Overview: Solar Power in the United Kingdom

Solar power represented only a very small part of electricity production in the United Kingdom (U.K.) until the 2010s when it increased greatly. The sudden and rapid increase of solar power can be attributed to the fact that most of the new installations in that decade were subsidized with a feed-in tariff (FIT), as well as the fact that the cost of photovoltaic panels was — and has been — rapidly falling.

As of 2019, the installed capacity in the U.K. has been over 13 GW. With the 72 MW (DC), Shotwick Solar Farm is the largest solar project in the U.K., but its peak generation was only less than 10 GW. Since panels have a capacity factor of around 10% in the U.K. climate, the average annual generation is roughly the installed capacity multiplied by 1000 hours, being slightly under 13 TWh in 2018 which is somewhat under 4% of the U.K. electricity consumption.

Wholesale Disconnects for Solar Systems

Essentially, safety disconnects allow users to rapidly shut down the system in case of an emergency. For this reason, disconnect switches are required to comply with electrical codes and pass inspection. 

A solar PV system usually has two safety disconnects. The first is the PV disconnect (or array DC disconnect). This kind of disconnect allows the DC current between the modules (source) to be interrupted before reaching the inverter. 

The second disconnect is the AC disconnect. The AC disconnect is used to separate the inverter from the electrical grid. In a solar system, the AC disconnect is typically mounted to the wall between the inverter and utility meter. This kind of disconnect may be a breaker on a service panel, or it may be a standalone switch. Additionally, it is sized based on the output current of the inverter. 

How to Size an AC or DC Disconnect?

Generally speaking, sizing refers to equipment, components, and connectivity (wiring) throughout a solar system as it relates to NEC requirements. The following terms are used to determine component output: 

  • Voltage
  • Circuit load
  • Amps or breaker size
  • Wiring or cables
  • Sizing and Protection of the AC Disconnect

NEC 690.10 stipulates that the circuit conductors between the inverter output and the building or structure disconnecting means shall be sized based on the output rating of the inverter. These conductors shall be protected from overcurrents in accordance with Article 240. The overcurrent protection shall be located at the output of the inverter. 

Important Features to Look For in Disconnect in Bulk?

Disconnects are incredibly useful for solar systems, and so, it is important to get the best possible disconnect for your own solar system. The following are the core features to look for in a disconnect: 

  • Offers bi-directional functionality, which breaks the arc regardless of normal or a reverse current flow
  • Includes all required components to meet NEC 690 requirements, including jumpers and labels
  • Guards against accidental contact with live parts with clear polycarbonate dead fronts
  • Available with modifications that allow customization to meet any application need
  • Sizing of Module Interconnection Conductors and DC Overcurrent Protection

According to NEC 690.80, where a single overcurrent device is used to protect a set of two or more parallel-connected module circuits, the ampacity of each of the module interconnection conductors shall not be less than the sum of the rating of the single fuse plus 125% of the short-circuit current from the other parallel-connected modules.
