Do you have to purchase 72-cell photo voltaic panels?









Photo voltaic panels are available in numerous configurations — from smaller, 36-cell thin-film photo voltaic panels to bigger 72-cell monocrystalline choices.

The latter has gained traction over time, changing into one of many extra well-liked panel sizes for residential photo voltaic functions.

As a home-owner trying to spend money on photo voltaic, having quite a few choices at your fingertips is improbable. Nevertheless, it could additionally muddy the waters and make the funding course of tougher.

So, are 72-cell photo voltaic panels well worth the funding?

What are 72-cell photo voltaic panels?

Because the title implies, a 72-cell photo voltaic panel is just a photo voltaic panel comprised of 72 particular person power conversion parts.

Let’s take a better have a look at the function and make-up of those cells.

What are photo voltaic cells?

For those who look intently at a photo voltaic panel, you’ll discover it incorporates a number of particular person square-shaped parts. These square-shaped parts are known as photo voltaic cells.

A photo voltaic cell is a element chargeable for absorbing daylight and changing it into power.

Whereas the variety of photo voltaic cells in a panel can affect the quantity of power it could produce, different key elements, corresponding to cell effectivity, play a fair larger function.

Though there are at present many various photo voltaic cell sizes, the usual measurement of a photo voltaic cell is 156 mm by 156 mm (roughly 6 inches lengthy by 6 inches extensive).

Different solar cell sizes.
The scale of a normal photo voltaic cell measurement is 156 mm x 156 mm (6 inches). Nevertheless, there are at present a number of different photo voltaic cell sizes, most of that are bigger than the usual cell, to generate a larger amperage.

The typical measurement of a 72-Cell photo voltaic panel

A 72-cell photo voltaic panel is organized in a 6 x 12-cell grid configuration, whereas the extra widespread 60-cell photo voltaic panel follows a 6 x 10-cell design.

Understanding the grid configuration of a 72-cell photo voltaic panel and the 

dimensions of a normal photo voltaic cell, we are able to decide the typical sizes of a 72-cell photo voltaic panel: roughly 39 in extensive x 77 in lengthy (99 cm extensive and 195 cm lengthy).

The configuration of a 60, 72 and 90-cell solar panel.

Evaluating photo voltaic panels: variety of photo voltaic cells

As a consequence of their smaller measurement, 60-cell panels are a extra widespread selection for residential functions or in RVs and campervans. The facility output of those panels ranges from 150W to 300W.

Subsequently, a 72-cell photo voltaic panel might fit your scenario higher you probably have the house and require extra energy. For reference, a 72-cell photo voltaic panel’s wattage often ranges between 300W and 450W.

As for 96-cell photo voltaic panels, they’re much bigger, so they have an inclination to generate a larger quantity of energy (between 400W to 500W of energy).

As a consequence of its massive measurement and heavy weight, a 96-cell photo voltaic panel just isn’t a sensible possibility for residential functions. Nevertheless, it’s extremely efficient for business functions like photo voltaic farms.

Variety of Cells in Photo voltaic Panel Wattage Vary Common Dimensions
60 cells 200W to 300W 65″ lengthy and 39″ extensive
72 cells 300W to 450W 77″ lengthy and 39″ extensive
96 cells 400W to 550W 77″ lengthy and 50″ extensive

What about voltage and wattage?

Every commonplace photo voltaic cell produces round 0.5 volts. When linked in sequence, the panel’s complete voltage equals the sum of every cell’s voltage. 

Subsequently, the open circuit voltage of a 72-cell photo voltaic panel is 36V:

Whole Voltage (V) = 72 cells x 0.5 V = 36 V

Following the identical logic, a 60-cell photo voltaic panel can produce as much as 30 volts (open circuit voltage), so its nominal voltage is inadequate to cost a 24V battery effectively.

Conversely, 72-cell photo voltaic panels are often known as “24V nominal photo voltaic panels” since their voltage is right for charging a 24V battery or two 12V batteries wired in sequence.

As for the amperage, it’s immediately proportional to the measurement of the photo voltaic cells  that’s, the realm of the semiconductor. Subsequently, bigger photo voltaic cells have a tendency to provide extra amps than standard-sized cells.

In abstract, the wattage of a photo voltaic panel is immediately proportional to the variety of photo voltaic cells (determines voltage) and the size of the photo voltaic cells (determines amperage).


How a lot does a 72-Cell photo voltaic panel price?

Our analysis has proven that costs can vary between $380 and $600, with the typical worth being $490.

That stated, the price of a 72-cell photo voltaic panel can fluctuate considerably and depends upon elements corresponding to:

  • Set up price
  • Producer/model
  • Expertise (monocrystalline, polycrystalline, thin-film)
  • Wattage

Relying on the dimensions of your photo voltaic array, prices can add up rapidly, so make certain to issue them into your finances when deciding whether or not or to not spend money on 72-cell photo voltaic panels.


Execs and cons of 72-cell photo voltaic panels

As with all issues in life, 72-cell photo voltaic panels include their execs and cons.

Execs

  • Able to producing extra electrical energy than commonplace 60-cell panels with the identical effectivity ranges.
  • Nice for bigger properties or companies.
  • Require fewer panels than 60-cell modules to attain the identical power output.
  • Often, the value per watt may be lower than 60-cell photo voltaic panels.
  • Cheaper to put in on a big scale.

Cons

  • Often dearer than 60-cells photo voltaic panels.
  • Require more room for set up
  • Transport and set up may be troublesome resulting from their heavy weight.
  • Not really useful for off-grid installations corresponding to RVs and campervans.
  • Their cumbersome nature could make them troublesome to maneuver on a roof.
  • Not environment friendly for small-scale techniques.

Are 72-cell photo voltaic panels well worth the funding?

Whether or not 72-cell photo voltaic panels are worthy investments depends upon your particular person wants and finances.

When you have sufficient house and wish a system that may generate a considerable amount of power, then 72-cell photo voltaic panels will make for a great funding.

Nevertheless, a smaller panel — corresponding to a 60-cell variant — could also be a greater possibility for those who’re pressed for house and don’t require as a lot energy. This is applicable to off-grid techniques (RVs, campervans, and so forth.) and smaller homes.

It’s additionally price remembering that different photo voltaic panels, corresponding to half-cut cell photo voltaic panels, could also be higher suited to your wants.

So do your analysis and think about all of your choices earlier than making a choice.


Are photo voltaic panels with extra cells superior?

Usually talking, photo voltaic panels with extra cells are extra environment friendly and might generate extra electrical energy than these with fewer cells.

Nevertheless, different, extra important elements play a task, corresponding to:

  • Cell measurement
  • Cell sort
  • Effectivity
  • Value per watt

Finally, photo voltaic panels with greater than 72 cells aren’t viable for residential use: they’re too massive and too heavy for roof set up and price extra.

Nevertheless, for large-scale/business functions, panels with greater than 72 cells are often a greater possibility, as fewer modules are required to attain the specified output.

Subsequently, the general price of constructing bigger photo voltaic arrays may be considerably smaller utilizing photo voltaic panels with extra cells.


Remaining ideas

If that you must generate a considerable amount of power and have sufficient house for set up, a 72-cell photo voltaic panel could be a nice selection.

Nevertheless, for those who’re on a decent finances and/or your power demand just isn’t that prime, a smaller and cheaper panel could also be a greater possibility.

We hope this text has helped you make an knowledgeable determination as as to if 72-cell photo voltaic panels are the fitting selection for you.
