Need Explanation about the DATA Simulation of 700Watts-BlueSun and 555watts JA Solar

[Rene]

Hi Good Day to everyone;

I need the answer about the below Project simulation, the Maximum Capacity of both are much the same 1MWp in the 1st Simulation I used 700Watts and the 2nd I used 555Watts but why is a big difference regarding the Production yield and the Performance ratio? hoping for your explanation thank you very much.

Hi Rene

without the project files it is hard to tell. Could you send me the project files here in the forum via private message so we can have a look?

Kind regards
Frederik

Hi Mr Frederik;

thank you for the response 

[Rene]

please see my private message thanks

Hi Rene

thank you for the project files.

A look into the energy balance shows unusual Low-light performance gains and Reflection losses:

Did you select a module from our database or did you put your own values? Be careful with parameters for the low-light performance.

Kind regards
Frederik

Hi, I selected PV Module in your database which is the 700W - Bluesun Solar Co. , so this means the module is wrong, thats why the performance ratio is too big ?

Hi Rene

yes, this is unfortunate. I forwarded this to our database team so the manufacturer can correct its values. Additionally we will check how to put closer checks for manufacturer input.

Meanwhile you could copy the module, uncheck, and re-check the Standard low-light performance setting to let PV*SOL calculate (estimated) reasonable values.

Kind regards

Hi Frederik;

    Thank you for my inquiry , also the 2nd thing is this we want to register our  solar modules in your Data base so that our own Modules are there, how can you do that in your part , also what is the requirement for registering our new panel in your data Base?

Hi Frederick , the database  Standard low-light performance setting cannot edit right? how can i copy or cannot 

 

[developer_fw]

Hi Rene

to put modules into the database and simulate with those you do not have to register. As far as I can tell from your website you do not produce your own modules but offer projects.

If you do have your own products, you can register an account via our manufacturer online database: https://pvsol-database.valentin-software.com/

By right-clicking you do open the context menu which offers to create a Copy. Official database entries are not mutable, copied entries (only visible to you) are.

Hi Frederick, how can i Register in the manufaturer database need an Log in account? thank you for your great response

Hi Frederik Good Morning, can you explain or differ the Spec. Annual Yield, the PV Generator Energy(AC Grid) , the Own Consumption , and Grid Export for this Result , many Thanks.

 

This is the settings that have a consumption.

 

This is the simulation settings with PV system Going to grid .

Hi Rene,

I am not sure if I understand your question. What differences do you want to have explained? The specific annual yield is the same in both cases.

Kind regards,

Martin

[Rene]

yes the differences, thanks

[developer_mh]

Hi Rene,

while I still do not really get the question and you did not explain your question any further, I'll try to give an answer to what I guess might be your question.

You have shown two tables with results of two systems. The PV production is the same in both cases (spec. annual yield, PR, PV generator energy (AC)). The difference is just that in one case you have consumers that use parts of the PV energy directly, while the other part is exported into the grid. So in this case you just have some additional results listed there.

Kind regards,

Martin

Hi Martin , one more thing how to change the dollars sign into Euro in the cash flow?, thanks in advance

Please have a look into our online help: https://help.valentin-software.com/pvsol/2023/en/start/system-requirements/#regional-settings-currency-numbers-time-and-date

You have to change the locale settings in windows and restart PV*SOL for the changes to appear.

Kind regards
