In Spain, electrical energy produced form PV panels in installations of less than 100 kWp and sold to the electricity company via the grid must be legally bought at 5.5 times the standard energy price per kWh. This enables amortisation of a medium scale PV installation in a period of approximately 10 years, while the useful life of the installation is between 25 and 30 years. Given that this multiple is guaranteed for the 25 year life of the installation, this is a significant investment opportunity and especially if the customer is in possession of a suitable site for the installation.

expert solar systems will take on the entire project, from the negotiation of government grants to the homologation of the system by the electrical company as well as the design, installation and maintenance of the installation.
