For those who shy away from investing in a solar system, the company Enpal has developed an alternative. Customers have the option of renting a photovoltaic system as part of an all-round carefree package with a term of 20 years. The online solar provider promises to take care of installation, maintenance and operation completely. There should be no major acquisition costs or complicated bureaucracy for the customer. After 20 years the costs for the solar plant are paid off and the customer can take over the plant for free and use the solar electricity free of charge.
