RenCell Offering to school

Rencell will fund the development and maintenance of Renewable Energy Assets. The school would simply continue paying for the electricity it continues to use while enjoying energy security during load shedding or general power failures.

Our solutions are endlessly customisable ensuring tailored solutions for each school’s unique needs.

RenCell Introduction

Rencell is a Section 12J registered VCC that specialises in raising capital to fund the development of renewable energy assets. Rencell funds the development of these assets situated on the property of its customers who enter into power purchase agreements or asset rental agreements governing the use of the solar system and battery system. Rencell was approached by UTS to tailor a product offering to schools allowing the schools to fund their own renewable energy assets through the parents of the pupils attending the school.

This solution is to reduce the school’s monthly electrical cost while earning the parents a significant yield on their investment into the ringfenced investment into Rencell.

RenCell Offering

Rencell would raise the capital required to fund the development of the Renewable Energy Asset at a particular school by offering a ring fenced investment to the parents of the pupils attending that school. The parents who choose to invest in this offering would be able to deduct 100% of their investment from their taxable income further enhancing the yield of their investment. Through the innovative debt leverage, corporate structuring and implementation of tax deductions the school would have access to the most desirable of alternative energy solutions at no additional cost over existing electrical spend while earning investors returns in excess of 20% IRR.


The school’s electrical expense would be earning parents who invested in the opportunity a yield rather than this being paid to an entity yielding no benefit to the parents. will fund the development and maintenance of Renewable Energy Assets.
The school would simply continue paying for the electricity it continues to use while enjoying energy security during load shedding or general power failures.

Our solutions are endlessly customisable ensuring tailored solutions for each school’s unique needs.

Key Benefits To The School

Schools that adopt this approach will be able to enjoy all the benefits associated with renewable energy technology without the substantial capital outlay required. Schools will have students in classes for more hours than comparative schools as they are unaffected by load shedding or general power failures.

Schools will have enough security of electrical supply and internet connectivity to justify adopting and investing in digital learning technologies ensuring the highest quality of education possible to give to students without sacrificing educational time during load shedding or general power failures. Schools will enough uninterrupted security as no loss of power to security systems means the school is never vulnerable and immediately identified as an undesirable target by criminals.

As recent data has indicated private schools are losing pupils to emigration, or enrolment in cheaper schools. As this market space continues to become more competitive this kind of technology could be the kingmaker when it comes to parents deciding on their child’s school.

Keeping education as unreliant on electricity as possible

This is the most cost-effective solution in the short term but will seriously impact the selection of study material in the near future and leave students inexperienced in the use of digital study material as they progress through the education system. This would still leave the issues around security, sanitation and lack of ability to power existing devices dependent on electricity.

This alternative has been widely elected thus far but as more schools switch to digital learning all schools will be forced to follow suit as such this is unsustainable and irresponsible.

Diesel Generator to provide backup power

This alternative while not the most costly upfront will prove far more costly down the line as electricity generated from this source is the most costly of all the alternatives. This alternative also has the most health concerns with diesel fumes known to have side effects as well as the noise generated disrupting learning and impeding students abilities to hear their teachers.

The alternative also truly unsustainable as it requires large volumes of fuel and regular maintenance, the systems are designed to operate as a backup only and if they are required to run continuously for weeks on end major breakdowns will occur using conventional generators. The large volumes of fuel will prove an issue during load shedding as the severe recent load-shedding strained diesel delivery services with many generators running dry during this period.

Backup Batteries

This alternative has the least impactful to students but comes with the disadvantage of a limited supply of energy as the grid has to return for a significant period of time for the batteries to be able to recharge themselves over 12-18 hours.

Battery integration into the energy supply allows for seamless switching between energy sources as the grid fails the end users would have no idea as the batteries seamlessly takeover. The invertors that form part of this solution would act as a UPS for the entire school meeting all electrical equipment on school property would be fed clean power prolonging the expected lives and reducing the need for costly maintenance.

Grid Tied Solar

This alternative while cost saving in the near term does not provide any backup energy during power failures, this system can run in tandem with a conventional diesel generator resulting in significant fuel savings as the solar system takes a significant portion of the load from the generator. The system would require very little in terms of integration into the electrical reticulation of the school.

The system would, however, be dependent on another supply to create a grid which it would then supply the school’s load from; this grid can be the national grid or a diesel generator.

Hybrid Solar

This alternative has all the benefits of the previously mentioned systems as it incorporates batteries, onsite energy production and the capacity to continuously recharge the batteries. These batteries would be similar to those used in a backup only solution, but lithium-based batteries would be used in this application. The system would be able to operate without a grid for years with no need for accelerated maintenance or near-daily fuel deliveries.

This system would operate cost-effectively from day one saving the school money on the electricity it does consume while providing seamless backup when power failures are experienced.

How dependent schools are on a stable supply of
electricity to power their needs

Recent widespread stage 4 load shedding demonstrated how ill-prepared major institutions and infrastructure is and will continue to be once this becomes commonplace. Water supply interruptions as extended and frequent power failures left pumps unable to pump enough water to meet demand, this is a critical issue for schools where water is critical for sanitation.

Interruptions in cellular and internet services as backup batteries could not be charged fast enough in preparation for the next power failure cycle. Massive breaches in security as false alarms from drained batteries keep alarmed companies occupied giving criminals reliable and predictable windows when security systems would be ineffective or off. Power outages left schools unable to teach students as 67% of the school day would be lost if a 4-hour power failure would leave only 2 hours of a 6 hour school day to cover the work expected to have been done that day.

All of the above are services critical to any educational institution being able to provide a world class education in a safe environment the loss of even one of these would be detrimental; the loss of all would and has proven to be catastrophic to the education system.

Educational institutions in South Africa are under mounting pressure to accelerate the adoption of digital learning or face being left behind during the current 4th industrial revolution. The adoption of this technology is becoming ever more costly and dependent on reliable high bandwidth stable internet connections, stable electrical supply and networking across the school.

The recent and ever-growing risk of rotational blackouts, above inflation rise in costs, lower enrolment numbers and growing security risk has to lead to concerns with the adoption of these technologies as their cost, dependence on electrical and networking infrastructure and risk of theft has made these technologies undesirable. The adoption and widespread use of these technologies can no longer be postponed as educational institutions risk falling behind as the development and use of these technologies continues to accelerate worldwide.
