What is BoM in solar?

The ‘bill of materials’ (BoM) of a PV module include the encapsulants, front surface, back sheet (for mono-facial) and cell interconnections. An encapsulant is important for solar cell adhesion to the front and rear surfaces of the module.

What is horizontal global irradiation?

Definition: Amount of solar energy (integrated over a time) attenuated by all constituents of the atmosphere and falling on a horizontal surface on the Earth. Global horizontal irradiation integrates direct, diffuse and reflected components of solar energy [Wh. m-2].

What is kWh kWp?

Specific yield (kWh/kWp) is one of the most commonly used performance metrics for solar systems of all sizes. It’s used to compare different locations, to analyze different designs or to assess the health of an array.

What is the unit of solar irradiance?

watts per square metre
Units. The SI unit of irradiance is watts per square metre (W/m2 = Wm−2). The unit of insolation often used in the solar power industry is kilowatt hours per square metre (kWh/m2).

What is DNI and GHI in solar?

Global Horizontal Irradiance (GHI) is the total amount of shortwave radiation received from above by a surface horizontal to the ground. This value is of particular interest to photovoltaic installations and includes both Direct Normal Irradiance (DNI) and Diffuse Horizontal Irradiance (DIF).

How do you convert kW to kWp?

A kilowatt equals 1,000-watts, so if you use a 1,000-watt appliance for one hour, you’ll be consuming 1 kWh of energy. If your solar system has a kWp of 1,000-watts, for example, your kWh to kWp ratio is 1:1. Of course, this is at peak performance, so the ratio is, in reality, a fair bit lower.

Is kWp the same as kW?

KWp is the nameplate rating of Solar PV modules and kW is the actual power delivered to the load. For instance, a 0.3kWp (300Wp nameplate) module under ideal conditions (25 degrees C and 1000 watts per sq. metre radiation, etc.) will give an output of 0.3kW.

What is irradiance 1000w m2?

Above the earth’s atmosphere, solar radiation has an intensity of approximately 1380 watts per square meter (W/m2). This value is known as the Solar Constant. At our latitude, the value at the surface is approximately 1000 W/m2 on a clear day at solar noon in the summer months.

How does BOM work?

A bill of materials (BOM) is a centralized source of information containing a list of items used to manufacture a product and the instructions on how to do so. Often shown in a hierarchical way, a bill of materials (BOM) lists the finished product at the top, down to individual components and materials.
