Factors affecting Solar Plant Price


When we talk about the cost of solar plant, we miss out on various factors. There are many things which are needed to be considered before determining the solar plant price. A solar plant of some particular capacity can be installed from a cheap to expensive range. It all depends on quality, design and brand choice of various components in a solar plant. A detailed discussion on factors affecting solar plant price is given below.

All the parameters should be carefully determined and a solar plant should be designed carefully to get the best price for all the requirements and needs.

Factors affecting Solar Plant Price

Various factors affecting solar plant price in India are described below.

Type of Solar Plant Technology

There are primarily two technologies available in Indian market for Solar Plants. You can choose any one of these depending upon your needs. The solar plant price in India depends largely on the type of technology you choose. A brief on these technologies, is given below:

Grid-Connected Solar Plants

Solar plants which are directly connected to the grid and can import and export energy from and to the grid are called grid-connected solar plants. These plants are also called On-Grid Solar Power Plants or simply, On-Grid Solar Plants. These solar plants do not contain any storage devices, such as, batteries.

Government of India provides a subsidy on these solar plants for residential sector and an accelerated depreciation tax benefit for commercial or industrial sector.

You should choose this technology, if you receive regular uninterrupted electrical supply. However, a few hours cut occasionally can be avoided and you can still choose this technology. Otherwise, you should go for Off-Grid Solar technology briefed next.

Since, these plants do not contain any storage devices and government provides subsidy on them, these plants are cheaper than Off-Grid Solar Plants.

There are various benefits of on-grid solar plants. To learn about them, click here.

Off-Grid Solar Plants

Solar plants which may or may not be connected to the utility grid but contain batteries for backup are called off-grid solar power plants. Sometimes, a diesel generator input is provided in place of utility grid to charge batteries in the absence of solar energy and grid.

You should opt for this technology, if you live in an area having insufficient electricity supply or the electricity is unavailable.

In these plants, cost may also depend on the designing of this system for various backup requirements.

Similar to On-Grid Solar Plants, these plants also have their distinct benefits. To learn about them, click here.

A fair comparison between these two technologies can be a good source of information for a consumer in order to decide which technology to opt for. To read the comparison of these technologies, click here.

The choice of technology of solar plant is the most important factors affecting solar plant price.

Type of Solar Panel Technology

There are two types of solar panel technologies mostly used in the Indian market. These are:

Polycrystalline Solar Panels

Polycrystalline solar panels are made from silicon. They are made by melting many fragments of silicon together to form the wafers for the panel. Therefore, these are also called “multicrystalline panels”.

This is currently the most used solar panel technology in India and also the cheaper one of the two.

Solar Plant Price in India will be less, if you choose this technology.

Monocrystalline Solar Panels

These panels have cells made from single crystal of silicon. These are more efficient than the polycystalline solar panels. The affects on efficiency due to temperature variations and environmental conditions are less in these panels as compared to polycrystalline panels.

These panels are a bit costlier than polycrystalline panels.

Choice of solar panels is one of important factors affecting solar plant price.

Type of Battery Technology

This factor comes into play for off-grid solar plants with battery backup.

There are various technologies of batteries available which vary in cost. There are lead-acid batteries and also maintenance free batteries such as Li-ion batteries. Many other type of batteries are also available. Some of these are listed below:

  • Lead Acid Batteries
  • Tubular Batteries
  • Tall Tubular Batteries
  • Flat Plate Batteries
  • Lithium Ion Batteries

These batteries are based on different technologies and provides various distinct advantages unique to them. You can choose from any of these battery technologies depending on your requirements and budget.

When installing an off-grid solar plant with battery backup, this becomes an important factors affecting solar plant price in India.

Type of Structure used

There are various types of solar structures employed for various roof types and requirements.

Solar structures are designed according to the roof of the consumer. There can be various types of roofs such as, RCC, asbestos, tin shed etc. Structures are also designed on the basis of requirements such as height of the structure etc.

This is an important factor while considering a solar plant. This is an important factors affecting solar plant price.


There are many more components which together affect solar plant price in India.

In case of an off-grid solar plant, type of charge controller also plays a role in determining the the cost of solar plant. In some configurations, charge controller in external while in some it is in-built in the inverter.

Length of wiring, number and size of earthings and monitoring system are also some of the important components of a solar plant which may affect the price of solar plant in India.

Location also plays a role determining the cost of a solar plant.

All these are important factors affecting solar plant price.

Choice of Brand

There are a variety of brands available in the market for solar panels, inverters and batteries. They offer a wide range of products differing both in terms of technology and cost.

Different brands offer products which may vary in technology, service support, cost and quality etc. A lot of offerings are available in Indian market at various price points. You can get government subsidies easily on Indian brands as compared to international brands. This also affects the cost of solar plant. You can choose any one of them depending on your liking and budget.
