Solar panel price in Bangladesh
The modules are the main components of photovoltaic installations, in addition to producing energy for more than 25 years, they must withstand the most severe atmospheric variations. The price of a solar panel in Bangladesh ranges from TK 540 to over TK 5 lakh, and it depends on how much the total energy produced by solar panels is and how much you are going to use it.
What is a solar panel system?
Solar technology converts sunlight into electrical energy through photovoltaic (PV) panels or solar radiation-condensing mirrors. This energy can be used to generate electricity or stored in batteries or thermal storage.
How do solar panels work?
When the sun shines on a solar panel, the energy from the sunlight is absorbed by the photovoltaic cells of the panel. This energy creates electrical charges that move in response to the cell's internal electric field, causing electricity to flow.
How much power is required for solar panels? There are different capacities and sizes of solar panels that you can buy according to your needs. But the problem is when we don't know how much we require, let's not do a simple calculation. Suppose a person lights two lights and a fan with solar panels. Both lights are 10–20 watts and the fan is 20 watts, the total requirement is 40 watts. If we want to run for 6 hours per day, the total requirement is 40 × 6 = 240 watts. A lead acid battery in a solar panel requires a charging current of 240/12 = 20 amps or 10% of a 12-volt battery. So the charging current of a 20 amp battery will be 20 × 10/100 = 2 amps and a 2 amp solar panel will produce 2 amps of current. So if this person installs a 24-watt solar panel, they will be able to meet their electricity needs. So you can buy solar panels according to your needs.
How do I calculate the output of a solar panel?
Because every solar panel system is different, it is difficult to say exactly how much electricity it will produce. There are also some common benchmarks you can use to estimate your system's potential performance.
1. Solar panel output per day Calculate how much electricity your panels will produce per day, measured in kilowatt-hours (kWh), using this formula:
Size of a solar panel (in square meters) x 1000 That number x the efficiency of a solar panel (decimal in percent) This number x the number of hours of sunlight per day in your area Divide by 1000
Example Panel size 1.6 square meters: 1.6 × 1000 = 1600 The panel is 20% efficient: 1,600 × 0.2 = 320 Your area receives 4.5 hours of sunshine per day*: 320 × 4.5 = 1440 Divide by 1,000: 1440 ÷ 1000 = 1.44 kWh per day
*The number of hours of sunlight varies greatly throughout the year (4.5 hours is an estimate for July), and will be especially low during the winter months.
2. Solar panel output per month For a monthly total, calculate the daily figure, then multiply it by 30: 1.44 × 30 = 43.2 kWh per month.
3. Solar panel output per square meter The most popular home solar panel system is the 4 kW. It consists of 16 panels, each containing:
About 1.6 square meters (m2) in size Rated to produce approximately 265 watts (W) of power (under ideal conditions) To calculate production per square meter, use this formula: Number of panels x capacity of a solar panel system Power ÷ total system size (number of panels x size of a panel)
Example 16 panels of 265 watts each: 16 × 265 = 4240 kW power Total system size (16 panels of 1.6 m2 each): 4,240 ÷ 6 = 165 W per m2
What a panel is made of can affect its performance. 1. Monocrystalline panels use high-quality silicon, making them the most efficient in terms of manufacturing and space. 2. Polycrystalline panels are slightly less efficient but cheaper to buy.
