The function of voltage regulator in solar biomass hybrid power plant

 

What is a Solar Biomass Hybrid Power Plant?

The combination of two or more power production cycles to generate more electricity than a single power generation system while minimising the disadvantages of single power cycles is called a hybrid power plant. One of the more popular hybrid power generation systems available in the market is the solar-biomass power generation system.

What is a voltage regulator?

The power generated from solar panels is stored in solar batteries. A solar voltage regulator ensures that these solar batteries do not overcharge and thus controls and modulates the voltage from the solar panels to the solar batteries and connected electronics.

Types of voltage regulators

There are essentially two types of voltage regulators — Pulse Width Modulation (PWM) and Maximum Power Point Tracking (MPPT)

PWM regulators act as a link or switch between the solar panels and solar batteries and employ a transistor rather than a relay to open the array. They also single-handedly adjust the width and speed of the pulses transmitted to the battery. They are less expensive and commonly used in small solar panel installations.

MPPT voltage regulators allow the array voltage to differ from the battery voltage, making it simple to determine the point at which the solar array provides the most electricity. However, heat dissipation is an issue with larger solar panels.

Since MPPT controllers are primarily step-down converters, the array voltage must always be greater than the battery voltage. The primary function of MPPT solar regulators is to prevent the solar power system from losing power generated by solar panels while simultaneously obtaining the maximum power from the solar array. MPPT controllers are more expensive than PWM controllers, but they are also more efficient in terms of system losses.

Why is a voltage regulator needed?

According to the intensity and the position of the sunlight, the voltage received from the solar panels differs and is inconsistent. If unregulated, this voltage may end up causing unnecessary heating of the solar battery while charging. Thus, to regulate the voltage, a voltage regulator is necessary between the solar panel output and the battery input.

The solar panel’s voltage regulator operates as a blocking diode when the battery voltage exceeds the solar array voltage. It guarantees that the voltage from the solar panel never exceeds the safe charging voltage of the battery. A voltage regulator is generally not required if the solar panel output is 2 watts or less for every 50 battery amp hours.

Conclusion

Solar voltage regulators are critical components of off-grid solar power plants. Without them, batteries will be unable to keep up with the solar array’s current variations. Furthermore, when choosing a solar voltage regulator for your solar power plant, it is important to ensure compatibility between the regulator and the voltage of your solar power system so that the former can withstand the maximum output current of your solar panel or array.

What Type of Approval is Required to Set up a Solar Power Plant in India?

 

India is a country blessed with enormous amounts of sunlight throughout the year. The increasing innovation in the solar industry and the hazardous effect of fossil fuels for power generation are encouraging more people to go solar. However, people need to follow certain rules laid out by the government to install a solar power plant.

You can choose either a rooftop solar power plant or a ground-mounted solar plant to generate sustainable electricity. Both these systems have different approval and permit requirements. Moreover, people need to deal with government agencies who guide them throughout the installation process.

Here are the major approvals and permits people need to install solar power plants. Approvals for Rooftop Solar Power Plants

The permits needed for installing rooftop solar plants vary with state laws, the capacity of the solar plant, and the building sector, such as industrial, commercial, or domestic. However, in most Indian states, people need peppermint in two folds. These include the following:

• Submitting the application form to DISCOM along with the application fee.
• After reviewing the application, the authorities decided to give approval for the applied capacity of the solar plant.
• In the next step, the rooftop owner registers for installing solar power plants with the required documents and makes the payment of registration charges. Here people also need to apply for the net metering facility for their solar plant.
• Following this, the customer signs the connection agreement with DISCOM for the initiation of the installation process.
• Once the installation of the solar plant completes, DISCOM officials evaluate the standard compliance and sanction the project.

Approvals for Ground-Mounted Solar Plant

The permission procedure for ground-mounted solar projects also depends on the state in which it is installed, similar to the solar power plants on rooftops. In addition, people need the following permissions for the ground-mounted solar power plants as a form of standard registration procedures:

• After the feasibility analysis of the site from the local substation to ensure the ability of the grid to handle the power level of the solar power plant, people need to get a permission letter for power evacuation from the DISCOM.
• Requirement of a land conversion certificate when using agricultural land. This certificate is necessary to prove that the land will no longer be used for agricultural purposes.
• License for contract work issued by the labour department.
• Approval for sewage treatment facilities.
• Permit of the environment clearance by the pollution control board.
• Fire department’s certificate of fire safety.
• Clearance permit from the forest department.
• Chief Electrical Inspector’s approval for project commissioning.
• MNRE approval for the solar power project’s tax exemptions.

Conclusion

SWRE is a leading solar EPC solution provider, which has succeeded in setting up large solar power plants throughout the globe. The company initially started as a combined effort of Shapoorji Mistry Sr. and Mehervan Daruvala. By 1920, Wilson Electric Works managed the electrical contracts at Shapoorji Pallonji Construction. Later in 1971 Wilson Electric Works got investments from Sterlings (Shapoorji Pallonji Group) and took up large projects in the Middle East, the Asian subcontinent, and several other countries.

Looking at the rising demand for solar energy, SWRE started its operations in this industry in 2017 and became the leading service provider at the global level. Through the years it has bagged multiple awards with the latest recognition from RenewX as Leading EPC in 2022.

Explain the Challenges Faced by Developers of a Solar Power Plant

 

The abundant availability of solar energy provides great opportunities for the growth of the solar power industry. Moreover, solar technology can use solar energy for multiple purposes, such as generating electricity, heating water, providing a comfortable interior environment, etc. However, the most attractive feature offered by solar power is that it is completely sustainable and leaves zero carbon footprint.

Despite the benefits of solar power systems, industries face multiple problems producing and setting up solar panels. The most common challenges are discussed in this blog.

Solar Radiation Intensity

One of the greatest barriers to the widespread use of solar electricity is the intensity of the sun’s radiation. The intensity keeps changing according to the geographical location of a place. The poles receive the least amount of solar radiation each year, while the equator receives the most. Climates that are dry receive more solar radiation than those that are cloudy. Moreover, the amount of usable solar energy that is incident at any given area depends greatly on its latitude and climate.

Solar Panel Efficiency

Solar panels use photovoltaic effects to convert sunlight into usable electricity. However, the panels are able to convert only 17% to 19% of the captured light into electricity. This means nearly 80% of the solar energy gets wasted during the process. Therefore, industries need to develop solar panels that offer high efficiency so that more units of power can be generated from every single panel in the solar system.

Reliability

Another significant issue faced by solar panel manufacturers is the reliability of solar electricity. A solar panel can produce electricity merely for a maximum of 12 hours daily. Moreover, it reaches its maximum output briefly around noon when the sun’s rays are highly intense.

To solve this issue, solar manufacturers provide trackers to rotate the solar panels in the direction of the sun. However, this system also depends on the intensity of sunlight, which is maximum during noon. Another way to get access to solar power when the sun is not out is storage batteries, which charge during the day to provide an uninterrupted power supply at night.

Requirement of Land

Although solar panels can be installed on rooftops to meet domestic power requirements, large-scale solar power production requires a vast land area free from shading. This brings challenges for small countries with limited open areas or large countries with open areas reserved for farming or agriculture. However, to solve this problem, manufacturers have developed solar panels that can be installed on water bodies.

Environmental Concerns

Although solar power generation creates zero pollution, the manufacturing process of solar panels and storage batteries leads to environmental degradation. Nitrogen trifluoride, a common byproduct of solar cells, is more dangerous than carbon dioxide. However, manufacturers all around the world are labouring hard to develop more environmentally friendly ways to develop solar panels.

Conclusion

Similar to any industry, solar also faces multiple challenges. However, leading manufacturers like Sterling and Wilson Renewable Energy are taking steady steps to tackle all the problems relating to solar power generation to restore the disturbed atmospheric balance.
