Do Solar Panels Need Direct Sunlight To Generate Power?

Solar Panel

Solar panels are a great and reliable substitute for non-renewable sources of energy. The photovoltaic cells present in a solar panel convert solar energy into electricity. This process of conversion is called the photovoltaic effect. Some elements are capable of releasing electrons by absorbing photons. The flow of electrons leads to the production of electricity. This highly effective technology is swiftly moving to the pinnacle in the market of energy supply.

In 2019, the installation of solar panels crossed 2 million, and it is anticipated that the number will double by 2023. The curiosity of customers regarding the effective functioning of solar panels is also on a spree nowadays. If you also ponder about questions like “do solar panels need direct sunlight to generate power?” Then your search ends here!

Performance of Solar Panels in Direct Sunlight

The efficiency of solar panels to produce light is highest in the presence of direct sunlight. However, this fact does not imply that solar panels aren’t worth keeping in the absence of direct sunlight. Because both the direct and indirect sunrays have photons, they can facilitate the emission of electrons, thus producing electricity. Moreover, to maintain the effectiveness of your panels, contact solar panel cleaning robot manufacturers to help you in your clean-up sessions.

At Which Time Do Solar Panels Generate Maximum Output?

To reach the peak output, the solar panels require 1000W/m2 of sunlight. The amount mentioned is available only in the presence of direct sunlight. The efficiency of power generation reaches its heights when the sun shines bright! On the other hand, when cloudy days or winter season set in, the solar panels produce electricity at a comparatively lower rate. A peak sun hour is defined as the amount of energy the panel receives in an entire day. And the average day consists of peak sun hours which provides around 4000watt/hour of power per day.

The durable silicon of photovoltaic cells has both positive and negative charges. It converts the received solar energy into electrical energy. The use of mirrors and reflectors in solar panels can help in increasing the number of photons. However, even after so many technological arrangements, the dust decreases the power output of photovoltaic cells. Therefore, solar panel cleaning robot manufacturersare highly important for the optimum performance of your cells.

Role of Battery Backup

Regardless of the weather, the photovoltaic cells of solar panels generate electricity every time. However, this isn’t true for nighttime. When the sun sets, there are no sun rays to provide photons. Thereby no electron emission takes place, and no power is generated during the night. Also, the solar panels can’t work up to their best if present in a too much-shaded region. Solar inverters can help you out to tackle such problems related to efficiency loss.

Types of Solar Inverters

There are mainly three types of inverters present in the market; all of them have different ways f dealing with efficiency loss due to shade.

String Inverters

String inverters are the most basic option among solar inverters. Here, we connect several panels in one inverter itself. The whole system works at the power of the weakest panel if one panel is shaded.

Micro-Inverters

In this system, every solar panel will have individual investors assigned for them. They have an inverter for each panel. If one of the panels is in the shade, the other will work with maximum efficiency.

Power Optimizers

They are the mix-up of string inverters and micro-inverters. Here, the single string converter receives direct current produced from panels. Both micro-inverters and power optimizers are more expensive than single string inverters. However, it would be worth investing if you had a solar panel in the shade.

Concluding Remark

The solar panels generate electricity at maximum efficiency in broad daylight. The effectiveness decreases when it is in the shade. You can go for solar inverters to overcome the issue. Also, dust and dirt can hamper the effectiveness of panels; therefore, consider contacting solar panel cleaning robot manufacturers.
