Do you also have access to solar data? Eg, I am a UK homeowner w/ a recent solar installation on my roof, would be curious to see how that looks too.
- ourlordcaffeine 3y agoSheffield solar are your guys. Maybe the best publicly available one.
- helb 3y agoThe EU has this tool for viewing solar radiation data and estimating energy yields based on location & angle: https://re.jrc.ec.europa.eu/pvg_tools/en/tools.html https://re.jrc.ec.europa.eu/pvg_tools/en/tools.html The interface isn't great, but i find it pretty useful sometimes.
- robhawkes 3y agoThanks! So I don't have solar data yet but I plan to first add aggregated solar using something like Sheffield Solar. Long term I plan to predict solar generation at a project/individual level using weather data and generation models. There's some previous work in this area by others so I imagine my near future will be spent digging through various papers on the subject.
- Telemark70 3y agoPlease would you give a URL for Sheffield Solar. I found sheffieldsolar.co.uk but could not find any data within that site.

- giarc 3y agoSorry but isn't 'UK' and 'solar installation' an odd couple? My perception, based upon 40 years of western media consumption is that it's hardly sunny in the UK. I'm ready to be corrected though :)
- harg 3y agoSolar is pretty popular in the UK. Panels have reduced in cost per watt and energy bills have increased so much that it makes it worthwhile for many homes and businesses. We do get the occasional sunny day contrary to popular belief, but even on cloudy days it's possible to generate a decent amount of energy. We also have very long days in summer which can make for a decent amount of kWh/day (although the opposite is true in winter)
- robhawkes 3y agoSolar isn't an area I'm that familiar with but we have no issues generating plenty of electricity from the sun in the UK. There's a great site [1] that calculates total solar generation around the UK using a mix of real data and forecasts. We were generating at 5GW around midday and that number will only increase.

- pjc50 3y agoOut of date but: https://flatline.org.uk/daystats.html https://flatline.org.uk/daystats.html A ~4kW installation gives me up to ~25kWh on a good day in summer. The big factor is actually the precession of the seasons since I'm at 56 degrees north. Retail electricity prices are now over 30p a kWh, so anything you can do to offset that is very useful.
- ricardo81 3y agoThere is definitely an ROI, especially with recent prices (current tariffs are around 33p kWh) Then there's the likes of Ripple Energy's solar park co-op offering. The levelised cost of buying in is around 2.5p kWh, with another 2p kWh going on maintenance. The return on the 1st (and active) co-op agreement there via a wind farm is 28p kWh, no reason why the solar park would give different returns than the wind one. Here in the UK grid pricing is more or less the same nationally. Unfortunately there's much less of a return in Winter months due to higher latitudes, though in Summertime the days are longer than in many other countries.
