How Do Solar Panels Work?

Are you thinking of getting some solar panel quotes but are unsure of how exactly solar panels work? A solar panel simply works by giving permission to photons to knock electrons free from atoms. Photons are essentially just particles of light, and when these electrons are broken away from the atoms they will then produce a flow of electricity. While a solar panel may look very large, it is actually made up of lots of smaller sections and these are called photovoltaic cells. These photovoltaic cells work by converting the light from the sun into electricity. It is lots of these cells linked together that form a solar panel.

A great way to explain a photovoltaic cell is to compare it to a sandwich. This sandwich is created using 2 sections of a semiconducting material, which in most cases you will find that it is silicon used, and this is the same material that is used in microelectronics.

For a solar panel to work, the photovoltaic cells need to create an electric field. An electric field is simply a place in which the opposite charges are separated. To create this field, the builders of solar panels must dope the semi-conducting material with one or more other materials and this means that each slice of the sandwich will contain either a positive or a negative charge.

Phosphorous is seeded into the top layer of silicon and this provides additional electrons containing a negative charge to that layer. The bottom layer receives an injection of boron which takes away electrons and provides a positive charge. When both of these tasks are carried out, this creates an electric field ay this junction in between these semi-conducting material layers. A photon of light from the sun can then push an electron free, and this field pushes the electrons out of the semi-conducting material junction.

Conductive metal plates along the edge of the cells will also pick up electrons and take them to the wires. Once this has been completed, the electrons then flow in a current of electricity.

There are many solar advantages and disadvantages, and here we are taking you through more of the information that you need to decide whether solar energy quotes are the right option for you.

How to Clean Solar Panels?

What many people love about solar panels is that there are no moving parts to them and so they only require minimal maintenance to ensure that they are in the best working condition that they can be. One thing that you will need to bear in mind when getting your solar panels quote, however, is that they will need to be cleaned regularly.

Cleaning solar panels is not a difficult job and the first thing that you will need to do is check with your solar panel manufacturer on their recommendations for cleaning their specific solar panels. So, if you are looking for fuss free solar panels that can be very easily cleaned, check this out when you are looking at solar panel comparisons and getting your solar system quotes. If you neglect your solar panels and do not clean them regularly, you can potentially lose up to 25% of their efficiency which is not going to be cost-effective to you as you will have to source this other energy from a utility company with increased rates. Spring is usually the best time to clean your solar panels and you should try and clean them at least once a year, twice if you live in an area with heavy pollution.

Solar panels become extremely, extremely hot in the warmer weather and so you will want to choose a time of day, for example,

first thing in the morning, to clean your solar panels Then, try using your garden hose to remove most of the dust and dirt. If it still needs a more in-depth clean, simply full up a bucket with some warm soapy water and clean the surfaces with a sponge. There is no need to clean any of the bottom wiring.

How Many Solar Panels Do I Need?

When you are looking at solar power quotes, you will need to factor in how many solar panels that you need to receive accurate energy quotes. How many solar panels you need is entirely personal and below we can help you to work out how many you will need for your solar quotes.

The first thing to address is that you won’t make much money from providing electricity back into a grid and so you will need to try and maximise your own use of solar power as much as you possibly can! Then to work out the sizing of your new solar panels to fit your home’s needs, you will need to work out how much electricity your home uses, how much roof space you have, inverters, batteries, the grid connection and the off-grid connection.

While you may be thinking that you will automatically want to compare solar panels with a higher rated output, this is not always the most cost-effective and efficient way to get the best solar quote. You will need to consider how much space you have available on your roof and also how much space you have on the side of your roof facing north as this is prime for sunlight. You will need to find that most solar panel reviews comparisons are based on those around 1.6 square metres in area size. However, the bigger the power rating and power output is, then the less panels you will potentially need to get the amount of power that your home requires.

When looking to compare solar panel deals, we would also recommend that you compare solar panel prices based on the whole system and not just simply the panels. Having fewer panels that are more powerful may appear on first glance to be more expensive; however, having fewer panels means faster installation and so to get accurate solar panel quotes online, remember to factor this is.

  1kW 2kW 3kW 4kW 5kW 10kW
Number of Panels (Estimated) 3 to 4 6 to 8 9 to 12 12 to 16 15 to 20 30 to 40
Area Required m2 (Estimated) 5 to 7 10 to 15 15 to 20 20 to 27 25 to 35 50 to 70


How Much Do Solar Panels Cost?

Solar panel costs vary greatly from person to person depending on their energy needs, the quality of components used and the size of the system. The Alternative Energy Association released figures stating that the overall average cost of a 2.0kW system that is fully installed in 2013 was around $4400. However, this price is before any rebates or discounts, such as the solar panel rebates Victoria. Larger systems will cost you more when looking for a solar panel quote. Other figures have shown that in 2014, the average paid after rebates and discounts was $8243 which is quite a large difference. This large price difference is most likely due to the system sizes that are being installed as around 90% of those who had a solar power quote and had fitted a solar system, it was over 2.0kW. Furthermore, a massive 49% of installed systems were over 4.1kW, which is quite large when you compare solar panels Australia. The prices shown in the following table are based on the average out of pocket costs and system size in May 2018.

  1.5kW 2kW 3kW 4kW 5kW
Sydney $2820 $3270 $4070 $4750 $5420
Melbourne $3080 $3790 $4350 $5230 $5980
Perth $2500 $2760 $3390 $4090 $4580
Adelaide $2900 $3490 $4140 $4730 $5270
Canberra $3180 $3550 $4140 $4920 $5410

What Are Solar Panels Made Of?

The majority of solar panels that you will find when you are looking at solar comparison quotes are made of silicon. The solar panels are created with lots of solar cells and these are usually sandwiched together between protective glass and backing plates. You will then typically find that the entire solar panel is surrounded by an aluminium frame.

How Long Do Solar Panels Last?

Manufacturer warranties on solar panels vary, but the best solar panel companies will provide manufacturer warranties of up to 25 years. So, your solar panels should last for at least this length of time and when you are looking to compare solar quotes, it is a good idea to take this into consideration and compare solar companies warranty’s too. For the product itself, you can also typically expect to receive a ten to twelve-year warranty while the installer may give you an additional warranty for the workmanship.

What Are the Best Solar Panels?

We understand that when looking at solar panel comparison, it can quickly become confusing as there are many different types for you to choose from. Here, we are taking you through the main three types – mono, polycrystalline and thin film.

  • Monocrystalline Silicon Solar Cells – These solar panels are instantly recognisable from their even colouring and uniform look. These cells are made from silicon ingots and fours sides will by cut out of these ingots which optimises performance and lowers the cost.
  • Polycrystalline Silicon Solar Cells – These solar panels were first introduced back in 1981 and the Czochralski process isn’t needed. The raw silicon is melted and then poured into square moulds. These are then cooled and cut into the perfect squarest that you see on rooftops.
  • Thin-Film Solar Cells -These solar panels are created by placing at least one thin layer of photovoltaic material onto a substrate. There are four types of photovoltaic material that can be used in these solar panels which are amorphous silicon, cadmium telluride, copper indium gallium selenide or organic photovoltaic cells.
