Solar Panel Roof Detail
34 solar energy panels (each panel is approximately 66” by 39” by 1.73”) totaling 608.3 square feet and located on three (3) roof areas in the rear of the house
The green and blue
outline of the solar
panels reflect the
two electrical
stringings required
for the optimizers.
This is the proposed solar panel located on the rear roof areas. Each solar panel is approximately 66” by 39” by 1.73”) totaling 608.3 square feet and located on three (3) roof areas
in the rear of the house primarily oriented southwest. The green and blue outline of the solar panels reflect the two electrical stringings required for the optimizers. Putting these
in the design helps long term in case the solar panel company has to troubleshoot an issue.
If repairs are needed, this allows the solar panel company to locate the
Similarities Between
Microinverters and Power Optimizers
Both microinverters and power optimizers carry out the same task within a solar panel system: they convert your direct current (DC) energy into the
alternate current (AC) energy that can be used in your home.
Both microinverters and power optimizers can monitor the performance of individual solar panels, rather than the solar panel
system as a whole.
Microinverters and power optimizers improve performance for solar panels on complicated roofs, or roofs that experience marginal shading during the day.
While microinverters
and power optimizers provide many of the same benefits, the two technologies also have many differences.
