Danger level: High. The bulb''s intense heat can scorch or melt the socket and insulation on the fixture''s wires, which increases the risk of arcing — sparks that jump through the air from one wire to another. Arcing is a chief cause of electrical fires. The damage to socket and wires remains even after the bulb has been removed.
When deciding between high voltage and low voltage solar panels, keep in mind that higher voltage systems are more efficient in general for your off-grid solar power system. A 48V system is the most efficient and cost-effective per watt-hour generated as compared to 24V and 12V systems.

Call your power utility immediately to fix the problem. Somewhere downstream from the breaker, inside your house, an exposed hot wire is in contact with a ground wire or a conductor, such as a metal pipe-, and is leaking stray voltage to the ground. This leakage, known as a ground fault, is more pronounced when the ground is wet.
