What is a Solar Panel?

What Size of Solar Panel Do I Need?

Before buying solar panels in Australia for a home, you must consider its size. You must know how much electricity you use and when you use it. A typical home uses 20Kwh of energy in a day, but a 5kW solar system can also fulfil most daytime power needs.

How Many Solar Panels Do You Need at Home?

You must know the exact number of solar panels you need at home. For that, you need to consider certain factors.

  • The power output is more important than the size of the number of panels you require.
  • High nominal rating of a solar panel is good as they will generate more output with less panels.  
  • You must consider the space of your roof. If you have plenty of space, you can buy cheaper panels. These panels are more economical with lower efficiency.
  • The panels may vary in length, width and power output. So, you must also consider this factor.

Types of Solar Panels

When you buy solar panels in Australia you must know their type. So that you can choose the panel that best fits your needs.

Monocrystalline and Polycrystalline

The cells of these two panels are made of silicon wafers. These panels are assembled into rows and columns to form a rectangle and are framed together.

Thin-film Solar Panels

Thin-film solar panels use a variety of materials. It uses a glass layer on the top for better protection. They use silicon but are not made of silicon wafers. Owners with a lot of space can use these panels. 

Bifacial Solar Panel

These panels can capture sunlight from both front and back. These have transparent back sheets to reflect sunlight on the ground surface. Moreover, the sunlight gets reflected on the backside of the panel.

Are Solar Panels Efficient?

Solar panels are very efficient as they don’t need direct sunlight to work. They can produce a considerable amount of electricity on cloudy days and during winters.

Certain factors can affect the efficiency of your solar panels. These solar panels are more efficient during the summer months, but they are also good to work in winter. Their power is measured in kilowatt-hours [kwh].

Factors Affecting Efficiency of Solar Panels

While buying solar panels for home, you must consider their efficiency. Moreover, there are a number of factors that can affect the efficiency of solar panels.

  • Location, Angle and Direction

Assessing a roof’s suitability to hold a solar panel is essential. Angles of the roof determine how much sunlight exposure your panel will get. 

  • Roof Suitability

The roof should be strong enough to support the weight of a solar panel. Slate and wooden roofs can be brittle. You must consider if the roof is large enough to have a solar panel. You need at least 30 cm of space around a solar panel.

  • Size of Solar Panel System

The bigger the solar panel system the bigger the capacity to generate more electricity. Solar cells have varied shapes and sizes. You can have an estimate of the solar panel’s size with your electricity needs.

  • Maintenance

Maintaining a solar panel nicely can enhance its lifespan. You must get your panels checked regularly by the installer or service provider.  You should clean solar panels regularly and avoid sponging them or touching them.
