What You Should Know About the Lifespan of a Solar Panel

Solar Panel Life

Spoiler alert: It’s good news.
One of the countless benefits of installing solar PV Panels is that once invested in, they last for 20-30 years with minimal maintenance. But before you invest in them, it is important for you to know everything about the lifespan of this source of Renewable Energy.

What does ‘lifespan’ refer to?
When we say the Life of Renewable Energy, in this case, is 30 years, it doesn’t mean that your solar panel will stop working after 30 years. It simply means that it won’t function at optimum levels. The panel will still continue to work for many more years.

Solar panel degradation rate
So now we know that a panel may not be 100% efficient after a few decades. But at what rate does it degrade? That depends on the quality of the panel you choose. On average, Solar PV Panels degrade at a rate of 0.5-0.8% per year. This means that if a panel is operating at 100% efficiency, this will drop to 99.5% or 99.2% respectively after a year. This isn’t a cause for worry because your panel will still work fairly efficiently for decades. At this slow a rate of degradation, you’re in for many decades of hassle-free Renewable Energy generation.

How to Determine if Your Solar Panel Needs Repairs

Vijay Engineering And Machinery Company - Solar Panels

Repairs? You may be surprised. Solar panels are known to be very low maintenance, however, it’s always prudent to check up on them at least once in six months to ensure that nothing stands in the way of efficient renewable energy generation.

What are some signs you need solar repairs?
Dirt buildup. This is the simplest thing to look for. Since your panel is outdoors, it is subjected to dust, debris and other pollutants. These could obstruct sunlight reaching your panel, and in some cases, may also cause damage to the panel if not dealt with properly.
Damaged glass. The glass used on PV Panels is built to withstand the harshest of conditions. However, in rare cases, as a result of heavy objects falling on your panel, you may notice cracks on inspection. Here, it’s crucial to get them fixed to avoid further issues.
Damaged metal parts. The panel is supported by a rack and several smaller parts that hold it in place. While these are designed to last for years, over time, they may begin wearing out. If you notice rust on any portion of the rack, your panel needs immediate repairs.

Leave the repairs to the experts

7 Ways in Which Solar Energy Benefits Us

We’re always told solar energy, being Renewable Energy, is good for us. But how?
As Global Warming is on the rise, the Earth is exposed to more sunlight and heat. PV Panels make use of this adversity to generate electricity. Apart from this, there are many other benefits to using solar energy.

1) Saves Oil: In many places, crude oil serves as the main source of energy. With rising oil prices, solar energy can be easier on the pocket in addition to being a greener energy source.
2) Creates Employment: The installation, maintenance, commissioning, etc. of PV Panels, Batteries, etc. can generate a lot of employment.
3) Equivalent to Taking Cars Off the Roads: Fewer cars lead to a fall in greenhouse gas emissions. Similarly, using a Residential Solar Panel reduces demand for Non-Renewable Energy sources that emit greenhouse gases. As a result of this, the emission of harmful gases like carbon dioxide, carbon monoxide, etc. is significantly reduced because solar PV systems don’t release any greenhouse gases.
4) Equivalent to Planting Trees: Planting trees helps absorb excess carbon dioxide from the atmosphere. Solar energy, on the other hand, prevents carbon emissions by substituting Non-Renewable Energy. Hence, the two have the same effect.
5) Reduces Health & Environmental Damages: Solar energy is clean energy and doesn’t produce any harmful by-products. This makes it a safe form of electricity.
6) Saves Water: Coal power plants use vast amounts of water to process and clean the fuel. Solar energy generation, meanwhile, doesn’t need any water since the “fuel” is sunlight.
7) Reduces CO2 Emission: Since solar power generation doesn’t burn any carbon-based fuels for energy, it doesn’t emit any carbon dioxide.

Basic Understanding Of Industrial Water Pumps

The thing with fire fighting pump set is that they are basically meant to work at one point only. This means that such a pump has only one point of flow and head. This can be described as a hydraulic condition. It is also referred to as BEP (Best Efficiency Point) as well as the best operating point. It may have a published set of curves. However, as experts would tell you, this is merely a commercial compromise. For most end-users, the process of getting a pump built and designed to suit their special hydraulic conditions would be really expensive.

Paying attention to the published curves of the pump

Even if you have bought Kirloskar water pumps India this is something that you must do. The pump performance covers of the makers are based on clear water. The approximate mark here is 65 F. This is unless something else has been stated by the makers. You can be sure that they would not be corrected with respect to fluid viscosity. Even when they have started a horsepower it may or may not be corrected for specific viscosity and gravity.

If the published pump curve stops it is for some good reason

If centrifugal pump distributors have published a particular pump curve and if it stops at some point of the head and flow there is definitely a good reason for the same. You should never operate your pump at the end of the curve. If the pump was capable of producing a better performance the makers would have extended the curve themselves. If you operate it till the end of the performance curve or near you can be sure you would be facing issues in the future.

Pumps can be stupid

As the best water pump dealers in Thane would tell you, these pumps can be rather stupid. You need to understand that a centrifugal pump is basically a machine. It has a certain set of fluid properties, operating speed, and impeller geometry. It is because of these characteristics that it would react a certain way to the system that has been installed. The flow and head point of the pump will be a crossing point of its system curve and performance curve. The system curve would basically dictate where these pumps would operate. 

You have to understand the system curve

The system curve can be said to be representative of all the friction as well as the pressure and static head that has been baked into the same.  

A fire-fighting pump set will also have a velocity head. However, under normal circumstances, it would be so small that you would not really be concerned about it.


Your pump would never suck fluids. This is a misunderstanding that is surprisingly common. You need to understand that there has to be another energy source that would be needed in order for the liquid to get to the pump. Normally, the best examples of such sources of energy are atmospheric pressure and gravity.

Choosing Right Pump For Fire Hydrant And Sprinkler Application

Metro cities are getting filled with people seeking to make their dream come true and in an effort to do so, few succeed and looking at their success stories more people are coming towards metros, with increase in the population there is demand for housing. Metros like Mumbai have limitation in growing horizontally which leads it to the vertical expansion. It has become common to see 50 to 60 floor building and few of them touching almost 100 floors. This means developers in cities like Mumbai are focused on effective use of the space they have and don’t want to waste any of it.

This shift can also be seen in the pumping industry, where most of the builders used to procure standard horizontal end suction pump or split case pump are now shifting to Vertical pumps which consumes less space compared to horizontal pumps.

There are two major applications in Building and construction sector.

  1. Fire Fighting pumps
  2. PHE pumps (Public Health Engineering)

In Fire Fighting application the flow rate usually are 1620 LPM, 2400 LPM, 2800 LPM, 2850 LPM & 3200 LPM and Pump Head could be anything above 70 Meter

In PHE the flow rates are not as high as fire fighting application and the pumps required have to be of high efficiency as they are one of the continuously running equipments in any building. The requirement for compact size and high efficiency than single stage end section pumps for the same head and flow, Inline pumps are in demand for PHE application.

To cater High flow rate at high head we use pumps which are manufactured by casting process which offers extremely good pressure handling capability for the flows of fire fighting application, PHE pumps are of low flow which can be catered by pumps which are made from sheet metal. These sheet metal pumps are mostly Inline type.

While choosing pumps for Fire Fighting Hydrant & sprinkler application, people tend to confuse vertical multistage pumps with Vertical inline pumps but they are completely different and as per IS 12496 standards Inline pumps are not suitable for Fire Application except jockey pump application where the flow rate is 3% to 7% of total Flow.

High-Performance Fibre-Reinforced Composites for Sustainable Energy Applications

Today, thanks to the numerous advancements in technology, renewable energy is being redefined and is being made more affordable. One such upgrade is a fibre-reinforced solar power system. It is a system where the regular, flat PV Panels are substituted with ones made from glass fibre and composites.

A Solar Panel in Maharashtra would offer various benefits if it’s of this kind. Its main advantage is the fact that it produces higher amounts of electricity at a lower cost. Its installation would also require lesser capital investment.
Other key benefits include:

Durability: These panels are more durable than ordinary PV Panels. This is important if your premises are located in relatively harsher environmental conditions.

Weight: These panels are lighter than regular Residential Solar Panels which are often non-composite. This makes installation easier and ensures that your solar power system gets commissioned faster. The fact that it’s lightweight also makes maintenance easier.

Heat transfer: Along with contributing to the generation of Renewable Energy, these panels also absorb and transfer heat directly from the Sun. This could be helpful in relatively colder places and it also reduces energy wastage.

Solar and Wind Energy: Are They Really Killing Coal, Nuclear and Grid Reliability?

We’ve always been taught about the importance of using Renewable Energy. Solar and wind energy today power countless homes, offices, industries, etc. But are these sources of clean energy eliminating coal, nuclear and grid reliability? Let’s find out.

Solar and wind energy v/s coal

Can a Residential Solar Panel or a Wind Mill be a good substitute for coal? Absolutely. In fact, though these renewable energy sources may need you to incur significant capital expenditure initially, you’ll notice that you’re paying way less for electricity every month.

Also, recurring costs for solar and wind energy are limited to their maintenance, which can be made easy through Annual Maintenance Contracts (click here to know more about VEMC’s AMC offerings). Meanwhile, energy derived from coal involves higher recurring costs, i.e. the cost of mining it, burning it, etc. Hence, people are increasingly choosing Renewable Energy over coal.

Solar and wind v/s nuclear energy

Solar and wind energy can’t compete with the sheer volume of energy that can be generated with a nuclear power plant. However, these energy sources are more accessible, cheaper, safer and can be commissioned way more quickly. Thus, for homes, offices, commercial spaces, etc., PV Panels or Wind Mills can be more suitable.

Solar and wind v/s grid dependence

If the right form of energy storage is used (click here to know more about energy storage), solar and wind energy can eliminate the need for you to depend on the grid for your power needs. This can significantly reduce your electricity bills and rid you of power fluctuations that may occur in the grid. However, solar energy can also be grid-tied (click here to know more). Here, you can produce your own energy and also depend on the grid to absorb excess energy you produce. You can also draw energy from it if there’s a shortage.

Energy Storage Is Starting to Revolutionise the Electricity Industry

Renewable Energy, for instance, solar power, comes with some challenges. One of these is the fact that at any given point, one can’t be certain of how much energy can be generated. For instance, a cloudy day can reduce the energy supply and there isn’t much we can do about that.
Solar energy has the disadvantage of unpredictable supply since it depends on the natural environment, unlike non-renewable sources of energy. What can be done to combat this drawback? Energy Storage is the solution here.

How does Energy Storage work?
Energy Storage equipment like Solar Batteries can be used to deal with the inconsistencies of energy supply. They are connected to Solar PV Panels and store excess energy produced during periods of peak sunlight. This excess energy is then drawn from the Battery Backup and used to generate electricity during periods when it’s not sunny, e.g. nights, cloudy days, etc.

Why is Energy Storage important?
If you’re intending to install Solar Panel in Maharashtra, energy storage would be a good investment.
• It helps ensure excess electricity doesn’t get wasted
• It provides electricity when energy supply is low
• It can be used to transfer energy

Energy Storage and Solar Power Solutions:
Energy Storage is important in an off-grid solar PV system (click here to know more about this system). Here, since the system isn’t connected to the main power grid, Solar Batteries are required to supply power when sunlight isn’t available. Similarly, Energy Storage is also needed in a hybrid system (click here to know more).

Energy Efficient Pumps – A Need Of Modern World

India is a country that is urbanizing and that too at a rapid rate. Experts expect that by 2030, 40 per cent of the country would become urban. One of the immediate aftereffects of this rapid urbanization has been the increase in the high rise building complexes. In most of these urban centres, the local municipal corporations distribute the water. In these cases, they use pumps in order to push the water. The people living in these buildings store them in overhead tanks. These complexes are becoming increasingly taller. This is why there is an increasing need for more electricity. This also puts more pressure on the pumps and the entire electricity system of the building. This is where one feels the need of water pumps distributors who deal in energy-efficient products.

Dealing with frugal budgets 

In most cases, these residential complexes have frugal budgets for maintenance. Any extra load placed on their electricity usage can only make things worse for them in this regard. This is the reason why they must think of service providers such as Kirloskar pumps dealers. They are the ones that would be able to offer them the energy-efficient products that they are looking for. This way they would be able to save quite a lot of money on their electricity bills.

The contribution of pumps to electricity bills in a society

If you wish to find out how much these pumps are contributing to the electricity bills of your society all you need to do is do some calculations and audits. In most cases, 50 per cent of your electricity costs each month are contributed to by these pumps. This is the reason why you need to get in touch with the water pumps distributors in Navi Mumbai and get energy-efficient products from them. 

Where does the money go? 

In most buildings, there are three major heads where the expenses happen – lights, pump, and elevator. Out of these lights consume the least amount of energy and pumps take up the most. This is the reason why you should first look at the pump if you are serious about reducing your energy bills and, more importantly, your energy consumption. This is why you need water pumps distributors in Thane who can provide you with energy-efficient products and help you save money. 


In the case of appliances, efficiency is basically the rate at which it is able to convert electricity into some form of energy.All pumps are designed in such a way that they are able to handle a certain amount of load where it has maximum efficiency. This particular juncture is also known as BEP (Best Efficiency Point). In most cases, it has been seen that when operated at their BEPs the small pumps have an efficiency rate of around 50 to 70 per cent. You need to keep in mind that you have to buy your pumps from pump manufacturers in Mumbai who are known to offer energy-efficient products.
