4 FAQs about What kind of lights should be placed under the photovoltaic panels

What is a PV panel for a solar lighting system?

A PV panel for a solar lighting system differs from the traditional large solar panel, since it comprises four solar cells. PV panel consist of solar cells connected in series to produce a higher voltage. A single solar cell converts sunlight into electricity by generating current, which is called “photovoltaic effect”.

Should solar lights be placed in direct sunlight?

Ideally, solar lights should be placed in direct sunlight to function at their best. The solar panels use sunlight to produce electricity, so the more solar light they receive, the more energy they can generate. However, they still can function in the shade or during cloudy weather, but the efficiency of energy production will be reduced.

Can a solar light be installed on a roof?

A solar light provides you with maximum efficiency as long as solar panel cells receive enough sunlight every day. If a solar light is installed in a spot getting a low amount of sunlight, it is supposed to operate for a daily period shorter than recommended by the manufacturer. Solar lights are rarely installed on roofs.

Where should solar lights be mounted?

The place to mount the solar panels should be directly accessible by sunlight. This is also valid for indoor lighting systems, where longer cables are to be run between the PV panels (that should be mounted on the roof) and the remaining components. It is not necessary to mount the solar lights in a sunny place.
