Annual worldwide revenue from residential energy generation and storage will hit $71.6 billion by the year 2023, up from $52.7 billion in 2014, according to a new report from Navigant Research.

While rooftop solar PV systems will obviously represent a significant portion of said growth, other technologies will certainly factor in as well.

“Rooftop solar PV is just one of the technologies that are transforming the traditional residential power industry,” states Neil Strother, principal research analyst with Navigant Research. “Some of these technologies, such as residential combined heat and power, are in the early stages of market development, while solar panels are more mature. Nonetheless, these energy innovations and attractive financing mechanisms provide residential customers with new options.”

One key driver for this sector, according to the report, is continuing advances in new technologies, such as more efficient energy storage systems (ESSs). These advances, along with government subsidies for ESSs, often in the form of feed-in tariffs, are enabling the combination of rooftop solar PV systems and residential energy storage in order to collect and store energy for use when sunlight is unavailable or there is a power outage.

The report, “Residential Energy Innovations”, examines the market for residential generation and storage technologies and discusses how they are reshaping the future of the residential power industry. It analyzes the key market drivers and inhibitors influencing the market, as well as major technology issues. Global market forecasts, segmented by region and category – solar PV, energy storage, electric vehicles (EVs), and residential combined heat and power – extend through 2023. The report also provides profiles of established and new industry players and explores policy issues related to residential distributed generation and energy storage technologies.

In related news, the world’s first building integrated solar system that provides both electricity and heat was recently installed at a small house in the inner Sydney suburb of Glebe. The system  works by combining thin-film solar PV and solar thermal technologies into a steel sheet roofing product.

“The top layer of the roofing product generates electricity in the same way as solar PV modules – although it uses thin film technology for less weight and thickness – while heat is trapped and distributed between the two layers for use in water and space heating.”

Very interesting. I’ll be curious to see the costs of systems like these fall in the coming years, if they do then there will no doubt be a market for them.
