Solar energy in South Africa is abundant and cheaper than grid electricity (Eskom / municipal) thanks to the excellent yields available. There are various options for solar solutions such as grid-tie (using solar instead of grid-sourced energy), net metering (selling solar energy to the grid) and hybrids (incorporating batteries). Solar modules (panels) can be installed on roofs, ground-mounted or incorporated into carport structures. Batteries offer an effective way of providing emergency, back-up energy when the grid fails.
Renewable investment analytics are designed to ensure that the best decisions are made on investments in solar systems. Solar systems must be designed and installed to optimise performance and returns. Investments in solar systems, which can be expected to last 20+ years, should be supported and evaluated using reliable, objective data. Energy storage analytics are similarly central when considering batteries as a viable solution for energy security.
The analytics use relevant financial and technical parameters (site-specific solar yield, optimised system design, tariff, energy cost escalation, discount rates, capital / operational costs) to model the investment and provide key decision-making metrics such as energy savings, return on investment, payback period and cash flows. These analytics are an indispensable aide to making the business case for renewables clear and logical.
