This was a fairly unexpected announcement from Tesla on Friday, although we did have prior warning. BIPV has always presented a challenge of matching the efficiencies and costs of regular PV modules. BIPV will never be able to compete fully on these grounds with modules but they certainly do have a market. The aesthetics of solar tiles have always been a little underwhelming but these new Tesla PV tiles certainly look the part. What I really want to know now is some data on outputs and efficiencies. More information required Mr Musk!
