:The first step toward going off the grid is to understand your energy requirements. Take a closer look at your daily energy consumption by considering the appliances you use, lighting, heating, and cooling needs. This assessment will help you determine the size of the solar system and battery storage necessary to meet your household's energy demands.

Step 2: Solar Panels and Home Solar Solutions:Embracing solar energy is a cornerstone of off-grid living. The number of solar panels you'll need depends on factors like your energy consumption and the efficiency of the panels. A basic calculation involves dividing your daily energy consumption by the average daily output of a solar panel. Reputable providers like Home solar solutions offer customizable packages to suit your needs.

Step 3: Battery Storage Planning:To ensure uninterrupted power supply, you'll need effective battery storage. Calculate the required battery capacity by estimating your energy needs during periods when sunlight isn't available. A smart approach involves storing excess energy generated during the day for nighttime use. This strategy reduces reliance on the grid even during cloudy days.

Step 4: Solar Tax Breaks and Incentives:South Africa acknowledges the importance of renewable energy and offers solar tax breaks and incentives to incentivize its adoption. These incentives can significantly offset the initial investment costs of going off-grid. Investigate available tax benefits and rebates that can make your transition more financially viable. Learn more from informative resources like South Africa Solar tax breaks.

Step 5: Mitigating Load Shedding Challenges:Load shedding, an unfortunate reality in South Africa's electricity landscape, can disrupt daily life. To combat this, incorporate backup power solutions. A portable home inverter demonstration illustrates how these devices keep essential appliances running during power outages. Dependable South Africa inverter and solar energy experts can guide you in selecting the most suitable inverter for your needs.

Conclusion:Going off the electricity grid in South Africa demands careful planning, financial investment, and a dedication to sustainable energy practices. By harnessing solar power, utilizing efficient battery storage, and seeking expert advice, you can achieve energy independence while contributing to a cleaner environment for your community and the generations to come.

This Bussinesstech graph tracks the accumulated blackout time in South Africa for the last 4 years. It is a very good indication of how dire the circumstances are and how bad load shedding has become very quickly.

By the 9th of May, load shedding in 2023 had won the run chase, "with 30 overs remaining"!

By 9 May 2023, we had already caught up to the total blackout time for last year.

When comparing the line for 2020 and 2021, they look quite similar, but the writing was on the wall. 2020 scored a total of  5.2 days, and 2021 scored 7.4 days -That is 42% worse than the year before !!!!

The total days of blackout for 2022 was 34.56, that’s a whopping  4.6 times worse than 2021 !!

In 2023 we reached the 2022 total of 34.56 days by 9 May … its game over!  - Yes, load shedding will continue for the foreseeable future.

2. What has Government done and what are they planning to do about it?

A National State of Disaster was declared by the Minister of Co-operative Governance and Traditional Affairs on 9 February 2023. It remained in place for 2 months. 

Committees were set up, meetings were held, and a minister of electricity was appointed. 

To date, we have not seen any concrete benefits of this national state of disaster.

I am sure the tenderpreneurs clapped their hands in glee during the 2 month window of opportunity, as they could now milk the system under cover of the national emergency - with far fewer inconvenient checks and balances on "emergency" equipment acquisitions.

The National Energy Crisis Committee did not use this time to address  the massively disruptive and expensive cable theft problem. A simple clampdown on scrap metal dealers would have  stopped cable theft in its tracks.

No extra power generating capacity has been added, and the government seems to be doing everything in its power to add red tape as the courts back the Eskom monopoly [Eskom wins recent court battle against the small Free State town, Frankfort. ] in its efforts to stop the private sector from generating its own power.

Since we appointed an Electricity Minister, Mr Ramokgopa, earlier this year - apart from many media appearances, and earning a nice salary, he hasn’t managed to do much about the crisis.

The average capacity of Eskom is 3000 MW less that this time last year. 

3. The 100MW Mozambique Joke!

Recently in the news Mr Ramokgopa was seen shaking hands with his Mozambican counterpart to seal a deal whereby South Africa will be purchasing an additional 100 MW with immediate effect (that’s 0.1 gigawatt) building up to 1 gigawatt later in the year.

To put that into perspective, South Africa has a theoretical capacity of around 54 gigawatts but it is in poor condition, today (19 June 2023)  we only have 25 gigawatts available while today’s peak demand is 29 gigawatts.

This leaves a load shedding shortfall of 4 gigawatts today, so I am sorry to say  Mr Electricity Minister, the 0.1 Gigawatt you organised from our neighbour is not going to help very much!

4 Lack of accountability

The ANC Government simply blames Eskom for not planning properly, the public for using too much electricity. It does not hold the SAP accountable for stopping corruption and cable theft, and the "political hot potato"  - rampant township electricity theft,  continues unchecked.

Every year Eskom seems to supply less electricity and charge more for the service that is getting exponentially worse. They seem to rewarded for poor service rather than held accountable. 

The National Energy Regulator, NERSA granted Eskom a 18.65% price hike in January, and have now approved a 18.49% hike for municipalities.

These  increases for Eskom’s standard tariff customers will be effective from 1 April 2023 and the municipalities increase will apply from 1 July 2023.

5 Corruption

What is evident is that corruption and organised crime is rife, and the government, the SA Police and Eskom lack the will to do anything about it.

The National Energy Crisis Committee undertook amongst other things during the national state of disaster to "Fix Eskom" - with no clear indication of how? 

Committees were set up, a minister of electricity was appointed, but we have not seen any concrete benefits of this national state of disaster.

They did not  address a simple thing such as the cable theft problem - Although a simple clampdown on scrap metal dealers will stop cable theft in its tracks.

Will load shedding continue? 

The answer is a resounding, YES !

What is clear is that we are in the calm before the storm.

The government has run out of ideas, and Eskom's capacity decreasing every year.

Individual homeowners, and businessmen need to make sure life carries on. We need to aim at being independent of the power grid as soon as possible.

The solution for homeowners, businesses, farms, schools etc

Here is a 6 step model to get yourself entirely off the grid.

Each step is designed to build on each other enabling you to go as fast as your budget will allow.  

Step 1 – Keeping your essentials connected and online. 

Much of our work, study, internet and day to day communication requires WIFI internet connectivity, and step one is to secure your WIFI, and provide power to your home workstation though rolling blackouts.   

The affordable Power in a Box  home inverter for R 5999 will give your home office 4 or 5 hours of backup.

Step 2 – Sustained connectivity of your essentials during blackouts.

By adding 200 W Solar panels to your Power in a Box for an additional R3000 per panel, you can use the sun’s energy to power your home office.

In one of those extended 2 or 3 day power blackouts that are becoming all too common, your solar panels will power your office requirements during the day while they simultaneously charge your batteries and leave you with an additional 4 hours of backup -after the sun goes down !

Step 3 – Installed Home Inverter 

The next step would be to connect an inverter into your home grid, directly connected to your house DB board. Your appliances will then operate normally during load shedding events. While the power grid is on, your batteries will automatically recharge. Lithium batteries recharge very quickly, normally within about an hour, ready for the next blackout.  

 A medium sized home will use about 30 KWh per day, but most of that will be used by your geyser. The normal medium sized household consumption (excluding geyser) is aproximately 400W – 700W .

By installing a good quality inverter and battery in your house to power your essential appliance load of say 400W, you can ensure that life goes on pretty much normally during extended hours of load shedding.

A  5 KW inverter with a 3KWh to  5KWh lithium battery is a good place to start.

An appliance load of 400W for 10 hours of backup will require  400 X 10 = 4000 Wh or 4Kwh.  Lithium batteries allow you to use about 80% of the rated battery capacity,  so a 5KWh battery would suffice in this instance.

Your geyser would remain on the power grid, and would be warmed up only when the power grid is functioning. Heat will be stored up in your geyser for when you need it,  so your geyser would function as a “heat battery”.

A fully installed Home Inverter system  together with an Electrical Compliance Certificate (COC) will cost from R68000 – A COC is essential to make sure the installation is done properly and that the installation doesn’t nullify your home insurance policy.

Step 4 – Solar home system 

By adding solar panels to match your installed inverter you can start converting the sun’s energy into useful electricity to run your home.

An added benefit is the huge government incentives designed to encourage the public to invest in renewable energy supplies. Until 1 March 2024, 25% of the cost of your solar panels can be claimed as a tax rebate. 

8 X 550 W Solar panels should provide you with approximately  3000 Watts for 6 hours per day in sunny conditions. That equates to about 18 KWh per day, which is more than the requirements to run the essential appliances of a medium sized home. ( eg  500 W appliance load for 24 hours = 12KWh per day )

Cost of installation of solar panels, inverters and Lithium batteries varies dramatically dependent on the quality of equipment you install and your individual requirements, but you can expect to start at around R 100 000. 

A power audit will establish your individual needs. [Click here to enquire for a system that most resembles your requirements and receive a free power audit.]

Step 5 OFF THE GRID with a Solar System plus Geyser Heat Pump 

If your solar system is well balanced with your current essential appliance load, then you only have to add additional solar power to cover the non essentials like pool pumps and geysers. 

A normal 150 to 200 L geyser uses 9KWh to heat your geyser. It will use about  3KW for 3 hours to heat up your geyser from cold to full temperature of around 65 degrees. [3KW X 3hrs = 9KWh] 

A heat pump works on the same principal as an airconditioner. An air conditioner extracts heat from inside and transfers it outside into the atmosphere.  A heat pump extracts heat from the air outside and transfers it to your geyser.  

A heat pump will cost you R25000 installed and will typically only use 1KW for 3 hours, or 3KWh  per day  to keep you in hot water. 

Your pool pump will use about 1KW and can be set to run during sunlit hours. 2 or 3 extra 500W panels will cover the pool pump load easily.  

Step 6 Completely off the power grid

Completely off the grid is very expensive to achieve as you need to not only provide enough solar for daily consumption and keep your batteries 100%  topped up, but you need to have reserve battery capacity to last during cloudy rainy weather.

Depending on your location, you may have to allow for up to 7 days "rainy day" extra battery capacity or add a diesel/petrol generator to your system.

Power in a Box have an OFF THE GRID solution  starting at around R250 000 

Take back the power!

This article is to be seen as a general guide only, a starting point to help you get your head around the requirements, and costs involved of getting off the power grid and taking back control of your life.

Every household would require a power audit to establish your power requirements and then a system that can grow incrementally can be designed to suit your power needs.

What exactly is the power problem and how can we solve it?

Hoping and wishing that it power supply will go back to normal soon is pure folly. The factors involved are complex and will take time and effort and a lot of money to solve. 

The minister himself is not promising anything.

Eskom's reponse

But why are we facing load shedding in the first place?

The primary factors seem to be Crime, Corruption and Capacity

Crime

Rampant cable theft is costing a fortune and causing outages over and above loadshedding. Pylon theft is now added to the list . Thieves are literally cutting supporting struts off our power pylons resulting in massive failures as pylons collapse like they did in Pretoria east this weekend when 7 pylons collapsed across the highway, effectively stopping all traffic and power.

Surely somebody is buying the copper and pylon struts? Effective policing at every scrap dealer with massive penalties for scrap dealers who are complicit in this crime will surely stop cable and pylon theft in its tracks.

Corruption 

Corruption in Eskom and government has been extensively reported in the media like Carte Blanche, but nobody is being brought to book.

Where there is smoke there is fire, and there seems to be lots of smoke!

Capacity

According to our minister, Eskom is only capable of supplying around 27,000 MW and yet our winter demand is around 37,000 MW . With existing shortages like this, planned maintenance is severely affected resulting in Eskom groping in the dark from one emergency to another. As any engineer will tell you, emergencies are very expensive -and open to massive corruption, as the tender process gets compromised by the urgent nature of the emergency.  

Our situation

Clearly our power problem is complex and unlikely to be solved quickly.

Covid resulted in many people having to adjust to working from home, and now those same people have to adjust to loadshedding.  As a business owner I can testify that It is extremely difficult to run a business when your work-from-home staff  are all being loadshed at different times.

High schools and Universities have also shifted their focus to online work since covid. Before we solved our loadshedding problem at home, my 16 year old son suffered severe stress as he  juggled his online homework assignments with the loadshedding schedule.

Townhouse Dwellers have it especially hard. They cannot use generators and “installing solar” is simply not an option. Stuck in the dark!

The solution

We have a solution to this dilemma, which is a staged approach to loadshed-proofing your home office, your student and your household TV and WIFI connectivity.

Step 1  

Step 1 would be a Power in a Box UPS inverter capable of giving you at least 4 hours backup power. Your inverter battery will be charged by the power grid when it is on, and will then keep the power on for your essentials during loadshedding events.

Step 2

Adding a portable 200W solar panel, would give extra protection from extended blackouts (stage 10 loadshedding or cable theft events). This solar panel could be propped up on a townhouse balcony during an extended blackout or placed in your garden to charge your Inverter battery while it supplies continues power to you.

Then after the sun goes down you will still have 4 hours of power available for the evenings.

Step 2

Purchase a single solar panel sized between 200 and 350 Watts and plug  it directly into your Power in A Box. 5 or 6 hours in full sun is enough to keep your battery charged and supply you with electricity all day. This will take your basic home office/entertainment/student essentials completely off the Grid.
