1. Material Grade

Solar panels are primarily made from silicon, which comes in various grades. The most common types are monocrystalline, polycrystalline, and thin-film. Monocrystalline panels are known for their high efficiency and longevity, making them ideal for limited space. Polycrystalline panels are generally less expensive but offer slightly lower efficiency. Thin-film panels are lightweight and flexible, suitable for specific applications but typically less efficient.

Importance: Selecting the right material impacts energy conversion rates, installation options, and long-term performance, directly influencing project costs and ROI.

2. Tolerance

Tolerance refers to the permissible deviation from the rated output power of a solar panel. It is expressed as a percentage and indicates how much the actual output may vary from the stated capacity. A typical tolerance range is ±3% to ±5%.

Importance: A lower tolerance percentage means higher reliability and predictability in energy production, critical for project budgeting and energy planning.

3. Temperature Coefficient

This specification indicates how much a solar panel’s efficiency decreases with rising temperatures, usually expressed in percentage per degree Celsius. For example, a temperature coefficient of -0.4%/°C means that for every degree above 25°C, the panel’s output drops by 0.4%.

Importance: Understanding this property helps buyers anticipate performance in different climates, essential for regions with high ambient temperatures.

4. Degradation Rate

The degradation rate measures how much a solar panel’s efficiency declines over time, typically expressed as a percentage per year. A good quality panel may have a degradation rate of around 0.5% to 1% per year.

Importance: A lower degradation rate ensures better long-term performance and return on investment, making this a key consideration for buyers focused on durability.

5. Power Output Rating

This rating indicates the maximum power a solar panel can produce under standard test conditions (STC). The power output is measured in watts (W) and is crucial for system design and energy forecasting.

Importance: Knowing the power output allows buyers to calculate how many panels are needed to meet energy requirements, influencing system size and cost.

Common Trade Terminology in Solar Procurement

Familiarity with industry jargon is essential for effective communication and negotiation in the solar market. Here are some common terms that B2B buyers should know:

An OEM produces components or products that are used in another company’s end product. In the solar industry, this often refers to manufacturers that produce solar panels for other brands.

Importance: Understanding OEM relationships can help buyers evaluate product quality and brand reliability.

2. MOQ (Minimum Order Quantity)

MOQ is the smallest number of units a supplier is willing to sell. This term is crucial for buyers to know when negotiating with manufacturers, as it can affect overall project costs.

Importance: Buyers must align their purchasing plans with suppliers’ MOQs to avoid excess inventory and optimize cash flow.

3. RFQ (Request for Quotation)

An RFQ is a document that a buyer sends to suppliers to request pricing and availability for specific products. This process is essential for comparing offers and making informed purchasing decisions.

Importance: Crafting a clear RFQ helps ensure that suppliers provide accurate quotes, reducing the risk of misunderstandings.

4. Incoterms (International Commercial Terms)

These are predefined commercial terms published by the International Chamber of Commerce (ICC) that clarify the responsibilities of buyers and sellers in international transactions. Common terms include FOB (Free on Board) and CIF (Cost, Insurance, and Freight).

Importance: Understanding Incoterms helps buyers anticipate shipping costs, delivery responsibilities, and risks associated with international procurement.

5. Watt-Peak (Wp)

Watt-peak is a measure of the maximum output of a solar panel under standard test conditions. It is a critical specification for understanding the efficiency of solar panels.

Importance: Knowing the watt-peak rating helps buyers compare different panels and assess their potential energy production.
