German solar and battery supplier SMA Solar said its order backlog reached about €1.75 billion at the end of June, a 50% jump from a year earlier. The company attributes the surge to rising electricity demand from data centers and artificial intelligence, which is pushing utilities and businesses to invest in flexible energy storage.
The backlog figure, which represents orders booked but not yet delivered, is a key indicator of future revenue. A 50% increase suggests that demand for SMA's inverters and storage systems is accelerating, even as the broader solar market faces headwinds from high interest rates and policy uncertainty in some regions.
Why AI is changing the energy picture
Data centers, especially those powering AI applications, consume enormous amounts of electricity. As tech giants expand their computing infrastructure, utilities are scrambling to secure reliable power. Solar and battery storage offer a way to add capacity quickly without waiting years for new gas plants or grid upgrades.
Flexible storage systems, like those SMA produces, allow operators to store excess solar power during the day and release it when demand peaks. This flexibility is becoming increasingly valuable as data centers run around the clock and grid operators need to balance supply and demand in real time.
The trend is not unique to SMA. Across the industry, companies that provide energy storage and grid-balancing equipment are seeing stronger order books. The boom in data center construction is creating a parallel boom in the equipment needed to power them.
What the backlog means for SMA
An order backlog of €1.75 billion gives SMA good visibility into its revenue for the coming quarters. For investors, a rising backlog is often seen as a positive sign, as it reduces uncertainty about future sales. However, it also means the company must manage production and supply chains carefully to convert those orders into delivered products and recognized revenue.
SMA has been through ups and downs in recent years, facing competition from cheaper Asian rivals and a slowdown in some European solar markets. The current strength in storage demand could help offset weakness elsewhere.
The company's focus on flexible storage aligns with a broader shift in the energy industry. As more renewable energy comes online, the need for storage and grid services grows. This is a structural trend that could support demand for years, not just a short-term spike.
What it means for investors
For everyday investors, SMA's news is a reminder that the energy transition is not just about solar panels on rooftops. The infrastructure behind renewable energy—batteries, inverters, and grid software—is a growing market in its own right.
Investors should note that order backlogs are not the same as profits. SMA still needs to execute on those orders, and margins can be squeezed by rising material costs or logistics issues. But a 50% jump in backlog is a strong signal that demand is real and growing.
The AI-driven demand for electricity is a theme that extends beyond SMA. Companies that provide power infrastructure, from data center power deals to grid equipment, are likely to benefit. However, investors should be selective and consider valuations, as some of these stocks have already rallied on the AI narrative.
For those looking at European markets, SMA's news comes as German inflation has ticked up, which could influence interest rates and, in turn, the cost of financing large energy projects. Higher rates can make capital-intensive projects like solar farms and storage facilities more expensive, so the interest rate environment remains a key factor to watch.
Overall, SMA's order backlog is a positive indicator for the company and for the broader energy storage sector. It suggests that the shift toward flexible, AI-ready power systems is gaining momentum, and that companies positioned in this niche could see sustained demand.
As always, investors should do their own research and consider how this fits into their overall portfolio. The energy transition is a long-term trend, but individual companies can face volatility along the way.
