Different types of Solar PV Panels. Roof Mounted vs Ground Mounted

A revolutionary discovery when it comes to renewable energy, solar panels are expected to replace fossil fuels across the globe, if used mindfully and employed innovatively. As we know, a single solar PV cell generates only 0.1 watts to 2 watts of energy. For its application in practical ways, such cells are connected to make a solar PV module in order to provide the required standard output voltage and power.

And while it is important to pick the right solar panel as per your needs, what matters is which mounting system will work best for your living space, fit into your budget, and energy needs.

The two types of solar mounting systems: Roof mount vs. Ground mount 

While the roof mount systems are fixed to the brackets on your roof, a foundation is built at ground level for ground mount systems.

Roof solar mounts 

The advantages of going for a roof mount system are rather few. Like it is less expensive, easier to install as well as utilizes less space. But the list of its cons is too long- 

Cons:

  • Accessing the panel would be a hassle
  • The higher panel temperature results in lower panel output
  • Planning to replace your roof? Get ready to install the system again!
  • As there is constricted space on roofs, the size of the system has to be restricted

Ground Solar mounts

The requirement of intensive labor, expensive installation and permitting process, and not exactly an aesthetic addition to the space around your house.

But despite its cons, Ground mounts are the best option for you

They are easier to access, clean, and repair, if need be. Not only does it have a stronger racking, but its size also is not decided on how big the roof is and are producing higher energy inputs because of the cooler temperatures. Want to get your roof replaced? Go on, your panels are not in need of reinstallation!

Necessary Things To Know While Purchasing Water Pump Spare Parts

You cannot limit the uses of the water pumps within the industry itself. Its uses are found common in almost all areas like households, hospitals, schools, colleges, workplaces, etc. The water pump comes in handy for many reasons. For instance, you may live in an area where flooding occurs very frequently. You will need a submersible pump there to help clean up afterwards. In case if you live in a lavish villa, you will need a pump to fill your swimming pool with water. You may need it every day to pump out water from the borehole or water well. 

Whatever the need may be, you must know certain necessary things while purchasing water pump spare parts from water pump distributors in Navi Mumbai

The following are some of them:

GPM discharge capacity: All types of water pumps are measured in GPM discharge capacity which tells you how quickly, efficiently and powerfully the water is pumped out. To be precise, the GPM discharge capacity is defined as the rate at which the water flows from the source to the discharge point in gallons per minute. If the pump is intended for industrial purposes, you have to choose the one with a higher GPM discharge capacity.

Vertical suction lift: The vertical suction lift will tell you what the vertical distance is from the water source to the water pump. This will be useful when you are using the water pump for draining a pond or a flooded basement. With the help of a vertical suction lift, you will be able to know the distance to get it to the pump for the discharge of water.

Maximum head lifts: The maximum head lift is used to know what the total height of the pump is from the water source to the discharge point. This will also tell you how powerful the pump is and what distance it can move water over for the job that you need the pump for. 

Type of water pump: There are different types of water pumps, depending on the purpose, you can choose the best water pumps from Kirloskar water pumps Navi Mumbai. The different types of water pumps available with them are the following:

  • Submersible pumps
  • Water-boosting pumps
  • Self-priming pumps
  • Borehole pumps

The different types cannot be limited within the above list. Make sure that you research the different types of pumps and get the desired one for the intended purpose.

Liquid or Slurry? Which Pump should you use?

If you’re looking to install a pump, your first consideration should be its purpose. What do you need your pump to do?

We can break this down into:

  • What type of medium do you need to transport or process?
  • How far do you need to move it?
  • What volume and at what flow rate will be required?
  • What power source do you have available? – electricity, compressed air etc.

In this post we’re going to focus on the first point. By understanding the type of material, whether solid or liquid or viscous, you will be able to identify the type of pump you need.

Flowable Liquids vs Slurry Mediums

Anything that needs to be pumped has a viscosity. For instance, water is 1 cPs while a much thicker liquid like a fruit pulp can be about 5,000 cPs. If it’s a slurry from a mine, this also is viscous to some degree. Slurry will also have a solids percentage which has to be taken into account. A general rule of thumb is, ‘if you can pour it, you can pump it’. There is a list of typical viscosities here.

Pumps for Different Mediums

Your first step should be to understand the nature of the product you are wanting to process or transport via a pump. If the medium pours easily without chunks of solid material present, then we can happily describe this as a liquid. But the real test is how viscous the liquid is. Likewise, if there are solids present, then this medium will require different equipment. There is a stark difference between pumping water which is thin and extremely fluid as opposed to oil or grease which is thick, or an abrasive medium which contains solids.

Let’s take a look at three common mediums and the pumps you might need:

  • Water: This is the simplest medium to transport. It’s easy to move around because it has low viscosity. Therefore either a centrifugal style pump, which includes submersible pumps, or even a pneumatic pump for dewatering, will suit your needs.
  • Oil: Now things get trickier. When a medium becomes oily, it’s still a liquid, but because it has higher viscosity you’re going to need a different style of pump. It needs to be able to withstand increased friction. Something like a gear or lobe pump which can handle higher viscosities. However, these pumps cannot run dry, so if your system needs a pump that may run dry at some point, you’ll need a tube or diaphragm pump.
  • Slurries and Abrasives: These mediums have deposits within them which are solid. Pieces of rock, metal, or other minerals etc. There are two considerations here. The first is to make sure that your pump is powerful enough to transport such medium, the second is to ensure that the pump is durable enough to withstand the abrasive nature of the medium. A peristaltic hose pump or a heavy duty slurry pump is ideal for such a situation.

Other Considerations

In some instances the medium you are using might be corrosive, so in this case you’ll need to choose a chemical pump which can process what you need while keeping an environment safe from contamination.

Ways to preserve or increase the efficiency of a centrifugal Pumps

Centrifugal pumps are capable of providing efficiencies up to 93 percent and even the smallest pumps have an efficiency that falls into the 50 to 70 percent range. Centrifugal water pumps convert mechanical energy into hydraulic energy (flow, velocity and pressure), while a centrifugal motor i.e., AC motor converts electrical energy into mechanical energy. 

Countless nitty-gritty details and factors are carefully monitored to ensure that the efficiency of centrifugal pumps is maintained and increased if possible. Let’s take a look at the methods followed to up the efficiency of the pumps:  

  • By employing high specific speed

As pump’s efficiency is directly dependent on the specific speed, the higher the latter is the better the efficiency is, resulting in energy conservation

  • Using good wear ring with proper clearance

Though even a well-designed pump comes with a diametral clearance of 0.2 to 0.4%, as long as it remains between 0.6 to 0.8 % there is no issue. But the moment it starts increasing beyond this limit, the efficiency of the pump drops. As pumps continuously wear with time, the best option here is to continuously switch the wear ring, having good quality. 

  • Avoid running one pump instead of two

It is often seen in many installations that two pumps are operating simultaneously even when the required supply can be managed by a single pump. This not only leads to wastage of energy but also limits the pumps to work at their full efficiency. 

  • Maintaining good insulation and ensuring that there is steam tracing in the suction line of the pump

An often neglected yet necessary arrangement, insulation and steam tracing help in diminishing the damage done by a liquid’s viscosity which causes fluid friction and disc friction. The higher the viscosity of the liquid, the lesser is the pump’s efficiency

  • Selecting a pump ideal for its application

Every pump generates different amounts of flow at different pressures, so often it happens that a pump, improper for its application, is chosen. It’s either too large or too small and ends up reducing the system performance as it results in inadequate flow.

Fundamentals of Hydro Pneumatic Pumps

When it comes to the usage of Hydropneumatic Systems, innovatively crafted water pumps, its high power design is mostly applicable in situations where water is needed in variable amount but has to be delivered continuously and with uniform pressure- like to all floors of high rise apartments and commercial buildings. Such places usually comprise of bathroom fittings like shower, Jacuzzis, that need pressurized water to ensure that the accessories work properly.    

The types of Hydropneumatic systems:

1. Constant Speed System– Fx1- This HYPN system is used primarily in residential houses and buildings as well as small scale commercial set ups where is is employed in transferring water and filling tanks.

2. Cascade system-MX- In this, all pumps work via one VFD (a variable-frequency drive). It is mostly used in industrial applications in medium size commercials and residential buildings.

3. All pumps VFD system-EX- These are majorly used by large commercial sectors like hospitals, malls, airports, metros, based on what is the need of the specific sector.

The formation of a Hydropneumatic system:

It consists of 2 to 6 multistage centrifugal pumps, which are capable of bearing high pressure. It also has high-resistance valves and a control panel to control the number of pumps that will be functioning based on system discharge and the rate of pressure. As the centrifugal motors and pumps are prone to start and stop many times, pressure tanks are there to reduce the frequency. It also consists of switches build to sense high and low pressure as well as a pressure transmitter.

Made up of rubber bladder, the pressure tanks are surrounded by pressurized air as water is a non-compressible fluid. As soon as you open a tap, the pressure in the tank is reduced as the water level goes down. As soon as the pressure level drops to a certain level, the pressure switch senses it and turns on the pumps and turns it off when the desired level of pressure is achieved.
