Solar Panel Buying in Bangladesh
What is a Solar Panel System?
Solar panel can basically generate renewable electricity from direct sunlight. The electricity that we can use directly to run an electronics device or store it in a battery and use it later.
How does Solar Panel work?
The main component of a solar panel is the solar cell, which can generate electricity from sunlight. Another name for solar cell is photovoltaic. Note that photo means light and voltaic means electricity. Solar cells are usually made of a type of semiconductor metal such as germanium, silicon, carbon silicon carbide, etc. When solar cells made by these are exposed to sunlight, photovoltaic light energy absorbs photons from that light. As a result, some volts are generated there and when many such cells are combined, all of them together can generate much more volts and thus solar panel generate electricity through solar cells.
What are the advantage of using Solar Panel over other power source?
Renewable Energy Source: Solar panel uses renewable energy such as sunlight. This type of energy will not usually run out like non-renewable energy such as coal and gas. As a result, using solar panel you will not have any energy costs other than the one-time price of the solar panel and the set-up cost.
Save on Electricity Bill: Once you install this type of panel you will not have to worry about paying any energy bills like electricity bills.
Environmentally Friendly: Moreover, since solar panel uses an environmentally friendly energy source, they do not emit any greenhouse gases. As a result, it will not have any harmful effect on the environment around you or on climate change.
Independent Power Source: Also, when using solar panel, there is no need to depend on the electrical grid. As a result, you do not have to worry about load shedding or increasing utility rates. Therefore, solar panel are the best for you as an independent power source.
Flexible Installation: Solar panel can usually be set up on the roofs of home, office, or industrial area, in open space, and even in place unsuitable for agriculture. It will not have any adverse effect on the natural ecosystem. As a result, the biodiversity around you will remain normal.
Reduce Waste Generation: Other power sources generate a large amount of solid waste in the production and use of energy. This type of waste especially affects the medical and natural environment. On the other hand, much less waste is generated in the production and use of energy with solar panel. Moreover, this panel is made of silicon, glass, metal, and other materials so that most of the materials can be reused.
Access to Remote Area: In addition, electricity has not yet reached many rural areas in Bangladesh where there is no alternative to solar panel. Solar panel is the ideal solution for those remote villages.
What type of Solar Panel are available in Bangladesh?
- Monocrystalline Solar Panel: This type of solar panel is made of a single crystal structure. Monocrystalline solar panel have a high efficiency of 20-22%. Mono solar panel price is little bit higher but it provides maximum efficiency. In addition, this type of solar panel is quite smooth to look at. It lasts for about 25 years, so most manufacturers including Hamko, Sunshine, Rahim Afroz, and Longi provide long-term warranties on solar panel. In addition, monocrystalline solar panel can be used safely in both residential and commercial areas due to their resistance to environmental conditions and suitability for use in different climates.
- Polycrystalline Solar Panel: Polycrystalline solar panel is made of multiple silicon crystal structures. This type of solar panel is available at a lower price than monocrystalline solar panel. Its efficiency level is between 13-17% but provides good power output. It is suitable for budget-friendly users. Polycrystalline solar panel are quite effective in large buildings to save costs.
- Thin film Solar Panel: This type of solar panel is usually made of thin layers of copper indium gallium selenide (CIGS), cadmium telluride (CdTe), and organic photovoltaic materials. Due to this, it is quite light and flexible. It can be easily set up on the roofs and walls of houses, offices, or large buildings. Thin film solar panel is cheaper than monocrystalline solar panel and polycrystalline solar panel. Although the efficiency of thin film solar panel is between 10-13%, it works well in low light. As a result, thin film solar panel provide good power output in cloudy or low light environments.
Where can Solar Panel be used?
Solar panel can be used in various environments. Especially by setting up on the roofs of houses, and commercial establishments, daily electricity needs can be met. It is also used in large-scale solar farms, from which you can commercially supply renewable energy to thousands of home and business. Solar panel is an ideal power source to improve the quality of life outside the electrical grid or in remote rural or mountainous areas. Nowadays, portable solar systems can be used in modern devices and on engine-powered boats.
How much power does Solar Panel need?
There are solar panel of different capacities and sizes that you can purchase according to your needs. But the problem is when we don't know how much we need, then let's not do a simple calculation. Suppose a person runs two lights and a fan with a solar panel. Suppose the power of the two lights is 10 watts to 20 watts and the power of the fan is 20 watts then the total requirement is 40 watts. If we want to run for 6 hours every day, then the total requirement is 40 * 6 = 240 watts. This will require a battery of 240/12 = 20 amperes or 12 volts. The charging current of lead acid battery in solar panel is 10%. Then the charging current of 20 ampere battery will be 20 * 10/100 = 2 ampere and 2 ampere solar panel will be required to produce 2 ampere current. Therefore, if this person installs 24 watt solar panel, he will be able to meet his electricity demand. This way you can buy solar panel by calculating your needs.

Does the Bangladesh government give any incentives for using Solar Panel?
Bangladesh government provides various incentives for using solar panel. Especially subsidies for installing solar panel, tax exemption on solar panel parts, and low-interest loans for solar projects. In addition, there is a net metering policy due to which traders can sell excess energy to the grid. Such incentives have made the use of solar panel even more attractive.
Things to know before Solar Panel installation
- First of all, you need to check whether the solar panel receives sufficient sunlight and set it up in the right place. Because solar panel generate electricity from the light received through sunlight.
- If the solar panel is left in a shady place day after day, the efficiency of the panel will be lost in a few days.
- Sometimes, the solar panel can be damaged due to the use of high-ampere batteries in the solar panel. Because both the battery and the solar panel have to be set up according to a specific load. Otherwise, the solar panel will be damaged in a short time due to the excess load.
- Also, giving a load exceeding the specified capacity to the solar panel cannot perform well in the long term.
- In Bangladesh, especially during the rainy season, during storms, the solar panel gets clogged with leaves or dirt. If not cleaned properly during this time, the durability of the solar panel will gradually decrease and it will become unusable before the expiration date.
