50 Watt Solar Panel Price in India With subsidy, Benefits, Working

50 Watt solar panel

Are you looking for a small solar setup? A 50-watt solar panel is a small-sized photovoltaic module that can convert sunlight into electrical energy. It typically consists of 36 to 72 solar cells that are interconnected to produce a DC voltage output of around 12 to 24 volts.

The 50-watt solar panel can produce around 200 to 250 watts/hour of electricity every day, depending on the amount of sunlight it receives. The charge controller helps regulate the flow of energy between the solar panel and the battery to ensure that the battery is not overcharged or discharged. The battery stores the energy generated by the solar panel for later use.

A 50-watt solar system is ideal for small-scale applications in India, such as powering lights and fans in rural homes, or providing electricity for mobile charging stations and small businesses. It is also an excellent solution for off-grid locations where access to reliable grid electricity is limited. Among the many 50-watt solar panel uses, it can power small devices like camping lights, mobile chargers, and water pumps. It can also be used to charge batteries for off-grid applications, such as boats, RVs, and remote cabins.

Overall, it offers a range of benefits, making it a practical and efficient solution for small-scale solar projects and applications.

Working of a 50-watt Solar Panel

A 50-watt solar panel works by converting sunlight into electrical energy through the photovoltaic effect. The solar panel is made up of several solar cells that are connected in series or parallel.

Here’s how it works:

Sunlight hits the solar panel: When sunlight hits the solar panel, it is absorbed by the solar cells.

Photovoltaic effect: Solar cells are made up of semiconductor materials, usually silicon. When sunlight hits the semiconductor material, it knocks electrons loose from the atoms, creating a flow of electrical current.

Electrical current generation: The electrical current is then collected by the metal conductors on the top and bottom of the solar cells and transported to the wiring that connects the solar cells.

Conversion to usable electricity: The electrical current generated by the solar cells is direct current (DC) electricity. However, most appliances and electronics use alternating current (AC) electricity. To make the electricity usable, an inverter is required to convert the DC electricity to AC electricity.

Energy storage: If the panel is connected to a battery, the excess energy generated by the solar panel can be stored in the battery for later use. The battery stores the energy for use during times when there is little or no sunlight, such as during night hours.

50-Watt Solar Panel Price and Specification

A 50-watt monocrystalline solar panel uses high-quality, single-crystal silicon cells to convert sunlight into electricity. They are known for their high efficiency and sleek appearance and are often used in residential and commercial applications where space is limited.

A 50-watt polycrystalline solar panel uses multiple silicon cells to convert sunlight into electricity. They are made from silicon fragments that are melted together to form a square-shaped cell. They are known for their affordability and durability and are often used in residential and commercial applications where cost is a primary concern.

A 50-watt bifacial solar panel can generate electricity from both sides of the panel, as opposed to traditional solar panels that generate electricity from only one side. Both the rear and front sides of the panel carry solar cells that absorb sunlight and convert it into electricity, making them more efficient than traditional solar panels.

The solar 50-watt price and specifications can vary depending on the brand, quality, and type of panel. Here is an estimated range of prices and specifications for a 50-watt solar panel in India:

50-watt panel type Estimated price range
Monocrystalline panels ₹2300 to ₹2900
Polycrystalline panels ₹2400 to ₹3000

**The actual 50-watt solar panel price in India may vary by 10% to 12% depending on factors like location, number of panels used, manufacturer, and case-specific installation requirements.


Power output 50 watts
Voltage output 12 to 24 volts DC
Dimensions 540 mm x 670 mm x 30 mm
Weight 4 to 5 kg
Number of solar cells 36 to 72
Efficiency 15% to 18% or above
Operating temperature -40°C to +85°C
Warranty 5 to 25 years (depending on the brand)

It is important to note that the solar panel price 50-watt can vary greatly depending on the quality and brand of the panel. The polycrystalline solar panel price differs from the other panel types. It is recommended to research and compare different brands and suppliers to find the best option that meets your specific needs and budget.

Disadvantages of 50-watt Solar Panel

While there are many advantages to using a 50-watt solar panel, there are also a few disadvantages:

Limited Power Output: It has a relatively low power output, which may not be sufficient for powering larger devices or appliances. It is more suitable for small-scale applications, such as lighting and charging mobile devices.

Space Requirements: If you choose 50-watt solar panels to create a larger solar system setup, several panels would be required to generate the same amount of power as a high-capacity solar panel. As a result, you also require a higher square feet area to install your panels.

Weather Dependence: The amount of power generated by solar panels is highly dependent on weather conditions, such as sunlight and temperature. During cloudy or rainy days, the power output of standard panels may be significantly reduced.

Initial Cost: While a 50w solar panel price is more affordable than larger solar panels, the initial cost can still be a significant investment for households and businesses.

Installation Complexity: Although it is relatively easy to install, it still requires some technical knowledge and expertise. For those who do not have experience with solar installations, it may be necessary to hire a professional, adding to the overall cost.

Requirement of a 50-watt Solar Panel to Fulfil Power Needs

Your power use and the solar panel’s power generation capacity determine how many panels you would need.

The following are the main elements that affect a solar panel’s efficiency:

  • The specifications of various brands
  • The type of panel, such as monocrystalline or polycrystalline.

The standard formula for calculating the number of panels for any solar system size requires dividing the total system capacity by a single panel’s capacity.

Number of solar panels = Solar system capacity / solar panel capacity

Therefore, if you have decided to go with 50-watt solar panels, you can figure out the solar panel count for your system.

If you are looking to set up a basic 1kW (1000-watt) solar system using solar panels of 50-watt capacity, your system’s solar panel count is likely to be 20 panels. The calculation looks like 1000-watt / 50-watt = 20 panels.

Here are a few more calculations for your consideration:

Solar system capacity Estimated Energy Output

(per month)

No. of 50-watt solar panel needed
1 kW 120 units 20
2 kW 240 units 40
3 kW 360 units 60
5 kW 600 units 100
7.5 kW 900 units 150
10 kW 1200 units 200
