Solar Market Outlook in Croatia

Croatia holds immense potential when it comes to its renewable energy generation and reliance. This has prompted the government to set an ambitious target of 30% renewable energy consumption by 2030. 

In 2008, the renewable energy capacity in Croatia was only at 1%. By 2018, it was at 17%, which signals a 15% yearly growth rate for the country’s solar and renewable energy capacity. This projection was detailed in the government’s program to boost solar capacity – the National Renewable Energy Action Plan.  To boost this growth potential, the Croatian government has looked at improving feed-in-tariffs and premium tariff support schemes.

As of 2021, the projected solar energy capacity in Croatia is at 6.8 GW. Of this capacity, 5.3 GW is attributed to utility-scale PV plants and the rest (1.5 GW) is attributed to rooftop solar systems.

The government is serious about its renewable energy efforts such that they are drafting a law to identify potential obstacles to its renewable energy campaign, as well as ideas on how to remove those obstacles.

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.
