Renewable Energy


The rising cost of electricity coupled with a growing requirement to reduce carbon emissions and operate in a greener, more eco-friendly manner has led many businesses to seek alternate energy solutions.

Solar energy is abundant, clean and pure, and is the ideal solution to these challenges. The vast majority of the South African landscape enjoys annual average solar irradiation levels in excess of 2000 kilowatt hours (kWh) per square metre. This can be harnessed as a valuable source of renewable energy

In addition to producing a sustainable supply of clean energy, investment in solar electricity production technology will make businesses less dependent on utility or grid-supplied energy. This protects businesses from rising electricity costs, can reduce the impact of power outages and offers ever-improving financial investment returns with payback periods in the medium term.

Jasco Renewable Energy offers a number of photovoltaic (PV) energy production solutions, helping organisations to combat global warming, reduce collective dependence on fossil fuels, and enjoy Carbon Tax savings from 2016 onwards.

Industry Challenges

The majority of businesses are totally dependent on utility grid supply. This introduces issues around the security of supply, as on-going incidents of load shedding are expected to continue for the foreseeable future.

Electricity prices are set to increase year-on-year, again for the foreseeable future. These price increases are also expected to exceed inflation by a significant margin, resulting in a major impact on on-going electricity costs.

South African businesses need to reduce their dependency on utility power and hedge against future grid supply price increases. In addition they need to reduce carbon footprint and contribute to a greener, more energy efficient country.    


Jasco Renewable Energy specialises in the engineering and implementation of PV production technology.  We assist Customers with investment decision-making by conducting detailed energy consumption, energy economics and projected lifecycle expenditure analysis.  Customers are presented with comprehensive business cases outlining return on investment and payback periods associated with a financial commitment in this renewable and sustainable technology.

We offer a number of solutions:

Grid-tie solutions
These are a common photovoltaic (PV) installation configuration in which electricity is generated by the PV system and routed to customer loads, offsetting the utility electrical demand of a business.  

PV grid-tie solutions offer a financially viable and more certain energy price alternative to utility or grid-supplied energy in the future.

PV with Backup (hybrid) power systems
These incorporate energy storage, usually batteries.  Batteries are charged by the solar array and charge controllers and/or through the utility connection and a bi-directional inverter. When there are utility power fluctuations such as load shedding or unplanned outages, the batteries and inverter provide continuous AC power to critical loads.

Hybrid PV systems with energy storage capability are more expensive but are an ideal solution to load shedding problems and security of supply concerns.

Off-grid systems
These are completely disconnected from the utility grid.  Off-grid systems typically include a solar array, DC charge controller, batteries, bi-directional inverter and controls. There is also the need to add other fuel generator alternatives for high load applications.  In this configuration, energy is collected and stored to meet all local power requirements. 

Off-grid systems are the most expensive but offer complete independence from the utility grid.


PV renewable energy solutions offer a number of benefits to businesses.

Reduced operating costs to the commercial enterprise:

  • Lower utility bill through reduced energy consumed from the grid.
  • Taxation benefits - Reduced corporate and carbon tax expenses (28% of 50% : 30% : 20% wear & tear allowances and R120 per tCO2e emissions).

Reduced medium- and long-term risks to the entity:

  • Hedge against utility grid price increases. Solar PV is a known ‘fixed’ price alternative source of power.
  • Environmental leadership by reducing carbon intensity, accumulating green leasing options and promotional value.
  • These factors help to improve the net investment value of the building and premises.

Distributed energy generation solutions:

  • Reduce primary (fossil fuel) energy resources required by the utility and contribute towards resolving on-going utility supply constraints and problems.
  • Provide alternative, renewable energy sources to promote sustainable growth of the economy.

Providing security of supply (if hybrid or off-grid solutions are implemented):

  • Hedge against power outages or load shedding
  • Reduced loss of revenue and operating profits during power supply outages.

Possibility to reduced Notified Maximum Demand (if hybrid solutions are implemented):

  • Reduced daytime peak demand can translate into lower peak demand charges and reduced operating costs if well managed.

Completed projects

Jasco Solar Carport

Jasco installed Solar PV Solution at its Head Office in Midrand, Johannesburg. The Solar PV Solution  reduced its maximum demand by 27% and reduced its electrical consumption from the Utility by 33%. 
Both these reductions have resulted in a significant financial savings. As a results of this project Jasco has reduced its carbon emissions by 50%

The vision was to use solar electricity to power much of the Campus energy needs, to cut down on the costs of traditional power, reduce dependency on the national grid, and gain valuable insights into clean energy deployments. An additional upside of this project is that Jasco is able to use their head office as a reference site and showcase in order to better serve clients.
