Protecting Investment, Ensuring Quality
In solar power plant projects, panels are not only the heart of energy production but also represent a significant portion of the financial investment. Estimates show that about 35% of the total value of a solar plant is related to its panels. Therefore, drafting purchase contracts with strong technical precision and appropriate conditions is vital for project success, reducing operational risks, and accelerating return on investment.
Aseman-Rasad Hadi, with years of experience in testing, inspection, and quality monitoring of solar panels, provides specialized consulting services for panel purchase contracts to employers, investors, and EPC contractors. These consultations are based on real data, field experience, and a deep understanding of the technical and legal requirements of the solar panel market.
Why Do Panel Purchase Contracts Require Technical Consulting?
In many projects, panel purchase contracts are drafted solely based on price or brand, without considering technical details, testing conditions, warranty requirements, or delivery procedures. This oversight can lead to serious future problems, such as:
- Delivery of defective or low-quality panels
- Inability to pursue warranty claims due to lack of test documentation
- Disputes with sellers or manufacturers in case of power degradation
- Increased maintenance costs and reduced actual plant output
Technical consulting during contract drafting prevents these issues and ensures a safe and transparent project path from the start.
Our Consulting Services in Panel Purchase Contracts
Aseman-Rasad Hadi provides specialized consulting in the following areas:
- Review of Panel Technical Specifications
We evaluate proposed panels in terms of nominal power, efficiency, cell type, thermal tolerance, open-circuit voltage, short-circuit current, and compliance with international standards. This helps clients make informed choices tailored to project conditions.
- Defining Testing and Inspection Criteria
Based on extensive field testing experience, we define testing and inspection criteria in contracts. These include test types, execution conditions, sample sizes, acceptance/rejection thresholds, and documentation methods.
- Designing Sampling and Random Testing Processes
We design sampling procedures according to ISO 2859 standards, including sample size selection, random sampling methods, portable EL testing at customs or site, and classification of results into Healthy, Minor, Major, and Critical defects.
- Drafting Technical and Legal Clauses in Contracts
We assist clients in including technical clauses related to quality, testing, warranty, delivery conditions, and seller responsibilities. These clauses provide strong legal backing for claims and compensation in case of disputes.
