How Much Electricity Does a Solar Panel Produce

How Much Electricity Does a Solar Panel Produce?

The amount of electricity a solar panel produces depends on three things:

  • Size of the panel
  • The efficiency of the solar cells inside
  • Amount of Sunlight the panel gets

What is a Solar Panel?

A solar panel is a photovoltaic panel designed to absorb the sun ray to produce electricity or heating. The typical solar panel is about five and a half feet tall and 3 feet wide.

Each solar panel has approximately sixty little squares. These squares are individual solar cells, which are linked together by wires.

Inside each individual solar cell is where the electricity is made; electricity is then carried by the wires to a junction box where the panel is hooked into a larger array. The amount of power a solar panel makes is based on the wattage of the solar panel.

The residential solar panels available in 2018 contain 60 solar cells joined together to produce around 260-300 watts, or they could have 72 cells joined together to produce between 360-400 watts.

The higher the wattage of a solar panel the more electricity it produces because it has access to more solar irradiation.

The amount of electricity solar panels produce also depends on average sunlight over the course of a year. To know this you need to find your place on the globe to see if your area is more cloudy, and therefore less available energy from the sun to convert into electricity.

Malaysia, for example, is a great place to produce solar energy. That is why the solar industry in Malaysia is expanding with several solar power companies and solar farms.

In Malaysia by February 29, 2018 the solar power capacity was at 140MW out of a total of 311.6MW, and the number of applications for solar as a source of power was 348 out of 377 applications under the Fit according to SEDA. This could give you an idea of how big the industry is in Malaysia.

How many solar panels are needed to power an average house?

The average house uses about 900 kWh per month. This is a lot and you can really save a big amount of money by using solar power.

So how do you calculate how many solar panels you need? Let’s take 900 kWh and divide by the amount of kWH one solar panel produces, that is around 30 kWh monthly. You will need 30 panels to produce 250 watts per panel to produce 7,500 kW.

Of course, before you install your solar panels, it’s recommended to consult a solar company. The expert will tell you how your solar power system should be depending on how much devices you use and your lifestyle, for example:

  • Light Bulb uses 60 watts
  • Laptops use 45 watts
  • Desktops between 150-300 watts
  • Window air conditioning range between 500 and 1500 watts
  • Central air conditioning can use 3500 watts.

All those devices add up with variations. Most of your electricity usage probably happens at night, but if you work at home this could change. Your solar installer will talk to you about all of the options.

How to Store Energy

Solar panels only generate power as the sun shines. This mean you will need a way to store the energy. One solution is to use a battery, but the majority of people prefer to stay connected to the grid. This option is easier and cheaper.

If your solar panels are producing more power than you are using, the excess power will go back into the grid. You can pull energy from the grid at night, or anytime you need extra power.

If you use a grid-connected system, you don’t have to worry if you need more power than your solar system provides. Make sure you talk to your solar installer about all the options, and which one is best for you and your home.

The Changing Tide of Solar Energy

Renewable energy became the buzzword of the 21st Century as more and more nations saw the urgency to combat pollution and global warming. Of all renewables, solar energy becomes one of the growing trends as tech company giants like Apple and Google, automobile companies like Tesla, Nissan and Bentley all heavily invested in solar energy.

With China being the largest installer of solar photovoltaics (PV), solar energy is seen to be better energy source as is both practical and more cost-effective than fossil fuels for both the commercial and residential. In Malaysia alone, more and more organizations are jumping on to the solar bandwagon, as the nation strives to become world’s second largest PV producer by 2020.

As electricity cost in the country continues to rise, many are turning to solar energy as an alternative and cost-effective energy. There are more uses for solar energy than one realized. For example, it can serve as a handy portable charger, allowing you to charge your devices anywhere as long as there is sunlight. With solar as an alternative energy, it will help the country save a lot of money that initially went to conventional energy consumption.

Below shows why everyone should consider turning to solar energy system as the alternative energy source.

Benefits of installing in Solar PV system

  1. It is inexhaustible. The sun is a free and inexhaustible source of energy. The sunlight cannot be monopolized by anyone nor does it run out of sun rays no matter how much solar PV takes in from it. Unlike fossil fuels where it is non-renewable and release greenhouse gas, solar PV convert sunlight into electricity with needing to burn anything. Therefore, it also makes solar energy a clean energy.
  2. It is economical. Solar energy helps reduce electricity bills. As was mentioned, the sun is free, there is no cost for excavation or transportation that often incurred when relying on fossil fuels. In Malaysia, companies could to sell their surplus energy to government-linked electricity company, TNB.
  3. It is sustainable. The lifespan for solar PV panels can last beyond 25 years and has low maintenance and operating cost because the system was built to sustain through years and decades.
  4. It paves the way for more technology advancement. Solar energy does not merely solve the climate change issue but it also opens a new avenue for the world to rethink power and electricity. Within Malaysia, the growing industry of Solar is constantly seeing improvement in their systems.

Around the world, we can see a constantly competition in improvement the solar technology, from self-cleaning panels, to the battle for higher efficiency, to recently, where triboelectric nanogenerator (TENG) was added to solar technology, where it is now possible for a solar panel to generate electricity from raindrops (it is yet to be commercialized).

Simply put, the introduction of solar technology is also opening new and better inventions into a nation.

 

It is important to point out that solar powered electricity is not inferior to fossil fueled electricity, as solar power too can be used to generate a variety of appliances from households to industrials.

While it may seem to be a Herculean task to transformed a nation that is driven by fossil energy to solar powered one; and it may seem to be a massive financial commitment in the short term, but in the long term, the country as a whole will yield much more in return both financially, culturally and environmentally.

With solar energy trending and gaining popularity, we are seeing the skepticism of the public decreases as more are being educated on renewable energy and climate change. Rooftop panels, car park panels and solar forms are some of the Solar PV projects that are rapidly in Malaysia.

With TNB (Tenaga National Berhad) too has been heavily involved in some of the large-scale solar projects (LSS) in Malaysia, it is a clear indication that solar energy is here to stay and expand.

Solar Power is Now the Cheapest Form of Energy in Almost 60 Countries

Solar power has been verified as the cheapest source of new energy in lower-income countries, allowing corporations and governments to prioritize it compared to coal and gas for renewable sources.

According to Bloomberg New Energy Finance (BNEF) in 2016, the average price of solar energy in almost 60 countries dropped to US$1.65 million per megawatt while placed first is the wind at US$1.66 million per megawatt. The cost of solar power depends on the availability of sunshine, energy contracts that are in place and government subsidies, since it is still not the cheapest source around the world.

The service has been expanding due to its dropping costs of equipment, growing investment and business corporations like Solarvest that provides top-notch installation proves on the solar PV system.

Panda Green Energy completes first panda-shaped PV power plant

Panda Green Energy Completes First Panda-Shaped PV Power Plant

China-based renewable energy developer and owner Panda Green Energy Group (PGEG), formerly United Photovoltaics said it had completed and grid-connected the first panda-shaped PV power plant in Datong County, Shanxi Province, China.

The 50MW plant also includes a youth activity centre dedicated by United Nations Development Programme (UNDP) to promoting youth participation in sustainable development. PGEG has teamed with UNDP to build panda-shaped PV power plant in China and other parts of the world, notably the ancient network of trade routes by sea and overland from China to Europe, such as the Silk Road.

This first panda-shaped PV power plant is expected to generate electricity equivalent to the reduction of approximately 60,000 tons of carbon dioxide emission each year.

Sadly, actual pictures of the plant (at time of posting) were not available on PGEG’s website, due it being upgraded and amended due to the recent name change.

Wind and Solar to ‘Dominate’ Future of Electricity by 2040

Renewable energy is indeed the future, according to Bloomberg New Energy Finance’s latest report, which forecasts technologies such as wind and solar to “dominate” the future of electricity by 2040, making up 48% of the world’s installed capacity and 34% of electricity generation.

“This year’s report suggests that the greening of the world’s electricity system is unstoppable, thanks to rapidly falling costs for solar and wind power, and a growing role for batteries, including those in electric vehicles, in balancing supply and demand,” said Seb Henbest, lead author of NEO 2017 at BNEF.

Renewable energy-generated electricity will rise 169% by 2040, and reach 74% penetration in Germany, 38% in the US, 55% in China and 49% in India.

BNEF’s New Energy Outlook (NEO) predicts US$7.4 trillion to be invested in new renewable energy plants by 2040 also; which is 72% of the US$10.2 trillion that is projected to be spent on new power generation worldwide. Of that investment, solar takes US$2.8 trillion and sees a fourfold increase in capacity.

China and India account for 28% and 11% of all investment in power generation by 2040. Asia Pacific sees almost as much investment in generation as the rest of the world combined. Of this, just under a third goes to wind and solar each, 18% to nuclear and 10% to coal and gas.

Solar Specifics

The NEO details how the levelised cost of electricity (LCOE) from solar PV, which is now almost of quarter of what it was in 2009, is set to drop another 66% by 2040. By then, US$1 is expected to buy 2.3 times as much solar energy than it does today; which is significant as utility-scale solar prices have recently fallen below US$1/Watt according to GTM Research.

Furthermore, solar is already on par with coal prices in the US, Australia, Germany, Spain and Italy. By 2021, BNEF forecast that this trend will permeate into China, India, Mexico, Brazil and the UK.

On the residential side, by 2040, rooftop PV will account for as much as 24% of electricity in Australia, 20% in Brazil, 15% in Germany, 12% in Japan and 5% in both the US and India.

At the same time, utility-scale renewable energy plants will continue to grow, further reducing the need for existing coal and natural gas plants. In fact, BNEF forecast coal use in Europe will fall by 87% in Europe by 2040 and 51% in the US. However, coal will continue to grow in China by a fifth over the next decade, but is expected to reach its peak in 2026.

Global emissions too are projected to peak in 2026, but be 4% lower in 2040 than they were in 2016.

“One of the big questions for the future of electricity systems is how large amounts of variable wind and solar generation can be accommodated, and yet keep the lights on at all times,” the report reads. “Sceptics worry about ultra-cheap renewables depressing power prices and squeezing out base-load coal, gas and nuclear plants.”

Energy Storage

In order to support the increased amount of variable renewable power on the grid, energy storage – both in the form of utility-scale and small-scale battery systems – will have a big part to play in smoothing out the peaks and troughs in supply.

BNEF expects the lithium-ion battery market for energy storage to be worth at least US$239 billion between now and 2040. Utility-scale batteries will be increasingly competitive with natural gas to provide system flexibility at times of peak demand. Small-scale residential and non-residential battery systems will account for 57% of storage worldwide by 2040.

“NEO reflects the understanding our team has built up over more than a decade of how technology costs and system dynamics have evolved, and are evolving,” said Jon Moore, chief executive of BNEF. “This year’s NEO shows an even more dramatic low-carbon transition than we have projected in previous years, with steeper drops in wind and solar costs and faster growth for storage.”
