# How much energy do solar panels create?

Next I will explain to you about How much energy do solar panels create?, a guide that explains in a simple and easy to understand way.

When referring to self-consumption, one of the most frequently asked questions is how many kWh a solar panel produces . The answer to this question depends on the price of the project and the space to carry out the installation.

## How much energy do solar panels create?

Knowing in depth how many kWh a plate can produce depends on the power and different factors that you must keep in mind. Panels have different numbers for their wattage, but you need to understand what they mean.

## How many kWh does a solar panel produce?

The answer to this question will depend on the panel since there are different powers. Another very important aspect that you must take into account is that over the years the power of the panels has been increasing. In turn, prices have been falling.

The power generated by solar panels is measured in watts (W) . There are different powers in the panels , you will find it indicated on the plate that you are looking at for its installation. The power between the solar panels ranges from 250W to 300W power . But it is true that it is currently common to see solar panels in homes with higher powers, such as 500W, there are also some with lower powers such as 150W.

In the event that you have a common panel of about 300W, this indicates that for every hour of sunshine the power that is generated is 300W. This leads to the following calculations, suppose it is a sunny spring day, in a warm area, the calculation would be:

300W x 5 hours of sunshine per day = 1500W or what is the same, 1.5 kWh per day.

To do the annual check, assume that these five hours are an annual average (compensating the hours of less sun in winter by those with more sun in summer), you will perform the following calculation:

1.5 kWh per day x 365 days of the year = 547 kWh per year for a 300W solar panel.

With these data you can make approximations, the consumption of kWh that an average home needs is about 8000kWh per year. This allows you to install with the size and panels you need to meet the needs of your home.

## The hours of sunshine and its impact on the kWh produced by a solar panel

In the previous example it is simple, calculating 5 hours of sunshine in a warm area, in the spring-summer season. but is it little for the cities in the south of the country?

What you need to consider when buying a panel and the first thing to look at is the wattage of 300W or 500W solar panels. These numbers refer to the power that the panels can provide you in optimal conditions.

But these conditions are not always or everywhere.

In this way, there may be 6,9, or 12 hours of sunshine in both northern and southern cities in summer, but very different hours of sunshine.

The incidence of the sun on the panels is greater in quality areas, so it is more likely that in these areas the panels reach the adequate power of 300W during the year. But in other cases it will be more difficult.

The new materials and innovations that are made in solar panels are achieving that even on days in which the weather conditions are not adequate, energy can be extracted, without reaching the maximum.

These are the three most important factors that you must take into account when knowing how much power a solar panel offers:

1. The wattage of the panel, this refers to the wattage of the board that you see in the catalog or on the label.

2. The hours of sunshine received by the place where the panel is going to be installed.

3. The incidence of sun in the place where the installation is carried out.

It is true that to use this tool you must have certain technical knowledge about photovoltaic energy.

Solar panels have a nominal generation power, which is reached in adequate conditions and must be guided by it.

But, it is true, that it may not always reach this power, that depends on the geographical area in which the installation is located. Therefore, you must take into account the three points that have been mentioned above. Without them, you cannot make a real calculation of the kWh that the panel of your installation can generate.

## What is the kWh power you should choose for your solar panel?

The answer to this question depends on:

– The budget you have.

– The energy consumption and how much you want to cover with solar energy.

– The amount of space you have to perform the installation.

Solar panels that have higher wattage are larger in size, but can take up less total space. The price of these panels is higher, although it may turn out that the set is cheaper than a greater number of plates with less power.

If you take into account all the tips in this post, you will be able to solve your doubts and know about kWh and panels of all kinds.
