Photovoltaic installation


Photovoltaic solar energy has become an increasingly popular solution for the generation of clean and renewable electricity. Photovoltaic panels are devices that convert solar energy into electricity, and can be installed in a single-family home to reduce its dependency on the conventional electrical grid. In this article, we'll explore the benefits of installing PV panels on a single-family home, and the key factors to consider before doing so.


Advantages of installing photovoltaic panels in a single-family house:


  1. Savings in electrical energy costs: One of the most obvious advantages of installing photovoltaic panels is the savings in electrical energy costs. By generating their own electricity from solar energy, homeowners can significantly reduce their electricity bills. Contribution to the environment: Another important advantage of solar energy is that it is a clean and renewable energy source. By using solar energy instead of fossil fuels to generate electricity, greenhouse gas emissions and other pollutants are reduced, which contributes to the environment. Energy independence: The installation of photovoltaic panels allows homeowners to become independent from the conventional power grid. This is particularly beneficial in remote areas where there is no access to grid power, or where grid power is unreliable or expensive. Property Valuation: Installing solar panels can increase a property's value. Home buyers are increasingly interested in homes that use renewable energy and respect the environment, so a house equipped with solar panels can be more attractive in the real estate market. Durability and low maintenance: Photovoltaic panels are very durable and require little maintenance. With a useful life of up to 25 years, homeowners can be sure that their panels will keep working for a long time.


Key factors to consider before installing photovoltaic panels:


  1. Location: The location of the home and the orientation of the panels are important factors to consider prior to installation. Solar panels work best when they face south and have no shadows covering them. Panel Size: Panel sizes should be adequate for the amount of electricity you want to generate. A solar panel installer can advise on the proper size of panels based on the energy consumption of the home. Installation Cost: The cost of installing solar panels can vary depending on the size of the installation and the complexity of the installation. same. Homeowners should carefully consider the cost of installation relative to long-term cost savings. Local Regulations: Local regulations may limit a homeowner's ability to install solar panels on their property.


Here are some very useful questions about a photovoltaic installation.

How many kWp do I need for a single family home?

Generally speaking, it is recommended that a solar installation for a single-family home with four people provide between 5 and 10 kWp. This range of power will cover the energy needs of the home and, in the best of cases, it will generate a surplus of energy that can be injected into the electrical network or stored in an optional battery. It is important to note that the size of the installation required can vary depending on geographic location, the orientation and tilt of the solar panels, as well as the energy consumption of the home. Therefore, it is advisable to request a personalized study to determine the specific energy needs of your home.

Does a solar installation without accumulator make sense?

The installation of solar panels without a solar energy accumulator can limit the use of the generated energy to a range of between 25 and 40%. However, if an accumulator is incorporated, the own energy consumption can increase up to 75%. Therefore, it is highly recommended to have a solar energy storage system in any photovoltaic installation to maximize its efficiency and profitability.

How much does a photovoltaic system without storage cost?

The estimated cost of a photovoltaic system without storage can range between 2,200 and 2,800 euros per kWp. It is important to keep in mind that these prices can vary according to different factors, so it is advisable to obtain a personalized quote. Likewise, it is possible to reduce these costs through subsidies and the fiscal optimization of the system, which can result in a more profitable and sustainable investment in the long term.

Why does self-generated electricity cost money?

Discharging the electricity generated in the electrical network does not provide any or very few advantages to the operator of the photovoltaic installation. For this reason, it is more convenient to consume self-generated electricity. In addition, the acquisition cost of a kilowatt hour (kWh) of electricity purchased in the electricity market is currently around 28 cents, while the kWh of self-generated electricity costs 5 cents. In this sense, having a photovoltaic system will allow you to save significantly on your electricity bill and, in turn, contribute to the environment, since the energy generated comes from renewable sources.

What regulations must my installation of solar panels respect?

Installations of self-consumption solar panels without surpluses must comply with the corresponding electrical safety regulations and technical regulations for their connection to the public network. Therefore, it is necessary to respect the rules indicated in the REBT regulation according to ITC-BT-40, as well as the general and specific requirements for energy measurement and management included in the metering point regulation.
