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

The latter has gained traction through the years, changing into one of many extra in style panel sizes for residential photo voltaic purposes.

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

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

On this article, we enable you decide whether or not these panels are the fitting selection for you.

What are 72-cell photo voltaic panels?

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

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

What are photo voltaic cells?

Should you look carefully at a photo voltaic panel, you’ll discover it accommodates a number of particular person square-shaped parts. These square-shaped parts are referred to as photo voltaic cells.

A photo voltaic cell is a element accountable 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 may well produce, different key elements, reminiscent of cell effectivity, play a fair larger function.

Though there are at the moment 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 huge).

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.

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

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

Evaluating photo voltaic panels: variety of photo voltaic cells

On account of their smaller measurement, 60-cell panels are a extra widespread selection for residential purposes or in RVs and campervans. The ability output of those panels ranges from 150W to 300W.

Subsequently, a 72-cell photo voltaic panel might fit your state of affairs higher when you’ve got the area and require extra energy. For reference, a 72-cell photo voltaic panel’s wattage normally ranges between 300W and 450W.

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

On account of its massive measurement and heavy weight, a 96-cell photo voltaic panel shouldn’t be a sensible choice for residential purposes. Nonetheless, it’s extremely efficient for industrial purposes like photo voltaic farms.

What about voltage and wattage?

Every customary 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:

Complete 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 also referred to 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 scale 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 value being $490.

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

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

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

Professionals and cons of 72-cell photo voltaic panels

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

Professionals

• Able to producing extra electrical energy than customary 60-cell panels with the identical effectivity ranges.
• Nice for bigger properties or companies.
• Require fewer panels than 60-cell modules to realize 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

• Normally dearer than 60-cells photo voltaic panels.
• Require more room for set up
• Transport and set up may be troublesome because of their heavy weight.
• Not really helpful for off-grid installations reminiscent of 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 definitely worth the funding?

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

When you’ve got sufficient area and want a system that may generate a considerable amount of power, then 72-cell photo voltaic panels will make for a very good funding.

Nonetheless, a smaller panel — reminiscent of a 60-cell variant — could also be a greater choice for those who’re pressed for area and don’t require as a lot energy. This is applicable to off-grid techniques (RVs, campervans, and so on.) and smaller homes.

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

So do your analysis and contemplate all of your choices earlier than making a call.

Are photo voltaic panels with extra cells superior?

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

Nonetheless, different, extra vital elements play a task, reminiscent of:

• Cell measurement
• Cell kind
• Effectivity
• Price 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 value extra.

Nonetheless, for large-scale/industrial purposes, panels with greater than 72 cells are normally a greater choice, as fewer modules are required to realize 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 it’s essential generate a considerable amount of power and have sufficient area for set up, a 72-cell photo voltaic panel is usually a nice selection.

Nonetheless, for those who’re on a decent funds and/or your power demand shouldn’t be that prime, a smaller and cheaper panel could also be a greater choice.

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