Greenford, England, United Kingdom is a decent location for generating solar energy throughout the year, but it's not ideal. The amount of electricity you can produce with solar panels varies depending on the time of year. In summer and spring, you can expect to generate more power - around 5.13 kilowatt-hours (kWh) and 4.36 kWh per day respectively for each kilowatt (kW) of solar panels installed. During autumn and winter, this drops significantly to about 2.31 kWh and 1.07 kWh per day respectively.

This means that if you're looking to generate a lot of solar energy in Greenford, England, your best bet would be during the longer daylight hours in spring and summer when sunlight is abundant.

To get the most out of your solar panels all year round at this location, they should ideally be tilted at an angle facing 44 degrees South.

However, there might be some factors that could potentially hinder your ability to generate maximum power from your solar installation in Greenford:

Firstly, like many parts of the UK, Greenford experiences a fair amount of cloud cover which could reduce how much sunlight reaches your panels particularly during winter months.

Secondly, dust or debris collected on the surface of your panel may also affect its efficiency by blocking sunlight.

Lastly but importantly too are potential obstructions such as tall buildings or trees that may shade your panel from direct sunlight especially if these are located southward where panel faces towards

You can overcome these issues by ensuring regular cleaning maintenance is carried out on your panels to remove any dirt build-up; trimming trees or removing any other obstructions causing shading whenever possible; considering adjustable mountings so you can change tilt angles seasonally for better exposure to sun rays during less sunny periods like autumn/winter.

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 763 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 Greenford

Seasonal solar PV output for Latitude: 51.5263, Longitude: -0.3559 (Greenford, 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:

Average 5.13kWh/day in Summer.

Average 2.31kWh/day in Autumn.

Average 1.07kWh/day in Winter.

Average 4.36kWh/day in Spring.

Ideally tilt fixed solar panels 44° South in Greenford, United Kingdom

To maximize your solar PV system's energy output in Greenford, United Kingdom (Lat/Long 51.5263, -0.3559) 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.

At Latitude: 51.5263, Longitude: -0.3559, the ideal angle to tilt panels is 44° South

Seasonally adjusted solar panel tilt angles for Greenford, 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 Greenford, United Kingdom. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 44° 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 Greenford, 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 Greenford, United Kingdom.

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 Greenford, United Kingdom

Greenford is located in the West London region of the United Kingdom. The area's topography is relatively flat with gentle undulations, typical for urban areas in this part of England. It has a mix of residential, commercial and industrial properties interspersed with open green spaces.

For large-scale solar PV installations, open, flat or gently sloping lands are ideal as they provide maximum exposure to sunlight and ease of installation. In Greenford's vicinity, potential suitable locations could be:

1. Open fields or farmland: Northolt and Greenford Countryside Park or other nearby farms might be suitable if regulations permit.
2. Industrial rooftops: Large warehouses or factories often have extensive rooftop space that can accommodate solar panels.
3. Brownfield sites: Unused industrial land could also be repurposed for renewable energy generation.

However, it must be noted that actual suitability would depend on several factors including local planning regulations, grid connectivity and environmental impact assessments among others.

In terms of geographical orientation for maximum sun exposure in UK conditions (where the sun moves across the southern sky), south-facing locations are considered most optimal for solar panel installation followed by east or west-facing orientations which can still capture significant amounts of sunlight especially during summer months when days are longer.

Lastly it’s important to consider that London does experience variable weather conditions with cloud cover potentially impacting solar output so a thorough site-specific feasibility study would need to be undertaken before proceeding with any large scale installations.

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.
