Tesla is entering the solar business at a risky time

Solar has generally been a difficult business, and that isn't looking to change under President-elect Donald Trump.

Tesla officially acquired SolarCity in a deal worth roughly $2 billion on Monday. Prior to the shareholder vote, Musk unveiled several solar products that will become the focus of Tesla's energy line. They include roof shingles that look like a normal roof, but are embedded with solar cells to generate energy, as well as an at-home battery, Powerwall 2.

Tesla will also continue to install larger solar array projects using its commercial battery, Powerpack 2, as was the case with the island of Ta'u that is now running almost entirely on solar power.

As is always the case with Tesla CEO Elon Musk, he did not enter the solar business half-hearted.

He has an entirely new product, the solar roof, to make converting over to solar energy more aesthetically pleasing, and therefore more alluring, transition than traditional, clunky solar panel installation.

He's also generating excitement for solar power through projects like the Ta'u solar project, similarly to what he did for electric cars. As Business Insider's Matt DeBord has written, Musk is a master marketer, and it could pay off for solar the same way it did for EVs at a time of general unpopularity.

But the solar industry, in general, has been fledgling — and it doesn't look like a Trump presidency will make things any easier.

SolarCity's cash problem

Tesla acquired SolarCity's roughly $3 billion in debt as part of the merger. According to Bloomberg, debt is endemic among the solar industry — the industry has borrowed $200 billion since 2010. Industry-wide cash flow also declined massively in that period by $3 billion.

As for SolarCity itself, the company posted losses in all but three quarters since its IPO in 2012, and its shares have declined by over 50% this year.

Now, debt is fairly common among project power developers. Tesla commented on SolarCity's debt in a Nov. 1 blog post, stating that SolarCity's assets significantly exceed its recourse and non-recourse debt. Musk has also said he would personally pay off SolarCity's debt if need-be in a Nov. 4 tweet.

Still, debt issues aside, whether SolarCity can generate the cash flow it needs has yet to be seen.

SolarCity did change its strategy in 2016 to become more cash positive. The company has conventionally leased panels, but is now selling more panels to increase cash flow. SolarCity introduced a loan program in June to incentivize purchasing as part of that change in strategy.
