Working of a 100W Solar Panel

A single 100w solar panel comprises a cluster of solar photovoltaic cells manufactured from silicon – a semi-conductive material. When the sunlight falls on the panel’s surface, its energy or photons interact with silicon and set electrons in motion in the solar cell. An electric field created by positively and negatively charged semiconductors on the panel directs these electrons to flow towards the conductive metal plates. This creates an energy current in DC form. 

The DC current passes through a series of wires through the solar inverter, which converts the current into AC electricity. AC energy is used to run appliances and electronics. A 100w 12v solar panel can be tied to a local grid or used as an independent power source in remote locations.

100-Watt Solar Panel Price and Specification

The 100w solar panel price is a major consideration when getting solar for domestic or commercial use. As a lower-wattage option, this solar panel capacity is ideal for consumers looking for budget-friendly solar components.

When considering 100-watt 12-volt solar panels, you have three options to choose from monocrystalline, polycrystalline, and bifacial solar panels. 

Each solar panel type is unique in terms of cost, solar energy generation capacity, durability, efficiency rating, and more.

Monocrystalline solar panels are high-efficiency solar panels with a 15-20% rating. This means more kilowatt per hour output is generated for each square foot area covered. Mono panels can generate power even on cloudy or weak sunlight days. They are slightly more durable than poly panels but have a higher price tag.

Polycrystalline solar panels are less efficient than solar panels with a 13-16% rating. They are the least expensive option to generate clean solar power. During peak sun hours, poly panels can give energy output to its maximum capacity. High-quality poly panels are as durable as mono panels, though they deteriorate faster when exposed to high temperatures.

A bifacial solar panel is the best option for maximum energy generation in a limited space. A bifacial solar panel has solar cells on both sides, giving you nearly double the output you can get using traditional solar panels.

Below is a tabular representation of solar panel 100-watt prices in India. These are estimated price ranges for different solar panel types available on the market.

**The actual 100-watt 12-volt solar panel price in India may vary by 10% to 12% based on the location, number of panels needed, manufacturer, and other installation requirements.

The technical specifications of the 100-watt solar panel are as follows:

Disadvantages of 100-Watt Solar Panel

• Not 100% Reliable: Solar panels depend on sunlight to produce electricity. Therefore, the generation of power declines during winter months or on bad weather days.
• High Initial Cost: Although solar is a one-time investment, the initial cost is considerable. Most consumers can recover their initial solar 100-watt price within 6-8 years through reduced energy usage expenses. This payback period may vary depending on location, weather, and other factors.
• Problem of Efficiency: The efficiency rating of a solar panel is the biggest determinant of how much energy you can expect to receive across different seasons. Low efficiency means more panels are needed to generate the desired energy units. As you move up on the efficiency scale, per-panel cost also increases.
• Installation Area: Setting up a solar PV module requires space. If you have a very limited rooftop space that receives shade from neighbouring structures and trees, installing a 100-watt solar panel module can be challenging and costly.

Requirement of a 100-Watt 12-Volt Solar Panel to Fulfil Power Needs

Determining your power requirement is the first crucial step in selecting the panel wattage and the number of panels you need to generate the desired energy output. A 100-watt 12-volt solar panel is suitable for small-scale applications and doesn’t require a lot of space for installation unless you go for high-capacity systems.

Here is a rough estimation of the number of panels required to make up different system sizes.

Applications of a 100-Watt Solar Panel

A 100-watt solar panel can be used in a variety of ways, including:

• Charging day-to-day gadgets such as smartphones, smartwatches, laptops, and tablets
• For operating the cable box and watching TV
• For powering up the router to ensure internet connectivity
