Do You Need Direct Sunlight For Solar Panels To Work

Depending on where you live and the amount of sunlight you get throughout the year you may choose to either store your lights for some part of the year or strategically place them so that they receive the maximum amount of sunlight.

Do you need direct sunlight for solar panels to work. Heat isn t a factor in how much electricity pv solar panels can generate either so a cool spring day can be as productive if not more than a hot. One peak sun hour 1000 w m 2 of sunlight. The matter of fact is solar panels use daylight energy to produce electricity and they do not need direct sunlight to work. Amorphous panels will work best in shady or cloudy conditions but will not compete with monocrystalline or polycrystalline panels will when the sun comes out.

All solar panels will perform better in open south facing locations that get direct sunlight. However when calculating the total amount of peak sun hours received at any location you don t just consider hours with 1000 w m 2 of solar radiation. Well the reason is that the photons in natural daylight get converted into electricity by solar panels. Remember that solar lights work best in direct sunlight so cloudy weather can diminish how well they perform.

You then express that in terms of the equivalent number of hours with 1000 w m 2. Solar panels use daylight energy to generate electricity so panels do not need direct sunlight to work. Solar panels produce electricity from the photons present in natural daylight rather than from the sunlight itself so panels don t actually need to be installed in direct sunlight to work. A surprising answer isn t it.

Heat has no effect on the production of electricity. That means that just like on a cloudy day at the beach when you get a worse sunburn daylight is the source of solar energy. Do solar panels need direct sunlight to work. Solar panels use the energy from daylight not necessarily direct sunlight to produce the energy that they then convert into useable electricity.

Instead you need to add the total amount of solar irradiance received by the location.
