With the advent of solar panels and windmills, and our ability to generate and use electrical energy locally without the need for long-range transmission, the world is about to witness transformational changes in energy infrastructure. The use of photovoltaics (PV) as source of direct current (DC) power reduces the cost and improves the reliability of PV system. DC microgrid and nanogrid based on PV and storage can provide sustainable electric power to all human beings in equitable fashion. Bulk volume manufacturing of batteries will lead to cost reduction in a manner similar to the cost reduction experience of PV module manufacturing. Future manufacturing innovations and R & D directions are discussed that can further reduce the cost of PV system. If the current trends of PV growth continue, we expect PV electricity cost with storage to reach $0.02 per kWh in the next 8-10 years.

The power sector is about to undergo a major disruptive transformation. In this paper, we have discussed the best possible energy solution for addressing the challenges of climate change and eradication of energy poverty. This paper focusses on the decentralized power generation, storage and distribution through photovoltaics and lithium batteries. It encompasses the need for local direct current (DC) power through the factors driving this change. The importance of local DC power in the transportation sector is also established. Finally, we conclude with data bolstering our argument towards the paradigm shift in the power network.
