From Solar Rooftop Calculator To Basic Parts, Here’s What You Need For A Commercial Solar Plant


We can all agree that having access to electricity is essential. It is necessary for a variety of domestic, professional, and industrial requirements. These applications all require the use of a suitable electric power supply. Hydropower, thermal power, and nuclear power are common ways to produce electricity.

Due to the renewable nature of the primary source of energy, other techniques of generating electricity, such as solar and wind power, are growing in popularity these days. A typical method to produce electricity generated from solar radiation is to set up a commercial solar power plant in India while utilizing software like a solar rooftop calculator.

An operational solar power facility In a conventional solar power plant, a bank of solar panels collects sunlight and uses the photovoltaic (PV) effect created by the PV cells in the panels to transform it into DC electricity. After that, a battery receives this DC current and stores it all. An inverter converts this DC electricity to AC power, which is then delivered to the mains and used to power a variety of applications.

To ensure that the solar power plant’s investment is properly utilised, a layout suitable for commercial use must be carefully prepared. When building a commercial solar power facility, the following factors should be taken into account:

Required Results

The first thing to determine is how much electricity is required to operate the different machines and pieces of equipment in the company. This is crucial in figuring out how many solar panels are needed to supply the establishment with the necessary amount of electricity. Calculate the daily load average in watts to get started. Additionally, the kind of power needed—single-phase, three-phase, AC, or DC should be determined.

For instance, if a solar panel can generate 300 W after just one hour in the sun, it may generate 2400 W after eight. This information will be useful because it shows that this solar panel can produce 2.4 kWh in an 8-hour day, which is sufficient to run the lights and electrical appliances in a typical Indian home. On the other hand, commercial applications would have a bigger need and more panels. 100 solar panels would be required to power a solar power plant if a modest facility needs 240 kWh of electricity every day.

The total space needed to accommodate 100 panels is 2100 square feet if each is 77 × 39 inches (or roughly 21 square feet). Furthermore, the rooftop or garden needs to be able to support around 2 tonnes of weight in total because each solar panel weighs about 50 pounds.

This is important since the cost of solar panels makes up between 50 and 60 per cent of the total cost of a commercial solar power plant.


A battery or batteries linked to the system can be charged using the power produced by the solar panels. The lead-acid battery, which is available in two voltages (6 V and 12 V), is the most often used kind of battery. Using a solar rooftop calculator, this power of the same is estimated.


Solar power plants produce DC power from solar panels; however, this DC power must first be converted to AC power before it can be used to power various machinery in a commercial space. This requires the use of an inverter, and the power delivered must meet the voltage and frequency specifications of the machinery and equipment within the industrial unit.


To ensure the necessary electric power, the various solar power plant components must be connected using the proper cables, various types of switches, fuses, protective devices, and earthing cables. The output of the solar power plant can be fed into the mains of a commercial building to provide whenever needed electric electricity.

Commercial solar power plants can be classified as on-grid, off-grid, or hybrid, each of which can be customised to fit particular requirements.

The on-grid variety works with the grid’s AC power supply. During the day, this system is powered by a solar power plant, and when that supply is insufficient, it is powered by the grid. By using net metering to deliver excess power to the grid, this technique also enables revenue generation.

The off-grid system is independent of the grid. When the grid supply is spotty or nonexistent, this is advantageous.

Both off-grid and on-grid technologies are combined in the hybrid system. This has many advantages, including providing backup power and earning money when extra power is supplied to the grid.

As seen above, there are several factors to take into account while building a commercial solar power plant in India. When building a solar power plant, it is essential to consider each of these criteria because they all affect how much commercial solar panels cost in India.
