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.
DEPENDENCE ON UTILITY SUPPLY
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.
RISING COST OF UTILITY POWER
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.
REDUCING GRID DEPENDENCY
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
We offer a number of 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.
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.
