Selecting the right solar transformer is crucial for the success of any photovoltaic project. Several factors should be considered:
1. Voltage Level: Ensure the transformer supports proper step-up from inverter output (0.4kV / 0.69kV) to grid voltage (10kV–35kV).
2. Transformer Type:
- Oil Immersed Transformer – best for utility-scale solar farms
- Dry Type Transformer – suitable for indoor or rooftop systems
- Pad Mounted Transformer – widely used in North America
3. Capacity Range: Typically from 1MVA to 20MVA depending on project size
4. Environmental Conditions: Outdoor solar farms require robust and durable transformer designs
Working with a reliable solar transformer manufacturer ensures customized solutions and long-term project stability.
