The markets for storage and inverters are evolving along with the overall solar power system.
As the market for solar power expands, so will those for inverters and batteries.
I read a useful article on the intersection of solar, batteries and inverters at Solar Power World. This article says that “Optimizing storage technologies with inverters during system design will be critical for companies looking to compete in what may soon become a $2.8 billion market.”
According to the article, when designing a solar-with-storage system, there are far more design factors to consider than with a grid-tied solar project. Can’t deny that, of course!
Some of these design challenges and intricacies arise from the need to calibrate battery voltage and capacity, battery chemistry, AC output voltage and phase, average and peak loads and grid-interactivity. Project cost is another major consideration and plays a significant role in figuring out the extent of battery required especially. Though added energy security seems like a no-brainer in most cases, the additional cost of energy storage and corresponding power electronics must be taken into account.
As the article says, the intersection of solar+batteries+inverters is indeed an interesting one and one can expect significant technological developments in this field over the next few years. One can expect new technologies to emerge to improve the ease of installation and increase the functionality, improving the customer’s return on investment and energy independence.
