Liechtenstein

Solar Market Outlook in Liechtenstein

Liechtenstein is one of those countries in Europe that relies heavily on renewable sources for its total energy production. Therefore, it comes as no surprise that it has a solar energy plan in place to generate electricity for its residents and businesses. 

However, the total amount of production of solar power in Liechtenstein is still limited given its limited space and infrastructure. This is also what limits the country from being able to completely rely on renewables to cover its domestic energy needs and supply. 

It wasn’t until recently when the Liechtenstein government has ventured into solar energy production. It uses photovoltaic panels that are mounted on buildings in order to generate solar energy. Therefore, there are no solar power plants yet in Liechtenstein. The biggest solar PV installation in the country is currently able to generate 112 KWp. 

Solar Energy Equipment Supply Capacity in Liechtenstein

Not only does Liechtenstein have limited access to solar infrastructure, there is also no domestic supplier or manufacturer of solar equipment. As of now, it depends on importation of solar power equipment to install solar PVs in residential and commercial buildings in order to generate solar energy. There are also many online suppliers that provide a wide range of options when it comes to solar power components and accessories for small or large scale installations. 

Top Major Seaports & Logistics in Liechtenstein

Liechtenstein is a landlocked country and is very small. Therefore, it’s only seaport is in Schaan and this is where commercial and trade activity takes place.

Electrical Disconnect

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.
