Solar PV Analysis of New Malden, United Kingdom
The location at New Malden, England, United Kingdom, is somewhat suitable for generating solar energy throughout the year, but there are better times than others. During summer and spring, you can expect more electricity output per day from your solar panels - 5.13kWh/day in Summer and 4.36kWh/day in Spring for each kilowatt of installed solar power. These seasons are ideal times to generate solar energy due to longer daylight hours and stronger sunlight.
However, during autumn and winter, the output drops significantly - down to just 2.31 kWh/day in Autumn and even lower at 1.07 kWh/day in Winter due to shorter days and less intense sunlight.
To maximize your annual production from solar PV at this location, it's recommended that you tilt your panels at an angle of 44 degrees facing South if they're fixed installations.
As far as environmental or weather factors that could impede solar production here: The UK is known for its frequent cloud cover which can reduce how much sunlight reaches the panels; winter snowfall might also cover them up temporarily reducing their efficiency until cleared off; additionally foggy conditions common in some parts of Britain may also affect visibility of the sun too.
Preventative measures that can help ensure greater energy production include regular cleaning and maintenance of your panels so they're always working optimally; installing a system with tracking capabilities so it follows the sun's path across the sky maximizing exposure (though this would be more expensive); or using advanced photovoltaic cells designed to capture more light under cloudy conditions (again potentially increasing costs).
In short while not perfect all year round New Malden does offer sufficient potential for those looking into investing into Solar PV especially during spring/summer months with few key considerations taken into account regarding panel positioning/maintenance etc.
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 911 locations across United Kingdom. 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 New Malden
Seasonal solar PV output for Latitude: 51.3997, Longitude: -0.2515 (New Malden, United Kingdom), 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 44° South in New Malden, United Kingdom
To maximize your solar PV system's energy output in New Malden, United Kingdom (Lat/Long 51.3997, -0.2515) throughout the year, you should tilt your panels at an angle of 44° 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 New Malden, United Kingdom
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 New Malden, United Kingdom. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 44° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 35° South in Summer | 55° South in Autumn | 65° South in Winter | 43° 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 New Malden, United Kingdom
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 New Malden, United Kingdom.
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 New Malden, United Kingdom
New Malden is located in the Greater London area of the United Kingdom. The topography of this region is generally flat to gently undulating, with some areas of slightly higher ground.
For a large-scale solar PV project, it would be ideal to have a flat or gently sloping area that gets plenty of sun exposure throughout the day and isn't shaded by trees or buildings. Given New Malden's urban setting, finding such an area within the town itself could be challenging due to existing infrastructure.
However, there are several open spaces in and around nearby Kingston upon Thames and Richmond Park which might be suitable for such installations if they meet other criteria (like ownership rights and local regulations). Alternatively, industrial rooftops or brownfield sites could also potentially serve as locations for solar panels.
Please note that any potential site would need detailed assessment considering factors like solar irradiation levels, grid connection possibilities, environmental impact assessments etc., before determining its suitability for large-scale solar PV installation.
United Kingdom solar PV Stats as a country
United Kingdom ranks 14th in the world for cumulative solar PV capacity, with 13,689 total MW's of solar PV installed. This means that 4.00% of United Kingdom's total energy as a country comes from solar PV (that's 20th in the world). Each year United Kingdom is generating 203 Watts from solar PV per capita (United Kingdom ranks 25th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in United Kingdom?
Yes, there are several incentives for businesses wanting to install solar energy in the United Kingdom. The UK government offers a Feed-in Tariff (FiT) scheme which pays businesses for every unit of electricity they generate from their solar panels. Additionally, businesses may be eligible for tax reliefs such as Enhanced Capital Allowances and Renewable Heat Incentives. Finally, some local authorities offer grants or other financial support to help businesses with the cost of installing solar energy systems.
