The demand for renewable energy sources has been increasing in Bangladesh due to the country’s high population density and limited natural resources. Solar energy is one of the most promising forms of renewable energy that can meet the country’s increasing energy demand. Solar panels, also known as photovoltaic (PV) panels, are an integral component of solar energy systems. In this article, we will discuss solar panel price in Bangladesh, features & technology, specification, types of solar panel.
Solar Panel Price in Bangladesh
The price of solar panels in Bangladesh varies depending on several factors, including the size, quality, and brand of the panel. On average, the price of a 250-watt solar panel in Bangladesh ranges from 6,000 to 8,000 BDT. However, the price can be higher for panels with higher wattage and better quality.
Features & Technology of Solar Panels
Solar panels are made up of photovoltaic cells that convert sunlight into electricity. The efficiency of a solar panel depends on the quality of the cells, the type of technology used, and the overall design of the panel. Some of the key features and technologies of solar panels are:
Monocrystalline vs. Polycrystalline Panels: Monocrystalline panels are made of single-crystal silicon and are more efficient but expensive. Polycrystalline panels are made of multiple silicon crystals and are less expensive but less efficient.
Efficiency: The efficiency of a solar panel refers to the amount of sunlight it can convert into electricity. Higher efficiency panels are more expensive but produce more electricity per square meter.
Durability: Solar panels should be durable enough to withstand harsh weather conditions and last for a long time. Most panels come with a warranty of 25 years or more.
Anti-Reflective Coating: Anti-reflective coating on solar panels helps to increase their efficiency by reducing the amount of sunlight that is reflected back.
Specification of Solar Panels
When buying solar panels, it’s important to understand the various specifications that determine the performance of the panel. Some of the key specifications are:
Wattage: The wattage of a solar panel determines how much electricity it can produce. Panels with higher wattage are more expensive but produce more electricity.
Voltage: The voltage of a solar panel determines how much electricity it can produce at a given time.
Amps: The amps of a solar panel determine how much current it can produce.
Temperature Coefficient: The temperature coefficient determines how efficiently a panel can convert sunlight into electricity at different temperatures.
Types of Solar Panels
There are several types of solar panels available in the market, each with its own advantages and disadvantages. Some of the most common types of solar panels are:
Monocrystalline Panels: These are made of single-crystal silicon and are more efficient but expensive.
Polycrystalline Panels: These are made of multiple silicon crystals and are less expensive but less efficient.
Thin-Film Panels: These are made of thin layers of photovoltaic material and are lightweight, flexible, and easy to install. However, they are less efficient than crystalline panels.
Concentrated PV Panels: These use lenses or mirrors to focus sunlight onto a small area of photovoltaic material, making them more efficient but expensive.
How much power do solar panels need?
The amount of power that solar panels need depends on several factors, including the size and number of panels, the amount of sunlight they receive, and the efficiency of the panels. Generally speaking, solar panels require enough sunlight to generate the necessary amount of electricity to power the appliances and devices in a home or business. The power output of a solar panel is measured in watts (W) or kilowatts (kW), and it can range from a few watts to several hundred watts per panel.
The typical residential solar panel system in the United States has a capacity of 5 to 20 kilowatts, which can generate between 6,000 and 24,000 kilowatt-hours of electricity per year, depending on the location and orientation of the panels. The amount of power that solar panels can generate also depends on the angle and direction of the panels in relation to the sun. Panels that are tilted at the optimal angle and direction to face the sun can generate more power than those that are not.
How do solar panels work?
Solar panels work by converting sunlight into electrical energy through a process called the photovoltaic effect. This process involves the use of photovoltaic (PV) cells, which are made up of layers of semiconductor materials, typically silicon.
When sunlight hits the surface of a solar panel, it is absorbed by the PV cells, causing the electrons in the semiconductor material to become excited and move around. This movement of electrons creates an electrical current, which is then captured by the wiring in the solar panel and sent to an inverter, which converts the DC (direct current) electricity into AC (alternating current) electricity that can be used to power appliances and devices.
The efficiency of a solar panel depends on several factors, including the quality of the PV cells, the design of the panel, and the amount of sunlight it receives. Some of the ways that manufacturers increase the efficiency of solar panels include using higher-quality PV cells, incorporating anti-reflective coatings to reduce the amount of sunlight that is lost, and designing the panel to capture as much sunlight as possible.
Solar energy has the potential to meet Bangladesh’s increasing energy demand while reducing its reliance on non-renewable sources of energy. The price of solar panels in Bangladesh varies depending on several factors, including the size, quality, and brand of the panel.
