Borgarnes, West, Iceland is a location that can generate solar energy throughout the year, but its effectiveness varies by season. In simpler terms, it's like having a car that works best in some weather conditions and not so well in others.

During summer, you'll get the most power from your solar panels – about 4.64 kilowatt-hours for each kilowatt of solar you have installed every day. That's pretty good! Spring isn't too far behind with 3.66 kWh/day per kW of installed solar.

However, autumn and winter are another story. In autumn, you'll only get about 1.10 kWh/day per kW of installed solar; winter is even worse at just 0.26 kWh/day per kW of installed solar.

So if you're thinking about when to rely on your solar panels for power at this location, summer and spring are your best bets.

Now let's talk about how to set up your panels for maximum efficiency all year round at Borgarnes: You'd want to tilt them towards the South at an angle of 53 degrees from horizontal level (like adjusting a beach chair to catch more sun).

But remember we're dealing with real life here – not everything is going to be perfect all the time! There could be factors like local weather patterns or physical features in the landscape that might affect how much sun your panels can catch.

For instance, Borgarnes has long hours of darkness during winter months due to its high latitude which would limit sunlight access for PV systems during these times. Additionally, it experiences frequent cloud cover which could reduce sunlight exposure on less optimal days as well as occasional snowfall which could cover and therefore block PV systems temporarily until cleared off.

To deal with these issues:

1) You might consider installing tracking mechanisms on your panels so they can follow the sun across the sky and catch more light (although this adds cost).

2) Regular maintenance to clear off any snow or debris from the panels would also be necessary.

3) Also, using solar panels that perform better in low light conditions could help mitigate effects of frequent cloud cover.

Remember, every location has its pros and cons for solar energy – it's about making the most of what you've got!

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 19 locations across Iceland. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Seasonal solar PV output for Latitude: 64.535, Longitude: -21.9155 (Borgarnes, Iceland), 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:

Average 4.64kWh/day in Summer.

Average 1.10kWh/day in Autumn.

Average 0.26kWh/day in Winter.

Average 3.66kWh/day in Spring.

Ideally tilt fixed solar panels 53° South in Borgarnes, Iceland

To maximize your solar PV system's energy output in Borgarnes, Iceland (Lat/Long 64.535, -21.9155) throughout the year, you should tilt your panels at an angle of 53° 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.

At Latitude: 64.535, Longitude: -21.9155, the ideal angle to tilt panels is 53° South

Seasonally adjusted solar panel tilt angles for Borgarnes, Iceland

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 Borgarnes, Iceland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 53° South tilt angle throughout the year.

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 Borgarnes, Iceland

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 Borgarnes, Iceland.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Borgarnes, Iceland

The topography around Borgarnes, Iceland is generally flat and low-lying. The area is mostly covered in grassy plains with some small hills and rocky outcrops. Areas that are most suitable for large scale solar PV installations would be the flat plains and open areas around the city, as these provide the most direct access to sunlight throughout the day. Additionally, areas close to roads or other infrastructure would be ideal for easy installation and maintenance of solar panels.
