Standard module object builder¶
-
pvmismatch.pvmismatch_lib.pvmodule.standard_cellpos_pat(nrows, ncols_per_substr)¶ Standard module object builder.
Parameters: - nrows (integer) – Number of rows of cells in module.
- ncols_per_substr (list of integers) – Number of columns of cells in each substring (in parallel with a diode).
Returns: cellpos – Outermost list is a list of substrings in parallel with a bypass diode and in series with each other. The substring is a list of columns in that substring. Inside the column are the actual cells in each row. Each cell has a ‘crosstie’ key and an index.
Return type: list of lists
Cross-tied module object builder¶
-
pvmismatch.pvmismatch_lib.pvmodule.crosstied_cellpos_pat(nrows_per_substrs, ncols, partial=False)¶ Cross-tied module object builder.
Parameters: - nrows_per_substr (list of integers) – Number of rows of cells in each substring (in parallel with a diode).
- ncols (integer) – Number of columns of cells.
- partial (boolean) – False (default) means TCT (all cells are cross-tied). True means no cross-tiling.
Returns: cellpos – Outermost list is a list of substrings in parallel with a bypass diode and in series with each other. The substring is a list of columns in that substring. Inside the column are the actual cells in each row. Each cell has a ‘crosstie’ key and an index.
Return type: list of lists
Standard module object¶
-
pvmismatch.pvmismatch_lib.pvmodule.STD96¶ Standard module – 12x8 cells Substrings have 2, 4 and 2 columns of cells per diode
