Are you interested in taking your home as much off the grid as possible but can’t seem to calculate how many solar panels you will need? The team at Rennaissance Solar can assist. We know all there is to know about solar power. 

 

Perhaps one of the most challenging aspects of calculating the number of solar panels is estimating your household’s annual energy usage. Various consumer products that are on the larger side can change your requirements significantly. For example, if you are heating a swimming pool or have an air conditioning system, the size of your solar solution will change drastically.

Calculating Your Solar Panel Requirements

If you’re wondering how to estimate energy consumption numbers and how many solar panels you’ll need, here’s the breakdown. Start by looking at how many kWh (kilowatt-hours) of electricity you use annually. Your service provider can provide you with a summary of your total power consumption over the last 12 months. 

 

One kWh is equal to 1000 watts per hour. If you have 20 lights in your home that use 50-watt bulbs, you’ll use one kWh of electricity by having every light switched on for one hour. The average household uses around 10 000 to 11 000 kWh per year.

 

Look at your monthly electricity bills and see what you are spending per month and/or the units consumed. If it is around R1500 – R2 000 per month then a 5kVa Hybrid system will suit you with 8 x 455W panels and 1 x 5.5kWh Lithium Ion battery. If it is around R2 500 per month you need more like 10 panels and 2 batteries.

 

When you get to R3 500 per month you need an 8kVa inverter, 14 panels and 2 or 3 batteries.

And if around R4 000 a month then it’s 10kVa of the inverter, 16 Panels and 2 – 3 batteries. And so on …

 

How Many kWh Can Solar Panels Generate?

The amount of kWh solar panels can generate will depend on their exposure to sunlight. This will vary according to where you are in South Africa as well as what time of year it is. 

 

While it’s possible to add more solar panels after the initial installation, the best option is to accurately size your system based on your prospective energy consumption. If you plan to invest in an air conditioning system, it must be taken into account. 

 

If you’re a homeowner in the early stages of solar shopping and you would just like a ballpark estimate for an installation, we suggest you book a consultation with the team at Renaissance Solar. Give us a call today!

 

Power output is an essential metric for your residential or commercial solar panel system. During the purchase and installation of your solar energy system, the price is calculated on the complete power output of the solar panels and displayed in watts or kilowatts.  ( many other factors determine price too: size of inverter, number of batteries)

 

Three vital factors control the amount of electricity produced by solar panels: Panel size, solar cell efficiency and the amount of sunlight the panel receives.

Panel Size

The term “solar panel” indicates the traditional silicon PV panel typically used for residential applications. Each solar panel contains little squares that are individual solar cells. Linked by wires, these cells are where the magic happens, and electricity is made. The more solar cells work together, the more power they create. If you’re trying to calculate how much electricity your panel will create, the size matters.

 

While the standard size of solar panels remains the same, modern panels generate more electricity. Mainly due to improvements in cell efficiency by the manufacturers. 

Solar Cell Efficiency

In the mid-1900s, the first solar cells could use 6% of the sun’s energy to convert into electricity. These days, the efficiency is closer to 25% in more advanced solar cells, with an average efficiency of around 19% for residential use. By combining the size of the panel with the efficiency of the cells, you get the power rating.

Power Rating

Panels come in many different wattage ratings, but the most advanced solar panel produces nearly 320 watts of power.  (dont know where you get this from) These types of panels tend to be more expensive but work well if you only have limited space on your roof. Your solar installation team will assist you in determining exactly how many panels you would need to produce sufficient energy for your home. 

How Many kW Solar Do I Need?

 

Depending on where you are in South Africa and what time of year it is, solar panels will generate a different amount of power. Adding more solar panels to your system is possible after installation, but you should size your system accurately based on your anticipated energy consumption.

Best quality PV solar panels?

Before we get into what you can expect in terms of quality and longevity from Renaissance Solar PV panels, let’s take a peek into how this team has simplified what solar electricity power is.

In their own words, “Solar PV systems generate electricity by converting sunlight directly into electricity. The Photovoltaic cell (PV) consists of one or two layers of a semi conducting material, usually silicon which – when light shine on it – creates an electric field across layers, causing electricity to flow.”

Simplicity at its best! This writer is yet to find an explanation that sets out what solar electricity power is, that is this succinct and understandable to those of us who aren’t solar fundi’s!

The advancement of solar technology has been an ongoing race that started well over a century or more ago, and there are still incredible advancements happening as we speak, in our super-fast technological age.

Sometimes the history of something as revolutionary as solar energy and its birth leads us to questions like; who invented the solar cell? There’s seldom one person that can take credit for these types of advancements and inventions though.

More often than not, one inventor begins with one step, then another takes it a step further and so on, until, as we see today, we find relief financially, as well as from load shedding in South Africa, by what these searching and inventive minds started so very long ago.

Today we can rely on PV solar systems to keep us going while the rest of the country is in darkness, and we get to take a major financial load off when it comes to electricity tariffs, as they increase exponentially each year.

Who invented the solar cell?

When the historical inventors of the solar cell, known today as a photovoltaic cell (PV) or, in terms of a full system, a solar PV system, they weren’t thinking, as we do today, about protecting the environment.

They hadn’t yet seen what man would do to destroy our natural resources, which would send us in search of alternative energy sources. It was about pure science, and enquiring minds that gave us the opportunity to care about what the future holds for the environment today.

Here’s a very brief look at each genius that started the ball rolling towards the solar cell, though each deserves so much more, however, space is limited;

Edmond Becquerel

In 1839 Edmond Becquerel discovered the photovoltaic effect. This young French scientist discovered the process that can produce an electric current when exposed to light.

Augustin Mouchot

During the 1860’s Augustin Mouchot, inspired by Edmond’s work, started registering solar powered engine patents, which further inspired physicists right across to America. From there, this mathematician filed further patents in 1888 for solar powered devices. Phenomenal!

Edward Weston – the real father of solar cells!

Not too long after this, Edward Weston became the father-inventor who received 2 patents for solar cells; and so the journey began. In Weston’s words, he proposed to “transform radiant energy derived from the sun into electrical energy, or through electrical energy into mechanical energy”.

All these men with minds that let their imagination and hunger for advancement, along with their extensive knowledge, deserve so much more than what is written here, however, people such as the team at Renaissance Solar carry on their dreams today, with the same passion and commitment to a future that relies on the sun for energy, and nothing less.

Down to earth, honest and straightforward, Renaissance Solar is more than willing to share their expert knowledge with anyone who would like to know more about transitioning to solar energy, no matter where you start, big or small! 

 

Well, let’s get right into it with the question on the tip of many tongues right now; is it worth getting solar PV? The short answer? Yes, but we won’t leave you hanging there when it comes to something as important to your future and finances as a solar PV system can be.

We live in a world that has placed us all in a state of uncertainty, and we live in a country where load shedding adds an extra weight to that uncertainty, never knowing when the simplest of life’s tasks will become a major challenge, just because of a sudden power outage.

Homeowners and business owners are at wits end; solar power or noisy generator, just to survive and keep going, so that nothing is lost at whatever stage Eskom chooses as its next unpredictable load shedding schedule.

This has been going on for well over ten years now, so, let’s ask the question again at this junction!

Is it worth getting solar PV?

In a beautiful country that has abundant sunshine, to the extent that South Africa is the perfect site for solar, with a phenomenal 2,500 sun hours a year, compared the 1,000 hours of most European countries, the real question should be; why doesn’t every roof have solar panels soaking it up, turning it into electricity?

Aside from load shedding, lets whisper here about the ever-increasing electricity tariffs that have all but turned electricity into a luxury even for the average South African household, and it isn’t going to get any better in 2023!

Even if all you do is start with the smallest solar PV system from Renaissance Solar in Cape Town, South Africa, you’ll already start knocking a major chunk off your electricity bill every year, with quick payback periods that offer a great ROI.

No matter how small you start, you can always add on, and Renaissance Solar will be around for a long time to come, just as stable as they have been over the last decade and more.

The benefits of a solar PV system far outweigh any disadvantages, by a long shot. At most, your system won’t operate as well on a cloudy day as it would on a sunny day, but with the right batteries and inverter, and the right system to meet your power requirements, you won’t feel load shedding at all.

Let’s face it, the less you have to rely on an unpredictable grid that costs more every time you open your eyes, the better life becomes. 

An added bonus, is that according to local real estate agents, more than 50% of those in the market for buying homes, are willing to pay anywhere up to R 100 000.00 or more, for any property that offers a reduction in electricity costs. Solar PV system anyone?
