    Default Math formula for calculation of solar power?

    Does anyone know if there are some mathematical formula for calculation of solar power? Or at least what parameters the electric energy depends on if produced by solar panel, like angle, days of sunny day, sunshine hour,latitude and longtitude,etc.?

    All that you mention plus cell temperature, actual insolation, panel orientation (in regards to due south), haze, clouds and the characteristics of a particular panel manufacturers models.

    I have seen no detailed calculation - only the results.

    Question

    Wondering calculation for both off-grid and grid-tie? Are they same or not??

    The losses are substantially higher for off grid due to the use of batteries.

    The panel output is identical.

    Thanks Russ.
    I am curious what is the algorithm behind the solar power calculator on the web.Does any one have a clue?

    No idea Cris - I would like to have a better idea as well.

    If you use insolation for a location and stated panel efficiency the numbers come way off from what people seem to get.

    Default Possible..

    All that I can tell you is that this is possible, and the reason you don't see it posted around the internet is because people are greedy. (I work for a company that specializes in this kind of research)

    That is not greed my friend. People spends years and millions of dollars developing their product and methods. They do not give it away. Besides if you look around here I have detailed it out at 1000 times.

    Half full or half empty in my opinion. I'm sure there are a hundred ways to do this.

    Oh! I see - a secret! A conspiracy! Those horrible people.

    You may be a janitor for a company doing that kind of research - or maybe a secretary but you apparently know nothing but green blather.

    We are not the kind of site that goes along with such trash talk.
