Renewable energy sources offer clean, inexhaustible and increasingly competitive energy. This differs from fossil fuels principally in diversity, abundance, no greenhouse gas emissions, and potential for use anywhere on the planet. It is common knowledge that both the energy demand and electricity prices in South Africa are steadily on the rise. Figure 1 shows the projected energy mix until year 2050, where installed generation capacity is compared with energy demand. The graph shows a significant contribution by coal-based power stations which will unfortunately reach their lifespan during this period (see Figure 2). In year 2030, there will be an annual shortfall of 84 TWh needed to meet the required 344 TWh. This situation worsens further over the years, thus a signal that alternative sources such as renewable energy are need pronto.
Kurumeng specialises on solar power related interventions, which contributes immensely to the desired sustainable energy future. Once energy efficiency measures are implemented where applicable, Kurumeng then uses the Vela Solaris professional simulation software, i.e., Polysun, for the design, dimensioning and optimizing photovoltaic and solar thermal systems, heat pumps, cogeneration units and combined systems. Clients can upfront gain insight on planning of the entire photovoltaic systems, construction and string plans, as well as geotagged visualizations in 3D and global yield forecasts, amongst other benefits. Consideration is also made for system configuration, e.g., off-grid, grid connected, hybrid, etc., and in line with grid connection regulations.
