What To Know Before Installing Solar Project

Installing Solar Project

Solar energy is being received with enormous excitement across the country. Many homeowners are even able to save almost 100% of their electricity bills thanks to their solar panels. No wonder the installation of PV systems has grown exponentially from just 5 MW in 2010-11 to a whopping 5000 MW in 2019-20. However, the installation of a solar project on your roof has certain prerequisites which must be met to ensure it works at the optimum capacity. In this blog, we take you through all the critical ones.

Can your roof support solar panels?

First things first, make sure your roof can provide the physical strength and stability to install solar panels and mounting structures which are typically quite heavy. Do not install the system unless your roof is firm. The possibility of your roof collapsing under the weight of the structure could cause serious injuries or even loss of life.

Is your roof the right shape and type?

The type of roofing you have also determined the possibility of installing a solar project. A tin roof with a sharp slope can pose serious challenges while installing the mounting structures and even then these might not remain stable. A terrace on the other hand can offer a great deal of convenience. Likewise, how much space is available on the rooftop is also crucial to consider.

Which direction does the slope of your roof face?

To generate the maximum amount of electricity, solar panels must face the sun for as long as possible. This makes the direction of the slope of your roof quite significant. The best placement for your panels according to most professionals is either south or west.

How efficient is your installation location? How much energy do you use?

The amount of power generated also depends upon the installation location. You would obviously want the sun to strike your panels for the most part of the day. But this also depends upon your energy needs from the solar panel. In case you rely almost completely on your solar panels for electricity, choose your location carefully. The technician should be able to help you find the right spot for the panels, and in case of prior installation, can also help move the installation to a different location.

How do you connect to the grid?

A number of things need to be taken into consideration with regard to your connection with the grid. These include the following:

  1. How long will it take to get the connection?
  2. Are you liable to pay any fee?
  3. Will your supplier enter into a net metering agreement for surplus energy that you feed back to the grid?

Solar installation at home or business could create a lot of confusion and dilemmas. The best way to get all your queries addressed is to contact the experts.

5 Reasons Why It Is Worth Investing In Solar For Companies

Solar power is becoming increasingly popular among companies in India. With the country becoming a proponent of solar energy globally, India’s total installed solar energy capacity has increased 19.3 times in the last 8 years. Many organisations are considering investing in solar energy and with good reason. For them, it’s a win-win situation. Energy costs make up for a large proportion of expenses for businesses, both big and small, and hence, cost-efficiency is always a critical goal. There is also the need to be socially responsible and include sustainability in brand ethos. Solar energy helps them meet most of these goals.

So, if you are considering making the switch to solar energy, it could be absolutely worth it.

5 reasons why solar energy is worth investing in

1. Reduced overhead expenses – Going the solar route can help companies save huge on energy costs. Since most of the things in a workspace, such as computers and electrical equipment, run on power, solar energy can help reduce dependency on erratic energy sources. The fluctuating prices of non-renewable fuels too will not affect you. You can let solar energy take over the majority of your existing energy sources. This way, you have more control over the quantity and cost of energy. 

2. Dependable power supply – Power outages are not uncommon in India and unreliable power supply can create interruptions in business. With solar power, you can expect a reliable and stable power supply. India’s total land area gets about 5,000 trillion kWh with most parts receiving around 4-7 kWh per sq. m. per day. Hence, with solar panels in place, you can generate sufficient solar energy to run your operations. 

3. Ease of maintenance – Installing solar panels in your workspaces can be an efficient and one-time investment. They are made from durable materials and can be long lasting. You can rely on expert solar panel EPC companies, such as VEMC, to help assess your energy requirements, check the available installation area, confirm the budget, and install the solar panels accordingly. 

4. Long-term savings – Solar energy helps save costs in the long run. You will need to make a one-time investment for the installation. Post that, you can start enjoying the returns on your investment. The maintenance costs are not exorbitant either. 

5. Sustainable and ideal for CSR – Investing in solar energy can help save the environment. You will be able to invest in a clean energy source, cause less pollution, and reduce your dependency on fossil fuels. Solar power also makes for a good investment to meet your corporate social responsibility (CSR) goals. This can help you stand out to your customers and investors as a green company with low carbon footprint.

Can You Remove and Reinstall Solar Panels?

When might you want to remove and reinstall your solar panels? The most common instances would be when you are fixing the roof or the solar power system, or conducting maintenance on the roof or other equipment located in the area.

Common Solar Panel Installation Problems - And How to Avoid Them


Fixing the Roof

Even some of the smallest roof repairs may require you to remove and reinstall part or all of your solar panels. This can make repairing the roof simpler, without risking damage to your panels. If you need to replace sections of the roof and require these to be removed prior, hiring a solar professional to do it would be a practical move.

Fixing a Solar Panel System

When repairing parts of your solar power system, removing the panels can provide additional space for a more thorough analysis of the whole system. Also, it is often safer to carry out repair work on the roof after removing the solar panels, in order to avoid compromising their safety.

Other Reasons

Other times that you might need to remove and reinstall solar panels could be when you need to repair anything in and around the rooftop. For example, fixing satellite dishes and electrical wires which are usually located on the roof may necessitate this, as may events like relocating your solar power system.

Should I Attempt to Remove and Reinstall the Solar Panels By Myself?

Do keep in mind that it can be quite risky to do so without the appropriate tools and expertise. Certain special equipment is required for the task and taking apart the panels without proper knowledge can nullify any warranties and contracts on the product. Also, removing and reinstalling solar panels entail a complex permission process that is best dealt with by a solar expert.

Time and Cost to Remove and Reinstall Solar Panels

The total time and cost of removing and reinstalling solar panels depend mainly on the solar expert you choose for the job, though they should be able to quote a base price to begin with. This can be over and above the actual costs of repairing the roof or solar power system; so be sure to factor that in. 

The repair work can take another day or more, depending on the extent of work that needs to be done. So, the entire project can take about three days to complete. Of course, major repairs may need more time.

Certain other factors may include the condition of the roof, the panels and the hardware, as well as the weather and site location itself. 

Removing and reinstalling solar panels is a complex task that requires substantial knowhow. VEMCO Solar, a solar energy company in Mumbai, offers end-to-end solutions and has enlisted channel partners with the Ministry of New and Renewable Energy, Government of India, for solar PV rooftop, small power plant system integrators, and installation.

What Is Solar O&M And Why Do You Need It?

In any industry, operations and maintenance (O&M) are a crucial part of keeping the system running properly and efficiently. The solar industry is no exception and solar operations and maintenance (O&M) services or programs are required in order to maintain a standard level of performance for a solar energy system.

Advantages of module level power electronics in O&M for commercial systems  | Solar Power Portal

Regular servicing helps you to optimize the productivity you get from your solar power plants while reducing costs for maintenance and repair. Compared to most other power generating systems, solar power stations are simple to maintain. However, you need to make sure that you invest in high-quality O&M which is carried out professionally. This is one of the most important ways to make sure that your solar power plant stays in good condition, does not experience unnecessary breakdowns, and runs at peak performance levels.

There are three main aspects to solar O&M — preventative maintenance, corrective maintenance, and condition-based maintenance.

Preventative maintenance (PM)

Preventative maintenance, as the name suggests, includes regular inspection and servicing of your equipment in order to avoid the system from malfunctioning, which can cause unnecessary losses in production. This kind of maintenance takes place before your solar power system has witnessed any sort of breakdown, and the upfront costs associated with it are usually low to moderate.

Corrective maintenance (CM)

Corrective maintenance pertains to corrective action required to be taken after your equipment has already experienced a breakdown. Although this strategy may not appear to cost much on the surface, there is a higher risk of component failure and potentially higher costs on the backend. That can otherwise be avoided more easily with proactive, preventative and condition-based maintenance.

Condition-based maintenance (CBM)

Condition-based maintenance is when your solar power systems are monitored using real-time data. This strategy places a high priority on optimizing operations and maintaining peak performance levels, and can even be done by third-party providers and integrators. However, it comes at a higher cost than the other two strategies of maintenance, but these may actually pay off because your system runs as smoothly and efficiently as possible.

So, it is safe to say that no matter which strategy you employ, solar O&M is a crucial aspect of your solar power system to ensure that it continues to operate at optimal levels at all times. Timely maintenance significantly reduces the possibility of breakdown and production loss. O&M providers like VEMC can offer planned maintenance schedules to optimize equipment performance and minimise downtimes. Additionally, creating an elaborate breakdown impact analysis of solar plant sites is necessary in order to prepare a priority matrix for spare management and better maintenance.

How Solar, Wind, and Hydropower can Outclass Coal Energy

For a very long time in modern human history, coal dominated the energy market as the cheapest, most easily available, and readily combustible source of energy. Coal energy was in fact the force behind the Industrial Revolution and continued to power factories, trains, and smelting furnaces, even into the twenty-first century.

However, today there is a huge concern to shift our energy demands from fossil fuels such as coal to renewable energy like solar, wind, and hydropower. This is due to the growing awareness about environmental issues and also the exhausting fossil reserves across the world. In the developed world, the transition is already evident, with shrinking demand for coal in the electricity sector. More and more power plants are switching over to solar and wind farms as the main source of energy to generate electricity. In the US, the Energy Information Administration (EIA) reported that the demand for coal in the electricity sector shrank from 28% in 2018 to 22% in 2019 (source).

As declining reserves of coal impact supply and leads to increased prices, renewable energy will be seen as a more cost-effective source of energy. This will draw the commercial sector further towards renewable energy as it will not just make them more compliant with their environmental legislation but also help them cut their energy bills and improve their margins.

India has set itself a target of producing 175 GW of renewable energy by 2022, out of which 100 GW will come from solar energy, 60 GW from wind, 10 GW from biomass, and 5 GW from hydropower (source). Increasing reliance on non-fossil energy is especially important for India to keep threats from climate change under check while its economy grows at a steady pace.

Critics take an interesting line of attack at renewable energy: The sun doesn’t always shine and the wind doesn’t always blow. This seems like a valid criticism but overlooks the stupendous growth of research and innovation in renewable energy (especially solar energy), backed by generous funding. This has greatly enhanced the storage systems so that the energy is used as and when needed. This has also placed renewable energy on the trajectory of increasing efficiency and declining equipment costs.

As fossils fade away into the background of the energy conundrum, renewable sources of energy like solar, wind, and hydropower will form the dominating portfolio for our energy needs of the future.

Types Of Solar Panels And The Best Fit For Your Commercial Needs

One of the foremost choices to make when it comes to procuring a solar system is with regards to the type of solar panel you wish to install. There are broadly three types of solar panels available and each differs from the other in terms of cost, efficiency and aesthetics.

Monocrystalline Panels

This type of panel gets its name from the fact that each cell in the panel has a single crystal of silicon which allows free movement of electrons through the cell, taking its efficiency upto 20% and more. High efficiency means lesser requirement for space and hence, these panels are best suited for residential use as space can be managed efficiently. Monocrystalline panels contain either 60 or 72 cells, depending on the size of the panel. The silicon cells are in the shape of black squares with their corners cut off, giving the panels a deep black aesthetic look.

Polycrystalline Panels

Multiple crystals go into making each cell in these panels which restrict the free flow of electrons through the cell. Their efficiency ranges between 15% and 17% but with increasing innovation in technology, this is expected to improve. Compared to Monocrystalline panels, these panels require more space and therefore, may be slightly challenging to accommodate in a residential setting. These panels also contain 60 or 72 cells but multiple crystals give them a marbled blue appearance, which may not be aesthetically pleasing. However, Polycrystalline panels are more affordable which, despite factors like space and efficiency, has enabled the product to make galloping strides even in the residential market segment in recent years.

Thin Film Solar Panels

These panels are solid black in colour and do not have any silicon cell outlines. Being lightweight and flexible, these are easy to carry and install. Thin-Film panels are the least energy-efficient (10-13% range) and are only suitable for large establishments like industries and utility solar projects with ample space. Being extremely cost-effective due to low energy efficiency and ease of installation makes these panels all the more suited for large-scale commercial establishments. These have a very short life expectancy and require frequent replacement. Depending on the material they’re made of, these panels can be both blue and black.

Future Of Solar Energy Looks Brighter Than Sunshine

Solar energy is clean, renewable, and can provide for a significant proportion of our energy requirements with the help of the latest technologies. According to International Energy Agency, it is, in fact, the cheapest form of electricity in history!

What’s the current state of solar?

According to Ministry of New and Renewable Energy, Government of India, India has achieved 5th position globally, in solar power deployment, and the solar tariff in India is very competitive and has achieved grid parity. The country’s solar power capacity has increased by more than 11 times in the last five years, from 2.6 GW in March 2014 to 30 GW in July 2019. 

If we succeed in improving production further, the energy systems like solar farms and CSP (concentrating solar power) plants would not only be considered as valuable energy resources, but also help create more energy than fossil fuels. It will also help reduce carbon emissions significantly.

Solar energy storage

The success of future energy systems depends on solar energy storage as it can store excess solar power onsite, which can be utilised later, when the sun isn’t shining. However, these systems have expensive lithium-ion batteries, which makes them heavy on the pocket. So, if the cost can be brought down and efficiency can be increased, the installation of these battery storages will become more commonplace in the future.

Floating solar farms

India is about to start work on the world’s largest floating solar energy project at Omkareshwar dam on the Narmada river. The project is expected to produce 600 MW solar energy starting 2022-23. A 100 MW floating plant is expected to become operational in Telengana soon. Spread over 450 acres, the project will have 4.5 lakh photovoltaic panels, and will be scalable in the future. 

Floating solar farms can help preserve land for agricultural and terrestrial ecosystems. It will also help countries that lack adequate land build utility-scale solar farms.

The future of solar panels: The Tesla Solar Roof

Going solar can reduce your electricity bill considerably. While rooftop solar installations are extremely beneficial, many may not like the way in which it changes the look of their homes. To solve this issue, companies like Tesla, are working on making the future solar panels more aesthetically pleasing, so that it could blend in with its surroundings.

Landowners and developers

Increased demand for solar energy can be a great opportunity for land owners, who can lease out their land for solar projects, in exchange for money. This would be a win-win situation for both property owners and solar project developers.

Solar energy is one of the most inexpensive and sustainable forms of power on the planet. With advancements in technology and encouraging government policies, we are all hopeful about a brighter future for the solar industry. That would also mean lesser pollution, reduced use of fossil fuels, lesser carbon emission, and a cleaner future for all of us. If you are keen on leveraging the advantages of solar energy, just contact us on +91 98199 07445.

6 Things to Ask Solar Consultant

It is really important to let your guards down and learn everything about solar panels before you plan to get one for your residential or commercial space. Well, having a direct chat with solar consultants might be your guide over here. As they are associated with this field for a pretty long time, you can expect to get quality responses to all your queries. So, let’s learn about the 6 things that you should primarily ask your consultant, especially from Vijay Engineering and Machinery Company (VEMC).

1.Don’t forget to ask about the Financial Options:

Can you benefit from that tax credit? Does the solar energy consultant have any lease option or competitive loan by his side for the clients? Most companies will push for the Power Purchase Agreement. It will make your solar contractor the electric company. It means you are not going to own the system and just need to pay for the power it produces for your place. But, the solar contractor has every right to raise the rates. That’s why another loan or leasing program with a 0 down and 0 increase guarantee is always important for most customers.

2. Ask to check their design centre:

If you want, the consultant can sees the company’s design centre or operation office. Avoid letting them meet you at your place. You need to know more about the company and its precise workflow because you proceed further and get panels from their sides. When you have experienced groups like Vijay Engineering and Machinery Company (VEMC), you don’t have to worry much. With 72 years of experience, you can expect only the best from this source!

3. Ask for expansion of solar energy system in future:

This is another interesting point for you to jot down whenever you are dealing with the solar panel consultant for your queries. Ask them if they can expand the current solar system later if the need arises. With some countries becoming less dependent on fossil fuel, the consumers need to know if they can create a larger system in the near future for accommodating the power needed for their devices.

4. Ask more about the panels:

You should ask the consultant about the solar panels they are planning to install at your place. Always remember that not all panels are the same. Some are more durable and efficient than others. Experienced companies like Vijay Engineering and Machinery Company (VEMC) are able to produce around 75% more energy over the course of their working period. So, always research the panels through one third-party source to ensure that the products will last long.

5. Ask about the benefits of working with them:

There must be some benefits involved while working with a local solar contractor over a national brand. So, do ask about those benefits before you get yourself involved with their solar panels. Vijay Engineering and Machinery Company (VEMC) is one ISO 9001:2015 certified firm and a pioneer in the field of electromechanical engineering items, allied equipment, and all the necessary services. This company is CRISIL MSE-1 rated. They are known to present strategic expansion and consistency throughout for providing excellence in service, quality of product, and leadership. So, working with this team will save you a lot of money and time!

6. Ask if moving towards solar panel is a good call for you:

Well, the answer to such a question can be a complex one. It depends on multiple physical factors. How much are you currently paying on your electric bill? How much shade does your roof actually get? Why are you looking for solar panels? Is it because of the financial benefits or anything else? Make sure to get these questions answered first before you can opt for the solar panels.
