Latest Case Study

Pangbourne, Berkshire - 9.135 kWp (Dec '23)

In December of last year Spirit installed a 9.135 kWp system for Mr S of Pangbourne. A large south facing roof allowed for an impressive array of 21 Black Jinko panels.

With the help of a Tesla Powerwall 2 and gateway, Mr S. is expected to use 57% of the energy he generates on site, exporting the rest back to the grid - all while achieving 97% grid independence over a year and 100% in the summer months.
