A faulty inverter or charge controller are the most likely reasons for a solar panel to register no voltage. Other possible reasons for low to zero power are a damaged PV module, poor wiring, shading and temperature higher than the ideal operating range.
Barbados has reached the maximum capacity of the electric grid and the Barbados Light and Power Company has been advising that it is unable to connect homeowners and residential PV systems to the grid without the addition of storage.

Installing solar panels on the second floor is generally not recommended due to several key factors: 1) Structural integrity concerns, 2) Exposure to sunlight, 3) Efficiency and performance issues, 4) Cost-effectiveness evaluations.
PID is essentially a voltage leak. It happens when a difference in electrical potential between the solar cells and other panel materials, like the frame, causes ions to migrate. This can create a kind of "shadow" or dark patch on the panel.
The gap lines are spaces between the solar cells, through which you can see the panel's white backing. Both the fingers and the busbars are electrical conductors.
