I am working on solar still as LD regenerator so want ambient data in terms of solar insolation hourly year over , wind speed in same manner
Actually in V.V.Nagar , SPRERI work on solar energy , so u will have to find research organisation , in baroda or some industry , who work on solar energy
Would you give me guidlines to request spreri to provide me the data or it is confidential for them
I think Trnsys (meteonorm) data is better , but one have to purchase. NREL have maps and data but you have to authenticate it whether they have hourly data (its free). RETScreen provide daily data (free) which can be converted to hourly one (r factor duffie).
While more simple is to find research article on science direct.
The following link would help you, i found it now :)
http://www.wunderground.com/
Search for it in Meteonorm Software .
if there is Baroda then u can purchase solar insolation, ambient Temperature , wind speed and relative humidity data from them
Can you tell which is the closest or similar weather big city of india which you can use as an alternative data.
dear sir
Already I have datas for AHMEDABAD GUJARAT INDIA
but the data related to particular can gives trong imapact
@Reza Ghezelbash there is no solar irradiation shown on the site, you reffered.
If it is possible to find out the solar irradiation from the data available on this site then kindly madeavailable it to me
hi dear,
can you please tell me for what purpose this data? and which format data you want either TMY or EPW?
Ya i want to evaluate my yield (mass of disillate) in solar still in vadodara india
i want hourly year-round solar radiation in kw/m^2/hr(or Mwh/m^2/hr)
There are different ways to generate such data by modeling, but nothing exists that is both free and accurate. Meteonorm would be the least costly source, but with an unknown accuracy. It's possible to obtain high-quality hourly data from satellite for the last 15+ years, which is the usual method used for resource assessment of large solar projects, but it's costly. Let me know how you want to pursue this,
I am a student of gujarat india
So it will be great help from you to provide me at lowest possible cost or may I say free or else .
Yes, it is possible to generate data by modeling, but the big question is accuracy: if you need good accuracy, particularly in direct hourly irradiance, and long time series (>15 years), the method is complex and must rely on satellite data. This translates into higher costs. So you need to be give more details about what you need exactly (which component, time step and time frame, acceptable uncertainty...)
Dear sir
I am working on Solar still to use it as a Liquid desiccant (CaCl2) regenerators
So I have compare he experimental data with some analytical methods which contains
hourly solar Radiation (W/m2/hr)
Hourly avg wind speed(km/hr) for the time period of 9:00 am IST to 6:00pm
for the place of Vadodara a district of Gujarat India pin code
For what period do you need all this?
