Collective self-consumption: 74 percent of Spain's apartment blocks are suitable for solar panels!

According to idealist/energy data, the vast majority of multi-familiar Spanish residential buildings can install solar panels on their roofs, which can lead to shared energy consumption among neighbours. Different sector studies have shown that bills can be cut by up to 40 percent and the initial investments can be paid off in about 7-10 years, while a photovoltaic installation will have a working life of at least 35 years. sales qatar

The government's commitment to the Urban Agenda 2030 with the abolition of the so-called sun tax and with the approval of Royal Decree 244/2019 of 5 April, which regulates self-consumption is a reality, the installation of clean and unpolluting energy sources to fight climate change and encourage household energy savings.

The self-consumption of electricity was the ideal solution for many homes and buildings in an effort to reduce housing costs or the cost of building (lift, lights, etc.). This is now being promoted to achieve collective self-consumption so that a number of consumers can be combined with the same power plant.

For example, several or all neighbors in one block could agree to share the costs and install solar panels on the building's roof to start consuming solar energy without having to disconnect them from the electricity grid.

The panels generate energy during sunshine hours. This renewable energy production is proportionally distributed to the contracted power. During those days of sunlight, all the energy your house needs will be self consuming energy and you will not spend a penny.

All excess power generated by the solar plant (panels on your roof), which are not required by your home, is transferred directly to the general network. The energy your home needs will be drawn from the general supply network at night.

Neighbors need to agree on the type of self-consumption they will share and set the criteria for the distribution of the energy produced. The installation depends on the square meters of each consumer's roof and needs. Clearly, the division of investment costs among several households helps to decrease the initial amount.

With most people working from home today, this is an option to take into account, as the biggest energy expenditure would take place in the daytime. Until now, if a family left home for work and school early, and came home late at night, the main consumption is consumed when the sun goes down and the overall supply chain is used.

The option of receiving compensation for the energy fed into the grid will depend on the type of self-consumption and installation conditions in the building.

According to data from idealista/energy, Spain's new main real estate project would allow 3 out of every 4 multi-family homes in Spain to install solar panels on their roofs and would benefit from the benefits of economizing in their homes on electricity.

Andalusia is the autonomous community with the most possible regions in Spain, with over 1,4 million buildings capable of installing solar panels on their roofs. Catalonia is followed by 730,000 blocks of apartments. Castile and León, and Castile La Mancha are virtually on an equal footing with 675 000 and 673 000 each, with more than 656 000 buildings near Valencia.

In Madrid, 322.000 buildings are appropriate among the large residential markets, while the numbers are behind the Canary and Balearic Islands, where single family homes are more common. There are about half a million suitable buildings in Galicia or 335,000 in Extremadura ahead of those regions. The following graph compares the number of multifamily buildings for installation in solar panels in each of the autonomous communities in Spain.

The complexity of the Spanish electricity system has complications, as users can use various forms of self-consumption with or without surpluses. Surplus energy can be injected into transmission and general distribution networks, but compensation is not eligible. If the solar plant were eligible for compensation, it would have to comply with the same rules as any power generation plant.

The Instituto para la Diversificación y Ahorro de la Energía, IDAE is developing a guide to process electricity generation systems for self-consumption of the type provided for in the Regulations both for individual self-consumption plants and for collective self-consumption plants. It is aimed at the general public, but in particular at companies that install self-consumption systems. There is currently a provisional version available.

"A surplus and compensation self-consumption approach is indeed feasible if you are a consumer associated with a nearby production facility via a network, but only if the generation plant is linked to an internal network of at least one consumer, which meets the requirements that are considered negligible for auxiliary manufacturing services, cl cl.

The main energy companies already have plans to install and manage solar panels for residential blocks such as EDP Energy for self-consumption. The planning and installation costs will depend on household usage and the building's common areas, but are organized according to whether consumption is low, from 40-70 euros a month to more than 100 euros per month and the electricity costs of more than 190 euros a month for the first 140 euros/ month for the Community.
