Place your bets! Is the solar industry emerging or maturing?

In theory, every emerging industry moves through the stages of the Consolidation Curve (Harvard Business Review, 2002) as it becomes a mature industry. Know where your industry lies on the curve! Each stage requires a different business strategy and focus. Mastering the strategy ultimately allows your company to be one of the top companies in a mature market.

I wanted to pinpoint the solar inverter industry, so I compared it to three characteristics found in each stage of the Consolidation Curve: market share, strategy and finance.

mature or emerging market ?

Stage one: Opening

At one point in time, there were a limited number of inverter companies, but the modern inverter industry has existed since the 1980s with the founding of companies like Xantrex (now Schneider Electric), SMA and Advanced Energy. In 2009 there were at least 100 inverter companies which doubled in 2010 (along with revenues). Despite the sheer number of companies, there were clear market leaders even in 2007.

Inverter companies are no longer defending a first mover advantage, but they do continue to establish barriers to entry. As Jon Sigurdsen said in 2011, “it is easy to make an inverter, [but] it is relatively hard to make a good inverter.” For this reason, not everyone can jump into the inverter market. Companies like Schneider Electric with similar technologies like UPS, AC-DC power supplies, motor drives, etc find it easier to enter the market. Incorporating industry-leading parts like Square D disconnect switches into its grid-tie inverters ensures reliability.

Stage two: Scale

The top three solar inverter companies today control slightly more than the 15-45% characteristic of this stage. That is, globally and in certain countries. Market share actually varies greatly by country. For example, the top three companies owned around 60% of the US market in 2012, but only around 40% of the global market.

Building global scale is critically important in the solar inverter industry. Solar emerged primarily in Europe, but has since moved to the US, South America and Asia. Companies with no footprint in promising countries quickly lose market share. Schneider Electric’s global presence gives it an advantage in this stage.

Stage three: Focus

This stage is perhaps most aligned with the current solar inverter industry. Certainly the top three companies do control between 35-70% of the market and have since at least 2007. Mergers and acquisitions have contributed to market share gain. Schneider Electric acquired Xantrex, Advanced Energy acquired RefuSol, and ABB just announced they will acquire Power One.

Mergers require companies to focus on integration and core businesses. Top inverter companies tout themselves as “bankable” in direct response to weaker companies dropping out of the solar market and leaving customers with unsupported products. Strong companies in this stage emphasize their strength and buy-up or weed-out unprofitable businesses.

Profitability should be focused on in this stage, but there are several major inverter companies in the market today with little to no profits. These companies are acting like they’re in stage one where revenue is more important than profits.

Stage four: Balance and acquisition

We would expect to see recent consolidations in the solar inverter industry resulting in more control for fewer companies. Instead, several top companies have lost market share. The top 10 inverter companies lost 4 percentage points in 2012 compared to 2011, and another 6 points in 2013.

Companies should be defensive in this stage, now defending their lead instead of their first mover advantage. Defending a leading position requires growing the core business. Indeed, most inverter suppliers including Schneider Electric are continuously offering new products to complete their line of offers. Not listening to the market and becoming complacent is the biggest threat in a mature industry; especially in the solar industry with its continuous policy and regulation changes.

Based on the characteristics of the Consolidation Curve, which stage do you think the solar industry is in?
