Thank you for good links

can we storage this power for using in night?

Yes.It is possible. As I saw, It has been used in streets lights.

Dear Mohammad

when i click on the link it says there is no page!

Thanks Mohammad,i downloaded it, it's the good book

The formula to derate panels to your location is fairly straightforward. They are rated at their best output, but at a ridiculously high light intensity. You just need the average or possibly the yearly average worst day's light intensity from your local met data. You make a simple ratio of the measured intensity over the intensity used to rate the cell and multiply it with the rated output. This is a pretty solid installer estimate and should work for early hypotheticals. Although the units do get interesting as met data scientists and solar cell marketing departments do seem to use different measurements.

You just keep adding panels for a higher total power. If you are building your own hardware you get to design the panel architecture and current versus voltage configuration and deal with the problems. Adding in parallel gives more current and adding cells in a series ups the voltage. But nowadays you usually see weather safe sealed panel assemblies each with a dc/dc converter to match each panel to system voltage. Also a dc/dc sits between the system voltage buss and a battery voltage. buss. With these modular types you just keep adding more panels and 'standard' accessories like storage batteries, generators and inverters until you are satisfied.

Sorry for the wall I don't have any links just experience.

I hope it helps anyway,

Thanks Dear Mike for good Replying

If it is still actuall, I recomand you some very good and frealy acces PV energy project analysis software tools: http://re.jrc.ec.europa.eu/pvgis/ and http://www.retscreen.net/ang/home.php.

Agree with Mike Valliant

the power per "PV module" is not relevant as long as you can make an array of these devices - in this way it becomes fully scalable to your desired power output and there are plenty of interface electronics if you want specific voltages or currents.

You can generate the amount you want from PV systems if two things are available 1. The solar radiation potential ( i.e 4 kwh/m2/day is very acceptable). 2. The PV cells because the power generation from PV depends on the area of the PV systems installed.

There are many references and also there are some small software available in the net. But in general it depends on the efficiency of the PV cells used ( there are many types), The area of the PV cells, the Solar radiation.

Small research in Google u will find many references

Good Luck

To create an array to produce up to ...100 KW (Ptotal) is an easy task, Search for the produced power of a module, usually 200 ... 800W (PMod). Ptotal / PMod returns the number of needed modules. Those modules need the aera Atotal = n * AMod * sin(AlphaMod). Because the maximum power of a moduel will be produced, if the sun shines direkt (90°) on the module, the module has to be mountet in the angle AlphaMod. Thats it. To calculate the cost you need the price per Module * n. Also about 20 ... 30% of the Module Price has to be added for the needed power electronic and measurement to ease the maionanence of the array.

You can have a look at these simulation analysis for GCPV using MATLAB software:
