About 300 watt solar panel

300 watt range of solar panels comes in 24 Volt and it is a cost-effective way for electricity generation in both the residential and industrial sectors. These panels are used to power a smaller to large size load. Solar installations on homes or businesses use 300 watt and above wattage solar panel. Before buying, it is important to understand what types, technology and parameters of a 300w panel.

This single 300 watt panel is capable of powering small loads up to 150 watt load with a single battery inverter like Gamma+ 12 Volt 1000VA solar inverter, 24V Solar Panel. You can connect up to 3 panels on 1kvA Gamma+ Solar Inverter as per your load or requirement. An important metric to consider when comparing solar panel options is the power rating of a panel, called wattage. A 300 watt is close to the average wattage of a solar panel available today and is suitable for many types of solar projects.

How Does A 300 Watt Solar Panel Work?

A 300 watt solar panel consists of many small solar cells around 60 to 72 cells. When sunlight hits these solar cells, they absorb that light and convert it into DC electricity. There is a positive layer and a negative layer in a solar panel,  which creates an electric field. This current is collected by the solar panels and sent to the solar inverter subsequently which converts it into alternative current or AC form.

Types of 300 watt solar panel

The 300-watt solar panel is a high efficiency solar panel that is available in three different types. These types are:

Monocrystalline Solar Panel

Monocrystalline solar cells
Monocrystalline solar cells

Mono-crystalline, also known as single crystalline silicon panel, is easily recognizable due to their outer dark black color. This solar panel is made by melting highly pure silicon. These panels are 19%  efficient.

Polycrystalline Solar Panel

Polycrystalline solar cell
Polycrystalline solar cell

Poly-crystalline is also known as multi-crystalline solar panel and unlike mono-crystalline solar panel molten silicon is poured into a square mold for their manufacture. Silicon of relatively low purity is used in these solar panels.

Bifacial Solar Panel

Bifacial solar cell

The bifacial solar panel is the latest technology solar panel. These panels can absorb sunlight from both the front and rear side, which increases their generation efficiency. Due to their high efficiency, they are relatively more expensive than other types of solar panels.

How many solar panels are required in a solar system?

It’s often seen that people want to install solar system, but they don’t have any idea of ​​how many solar panels they will have to install to meet the electricity needs of their house.

But now you have no need to worry. You can find out the quantity of solar panels according to the capacity of the solar system from the table given below.

Application for 300W Panel

A 300 watt solar panel alone can handles smaller, but if it is connected in series then it can run a heavy load very easily. There are lots of applications in which 300 watt solar panels are used, but most common applications are mentioned below.

Solar Conversion Kit

If you have a single or double battery inverter at home. You can easily convert it into a solar system using these solar panels with a small solar device called a “solar charge controller”. These solar panels and a solar conversion kit will convert your existing home inverter into a hybrid inverter, allowing you to start using solar energy for regular day-to-day operations.

Solar Home Lighting System

You can use this panel with your 24 Volt home lighting system. Solar home lighting system is one of the best way to light up your home and power your small appliances using the sun’s energy. 300 watt solar panel is a pocket as well as an environment friendly solar solution for home lighting systems. 

Off Grid Solar System

Off-grid solar system is a battery based solar system that provides power backup during power outages and nights. This system allows storing excess solar power into the solar battery that can be used later as required. 

On Grid Solar System

An on-grid solar system works with the utility grid. In this system, surplus power, which is not consumed in the home, is automatically exported to the electricity grid via a bi-directional meter which results in reduction of power bills. 

Hybrid Solar System

Hybrid solar system is a combo of on grid and off grid solar system. The electricity generated by the solar panel is first used to power the home. If the home’s electrical need is over, the access electricity will begin to be stored in the solar battery. After the battery is full, the rest of the electricity will be exported to the grid automatically.

Solar Water Pump

Solar water pump has emerged as a modern technology of farming. These pumps lift the water from various surfaces using electricity generated by solar panels. This pump is being used in the agriculture sector as well as now in residential sectors for drinking water, fountains etc.

Solar Air Conditioner

A solar air conditioner is powered by solar energy rather than grid electricity. It reduces both your energy bill as well as your carbon footprint. These are modern technology solar air conditioners that can either be powered by solar power, a solar battery, or the power grid.

Complete 300W Solar Panel System

A complete 300 watt solar system is a small, portable and compact solar system that is ready to power your small household devices at all times. After connecting the solar panel with the solar battery, you can use it to power a variety of electrical appliances such as fans, TVs, LED lights, and so on.
