UK Solar Capacity Grew 1100% in 2011

According to the weekly solar pv installation and capacity statistics released by the Department of Energy and Climate Change (DECC) this week, the UK capacity of solar pv rose by a massive 697.1MW in 2011 to a total of 761.9MW. This works out as an increase of over 1100% in just one year!

Of this, a substantial 125.9MW was installed in the week leading up to the 11th December, the day before the proposed Feed-in-Tariff (FiT) change. Thats nearly a fifth of the installed capacity for the whole year.

Using the figures, we’ve calculated that if the weekly installed capacity had remained at the same level as the week before the plans were announced, then installed capacity this year would have been 454.7MW, still a good effort but a gigantic 242.4MW less than the actual amount installed. This shows the sheer magnitude of the bubble caused by the proposed cuts.

These statistics are compiled from the MCS registration database and so includes all installs that have been registered with MCS, whether or not they have since been approved for the FiT. It therefore doesn’t include installs that haven’t been registered with the MCS.
