How much energy does a 100kw solar system produce?

Based on average solar radiation of 6 hours, a 100kW solar system can produce 100kW x 6 hours = 600kWh of electrical energy per day.

This is the optimal state, and is based on the calculation of the equator zone, the region with the most powerful solar radiation in the world.

Maybe you will be wondering. The sun rises at 5 am-6 am and there are about 12-13 hours of sunlight until sunset.

Why is it that in a 100kW solar system, only 6 hours of effective sunlight are taken?

A 100kW solar system can produce 100kW x 6 hours = 600kWh of electrical energy per day

This is not just calculated that way in a 100kw solar system but in all solar systems. Whether grid-connected or off-grid solar systems.

Because in the sky, sunlight is also combined with clouds. These clouds move with the air and block the sun’s radiation to the solar panels for a certain amount of time.

It is one of the reasons why generation power hours are different.

1-What determines the amount of power generated by a 100kW solar system?

From the solar panel’s point of view, it absorbs energy from the sun’s radiation, which produces electrons and outputs electricity.

Solar radiation is the radiant energy that reaches the earth’s surface from the sun. It intensity can be affected by factors such as latitude, weather conditions, time of day, and topography.

Under standard test (STC) conditions (am1.5, irradiance 1000W/m², 25°C), a photovoltaic panel per square meter can generate about 200W of electricity.

For example, the 100kW solar system design 169 x 580W solar panel, one panel measures 2.279m2 x 1.134m2 = 2.58m2 x 200W = 516.9W x 169pcs = 87.356kW, not enough 100kW.

In general, the higher the intensity of solar radiation, the more electricity the solar panel will generate (from STC data).

In areas with lower latitudes, more sunny days, and longer hours of sunshine, solar radiation intensity is higher, and solar panels generate more electricity.

Examples include the Middle East belt, and areas close to the equator.

Here are the regions and countries close to the equator to see if any are where you live:

Africa: Guinea, Congo, Central African Republic, Cameroon, Gabon, Eritrea, Somalia, Uganda, Kenya, Tanzania, Madagascar.

South America: Colombia, Ecuador, Peru, Brazil, Venezuela, Guyana, Suriname, French Guiana.

Asia: Indonesia, Malaysia, Singapore, Philippines, Thailand, Vietnam, Cambodia, Laos, Myanmar, Bangladesh, India, Sri Lanka.

Oceania: Papua New Guinea, Solomon Islands, Vanuatu, Fiji, Tonga, Samoa, Cook Islands, Tuvalu, Kiribati.

If you live or have an installation project in one of the above regions and countries, it is ideal to use a solar system.

This is because it allows the solar system to produce a full amount of electrical energy (meaning that a 580W photovoltaic panel produces a full amount of 580Wh or 600Wh of electrical energy).

But if you are not in the above countries and regions, there is no need to be frustrated. This is because 100kW solar systems do more than just include solar panels.

2-Importance of MPPT controllers for 100kW solar system

MPPT refers to Maximum Power Point Tracking, which functions to ensure that the solar panels always work at their maximum power point, thus increasing the power generation efficiency of the solar system.

Let’s take a 100kW solar system as an example. It contains:

169 x 580W solar panels (Adjustable according to actual electricity consumption, not a fixed qty)

3 x H8T PV combiner

3 x 100A MPPT controllers

In the case of a solar energy storage system, an AC inverter and batteries will be designed.

On the contrary, a grid-tied solar system has no batteries and only a grid-tied inverter (with a built-in MPPT controller).

If you are careful, you may have noticed that both energy storage and grid-tie designs include the MPPT controller as a configuration.

A grid-connected solar system converts DC power generated by photovoltaic panels into AC power that meets the grid requirements.

In a solar energy storage system, MPPT controller is the key player responsible for delivering solar energy to charge the batteries. Without it, energy transfer cannot be accomplished.

PVMars’ professional solar team can design a complete solar system according to your requirements to maximize power generation.

Among them, MPPT refers to Maximum Power Point Tracking, which functions to ensure that the solar panels always work at their maximum power point, thus increasing the power generation efficiency of the solar system.

Even if you are located in a place where solar radiation is relatively low, you can still maximize your performance with our MPPT controller.

Improve the efficiency of your home, factory, and appliances by generating more energy.

In addition, the angle of installation, cleaning, etc. Can improve the solar system’s power generation.

3- Factors affecting 100kW solar power generation

What's the difference between them? P and N types solar panel

On the market, the more mainstream solar panels are P and N-type panels, which use PERC and half-sheet technology.

It can effectively prevent the hot spot effect. Even if the solar panel is covered with bird droppings and leaves, it will not cause circuit occlusion and scorching.

In terms of power generation efficiency, N-type solar panels are currently more efficient than P-type panels, and the key lies in the production process that makes it so.

If you are interested in N-type solar panels, click on the orange font to jump to the relevant details.

In addition, solar panels should be cleaned once a month, and once a week in dusty areas. It will maximize the 100kW solar system’s power generation.

After choosing the right solar panels, the installation angle is also very influential.

Generally, solar panels are best oriented south. This is because the sun’s orbit around the Earth is elliptical.

For most of the year, the sun is above the equator.

Therefore, if the solar panels are oriented due south, the sun’s rays can strike the panels perpendicularly, resulting in maximum power generation.

If it is not possible to face due south, it is possible to face southeast or southwest, but the amount of power generated will be reduced.

Angle

The tilt angle of a solar panel is the angle of the solar panel to the ground plane. The optimal tilt angle for solar panels depends on local latitude.

In areas of lower latitude, the sun’s angle is higher, so the tilt angle of the solar panel can be appropriately adjusted. In areas of higher latitude, the sun’s angle is lower, so the tilt angle of the solar panel can be increased appropriately.

Generally speaking, it is optimal for the solar panel inclination angle to coincide with local latitude.

For example, if you are at 30° north latitude, it is advisable to control the solar panel bracket angle to be 30° as well.

Sum up

With a 100kW solar system, solar radiation energy is concentrated for 6 hours a day. The power generation for a year is estimated at 219,000kWh, which can meet the general electricity consumption of a commercial, industrial-type factory.

With other technologies, including smart trackers that follow the sun’s path, power generation can be increased by 40%.
