Solar panel installation can seem like a daunting investment. The upfront costs can in fact be the most significant deterrent against taking the solar option. However, with the right guidance, you can save plenty of money while installing your solar panel. VEMC is the leading solar energy company based out of Mumbai.

In this blog, we explain how you can save big on your solar panel installation

1. Government incentives

Governments across the world are trying to promote solar energy to shift their country’s reliance on conventional fossil fuels. By providing incentives to homeowners, they make the investment in solar energy an attractive prospect. India’s Rooftop Solar Programme by the Ministry of New and Renewable Energy is one initiative to exhort residents to invest in a solar rooftop system. To put things into perspective, solar energy systems of up to 3 kW are eligible for a subsidy of up to Rs. 14588/kW.

2. Financing options

Solar financing is another feasible option for homeowners who do not want to spend a huge sum on the installation upfront. This allows them to spread out the cost of the panel over a larger horizon. A number of private and public sector banks in India are offering solar loans at affordable interest rates of around 8%.

3. Select the right solar system

Make sure you’re selecting just the right size and type of solar panel system for your rooftop. For residential homes, 3-5 kW solar panels should be enough. Also, make sure you’re choosing a good quality solar panel system that helps you save energy in the long run. Monocrystalline solar panels typically offer better efficiency.

4. DIY installation

To save on your installation labor, you could perform a DIY installation. These days, a lot of resources like guides and tutorials are available online, which homeowners can use to install their panels. However, in the case of complicated rooftop design, unsafe mounting areas, or lack of the right tools, it is always better to rely on experts. 

5. Proper maintenance

Regular and timely maintenance is important when it comes to extending your savings. When solar panels are regularly inspected and maintained, the costs of sudden breakdown go down. Dust, ash, or other particulate matter can bar the sunlight shining on the panels, thus reducing their productivity. Frequent surface cleaning can significantly improve the efficiency of your solar panels.

6. Long-term financial benefits

At any rate, choosing to install a solar panel can never be a bad financial decision. As any solar installation company would explain, the average payback period for residential consumers on their solar installation is around 4-5 years. This indicates how financially beneficial solar panels are in the long run. The savings incurred on energy consumption by far exceed the upfront costs of the panels.
Investing in solar panels can seem quite daunting, given the huge cost structure upfront. However, with the right choices, you can actually maneuver your way to great savings on your panels.

7 Essential Checks for Metal Roof Maintenance in Solar Plant Systems

Solar Plant Systems

To make sure your solar rooftop system offers optimum efficiency, you must have a robust maintenance regime in place. Proper inspection and maintenance also help improve the working life of your panels and reduce the costs of depreciation and sudden breakdown. These services are often provided by the same solar energy company that you procure your panels from. 

In This Blog, We Tell You About The 7 Essential Checks That You Must Perform To Ensure Proper Maintenance Of Your Solar Rooftop System:

  • Roof Inspection

Before Solar Panel Installation, make sure your roof would be able to withstand the burden of the mounted solar panels. In case the age of your roof is ten years or more, it is advisable to get it replaced before installing a solar rooftop system. Also, check for any seepages or leakages in the roof. 

  • Cleaning and Debris Removal

Check for any debris in the inverter pad area or elsewhere. Look for any signs of animal infestation such as excreta etc. all over the system and clean it regularly. Wipe the panel surface regularly to remove dust particles that can reduce the output.

  • Gutters and Drainage System

The solar rooftop system must have adequate drainage. Check for any water pooling on the roof and ensure that the drainage is seamless. Any water seeping into the system can cause damage to the equipment, and water on the panels can reduce their efficiency.

  • Sealant and Waterproofing

Mounting a solar rooftop system requires drilling multiple holes into the roofing. This makes waterproofing of the roof essential. This is done by using waterproofing membranes that seal cracks, crevices and seams. For long-term reliability, make sure the waterproofing has been done by a reputed roofer. 

  • Rust and Corrosion Prevention

Rusting can affect the electronic circuits of your solar panels reducing the electricity generated. Besides, corrosion on the outside brackets or racking system can weaken the structure on which the Solar Rooftop System is mounted. Check for rust regularly, use metals that are rust-proof such as anodized aluminium or stainless steel, and ensure complete waterproofing. 

  • Solar Panel Mounting

This is a more physical aspect of the solar panel system. Having a robust mounting structure is necessary to prevent damage to not just your panels but also to avoid accidents and injuries. A weak mounting can lead to the sudden collapse of the entire solar panel installation, which is otherwise expected to last up to 25 years.

  • Structural Integrity

Solar installations must be structurally sound and secure. Check whether the mounting structures are made of durable and corrosion-resistant material. These days, a number of mounting structures with high standards of reliability are available at competitive rates. Look for the warranty provided by the company, strength grade and coating, and the weight that it can support.

Here are a Few Ways to Make Your Solar Installation Absolutely Safe & Secure

Safe And Secure Solar Installation

Solar energy is the future and a lot of homes are opting for it hoping to cut back on their electricity bills and receiving an uninterrupted power supply. But solar power installation must be done with a number of safety prerequisites in mind. The best solar company will take into account all factors like your building infrastructure like space or roofing and electrical connections before installation.

From the Electrical Point of View:

Before getting in touch with a solar energy company, track and keep a record of your monthly bills and the power drawn by your electrical appliances. You can do this using the energy calculator apps online. Usually, the monthly consumption in a typical urban household is 1-5 kW. Depending on your electricity needs, choose a solar power system of the right size. Standard solar panels have a 250 Wp (Watt peak) configuration, while larger panels can go up to 300 Wp depending upon the requirement.

Make sure the installer is connecting all the electrical wiring carefully and without leaving any glitches behind. A qualified engineer must supervise the process of routing the cables and it must be ensured that the cable is not damaged. Never touch the electrical wiring or contacts without proper protection gear or insulation.

The PV cells generate electricity by converting the sun’s energy, and the inverter converts the Direct Current (DC) from the panel into Alternating Current (AC). In case the components are “live” with electricity generated from the sun, they can cause an arc-flash electricity shock leading to severe injury or death. Make sure the system is properly earthed to prevent any such situations.

Make sure your solar power company is doing enough to protect your cables, say by using a flexible metal conduit when wiring through walls or if they are exposed to sun and rain outdoors.

Identify the Roof Structure, Type, and Material of the Roof:

Before you go for solar power installation, ensure that your roof offers ample space, has the right structure, and is made of robust material. Otherwise, mounting a heavy solar panel system can cause serious damage to your roof and accidental injuries to your family. Roof space is one of the primary factors to consider in metros, and is given the highest importance for instance by solar EPC companies in Mumbai.

The best roof for installing solar panels is a composite asphalt shingle roof. But by and large, solar panels are viable on most roof types except for wood shake roofs. The roof must ideally face south but in a country like India, as long as you have space for the panels, you’re good to go. Most places receive ample sunlight during the day irrespective of the direction of the roof.

When it comes to the ideal roof design for solar panels, the only rule is ‘simpler the better’. Roofs with lots of tiers, pipes, chimneys, and skylights can complicate the installation effort manifold.

If your roof is old or dilapidated, make sure you replace it before the installation. The old roof may not just be dangerous, it will cost double to dismount and then remount the panels when you eventually plan to replace it.

Pump Energy Audit Leads to Substantial Savings

Pumps are an essential resource for several verticals such as the industrial sector, the hospitality sector, the agriculture sector, and the medical sector. As a result, they are extensively used in operations across industries. This also means that they consume a lot of energy to run efficiently. For example, in agriculture, groundwater pumping consumes about 16×109 kWh of electricity and about 2,000 million litres of diesel oil in a year. 

Pump energy audits reveal that around 30-50% of the total energy consumed from pumps can be saved. This means that if you replace your old pumps with new, efficient pumps, you can not only save energy but also significant energy costs. With rising energy prices, getting an energy audit done by professionals is a prerequisite. 

What is a pump energy audit? 

A pump audit is an energy optimisation audit of your pump system. It helps analyse the efficiency of your pump system and identifies energy-saving options through switching to a new pump or pump line. Additionally, it also illustrates the monetary benefits of the switch for your company. 

There are several reasons why your pumps can have lower efficiency:

  • Undersized pipes (less initial cost but high frictional head loss and operational cost)
  • High delivery point (excessive height increases energy consumption)
  • Poor fittings (leads to leakage and losses)
  • Inefficient pumps (due to improper selection and mismatched prime movers)

Benefits of a pump energy audit

Investing in an energy audit can be beneficial for your company as well as the environment. Here are the advantages of energy optimisation for your organisation: 

  • Reduced energy bills (up to 40%)
  • Lower operating costs
  • Low pump failure rates
  • Shorter payback periods
  • Reduced need for fuel imports
  • Conservation of insufficient resources
  • Building a sustainable environment

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.


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.


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. With over 72 years of industry experience, VEMCO Solar was able to execute the Godrej City project successfully. VEMCO Solar is a market leader in solar solutions — be it solar plant erection, procurement, commissioning, net metering, or electrical connections.

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.
