As more Australians consider switching to renewable energy, understanding how solar panels work can help homeowners make informed choices. In this article, we’ll break down the science behind solar power, explain why Australia is one of the best countries for solar energy, and discuss which solar panel materials perform best in the Australian climate.
The Science: Sunlight and Electrons
At the core of every solar panel is the photovoltaic (PV) effect, a process where sunlight is converted into electricity.
When sunlight (photons) hits the panel’s surface, it energizes electrons in the silicon cells, knocking them free.
These freed electrons flow through the circuit, creating direct current (DC) electricity.
An inverter then converts this DC power into alternating current (AC), which powers your home appliances.
This is a clean, silent, and scalable method of generating electricity.
Australia’s Solar Advantage: Abundant Sunlight
Australia is a global leader in solar potential, thanks to its:
High solar irradiance levels – most parts of Australia receive over 2,000 kWh/m²/year.
Long hours of daily sunshine – averaging 5 to 7 hours of peak sun across major cities like Brisbane, Perth, Adelaide, and Sydney.
This makes Australia not just ideal for solar energy, but one of the most cost-effective regions for solar system investments.

As more New Zealanders look to reduce their electricity bills and carbon footprint, solar energy has become an increasingly attractive solution. But how exactly do solar panels work, and which types are best suited to Aotearoa’s unique weather and sunlight conditions? This article explains the basics of solar technology and what to consider when choosing a solar panel system for your Kiwi home.
The Basics: How Solar Panels Turn Sunlight into Electricity
Solar panels generate electricity through the photovoltaic (PV) effect:
Sunlight (composed of particles called photons) strikes the solar panel surface.
This energy knocks electrons loose from atoms in the panel’s semiconducting material (usually silicon).
The movement of these electrons generates direct current (DC) electricity.
An inverter then converts DC to alternating current (AC), which powers your home.
It’s a clean, silent, and renewable process—ideal for homeowners looking to take control of their power usage.
Sunshine in New Zealand: Is It Enough?
Though not as sun-drenched as Australia, New Zealand still has plenty of solar potential, especially in areas like:
Nelson, Blenheim, and Bay of Plenty, which receive more than 2,000 sunshine hours annually.
Even in Wellington or Auckland, solar systems can be effective year-round, especially during summer and spring.
Cloud cover and shorter winter days do affect output, but modern panels are efficient enough to generate power even on overcast days.
Best Solar Panel Materials for New Zealand’s Climate
New Zealand’s environment is diverse—coastal air, frequent rain, and UV exposure all play a role in solar performance and system longevity.

As utility prices rise and sustainability becomes a household priority, more Americans are turning to solar energy. But how do solar panels actually work? And which panel types are best suited for different parts of the country—from sunny Arizona to rainy Seattle? This article walks through the basics of solar technology and the best choices for U.S. homeowners.
The Science: Turning Sunlight into Electricity
Solar panels generate electricity through the photovoltaic (PV) effect:
When sunlight hits a solar panel, energy from the light particles (photons) dislodges electrons in the silicon-based cells.
This movement creates direct current (DC) electricity.
A solar inverter converts DC to alternating current (AC), which your household appliances use.
This process is clean, quiet, and generates no emissions—making it a powerful tool in the shift toward renewable energy.

With energy costs rising and climate concerns growing, more Canadians are considering solar energy. But how exactly do solar panels work, and are they effective in Canada’s often cold and snowy climate? Let’s explore the science behind solar power and how to choose the best panels for your region.
The Basics: From Sunlight to Electricity
Solar panels convert sunlight into usable power through the photovoltaic (PV) effect:
Photons (light particles) from the sun hit the solar panel and dislodge electrons in the cells.
This generates direct current (DC) electricity.
An inverter converts DC into alternating current (AC) electricity for household use.
This entire process happens silently, without moving parts, and produces no emissions.
How Much Sun Does Canada Get?
Although Canada is known for its cold winters, many regions receive enough sunlight to make solar worthwhile:
Southern Alberta, Saskatchewan, and Ontario receive over 2,000 hours of sunshine per year—comparable to parts of Germany, a solar leader.
British Columbia and Atlantic Canada receive less sunlight annually, but solar still works effectively with the right panel choice.
Importantly, solar panels still generate electricity on cloudy or snowy days, just at lower efficiency.
Best Solar Panel Types for Canada’s Climate
Given Canada’s long winters, cold temperatures, and snowfall, panel durability and low-light efficiency are crucial:
Monocrystalline Panels
Highly efficient and space-saving.
Perform well in cold, sunny climates, such as Alberta or southern Ontario.

By choosing the right panel type—whether monocrystalline for efficiency or bifacial for snow-heavy regions—Canadian homeowners can take a big step toward energy independence, environmental sustainability, and long-term cost savings.
Now is the time to explore solar energy, especially with national incentives supporting your investment.
When it comes to installing a solar power system for your home in Australia, most homeowners focus on sunlight availability and the cost of the system. However, Land Surface Temperature (LST) — the temperature of the ground and surfaces that solar panels are mounted on — is often overlooked, despite playing a critical role in the performance and lifespan of solar technology.
Let’s explore why understanding LST is essential in Australia, a country known for its intense sun and diverse climate zones.
The Relationship Between Heat and Solar Panel Efficiency
Solar panels are powered by light, but their efficiency drops as their surface temperature rises. This is due to the temperature coefficient — a percentage that tells you how much power the panel loses for every degree above 25°C. On average:
For every 1°C increase, a panel may lose 0.3% to 0.5% efficiency.
If a panel reaches 45°C — which is common on rooftops in Australia — efficiency loss can be 6-10% or more.
So while high sunshine is great, high surface heat can seriously affect your energy yields.
Australia’s Climate Zones and Surface Temperatures
Australia spans a range of climates, and with them, major differences in land surface temperatures:
Region
Climate Type
LST Characteristics
Northern Australia (NT, QLD)
Tropical
Very high LST year-round, often exceeding 45–50°C
Central Australia
Arid/Desert
Extremely high LST, low humidity, sharp day-night contrast
Eastern Seaboard (NSW, VIC)
Temperate/Subtropical
High summer LST, mild winters
Tasmania
Oceanic
Moderate LST, less thermal stress on panels
Perth & WA
Mediterranean
High solar radiation and summer LST
Even in cooler cities like Melbourne or Hobart, summer rooftop temperatures can exceed 60°C, especially on metal roofs.

Canada’s vast landscape encompasses a wide range of climates—from the frigid Arctic tundra to temperate coastal regions and sunny inland plains. Despite its reputation for cold weather, solar power adoption in Canada is growing steadily, thanks to long daylight hours in summer and falling installation costs. But when choosing solar panels for Canadian homes, one critical but often overlooked factor is Land Surface Temperature (LST).
This article explores why understanding LST is essential for Canadian homeowners investing in solar panels, how climate differences across the country affect solar panel performance, and how to choose the best panels for long-term efficiency and reliability.
Why Land Surface Temperature Affects Solar Panel Performance
Although solar panels work better in sunlight, extreme heat can reduce their efficiency. Most panels lose a small percentage of efficiency (usually between 0.3% and 0.5% per °C) when temperatures exceed 25°C. LST reflects the actual heat of the ground surface—often higher than ambient air temperature—making it a useful indicator when evaluating long-term solar panel performance.
In Canada, while heatwaves are less common, certain regions can still reach temperatures above 30°C in summer. In contrast, very cold winters and snow cover raise questions about durability, energy yield during winter, and panel cleaning or snow shedding ability.
Climate and LST Differences Across Canadian Regions

Long daylight in summer, extreme cold in winter
In general, southern Alberta and Saskatchewan are Canada’s solar sweet spots due to abundant sunshine and dry air. Coastal BC sees less sunlight but benefits from moderate temperatures year-round.
Choosing the Right Solar Panels for Canadian Conditions
Canadian homeowners must consider:
Temperature tolerance: Panels must work efficiently during the rare hot spells in summer.
Cold durability: Panels should be built to withstand snow load, hail, and freezing temperatures.
Energy yield in diffuse light: In cloudy or foggy areas like coastal BC or the Maritimes, high-performance panels that work in low-light conditions are ideal.
Recommended solar panels for Canadian conditions:
Panasonic HIT and SunPower Maxeon: Excellent in both high and low temperatures; good for cold and snowy areas.
REC Alpha: Durable and efficient, performs well in variable lighting.
Canadian Solar HiKu: Locally produced, cost-effective, and built for Canadian winters.
Using LST Data to Optimize System Design
Homeowners can access LST data via:
Environment and Climate Change Canada (ECCC): For climate and temperature records.
NASA or Copernicus Earth Observation platforms: Satellite data on solar radiation and surface temperature.
Provincial solar maps: Some provinces like Alberta and Ontario provide solar potential maps with integrated temperature data.
This data helps:
Determine whether roof-mounted or ground-mounted systems are better (e.g., rooftops heat more than ground).
Design panel layout for maximal cooling airflow.
Select microinverters or optimizers to reduce the impact of temperature variance on system output.
LST and Long-Term Cost Benefits
In colder climates, some heat loss is actually beneficial—solar panels operate more efficiently in cooler air, as long as there’s enough sunlight. With the increased summer daylight in northern areas, homeowners can still achieve high annual output.
Example: In Calgary (Alberta), average yearly solar irradiance can support a 6 kW system producing around 8,000 kWh/year. Even with occasional summer heat, the LST stays moderate enough to keep efficiency losses low. Over a 25-year lifespan, this can result in savings exceeding $25,000 CAD, even with the cost of installation (~$15,000–$20,000 CAD after incentives).
Tailoring Solar Panel Choices to Canadian Climate and LST
Canada’s climate diversity means there’s no one-size-fits-all solar panel. Land Surface Temperature plays a critical role in selecting systems that will perform efficiently across hot summers and cold winters. Whether you live in sun-soaked Alberta or rainy Vancouver, paying attention to LST and environmental data ensures your solar panels deliver optimal energy output and cost savings over the long term.
By aligning panel technology with local LST trends, Canadian homeowners can make smart, sustainable investments in solar energy—reducing bills, increasing property value, and contributing to a cleaner environment.
