How to make the most of the excess from solar panels?

Photovoltaic solar energy involves the direct transformation of solar radiation into electricity using photovoltaic panels. Solar panels harness the energy from sunlight to generate electricity through the excitation of electrons in a semiconductor, creating a small potential difference. By connecting several panels in series, this potential difference can be increased, thus generating photovoltaic solar energy. But did you know that surpluses are generated from solar panels? There are ways to generate surpluses from solar panels to make the most of these surpluses. In this article, we share all our secrets about using photovoltaic energy.

The surplus self-consumption compensation is a mechanism that allows you to pay less on your electricity bill by taking advantage of the energy generated by solar panels that is not consumed. This surplus energy can be injected into the electrical grid and compensated on the electricity bill, helping to maximize the economic benefit of having solar panels.

What does it mean to have surpluses in self-consumption solar panels?

If you do not yet have solar panels and are considering their installation, it is important to understand this term. Photovoltaic solar energy is a sustainable and efficient way to generate electricity, harnessing solar radiation to meet your energy needs.

Surpluses from self-consumption solar panels are the energy produced by a self-consumption installation that is not used immediately and, therefore, is fed into the electrical grid. These surpluses usually occur at peak generation times, such as during the brightest hours in the case of photovoltaic installations, when electricity demand in the home is low or nonexistent. Instead of wasting this unused energy, it can be fed into the grid for later use. Self-consumption surpluses represent an opportunity to optimize the performance of renewable installations and maximize their contribution to energy self-sufficiency and carbon emission reduction.

How does surplus compensation from solar panels work?

Surplus self-consumption compensation is a process that offers owners of renewable energy generation installations, such as solar panels, the opportunity to economically benefit from the electricity they produce in excess and do not consume. This mechanism operates under two main modalities, each with its own characteristics and considerations.

• Agreement with the retailer for your surpluses: In this modality, the user reaches an agreement with the electricity company with which they have contracted their solar energy tariff. Both parties establish a price for each kWh of surplus energy that is fed into the electrical grid. This agreed price is deducted from the total electricity bill in each billing cycle. It is a simple and convenient option for those with regular and not very large surpluses, as it does not require complex procedures or the need to register as a producer.
• Sale of surpluses from your solar panels in the free market: In this option, the user must register as an energy producer and sell the surpluses directly in the electricity market. However, this alternative is usually not recommended for small or occasional surpluses in residential installations, as it involves more complex procedures and does not guarantee a significant economic return. This option is more reserved for producers with considerably large and regular surpluses.

Advantages of self-consumption with solar energy surpluses

Self-consumption with solar energy surpluses offers a series of economic and environmental benefits that are crucial for those who wish to maximize the use of solar energy generated in their installations. Below are some of the main advantages of self-consumption with surpluses:

1. Saving on the electricity bill: Using the energy generated by solar panels instead of grid electricity significantly reduces the cost on your electricity bill. Additionally, if you manage to compensate or sell the surplus energy, this savings can increase even more.
2. Profitability of the investment: Installing solar panels for self-consumption not only reduces long-term costs, but can also generate additional income through the compensation or sale of surpluses. This turns the initial investment into a profitable long-term option, as it pays off over time.
3. Contribution to the environment: By using a clean and renewable energy source, such as solar energy, dependence on fossil fuels is reduced and greenhouse gas emissions are decreased. This contributes to the fight against climate change and the conservation of the environment.
4. Energy independence: Generating your own energy reduces dependence on the conventional electrical grid, providing greater autonomy and energy security.
5. Promotion of self-sufficiency: Self-consumption with surpluses fosters a culture of energy self-sufficiency, where users take an active role in the production and management of their own energy. This promotes greater awareness of the responsible use of natural resources and the importance of renewable energy in a sustainable energy future.

Requirements for surplus solar energy compensation

To access surplus compensation within the framework of energy self-consumption, it is essential to meet a series of requirements established by the corresponding regulations. These requirements ensure the proper functioning of the system and protect the rights of both consumers and solar energy producers. Below are the main requirements to access surplus compensation:

1. Solar panel installation power not exceeding 100 kW: The regulations establish that self-consumption installations wishing to benefit from surplus compensation must not exceed a certain power, generally up to 100 kilowatts (kW). This limitation regulates the size of installations and ensures an equitable distribution of benefits.
2. Associated with self-consumption supply modalities: It is necessary for the installation to be associated with supply modalities that include self-consumption of energy generated from renewable sources, such as photovoltaic solar panels. This ensures that the energy produced is primarily intended for the user’s own consumption.
3. Ability to inject surplus energy into transport and distribution networks: To benefit from surplus compensation, the installation must have the technical capacity to inject surplus energy that was not consumed at the time of its generation into the transport and distribution networks. This implies having the necessary devices and systems to carry out this operation safely and efficiently.
4. Primary energy source must be renewable for the compensation agreement: If opting for a surplus compensation agreement with the retailer, it is essential that the primary energy source used in the installation is renewable, such as photovoltaic solar energy. This ensures that the energy generated and fed into the grid is clean and sustainable.
5. A surplus self-consumption compensation contract between consumer and producer is necessary: To formalize the surplus compensation process, it is necessary for the consumer and the solar energy producer to sign a specific contract that establishes the conditions and terms of the compensation. This contract defines aspects such as the price of surplus energy, the billing period, and other relevant details for both parties.

Meeting these requirements is essential to access and benefit from surplus compensation in the context of energy self-consumption, thus ensuring the proper functioning of the system and the optimal use of generated solar energy.

How to calculate the price of surplus solar energy generated by solar panels:

1. Offer from the retailer: First, obtain the offer from your electricity retailer. This offer will include the price per kilowatt hour (kWh) of solar energy that you feed into the electrical grid. This price may vary depending on the company and the conditions of the energy market.
2. Amount of surplus energy fed into the grid: Record the total amount of solar energy you have fed into the grid during the corresponding billing period. This information is obtained through a bidirectional meter that records both the energy consumed and the energy fed in.
3. Calculation of payment for surpluses: Multiply the price per kWh offered by your retailer by the total amount of surplus energy fed in. This will give you the total amount that the retailer will pay you for the solar energy surpluses.

This process allows you to accurately calculate how much the retailer will pay you for the solar energy surpluses generated by your solar panels and fed into the electrical grid. It is important to remember that the price per kWh may vary depending on the retail company and the conditions of the energy market at any given time.

What is the best option for paying for self-consumption surpluses?

The price of surpluses varies depending on the retailer, so it is advisable to make comparisons taking into account the cost of electricity.

What does the surplus compensation limit in solar energy self-consumption imply and how does it work?

The surplus compensation limit is a measure established within the regulatory framework of electrical energy self-consumption. Basically, this restriction is based on the premise that direct economic gains cannot be obtained through solar energy surpluses. Below, we explain how it works:

• Restriction on profits: The main purpose of the compensation limit is to prevent direct monetary benefits from being obtained from solar energy surpluses. This means that if you produce more energy than you consume during a billing period and that energy is fed into the electrical grid, you will not receive a cash payment for that surplus generated.
• Surpluses vs. Consumption: The compensation limit implies that if your energy surpluses exceed your electricity consumption in a specific billing period, you will not receive an economic refund for the difference between the two. Instead, that surplus will accumulate or be used to offset future consumption.
• Alternatives to avoid the limitation: One way to avoid this restriction is to choose to sell your energy surpluses in the free market instead of receiving direct compensation from your retailer. By registering as a producer and selling the generated energy, you are not subject to the compensation limit established for self-consumption users.

The surplus compensation limit from solar panels in self-consumption prevents receiving a direct payment for the surplus solar energy generated. However, you have the option to bypass this restriction by selling your surpluses in the free market, allowing you to generate economic income from the energy produced.

In conclusion, surplus compensation from solar panels provides you with a smart way to take advantage of the energy you generate but do not consume, helping you save on your electricity bill and contribute to environmental protection.
