The Benefits of Solar Panels

The use of alternative Solar energy in Australia is one of the ways that allows humanity to switch to an environmentally friendly lifestyle and start taking care of the planet. The most powerful source of such solar panels energy is the sun.

Scope of solar panels

Thanks to the development of technology, solar energy is now actively used to supply satellites, space stations, research probes and other objects. On earth, solar energy is used in the construction of power plants designed to provide independent power supply:

  • Country houses that are located far from power lines.
  • Buildings for commercial, industrial purposes, consuming various amounts of energy.
  • Scope of solar panels

Types of solar panels

Polycrystalline:

The basis of the battery is a semiconductor element with a polycrystalline structure. To produce such batteries, raw materials left after the manufacture of single-crystal batteries are used.

The efficiency varies from 12 to 18%. A polycrystal will be a good solution if your goal is to get energy only to ensure the operation of small appliances and devices.

Monocrystalline:

To produce batteries from pure silicon, a crystal is grown using the Australia method. Next, the crystal is cut into thin plates, from which the battery is assembled.

The efficiency varies from 18 to 24%. The monocrystal pays off faster. This option is preferable with a small roof area.

Benefits of using solar panels

The huge energy potential of the sun. The estimate that the sun will shine for at least another 5 billion years. The development and application of solar technologies will make it possible to obtain an inexhaustible amount of alternative energy, thereby reducing the need of mankind for minerals.

The great advantage of Solar Panel in Australia is the ability to install in almost any region. Sunlight is needed to ensure operation, and air temperature has little effect on productivity.

Solar power plants do not have a negative impact on the environment.

Silent operation. The equipment has no moving parts, which is why it can be safely installed on the roofs of residential buildings.

Autonomy. If a country house is located away from power lines, the construction of a solar power plant will ensure independence from the power supply and maintain comfort.

Ease of control. The panels work in automatic mode, there is a remote-control function.

Economic expediency. On average, investments pay off in 7-13 years. The payback period depends on the size of the solar power plant and the current electricity tariffs.

Disadvantages of solar panels

In addition to the obvious advantages of using solar panels, there are also disadvantages, the impact of which, however, is quite easy to minimize.

Performance depends on the weather. Low insolation on cloudy days reduces efficiency. Installing batteries that store energy will help solve this problem.

High price. This is a relative disadvantage of solar panels because installation costs are a one-time investment that pays off quickly.

Service. Regular cleaning of the surface of the panels from dust, dirt, snow is necessary to maintain efficiency. You can do it yourself. Cleaning does not require much effort.

Installation of panels requires a large free area. This problem is solved by installing batteries on roofs, and in rare cases even on walls.

Power of photovoltaic solar panels

Peak power: The power of the photovoltaic modules is express in “peak” Watts, denoted Wc. This is the maximum power (hence the term “peak”) that the solar panel will produce under standardized conditions. This data is therefore used to compare the power of the panels with each other. A photovoltaic module generally has a power of between 375 and 500 Wp. On the technical sheets, you will also find Watt “peak” or Wp. It is strictly the same unit, expressed in English.

Real power: But be careful, the “peak” power does not quite correspond to the real power since it is placed in optimal conditions. In practice, a solar panel produces around 75% of its peak power in good conditions. You can refer to the NOCT characteristics of the datasheet, closer to the real conditions. We note for example that a 405 Wp panel produces 306 W in practice.

Power of solar panels and consumption profile

To calculate the power of its installation in a coherent way, it is therefore necessary to start by understanding its electricity consumption.

Thus, do not consider the electric heating to calculate the total power of its installation. Indeed, the electric heating intervenes in winter (lowest production) and rather at the time when there is no sun (morning and evening). The reasoning is different for an electric water heater that can schedule during the day. Consult our article dedicated to the optimization of self-consumption to find out more.

Tools to fine-tune your consumption: A simple way to understand your electricity consumption is to regularly note the “power drawn” on your Linky meter during the hours of sunshine. On the following image, the power of 287 VA corresponds to the background noise of a detached house (VA = Volt Ampere which can be considered as W for simplicity).
