With the ever-increasing demand of electricity both domestic and commercial in South Africa, Eskom has taken a strain. Load shedding has become a household term. The future of electricity generation in South Africa lies in producing your own solar energy during the day and storing it in a battery bank to be used at night. With the growth in the number of solar power storage solution technologies available in South Africa. Each one functions in a slightly different way, but the basic principle is the same. A hybrid solar system is generally comprised of a battery bank (utilizing a technology such as standard-issue lead-acid or the increasingly affordable lithium-ion) and a Hybrid inverter that can manage power in accordance with programming.
When you’re investing in a solar system, one of the questions you are probably going to ask is “What happens when the grid fails?”
A hybrid solar system is freeing, as it allows much more independence from your power company. It basically combines the best features of grid-tied solar and off-grid solar. A hybrid solar system remains connected to the grid and uses solar batteries to store excess solar power for when it is needed, such as in the evening or on a rainy day. Hybrid solar is by far the most popular solar storage set-up as it is much cheaper and requires far less storage capacity compared to off-grid systems, plus it has the ability to use the power grid as a back-up when needed. This delivers the additional benefit of allowing you to store the electricity that your solar power system generates throughout the day in batteries, so that you may use this stored electricity at a later time such as night times. Hybrid Solar is an attractive and affordable option for both households and businesses to lower their utility bills and move towards energy independence.
In a hybrid solar system, solar power is first fed into the home, and then excess solar power is used to charge the batteries during the daytime generating period. Power from the batteries is then used at night when the solar system has turned off.
Hybrid solar systems generate power in the same way as a common grid-tie solar system but use special hybrid inverters and batteries to store energy for later use. This ability to store energy enables most hybrid systems to also operate as a backup power supply during a blackout, similar to a UPS system.
The hybrid solar systems will eliminate the need to draw much, if any electricity, from the grid. At Milec Solar the future is already here. Our years of experience and expertise ensures reliable battery backup and hybrid solar system designs which will create clean, low-cost electricity for many years to come. Hybrids systems can include backup systems, which continue to function when the grid is down, as well as systems that will not work when the grid is down.
