When the markets get dicey, along with high-profile momentum stocks, one of the first groups to get hit hard are the clean technology and solar stocks. The recent wild swings caused by end of the quarter window dressing and the ongoing Greek potential default may be giving investors an incredible opportunity to buy top solar and renewable energy stocks.

A new report from Deutsche Bank says that the current weakness is providing an attractive entry point for long-term investors. The analysts continue to view yieldcos as a significant growth catalyst for the solar and broader renewables sector, and expect yieldcos to not only increase the availability of capital, but also provide significantly lower cost of capital to the renewables sector.

We ran a screen and searched for the top yieldcos to buy now. All have been hit hard.

TerraForm Power

This stock has held up much better, down less than 5% since early June, and may be just the right stock for investors that like the sector, but want a more conservative route. TerraForm Power Inc. (NASDAQ: TERP) owns and operates solar and wind generation assets serving utility, commercial and residential customers. Its portfolio consists of solar projects located in the United States, Canada, the United Kingdom and Chile with total nameplate capacity of 887.1 megawatts. The company was formerly known as SunEdison Yieldco and changed its name last year, and it is perhaps one of the highest profile companies operating as a yieldco. Some Wall Street analysts see distributions rising to 5.65% by 2017.

Many Analysts feel that the combination of dividends and a growth-oriented company in the renewable energy field makes good sense. The also note that the company’s relationship with the sponsor SunEdison is a positive because of its large development pipeline and incentive to grow TerraForm’s portfolio, which is composed of projects with long-term contracts in place, solid counterparties with high investment grade credit ratings, very diversified assets (including solar and wind projects) and low asset ages.

TerraForm investors are paid a 3.41% distribution. The consensus price target is posted at $44.10. The shares closed Wednesday at $37.90.
