Solar PV Analysis of Cambridge, New Zealand
Cambridge, Waikato Region, New Zealand is a decent spot for generating solar energy all year round but it's not the best. The amount of electricity that can be produced from solar panels changes depending on the season. In summer, you would get about 7.08 kWh of electricity per day for each kW of installed solar power capacity, in autumn this drops to 3.86 kWh/day, in winter it's even lower at 2.50 kWh/day and then increases again in spring to around 5.23 kWh/day.
This means that the best time of year to generate solar energy at this location is during summer and spring when there are more hours of sunlight and less cloud cover compared to other seasons.
For fixed panel installations here, tilting them towards an angle of 33 degrees North will give you the most total production over the course of a year because this angle aligns better with the sun’s path across the sky.
There could be certain local factors affecting your ability to produce as much energy as possible from your solar panels though – things like weather conditions or environmental issues specific to Cambridge, Waikato Region, NZ area might reduce their efficiency.
For example, if there are frequent heavy rains or storms which may lead to debris accumulation on panels reducing their efficiency; or if there are tall trees or buildings nearby that block direct sunlight reaching your panels throughout parts of the day - these things can all affect how much energy you're able to generate from your installation.
To counteract these potential problems:
1) Regular cleaning and maintenance should be done especially after storms.
2) If shading is an issue due either trees or structures blocking sunlight onto your panels then consider trimming back branches where possible; relocating any moveable objects causing shade; or installing additional panels elsewhere on property where they'll receive full sun exposure.
3) And lastly remember: Even though Cambridge isn't optimal for solar PV generation compared with some other places globally - every bit counts and it's definitely better than not using renewable energy sources at all!
Note: The Southern Temperate Zone extends from -35° latitude South down to -66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 105 locations across New Zealand. 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 Cambridge
Seasonal solar PV output for Latitude: -37.8887, Longitude: 175.4695 (Cambridge, New Zealand), 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 33° North in Cambridge, New Zealand
To maximize your solar PV system's energy output in Cambridge, New Zealand (Lat/Long -37.8887, 175.4695) throughout the year, you should tilt your panels at an angle of 33° 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 Cambridge, New Zealand
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 Cambridge, New Zealand. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 22° North in Summer | 43° North in Autumn | 53° North in Winter | 31° 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 Cambridge, New Zealand
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 Cambridge, New Zealand.
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 Cambridge, New Zealand
Cambridge, New Zealand is located in the Waikato region on the North Island. The topography of this area is relatively flat with gently rolling hills, making it ideal for agriculture. There are also several rivers and streams that run through the area including the Waikato River.
When considering large-scale PV installations, there are a few factors to consider such as land availability and suitability, proximity to power grids or demand centers etc.
Given Cambridge's relatively flat terrain, large open spaces such as farmlands could be potential sites for large-scale PV installations. However, considerations would need to be made around land use conflicts with existing agricultural activities.
Furthermore, roof-mounted systems on industrial buildings in nearby urban centres like Hamilton could also be viable options given their close proximity to electricity demand centers.
However, these suggestions would still require detailed feasibility studies including technical aspects (like system efficiency), economic viability and environmental impacts before any concrete decisions can be made.
New Zealand solar PV Stats as a country
New Zealand ranks 78th in the world for cumulative solar PV capacity, with 146 total MW's of solar PV installed. Each year New Zealand is generating 29 Watts from solar PV per capita (New Zealand ranks 58th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in New Zealand?
Yes, there are several incentives for businesses wanting to install solar energy in New Zealand. The government offers a range of grants and subsidies to help businesses reduce their energy costs and increase their use of renewable energy sources. These include the Solar PV Grant Scheme, which provides up to $20,000 per installation towards the cost of installing solar photovoltaic (PV) systems; the Low Emission Vehicles Contestable Fund, which provides funding for electric vehicles; and the Energy Efficiency and Conservation Authority’s Business Energy Management Programme, which helps businesses identify ways to save money on their energy bills. Additionally, some local councils offer rates rebates or other incentives for businesses that install solar panels.
