Design And Analysis Of Solar Panel Supporting Structure In Wind Effect Shape

The utilization of renewable energy resources is increasing rapidly over the globe. Following this trend, the implementation of large-area solar arrays is an essential part. Many design approaches to the supporting structures have been presented in order to attain the target of maximum efficiency.

Renewable energy resources are loaded mainly with aerodynamic pressures. International governance and the competition between industries define that they must withstand the enormous loads that result from large air acceleration. They must have a life assurance of more than 20 yrs.

Optimization plays a vital role in product design and prevents unnecessary inventory from satisfying functional needs. But optimization with apt design helps to build efficient products in the everyday competing market. Stress analysis also plays a vital role in optimizing the designs.

Due to the advancement in computer-based finite element software’s design process is made simple by easier simulation methods fast replacing prototype built up and testing. In the current scenario, a solar panel aiding structure is crafted to take rotational loads for safe operation. So the designs should consider the loads coming on the structure for rotation along with the inertia effect of the rotating members. The mechanism should withstand the aerodynamic loads, inertia loads and rotation loads along with frictional loads. The model should look at aerodynamic circumstances for loading calculations, and the design should satisfy all the functional requirements.

Various Solar Cell Design Principles to look out for

The Solar Cell design is a key process for producing highly efficient solar cells with high quality and low cost effects. Within a certain set of limitations, the solar cell design process includes the specification of the parameters of solar cell structure for the purpose of maximizing efficiency. These limitations will be determined by the conditions and working environment in which the solar cells are produced. For instance, the solar cells produced in a commercial environment are much more cost-effective, and the cost of fabricating a specific solar cell structure is one of the main considerations to be taken care of. The solar cells produced have the motive to make the production of the highest possible efficiency for a laboratory-type cell.

Evolution Of Silicon Solar Cell Efficiency

Solar cells that are made up of silicone are more used to be accurate under the conditions of one sun operation at around 29%. The current maximum measured efficiency for a silicon solar cell is 24.7% under normal conditions. The gap between the higher theoretical efficiencies and the actual efficiencies measured from terrestrial solar cells is based on two basic elements. The first one is that the theoretical efficiency calculations assume that energy from every photon is used optimally, that no photons are unabsorbed and that every photon is absorbed in a material with a band gap equal to the energy of the photon. Theoretically, this can be achieved by modeling an infinite stack of solar cells of variable band gap materials, each one only absorbing the photons exactly corresponding to its band gap. The second one is that higher theoretical efficiency assumes a high concentration ratio. With the assumption that the temperature and the resistive effects do not govern in the concentrator solar cell, the increase in the light intensity leads to an increase in the short circuit current. Since the VOC  (open circuit voltage) also relies on the short circuit current, VOC increases as well with light level. In addition, because the maximum fill factor increases with VOC, the possible maximum ff increases as well with concentration. The additional VOC and ff increase with concentration which allows for higher efficiencies in concentrators.

Solar Cell design Principles

In the design process of single junction solar cells, the principles for having maximum cell efficiency are:

  • Increasing the quantity of light collected by cells is converted into carriers
  • Increasing the collection rate of light-generated carriers by the p-n junction
  • Minimizing the forward bias dark current
  • Extracting the cell current with no resistive losses.
  • What factors determine the size of the right solar system?

There are five key factors that are used to calculate solar system size:

  • Usage
  • Solar insolation and weather
  • Roof characteristics
  • System losses
  • Battery storage

The amount of energy you utilize is the most important factor that determines the size of the solar system. The size of the panel results in increased savings.

Solar Cell design Principles

Solar insolation and weather

This factor is extremely locational dependent if we compare peak sunlight hours (PSH) - a measurement of the average amount of sunlight which is received by the place.

Roof characteristics

The orientation and pitch of your roof will determine the orientation and angle of your solar panels. Both factors are going to impact the production of solar energy.

System losses

Because of the factor that all of the solar panels are experiencing system loss, you will not have access to the full DC output of your solar panels.

Battery storage

The shortage of battery power for a solar power system can also impact the size of the solar system.
