A solar power plant is sometimes referred to as a solar energy system, solar system, solar power system and solar plant. The efficacy of solar power can be estimated by the fact that by harnessing just one and a half hour’s sunlight, the entire world can satisfy its energy needs for a year. To collect maximum sunlight for converting it to electricity, solar photovoltaic technology is the best alternative.

In other words you can say solar power system is based on the conversion of sunlight into electricity, either directly by using photo-voltaic (PV) panel or indirectly by using concentrated solar power (CSP).

There are three types of power systems available in various power ratings, so it’s worth spending 10 minutes reading this information and selecting the best that meets all your requirements.

Types of Solar Power Plant

Everyone these days is well aware of the advantages of going solar. Being attracted by the significance of the most abundant energy source, many people are switching towards making solar energy their main source of energy. But before doing that, one should always be careful while selecting the type of solar power plant. Since it is the major thing that decides whether the power plant will prove to be beneficial for you or not. 

If you are ready to switch to a solar power plant but you are concerned about which type is best for you, we are here to provide you with complete details about all the types of solar power plant.

Three Types of Solar Power Plant

Basically, solar power plants are mainly available in three different types. The first one is the on grid solar power plant, second is off grid solar power plant and the third is hybrid solar power plant. 

On-Grid Solar System – Saving + Grid Export

Off-Grid Solar System – Saving + Backup

Hybrid Solar System – On-grid + Off-grid

Difference between on-grid, off-grid and hybrid solar power plant

Starting with the basics, the main point of difference between on-grid, off-grid and hybrid solar power plant lies in their relationship with the utility grid. An on-grid solar system works with the utility grid while off-grid does not bother about the same. Moreover, a hybrid system depends partly on it. All type of solar power system is different from each other on the basis of their specifications and features while all solar power system works on same principle. Also, some of the components are different in each type of solar power system.

Other Types of Solar Power Plant 

All of the above-mentioned types of solar power plants can further be divided into two sub-categories. These two categories are:

Read further to know more about these types of solar power plants and make your choice more precise. Mentioned below is the complete set of details like their area requirement, working, technical specification, govt. subsidy on solar, net-metering system.

Off-Grid Solar Power System

In India, there are still several remote areas where there is no electricity at all. Plenty of homes are still living with the crisis of power outages. Besides, there are areas where the electricity supply is not consistent or sufficient. For people residing in such areas, an off grid solar power system is a boon as this system requires no utility grid to work on. And still, it can ensure constant and adequate electricity almost every single day of the year.

Significance of Off-Grid Solar Power System

Every solar system works by converting sunlight into electricity. A solar panel generates electricity as long as it absorbs sunlight. That means, there will be no power in the absence of sunlight (at night or in a cloudy atmosphere). Hence, to ensure a non-stop power supply at times when there is no sunlight, there must be a source available to store the energy. For people living in secluded regions, it is mandatory to have a solar power system with a solar battery. Off grid solar power plant is a system with battery bank. That means, it can store the energy generated by the system to be used for future needs. 

How Does An Off-Grid Solar System Works?

  • This type of power plant store unconsumed power in batteries, provided by the solar system. 
  • The addition of Solar Inverter allows this system to convert DC electrical current coming from the batteries into AC (alternating current). 
  • AC is the standard form of electricity for anything that “plugs in” to utility power and is the appropriate current for common household appliances. 
  • The stored energy serves as electricity when required. 

Conclusion 

 “If you don’t have electricity connection or a reliable grid and you want to store electricity, then an off grid solar power plant is system recommend for you.”

On-Grid Solar Power System

As the name suggests, an on-grid solar power plant operates with the grid. On grid systems are solar PV system that only generate power when the utility power grid is available. They must connect to the grid to perform its function. This type of solar power plant is ideal for those who want to reduce their electricity bill while investing less.

Significance of On-Grid Solar Power System

With an on-grid solar power system comes the option of net metering which is an opportunity to earn more. The excess power generated is supplied to the grid which provides credit in the electricity bill. Hence you can reduce your electricity bill while earning more. Since with this system, the consumer can access power from two different sources, 24*7 power supply is guaranteed. Besides, it is efficient enough to run any home appliance without any difficulty. And finally, it is easy to install, requires less maintenance and costs less than an off-grid solar system. In general, buying an on-grid solar system is a great investment.  

How Does An On-Grid Solar System Works?

  • The power generated in the daytime can be used instantly or sent to the main grid. This type of solar system will automatically send excess power to the grid when solar panels are overproducing.
  • During a power outage, the exported power is drawn back from the electricity grid.
  • Any excess power fed to the grid earns you money. You will get credited later for this through Net Metering system by Indian govt.

Conclusion 

“If you have a reliable grid but your electricity bills are high, then on grid solar power plant is recommend for you.”

Hybrid Solar Power System

The hybrid solar system is a technique that uses a collection of solar batteries that can interact with the main power grid. As a result, it reduces your electricity bill significantly and returns more than it costs over a while. Hybrid solar system or power plant is a combination of both above said solar system. We can say that, On Grid Solar System + Off Grid Solar System = Hybrid solar system.

Significance of Hybrid Solar Power System

A hybrid solar power plant is the most expandable system that is future-ready since it uses both a battery and the grid. With a hybrid setup, you can maximise power consumption while using less electricity from the grid. Hence, this system ensures a constant power supply while reducing your electricity bill. 

How Does A Hybrid Solar System Works?

  • It is an on-grid system with battery storage. 
  • Solar panels generate electricity in daytime and run your household load. Simultaneously, the extra electricity will be stored in the solar battery.
  • It is equipped with an unusual ‘smart’ inverter that transmits DC to AC from batteries.
  • When required, the inverter tracks AC between your home and the grid. 
  • Once solar batteries are fully charged the electricity then automatically exported to the utility grid.
  • This system allows you to take full control over power transfer.

Conclusion 

“Hybrid solar system provides you both the feature of on grid solar system as well as on grid solar system. If you want to store power along with export facility, hybrid system is best for you.”

Commercial Solar Power Plant

Commercial solar setups are large scale solar power plants. These commercial solar systems are high capacity PV system, generally installed for reduce electricity cost or for marketable purposes. Mostly, commercial solar systems are on grid systems that generate power when the utility power grid is available. They can send excess power into the grid when the solar panel is producing extra power than your consumption through net metering. You will be credited for this power in the future.

Concentrated Solar Power Plants

These solar power plants use lenses, mirrors and tracking systems to concentrate the sun’s energy. This way, the energy gets converted to room-temperature heat. This heat is used to run conventional steam turbines or power generating engines.

This is a superior setup since it uses TES technology to store power. The biggest advantage of concentrated solar power plants is that it is reliable and its cost can be predicted. 

Thermal Solar Power Plants

This is basically a heat dependent solar technology that was used in solar power plants. In this technology, the sun rays are focused to a point by using solar collectors so that appropriate high temperature can be obtain to generate electricity.

These kinds of solar panels have two main components namely reflectors to collect the sunlight and receivers to focus it. The heat generated by focusing the light rays produces steam in the fluid. This steam rotates the turbine to power the generator producing electricity. Its tracking system tracks the receiver to catch the sunlight throughout the day when the sun changes its position.
