Solar PV Analysis of Dartmouth, Canada
Dartmouth, Nova Scotia, Canada is in a location that can generate a decent amount of energy from solar panels throughout the year, but it's not ideal. The best time to generate solar energy in Dartmouth is during the summer and spring seasons when there are more daylight hours. In summer, you can expect around 5.91 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of installed solar panels. Spring also provides good conditions with about 5.06 kWh/day per kW.
However, during autumn and winter months, the output drops significantly because of shorter days and less sunlight. You can expect about 2.99 kWh/day per kW in autumn and only 1.94 kWh/day per kW in winter.
For fixed panel installations at this location, tilting the panels at an angle of 39 degrees towards the south will maximize total year-round production from your solar photovoltaic (PV) system.
There could be some local factors that might affect how much energy you can generate from your solar PV system in Dartmouth:
1) Weather: Dartmouth experiences significant seasonal variation with long winters which could limit sunlight exposure to your panels.
2) Environmental: Snow accumulation on panels may reduce their efficiency.
3) Topography: Depending on where you live within Dartmouth, Nova Scotia, surrounding buildings or trees might block sunlight to your panels.
To counter these issues:
- Regularly clean off snow or debris from your panels.
- Install them at a place where they get maximum sun exposure throughout the day without any obstructions like buildings or trees.
- Use high-quality equipment designed for colder climates which are more resistant to harsh weather conditions.
In conclusion, while Dartmouth isn't the most ideal location for generating power via solar PV due to its long winters and potential obstructions; with careful planning and maintenance it's still possible to harness a considerable amount of energy especially during spring and summer.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 569 locations across Canada. 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 Dartmouth
Seasonal solar PV output for Latitude: 44.6747, Longitude: -63.5094 (Dartmouth, Canada), 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 39° South in Dartmouth, Canada
To maximize your solar PV system's energy output in Dartmouth, Canada (Lat/Long 44.6747, -63.5094) throughout the year, you should tilt your panels at an angle of 39° South 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 Dartmouth, Canada
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 Dartmouth, Canada. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 28° South in Summer | 48° South in Autumn | 59° South in Winter | 37° South 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 Dartmouth, Canada
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 Dartmouth, Canada.
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 Dartmouth, Canada
Dartmouth is located in the Halifax Regional Municipality of Nova Scotia, Canada. The topography around Dartmouth is a mix of urban and suburban areas with numerous lakes and rivers. The land is relatively flat to gently rolling with some hilly areas.
The area has a moderate coastal climate, which may not be as ideal for solar power production as more arid regions, but it's still possible to generate solar energy here. In terms of specific locations for large-scale solar PV installations, it would depend on several factors including land availability, proximity to transmission lines, and local regulations.
Generally speaking though:
1) Open fields or farmland could be suitable as they offer large uninterrupted spaces that receive direct sunlight throughout the day.
2) Rooftops of large commercial or industrial buildings could also work well because these structures often have significant unshaded surface area that can be utilized.
3) Brownfield sites or reclaimed lands such as old industrial sites or landfills might also provide good opportunities because they are often unsuitable for other types of development but can accommodate solar panels.
4) Areas near existing power infrastructure would also be advantageous to minimize the costs associated with connecting the solar farm to the grid.
However, a detailed feasibility study would need to be conducted before deciding on any specific site. This would involve evaluating not just the physical characteristics of potential locations but also economic factors (like cost), environmental considerations (such as impact on wildlife), and social aspects (including potential community opposition).
Canada solar PV Stats as a country
Canada ranks 23rd in the world for cumulative solar PV capacity, with 3,630 total MW's of solar PV installed. This means that 0.70% of Canada's total energy as a country comes from solar PV (that's 38th in the world). Each year Canada is generating 96 Watts from solar PV per capita (Canada ranks 40th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Canada?
There are several incentives for businesses to install solar power systems in Canada. These incentives vary by province and can include:
