The current from the parallel connected string (often called a "block") will then have a lower current than the remaining blocks in the module. This is electrically identical to the case of one shaded solar cell in series with several good cells, and the power from the entire block of solar cells is lost. The figure below shows this effect.
Wiring solar panels in parallel in 5 steps. Connecting solar panels in parallel means joining the positive (+) terminals of all the panels together and connecting the negative (-) terminals of all the panels together.
