A photovoltaic (PV) system can change hands multiple times throughout its 20+ year lifespan. In each transaction, the buyer and seller often have very different perspectives on the value of the project or portfolio. The seller will aim for the highest possible price, while the buyer will try to negotiate the lowest. Ideally, the final sale price will fall somewhere in between the two parties' initial expectations. However, the real challenge comes when it's time to evaluate the technical aspects of the system—this is where the actual value is determined.
This article serves as a guide for buyers looking to influence the price based on a thorough technical risk assessment of the PV system. By understanding potential risks and inefficiencies, buyers can make more informed offers that reflect the true condition and performance of the asset.
Sellers typically issue a Request for Proposal (RFP) to attract qualified buyers interested in purchasing a single installation or a portfolio of projects. The RFP usually contains high-level information about the assets, and interested parties are then narrowed down to a shortlist. This shortlist is given access to more detailed technical data, along with limited time to review, ask questions, and submit their final offer.
It’s important for buyers to request specific documents to fully understand the system’s condition. These include:
1. **Engineered Drawings (Electrical/Mechanical/Civil)**
2. **Solar Yield Models (PVSyst Reports)**
3. **Equipment Datasheets**
4. **Interconnection Approvals**
5. **Construction Permit Approvals**
6. **Commissioning Reports**
7. **Maintenance Logs**
8. **Historical Energy Data**
The due diligence process is time-sensitive and requires a team of experts, including electrical engineers, civil engineers, construction managers, O&M technicians, asset managers, and performance analysts. Many buyers choose to hire an independent engineering firm to conduct this evaluation, especially when dealing with complex, multi-disciplinary systems.
An independent engineer (IE) should structure their work in stages, allowing the buyer to stop the process if high-risk issues are identified early on. A typical technical due diligence process might look like this:
- Review of equipment, permits, and interconnection approvals
- Engineering design and yield assessment
- Commissioning and maintenance log analysis
- Historical energy production review
- On-site physical inspection
During each phase, the IE can identify critical risks that may affect the system’s performance, reliability, or compliance. Common high-risk observations include:
- Equipment from manufacturers no longer in business
- Missing or incomplete permits and approvals
- Non-compliant interconnection methods
- Design flaws leading to higher costs
- Unrealistic solar yield projections
- Lack of proper commissioning or maintenance records
- System underperformance or accelerated degradation
- Physical damage or environmental impacts
The IE’s report provides an unbiased assessment of the risks involved. It’s crucial for the buyer to clearly communicate their risk tolerance so the report can be tailored accordingly. Each deficiency should be rated for risk and accompanied by estimated remediation costs. This allows the buyer to negotiate effectively and justify their offer based on real-world data.
By leveraging a comprehensive technical evaluation, buyers can make smarter decisions, avoid costly surprises, and ultimately secure a fair and accurate price for the PV system.
Round hole perforated metal is a type of metal Perforated Sheet or Perforated Mesh that has been processed to have circular openings or holes cut into it, typically with a diameter ranging from very small fractions of an inch to several inches. This material is used in various applications due to its unique properties:
Applications:
1. Aesthetic Purposes: Decorative applications where the perforations can be used for creating patterns or designs.
2. Lightweight Construction: Due to its open structure, it is used in lightweight construction and fabrication where weight reduction is important without compromising structural integrity.
3. Acoustic Control: Used in architectural settings to control sound absorption or reflection.
4. Ventilation: In HVAC systems, round perforated metal is used for creating efficient airflow patterns.
5. Security Grilles: For security purposes in windows, doors, or other areas requiring protection against intrusion.
6. Industrial Use: In machinery parts, filters, and screens where specific air or liquid flow rates are required.
Properties:
- Material: Round hole perforated metal can be made from a variety of materials including stainless steel, aluminum, carbon steel, and brass, depending on the application requirements.
- Hole Size: The size of the holes can vary widely, from tiny holes for fine filtration to larger ones for ventilation or aesthetic purposes.
- Pattern: The spacing between the holes (pattern) can also vary, affecting the overall openness of the sheet and its performance in different applications.
- Thickness: The thickness of the sheet determines its strength and weight, influencing its suitability for different uses.
Manufacturing Process:
The process of creating round hole perforated metal involves using specialized machinery that uses a die or punch to cut precise circular openings in a flat metal sheet. The sheet is usually first slit into strips before the perforation process begins, ensuring uniformity and precision in the final product.
Customization:
Perforated metal sheets can often be customized in terms of hole size, pattern, material, and thickness to meet specific project requirements. This makes them highly versatile across many industries.
