How do photovoltaic cells convert into electrical energy?

When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.

Do you know the historical origin of photovoltaic power generation?

In 1839, when a 19-year-old French Becquerel did a physical experiment, he found that when two metal electrodes in a conductive liquid were irradiated with light, the current would be strengthened, thus discovering the "photovoltaic effect";


In 1930, Lange first proposed to use the photovoltaic effect to make "solar cells" to turn solar energy into electricity;


In 1932, Audubote and Stola made the first "cadmium sulfide" solar cell;


In 1941, Orr discovered the photovoltaic effect on silicon; in May 1954, Bell Labs, Chapin, Fuller and Pearson in the United States issued a monocrystalline silicon solar cell with an efficiency of 6%, which was the first practical solar cell in the world. valuable solar cells. In the same year, Wicker first discovered that silver arsenide has photovoltaic effect and deposited cadmium sulfide film on glass to make solar cells. The practical photovoltaic power generation technology that converts sunlight energy into electric energy was born and developed.


The second satellite launched by the United States in 1958 was the first application of solar cells in space.


In 1960, solar cells were connected to the grid for the first time, marking the official entry of photovoltaic power generation into the grid, and it became an electrical energy that people can use every day.


In 1973, the University of Delaware built the world's first photovoltaic residence.


In 1984, commercial amorphous silicon solar cell modules came out.

Singfo Solar provides a complete set of household photovoltaic systems, including inverters, modules and energy storage batteries, all of which have passed TUV certification and are of safe and reliable quality.


What is distributed solar energy generation?

Distributed solar photovoltaics (PV) are systems that typically are sited on rooftops, but have less than 1 megawatt of capacity. This solution replaces conventional electricity-generating technologies such as coal, oil, and natural gas power plants.


Distributed solar energy generation refers to the use of solar energy by households, enterprises, public institutions, and other small-scale power generation systems.

These systems typically use solar panels to convert solar energy into electrical energy for self-use or sale to the grid. Distributed solar energy generation systems have the following characteristics:

1、Small scale: The system has a small scale compared to traditional power plants, typically generating only a few kilowatts to hundreds of kilowatts of electricity.

2、Decentralized: The system is typically located close to the load it supplies, often on the roof or facade of a building, which avoids the high distribution losses associated with traditional centralized power generation and transmission.

3、Highly flexible: Distributed solar energy generation systems can be installed and operational quickly, with little impact on the surrounding environment. They can also be expanded or reduced in size as needed.

4、Environmental friendliness: Solar energy is a clean and renewable energy source that does not emit greenhouse gases or other pollutants during operation.


Distributed solar energy generation systems are becoming increasingly popular as the cost of solar panels and other components continues to fall, and as countries and companies around the world strive to increase their use of renewable energy.

How do solar energy system work?

The sun is an incredible and renewable resource that has the power to fuel life on earth and provide clean, sustainable energy to all of its inhabitants.  In fact, more energy from the sun reaches our planet in one hour than is used by the entire population of the world in one year.  The sun’s energy can be converted into electricity through solar photovoltaic (PV) modules (photo = light, voltaic = electricity).

 

PV modules absorb sunlight and convert it into a usable form of electrical current. The overall process of a solar PV system is fairly simple and can be summarized in four steps.

 

1. The process begins when sunlight hits a solar panel, also known as a photovoltaic panel.

2. Solar cells within the panel absorb this energy and generate direct current (DC).

3. Wiring and circuits connected to the solar panels collect the DC power and convert it to alternating current (AC) through an inverter.

4. The AC power is then fed into your home's existing fuse box, distributing energy throughout your home to power all your devices. Additionally, any excess electricity not used can typically be sent to the grid (operated by a utility company) or used to charge batteries for backup power

 

The sun shines all over the world, making solar electricity viable anywhere. Because solar can be paired with batteries for energy storage, solar electric systems can be independent of the utility grid, making them cost-effective for remote locations. Solar modules have no moving parts making maintenance costs low, and they are highly reliable with a long service life of 25+ years of guaranteed electricity. Solar electricity relies on the sun as its fuel source, so there is no need to drill for petroleum-based fuels, refine them, or deliver them to the site. As you can see, there are a lot of advantages of solar energy.

 

Solar power systems offer a sustainable and efficient way to harness the sun’s energy. By understanding the components and processes involved in these systems, we can appreciate the technology that allows us to convert sunlight into electricity and heat. As technology advances and costs decrease, solar power is poised to play a crucial role in the future of energy production.


Is My Roof Suitable for Solar Panels?

In addition to estimating how many solar panels you need, consider the weight of the panels themselves. The average solar panel weighs around 40 pounds. It’s important to know what size solar system your roof can support, and remember, not all roofs can even support solar.


In addition to the weight, consider the material of your roof, how old it is, and whether it’s pitched or flat. All of these factors will help determine if your roof can support solar panels. It is also best to have a professional roof inspection before you decide to begin the installation process.

How much solar energy do I need?

Consider your annual electricity usage to determine how much electricity you need your solar panels to produce. You should be able to see your total energy consumption from the last twelve months on your electric bill.

How much energy does a solar panel generated?

Well it will depend on the average sunlight hours in your location

For example, For 550W solar panel, the average sunlight hour is 5 hour per day in my city,

So the calculation will be 550W*5*0.8 as coefficient=2.2kwh/day.

How many solar panel can be installed on your roof/place?

Considering the actual array and our installation experience,

For flat ground, C-type bracket, 1㎡ can be installed 130-150W.

shed frame bracket, 1㎡ can be installed 200-220W.

For Sloping roof, color-steel tile or glazed tile roof, 1㎡ can be installed 150-170W.

How to maintain solar panels?

Since there are no moving parts, solar panels require very little maintenance. Once you have covered the installation cost of solar panels, there are not much costs associated with maintaining them.


Having said that, you should inspect them a few times per year for dirt or some other things that might have piled on top. It is important that the panels are clean and there is nothing blocking them from efficiently absorbing the sun.


For a general cleaning, you can just use a normal garden hose to wash the face of the panels. You should do this in the morning or evening. Also avoid spraying them with cold water while they are hot because that might damage them.


Moreover, If the panels need some more cleaning that the hose cannot provide, you can use a sponge with soapy water to scrub them. You can also get the services of a cleaning company.
