The company plans to use the capital to install more than 13,000 new renewable energy solutions. Enpal finances the investments with the help of major banks, and the difference between rent and interest costs remains with the company as profit.

Most recently, there had been criticism of Enpal's rental model from consumer advocates and competitors. The comparison portal Verivox came to the conclusion that a purchase is always cheaper than renting – provided that customers do not have to take out a loan. In the meantime, Enpal also offers solar systems for sale.
