How can I easily calculate daily and monthly solar radiation from experimental data given as in every 10-minutes interval of time or every hour?
consider day length 10 hours and data are given in W/m2
Can I directly implement the average function in Excel or is there some other way we can do it?
Check the following open access paper:
Mousavi Maleki, Seyed Abbas, H. Hizam, and Chandima Gomes. "Estimation of hourly, daily and monthly global solar radiation on inclined surfaces: Models re-visited." Energies 10, no. 1 (2017): 134.
Dear, Chhotelal Prajapati
In this link you will be able to find information on the daily, monthly and annual solar radiation levels of the regions of the world that you want to analyze. I hope it is useful for you.

Dear, Chhotelal Prajapati you can check the following open-access paper: "A Theoretical Investigation of Solar Radiation and Heat Transfer in a Solar Pond in Karbala City" to calculate the monthly average daily global radiation.
Dear Sir, Thanks for your suggestion, my question is different, I already have experimental data, here I theoretically do not want to find solar radiation. Just want to know that if we have data every 10-minutes interval and the day length is 10 hours, what is the average daily solar tradition? Does it get average full-day data or only consider peak day values?
The daily irradiation in Wh/m2 will be obtained as the sum of all hourly values in W/m2. For instance, if the irradiance is constant at 100 W/m2 during 10 hours, the daily total irradiation is 1000 Wh/m2=1 kWh/m2.
The same principle applies to 10-min values, but then the total needs to be divided by 6. So if the irradiance is constant at 100 W/m2 during 10 hours or 60 10-min periods, the daily irradiation is 100x60/6=1 kWh/m2 again, as expected.
The monthly-mean value is obtained as an average of all daily values.
The problem here is when there are gaps in the experimental data time series. For details on how to resolve this correctly, see

Hi
You can find attached file regarding how to calculate the solar radiation.
The average daily solar insolation in units of kWh/m2 per day is sometimes referred to as "peak sun hours". if a given location receives a total of 6,650 Wh/m² of solar radiation over the course of a day, then that location gets 6.65 peak sun hours(1KW/m2). So you just need to simply calculate the total solar irradiance value to gain the result of peak sun hours in these 10 hours per day. Like you said if the measuring time interval is 10mins: R1*1/6+R2*1/6+R3*1/6...........R60*1/6=M daily total solar solutions
(R is your measured experimental solar irradiance data).
Same way for monthly.

is terrific. It is an estimation, as emphasised. Calculating the actual exposure for an individual is so much harder! Is that actually even required?- Badges
