One solution to ensuring the long-term growth of solar is to deploy solar with energy storage either co-located or as standalone systems. Solar+energy storage provides flexible capacity by both absorbing over-generation midday and discharging it during the evening hours when carbon-free energy is needed.
The need for cost-reduction strategies has been a topic of deep interest and will continue to be one. Nevertheless, the bigger question is: how can we find the sweet spot between profitability and reliability?
2018 witnessed unprecedented records for the economics of solar+storage, demonstrating a variety of value streams and thus making the tale of this marriage all the more compelling.
