Find out how to calculate the efficiency of the investment in solar panels for your home! Detailed guide to the esteem

The use of solar energy becomes an increasingly attractive option for many people. But how do you know if the investment in solar panels is really profitable for your home?

In this article, we will explore the steps you need to adopt to calculate the performance of the investment in solar panels, from the estimate of the initial costs to the evaluation of long -term economies.

Find out how to estimate the production of annual energy of the Solar System, what factors you should consider when calculating economies on energy invoices and how to establish the recovery period of your needs!

The costs associated with the purchase and installation of the Solar System

A photovoltaic system is an invention that brings renewable sun energy from the sun's rays directly to our homes and business. These innovative systems use photovoltaic panels Transform solar energy into electricity, offering a sustainable and ecological option to produce energy.

In order to determine the costs associated with the purchase and installation of the photovoltaic system, it is important to identify what it contains. Therefore, the main equipment that make up the system are:

It is important to remember that the entire investment for a photovoltaic system differs from one house to another. For example, for a key photovoltaic system with a power of about 35 kW, you will have to invest between 90,000 and 130,000 she.

Estimation of annual energy production

To obtain a precise estimate, it is important to consider Factors that influence the surrender of the solar panels.

The first important factor is Orientation of solar panels. This should be oriented to the south or south -est to maximize sun exposure during the day. A wrong orientation can reduce the production of solar energy. In addition, the angle of inclination of the solar panels can affect the production of energy, since too small or too high can reduce the surrender of the panels.

Another crucial factor is The geographical position of the house. The area in which you live can have a significant impact on energy production, since some regions benefit from greater exposure to the sun than others.

The quality of the solar panels It is another important aspect. High quality solar panels, which use efficient solar cells, will produce more energy than lower quality. It is recommended to invest in high quality solar panels to obtain a higher energy production.

It is important to mention that the production of solar energy can vary according to The size of the Solar System. The larger systems, with different solar panels, generally produce more energy than smaller systems. It is recommended to calculate the production of energy according to the size of the Solar System to obtain a precise estimate.

Calculation of savings on energy bills

The first stage in the calculation of savings is The analysis of the current energy consumption of the family. To do this, it is necessary to analyze the energy bills, identify the average monthly consumption and understand what the models of the consumer family are. This is an essential starting point for calculating how much you can save by moving on to solar energy.

Once discovered what the current energy consumption is, the next step is Estimation of energy production of the Solar System. This can be influenced by several factors, as I have already said in the ranks above. Using the specific data of solar panels and energy production estimates, it is possible to calculate how much energy will produce in a year.

After establishing the energy consumption and energy production of the Solar System, the next step is Cost comparison. This involves comparing the costs of ordinary energy invoices with energy production costs with the help of the Solar System. It is important to consider the costs associated with the maintenance and monitoring of the solar system.

Choose the recovery period of investments

It is necessary to establish a reasonable period in which to recover your investment in solar panels. To do this, it is important to understand the concept of Investment recovery period (PRI) and its importance in evaluating the profitability of an investment.

The period of recovery of the investment represents the time interval necessary for the savings obtained using the solar panels to compensate for the initial costs of the system. It is an essential indicator for determining whether an investment in solar panels is financially practicable.

The simple formula for calculating the investment recovery period is:

Pri = the initial cost of the monthly system / savings on energy bills

The initial cost of the sun system may vary according to the size and quality of the chosen system, as well as the costs associated with its installation. Savings on energy invoices depend on the energy consumption of the house and the sun level in the area. Maintenance costs may include control and replacement of the components of the Solar System. The life of the life of the solar panels can vary, but it is generally about 25-30 years.

As long as your home or business is correctly configured for solar panels and will receive a reasonable amount of sunlight during the day, you can enjoy you Advantages of solar panel systems.

How do you calculate investment performance in a sun system?

To calculate the performance of investments in solar panels that you can use ROI formula. Roi, or return to investments, is an important financial indicator that allows you to evaluate the efficiency of an investment and to compare different investments between them.

The formula for the calculation of investment performance (ROI) is as follows:

Roi = (net benefit / investment cost) * 100

Suppose we have the following data provided by a manufacturer or distributor of solar panels:

• The cost of investments in solar panels is 10,000 euros;
• The estimated economies on energy invoices are 1,200 euros per year.

By applying the ROI formula, we get:

Roi = (1,200 / 10,000) * 100 = 12%.

This means that investments in solar panels will generate a performance of 12% per year.

In conclusion, the installation of a solar panel system can be an excellent way to save money. The key is the right equipment, adequate planning and support.
