PV Solar Efficiency?

As with everything else in our technology-driven world, huge advances in the sphere of PV (Photovoltaic) technology has increased the conversion efficiency of PV solar panels by leaps and bounds, which leaves us with the question; PV solar efficiency?

We obviously want PV solar to be efficient, since it’s one of the greatest hopes for most South Africans, living with a beleaguered electricity grid, to be free from its consistently unstable performance and endless rounds of load shedding, for which there is seldom any warning.

Add to this the exorbitant cost of merely heating water, keeping appliances running and keeping the lights on and we’ve about hit ground zero when it comes to deciding to cut ties with Eskom, at least as much as our budgets will allow!

PV solar efficiency?

Considering that buying a PV solar system isn’t cheap, we naturally want to know that finding the funds to make the investment will be worth it, which goes to the question of the efficiency of PV solar.

Bottom line, PV solar panel efficiency is based on the amount of sunlight that shines onto the panel and is then converted into electricity, a conversion efficiency that has reached an average of pretty well over 20%, according to most experts.

What this means, in essence, is that the power rating considered of a standard size PV solar panel has increased from what used to be 250W, to 370W and more today.

PV solar panel efficiency factors to take into account

There are two main factors to take into account when determining the efficiency of PV solar, which are:

Photovoltaic (PV) cell efficiency

The type of silicone used and design of the individual photovoltaic cell contributes to its efficiency, such as whether either a P-type or N-type of silicone is used. The cell efficiency is also determined by the type of substrate used and the actual photovoltaic cell structure, with its efficiency calculated by a very technical term called the fill factor (FF), which gives you what will be the maximum conversion rate of sunlight to electricity.

This is all about calculating the optimum operating voltage and current that can be expected of the cell itself.

PV solar panel efficiency

The efficiency of a complete PV solar panel is determined by the layout and configuration of the photovoltaic cells, as well as by the size of the panel itself.

There is a lot more attached to understanding PV solar efficiency, but the best way to get to grips with questions as complicated as these would be to chat to the solar experts at Renaissance Solar.

This is their bailiwick, and the passion that drives their commitment to excellence and quality solar products, will assure you of a clear understanding of the principles behind PV solar efficiency, before you even get to designing the ideal PV solar system for your home or business.

PV Solar Definition?

Before we get into definitions, let’s look at a bit of inspiration when it comes to considering PV solar as an alternative energy source, compared to that of the expensive and unstable grid we’ve been forced to come to terms with in South Africa.

What you need in terms of getting the highest efficiency out of PV solar panels is at least 4 hours of peak sunlight, and nothing is easier to achieve than that in our beautiful country, where we average between 4.1 and 6.3 peak sun hours a day!

Of course, you’ll have a little more or a little less depending on where you’re situated in the country, but, nothing takes away from the fact that South Africa’s resources for solar energy is one of the highest in the world.

Nothing is perfect, and yes, your PV solar panels will produce less energy on cloudy days than on sunny, however, based on the reality of the figures above, you’ll have a reliable source of free electricity throughout the year, based purely on the energy of the sun!

By the way, Europe is way ahead of us in terms of reliance on solar energy, yet they experience, in comparison to our annual solar radiation average of 220 W/m2, only 100 W/m2!

Still want the PV solar definition? Well, let’s see how simplified we can get in our approach to this question, so that we leave the real nitty-gritty to the experts at Renaissance Solar!

PV Solar definition?

The term PV stands for photovoltaic, which is a fancy word for what happens when sunlight (photo = light) is converted into electricity (volt). 

A single PV cell is very small, and on its own would only be able to produce a measly 1 or 2 watts of power, however, when many of these single PV cells are connected together in strings or chains, they then become the solar panels we see on the roofs of homes and businesses.

This connecting of strings or chains of the PV cells is what is designed to boost the power output of the PV solar panel.

These Photovoltaic cells are constructed of a variety of very thin semiconductor materials, with silicone being the most commonly used type of material.

On their own, these cells would never be able to withstand all that mother nature has to throw at them year in and year out, especially when you consider that a quality PV solar panel has a lifespan of upwards of 25 years, which is why they are kept safe in a sandwich of either glass or plastic, or a combination of both.

Once you’ve installed more than one PV solar panel, you’ll have the beginnings of a PV solar panel array, and depending on what you want out of your PV solar system, the more you have, the more solar energy you’ll be able to rely on.

In terms of designing a PV solar system that can meet with any level of electricity requirement, whether large or small, the sky is the limit, but, PV solar panels are simply one part of what will form a complete PV solar system.

PV Solar Cost?

Although attitudes are fast changing towards investing in PV solar systems, in light of ever-increasing electricity tariffs, the knee-jerk response for many, at first, is to ask the question; PV solar cost?

This is totally understandable in an economy that has the average South African tightening belts to a constricting level, leaving little room for saving, and the cutting down on many things that are now considered a luxury.

For instance, a holiday or even a weekend away has become more of a luxury than ever before for many, but that’s something we can all find a way to come to terms with and find ways around, if we have to.

What we can’t come to terms with or find ways around is our reliance on electricity, which at current prices and predicted escalations is on the fast track towards becoming a luxury, no longer a basic human right.

In South Africa we have been forced to live with and accept regular rounds of load shedding and the attendant losses that ultimately affect all of us, whether as a result of having food spoil in freezers, or paying an even higher price at the supermarket due to the increased cost of keeping the power on.

There is only one way to change this scenario and begin to live with a source of energy we can rely on, and that’s to set aside preconceived ideas about the cost of PV solar systems and start looking at the facts.

PV in Solar Meaning?

Want to get a grip on the basics of PV in solar meaning? This is generally where most of us go when we get to the point of seriously considering a move to solar energy, and begin facing some of the most common terminology attached to taking that first step.

With two major types of solar technology dominating the scene, mainly that of photovoltaic (PV) and of solar thermal technology, it is mainly photovoltaic solar technology that makes up what you see on rooftops today, powering both homes and businesses.

PV in solar meaning

At its most basic, solar photovoltaic is a perfectly designed technology that allows for electricity to be produced directly from the sun, without the use of any moving parts.

The origin of the term photovoltaics is from the Greek word ‘phōs’, which means light, and the word volt, named by physicist Alessandro Volta, who invented the first electric battery in the mid-1700’s.

We’ve come a long way since then, no doubt, and with the advent of photovoltaic solar technology, the world of energy production from the sun has catapulted mankind into choosing solar energy as the best source of free energy available today.

The makeup of a PV solar panel

Single Photovoltaic cells are very small and on their own wouldn’t be much use, however, when these small cells are connected (or strung) together, they become the very efficient PV solar panels we see on rooftops today.

PV cells are most commonly made of silicone because of its semiconducting properties, and when the sun shines directly on these cells in the solar panel, an electric field is created, from which you’re able to receive a reliable, stable source of electricity for your home.

Although a strong sun is the ideal in terms of getting the most out of PV solar panels, they are still able to produce sufficient electricity even in cloudy weather.

Technically speaking, strings of the small solar cells are created under glass in order to form photovoltaic modules, which is simply what a PV solar panel is in its complete form.

Mounted on existing rooftops, these PV solar panels are designed to last up to and beyond 25 to 30 years, making them one of the best investments in terms of assuring yourself of a guaranteed, phenomenal ROI.

Maintenance-free PV solar panels

If you’re ready to seriously consider investing in a PV solar system, then it’s time to speak to the passionate experts at Renaissance Solar in Cape Town.

With local professionals like this on your side, you can count on quality PV solar panels that will not require any maintenance, other than giving them a clean every now and then, which is seldom necessary in a high rainfall area like Cape Town.
