Second-quarter earnings for solar companies kick off next week, and Goldman said two stocks in particular should be on investors' radar: Enphase Energy and SolarEdge .
The firm said in a recent note to clients that both companies have the potential to beat quarterly estimates, while also raising guidance.
Analysts led by Brian Lee said both companies, which make inverters for solar systems, are benefitting from strong demand in Europe, as well as demand for their energy storage products.
Goldman has a $244 12-month target on the stock, which is 11% above where the stock closed on Thursday.
On the other hand, Goldman is cautious on the panel suppliers, rating First Solar , JinkoSolar and Maxeon Solar as sells.
