Solar Success Story: The Installation of 200 kWp Plant at Godrej City

Navi Mumbai is a rapidly developing area, where new properties are being built. Godrej City is one such project by Godrej Properties. Located in Panvel, Navi Mumbai, it offers skillfully designed 1 BHK, 2 BHK, and 3 BHK apartments that are currently under construction. Godrej City consists of 568 units across 18 floors, spanning more than 3 towers over a total project area of 150 acres. Being a well-established solar energy company in Navi Mumbai, VEMC was consulted and hired to install a 200 kWp grid tied solar power plant at this location.

Challenge

Godrej City, being a booming residential estate, was seeing extremely high levels of electricity consumption. In fact, the annual average electricity production was 260000 kWh. VEMC’s solution sought to bring this down significantly and provide a greener, more sustainable and efficient source of energy.

We were met with the challenge of installing solar modules on “sandwich” roof profiles that don’t allow penetration of the sheet when anchoring the solar mounting arrangements. 

Further, this took place during monsoon and the COVID-19 pandemic. We were working at the site with our teams through this and all precautions had to be taken to ensure our safety. 

Our Solution

We took on the challenge and set about working out a solution. The project was a 200 kWp grid tied solar system. A grid-tied solar system is connected to the electrical power grid. The system relies on this grid to produce solar energy which can be used and funnels the excess energy to be used at a later time, or for net metering or clean energy credits.

The solar plant we successfully installed consists of 514 units of 390Wp high-efficiency Mono PERC modules. 

We solved the problem posed by the sandwich roof profiles by using high-strength industrial metal to metal adhesives to connect the mounting arrangement and roof.

The team was equipped with PPE kits and a thorough set of safety harnesses. This may have slowed them down but it protected everyone from both COVID-19 and other accidents.

Impact

The amount of carbon dioxide saved each year by avoiding fossil fuels to generate the same amount of energy is 184 metric tons! To get a clearer picture of the impact, this is equivalent to:

  • Greenhouse gas emissions from 40.1 passenger vehicles driven for one year and 463,075 miles driven by an average passenger vehicle
  • Carbon dioxide emissions from 20,733 gallons of gasoline consumed, 18,100 gallons of diesel consumed, 203,657 pounds of coal burned, and 2.4 tanker trucks’ worth of gasoline
  • Carbon sequestered by 3,047 tree seedlings grown for 10 years, 226 acres of forests in the USA for one year, and 1.3 acres of forests preserved from conversion to cropland in one year

The project expected payback is approximately 3 years, taking the maintenance expenses into consideration. VEMC is a well-established solar power plant company in India.

How Solar Panels Produce Electricity

Solar energy is one of the most promising sources of electricity owing to a number of inherent factors. Unlike conventional sources of energy like fossil fuels, solar radiation is abundantly received in most regions of the world. Electricity generation by solar requires little to no inputs of raw material and perfectly fits the bill for clean energy. But what is the science behind tapping solar energy? How exactly do solar panels produce electricity and how efficient is solar energy really? In this blog, we simplify the working principles behind solar electricity and elucidate your understanding of this magnificent fuel for the future.

Solar panels are made up of a number of Photovoltaic (PV) cells (named so because they convert solar energy into electric energy). The PV cells are made up of semiconductor materials such as silicon that absorb solar radiation and release a number of electrons, which then travel freely in the cell. To create an electric field when sunlight hits the panel, a positively and a negatively charged semiconductor is sandwiched together. The electric field directs the flow of the loose electrons towards the conductors lining the cell, which then flow through the wires as Direct Current (DC). 

The DC then reaches the inverter that converts it into the most commonly used Alternating Current (AC). Finally, a wire carries the AC from the inverter to an electric panel which acts as a junction for distributing the current throughout the building.

One PV cell typically generates two watts of electricity. However, when a large number of PV cells are connected together on a solar array (PV panel), hundreds or even thousands of kilowatts of electricity can be generated. A PV panel is made up of solar cells arranged in the configuration of 32, 36, 48, 60, 72, or 96 cells. The larger the assembly, the greater will the electricity produced be! The standard panel size for commercial use is 77 x 39 inches, while that for residential purposes is 65 x 39 inches. 

The energy efficiency of most PV panels ranges from 15% to 20% at present. This is affected by varying solar radiation received at different geographical locations. Sunlight also varies according to the time of the day and seasons of the year. Besides, obstruction, shade and unclean panels can also reduce production significantly.

The principle behind solar energy is quite simple. However, there’s still ample scope for advancements in order to boost production capacity and enhance efficiency. This demands generous funding in the field to promote research and innovation. For more information on various types of solar services, feel free to contact us on +91 98199 07445.
