Solar PV Analysis of Kempsey, Australia
Kempsey, New South Wales, Australia is a decent location for generating solar energy throughout the year. Solar power generation depends on sunlight, and the amount of sunlight this area gets varies by season.
In summer, each kilowatt of installed solar can generate about 6.55 kilowatt-hours per day. This decreases in autumn to 4.33 kilowatt-hours per day and further drops in winter to 3.62 kilowatt-hours per day due to shorter days and less direct sunlight. However, it increases again in spring with around 5.87 kilowatt-hours generated per day.
So, Kempsey experiences its peak solar energy production in summer when days are longer and sunnier but still maintains a reasonable output during other seasons as well.
For optimal results at this location, it's recommended that fixed panel installations be tilted at an angle of 28 degrees facing North to maximize exposure to the sun throughout the year.
As for potential obstacles affecting solar production at this location, these could include environmental factors such as cloud cover or rainfall which may reduce the amount of sunlight reaching panels; topography like hills or trees which might block sunlight; or local weather patterns if Kempsey has long periods of overcast skies or heavy rainstorms.
To mitigate these issues:
1) Install panels where they won't be shaded by buildings or vegetation.
2) Keep panels clean so they can absorb maximum light.
3) Consider using tracking mounts that follow the sun's path across the sky for better efficiency.
4) If heavy rainfall is common, ensure proper drainage around your installation site so water doesn't pool and damage your system.
Remember though that while these measures can help improve performance under challenging conditions, every site has unique characteristics that will affect overall productivity – so it’s always best to seek professional advice before installing a system!
Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 501 locations across Australia. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Kempsey
Seasonal solar PV output for Latitude: -31.0804831, Longitude: 152.8418039 (Kempsey, Australia), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 28° North in Kempsey, Australia
To maximize your solar PV system's energy output in Kempsey, Australia (Lat/Long -31.0804831, 152.8418039) throughout the year, you should tilt your panels at an angle of 28° North for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Kempsey, Australia
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Kempsey, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 28° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 15° North in Summer | 37° North in Autumn | 46° North in Winter | 25° North in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Kempsey, Australia
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Kempsey, Australia.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Kempsey, Australia
Kempsey is located in the Macleay Valley on the Mid North Coast of New South Wales, Australia. The topography of Kempsey and its surrounding areas is quite varied, with coastal plains, rolling hills, mountain ranges and river valleys.
The coastal plains around Kempsey are relatively flat and would be suitable for large-scale solar PV installations. These areas have good solar irradiation levels due to their geographical location and lack of shading from mountains or tall buildings.
In addition to this, there are also some cleared agricultural lands in the area that could potentially be used for solar farms without causing significant disruption to local ecosystems or farming activities. These include areas around West Kempsey and Frederickton.
However, it's important to note that any large-scale solar project would need to take into account a range of factors beyond just topography - including environmental impact assessments, local planning regulations and community consultation processes.
Australia solar PV Stats as a country
Australia ranks 7th in the world for cumulative solar PV capacity, with 19,076 total MW's of solar PV installed. This means that 10.70% of Australia's total energy as a country comes from solar PV (that's 2nd in the world). Each year Australia is generating 742 Watts from solar PV per capita (Australia ranks 2nd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Australia?
Yes, there are a variety of incentives available in Australia to businesses wanting to install solar energy. These include:
1. Renewable Energy Target (RET): The RET provides businesses with financial assistance for installing and operating renewable energy systems such as solar panels. Businesses may be eligible to receive certificates that can be sold or traded on the open market for additional income.
2. Feed-in Tariffs: Some states offer feed-in tariffs which pay businesses for generating and exporting excess electricity from their solar panel system back into the grid during peak demand periods.
3. Solar Credits: The Solar Credits program provides households and small business owners with an upfront discount when purchasing a new solar system, based on the amount of renewable energy generated by the system over its lifetime.
4. Tax Breaks: Small business owners may be able to claim tax deductions on certain expenses associated with installing a solar power system, including installation costs, maintenance expenses and interest payments related to financing arrangements taken out specifically for this purpose.
