#BizTrends2019: What to watch out for on the global renewables scene

Simplicity in installation ever more important

Global photovoltaic monocrystalline silicon module prices fell sharply in 2018. I predict continued depressed prices in 2019 at around or even below $0,20/W coming from China. The end result is that the cost for modules become an even smaller part of the total installation cost, which in turn will lead to a different business model.

The potential for profits no longer lies with the module costs, but with logistics, balance of system costs and soft costs like permits and administration. So, the focus will shift to ease of installation and new markets where solar modules are still in the greenfield phase: weak roofs, building integrated photovoltaics etc.

Increased focus on CO2 footprint and energy payback

As solar energy installations spread, there will be an increased focus on its carbon footprint and energy payback. To manufacture energy demanding silicon panels, glass and aluminium frames with dirty coal power is not environmentally friendly. PV suppliers will be increasingly judged on the climate effect of their production processes. The advantage here lies with manufacturers of frame- and glassless thin film solar panels which can carry a carbon footprint of merely 1/10 of silicon panels.

Grid owners control supply for a more efficient grid

In clean energy leading California, new guidelines are introduced for grid owners to communicate with and steer individual inverters to control the supply and reduce pressure on the grid in an efficient way. At the same time, inverters will be required to automatically regulate their output depending on fluctuations in voltage and frequency, which they will be able to do quicker and more effectively than the large central power stations can manage, regardless of technology.

This is good news for everyone as new capital-intensive grids might not be necessary at all. Instead it is about software and communication, but are grid owners acting fast enough? Maybe Google, Apple or Amazon could do it twice as fast, and cheaper? A smart home with a smart grid, maybe the threat to utility companies is in the cloud?

Batteries might do exactly the same thing as smart inverters

Batteries are still expensive, but coming down in price. For the long term, when it comes to residential storage, I predict exactly the same curve and market shift as for PV-panels. From today’s $1,000/kWh I think we will sooner than expected reach $100/kWh. Quality from China will become good enough to dominate the market. This is great news for all consumers. With smart inverters and batteries, for most households the grid could be seen as just a back-up solution.

Government incentives played out their role, but there is need for regulations

In most markets government incentives for investment or feed-in tariffs have played out their roles. With today’s and future prices of PV panels, electricity and battery solutions no incentives are needed. However, to stop grid owners from killing the market, strong government regulations to allow PV connections with limited restrictions are needed, now more than ever.

PPAs and auctions will dominate the constructions of large parks
