How Does Efficiency Work?

To calculate solar panel efficiency, you need to divide the wattage of the panel by the square meterage. This is the simplest way to get any solar PV module’s efficiency.


For example:
Suntech 370w panel, is 1.756m x 1.039m.
Total of 1.824484sqm.
Divided by 0.370kW is 20.3%.

Easy peasy!

Lower-efficiency panels will produce the same kWhs as high-efficiency panels, but they’ll take up a bit more space to do so. If you have the following two panels;

1. A 500w panel the size of your front door or;
2. A 500w panel the size of a microwave

Which one will produce the most?
Answer = both are the same, they’re both 500w panels.

How Do Optimised Solar Panels Work?

What is a ‘string’?

When it comes to conventional solar panel systems, the panels are connected in what is called strings. Each string will have a number of connected solar panels that are wired in a series. It looks a little something like this:

What Is A Solar Panel Optimiser?

A solar panel optimiser is a device that can be added to one or all panels in a string. Its aim is to increase the output of a solar installation, by bypassing the shaded solar module which allows the system to operate to its full potential.

Solar Panel Frequently Asked Questions:

Choosing the best solar panels is tricky. There are many brands to choose from, but It depends on your roof space, your roof shape and orientation, what size system you need and of course, your budget. We’d always recommend using tier 1 solar panel brands, as they are higher quality and more reputable.

Perth Solar Force stock many brands of panels, but ‘the best’ brand of panels, depends on the individual. Not all systems are the same, and we take that into account and build a system that is the best for you! You can contact us and we’d be happy to work out which solar panels are the best for you. Check out our solar panel brands page, for more information on the brands of panels we stock. 

Arguably, the quality of your solar panels and the inverter are the most crucial factors in selecting a solar system. Over their 25 year output (average warranty period), solar panels will be subjected to more than 100,000 hours of harsh weather extremes such as – sunshine, intense heat and cold, wind, rain, hail and more.

More importantly, solar is an investment. Like any home investment decisions, you do not want to make a hasty decision on something your will be using for 25+ years – like a car for example (although that is a very long lifespan for a vehicle), you don’t pick the first off the lot, and you certainly don’t pick the cheapest for a reason – the same applies with solar. 

With a good quality brand like Suntech for example, with proper installation and quality system checks, we can ensure you will get the most out of your system. To make things easier for you, we only offer quality brands, so you can ensure the best quality solar PV system when you install with Perth Solar Force. Please check out our solar panel brands page for more information.

The most common size solar panels for residential are 330w. This is a really good output and great efficiency for most residential homes and roofs. However there are some cases you may need a little more wattage, so we offer 415w panels as well. Your solar expert will be able to address all your questions, and help you identify what the most beneficial size panels for your household.

A 6.6kW system is typically made up of anywhere between 20 and 24 solar panels. The number of panels you need for a 6.6kW system varies depending on how much roof space you have and what size panels are used. 

Some examples of this are as follows; 

– 275w panels = 24 (6.6kW total) 

– 300w panels = 22 (6.6kW total) 

– 330w panels = 20 (6.6kW total) 

For more information, please visit our Home Solar Packages and the 6.6kW solar system page.

A 10kW system is typically made up of anywhere between 40 and 48 solar panels. The number of panels you need for a 10kW system varies depending on how much roof space you have and what size panels are used. 

Some examples of this are as follows; 

– 275w panels = 37 (10.17kW total) 

– 300w panels = 34 (10.2kW total) 

– 330w panels = 31 (10.23kW total) 

For more information, please visit our Home Solar Packages page.

Shading, dirt and bird droppings are common on most solar panel systems from time to time. These can cover some of the cells on the panels, and make it less efficient in producing solar energy.

If your system is set up on a string inverter, this can seriously effect output, as all solar output travels to and from the same string inverter. However if you have micro inverters on every panel, your system is less likely to be majorly effected, as it will just be one (or however many panels is covered in dirt etc) that will stop functioning as well. 

Rain is not a significant method of cleaning solar panels, it leaves a film across the panels, that eventually will cause a build up and minimise the efficiency.

Perth Solar Force offer a quality panel cleaning service. We use special formula cleaning products, designed especially for cleaning solar panels, to bring your system back to its original optimal output efficiency. You can give us a call if you would like more information.

It totally depends on what brand you have. Each different Solar Panel brand has a different length of warranty on their products. Most are between 12-15 years . You can check out our solar panels comparison page to find out the exact length of warranty for each brand.

Don’t forget, Perth Solar Force also provides a 10year workmanship warranty with all installations.

Every household is different. It depends on the size of your house, how many people live there, what appliances are used and what times of the day they are used. One solar panel produces about 1 kW/hr per day. working out what your daytime power usage is will give you a better idea of how many you need. It’s not really about how many panels you need, it’s more about what size system you need. 

Solar panels vary in size too, from 1.5kw panels up to over 400kw, so that is also taken into consideration. A rough estimate of how many solar panels you will need based off the majority of households, so if you use 15 units/kWh during the day, you would need approx. 15 solar panels.
