What are the key technological trends in Spanish home solar systems, and which emerging technologies

The technological development trends of Spanish home solar systems are mainly reflected in the following aspects:

Significant growth in photovoltaic installed capacity: It is pointed out that Spain plans to add 56GW photovoltaic systems by 2030, with a total of 76GW photovoltaic systems and 22GW energy storage systems installed. This shows that Spain's investment and application in photovoltaic technology are accelerating.



Development of solar thermal power generation: It is mentioned that Spain plans to add 5GW to the existing 2.3GW solar thermal power generation capacity, of which the first batch (2.5GW) is planned to be built from 2021 to 2025, and the second batch of 2.5GW will be built from 2026 to 2027. This shows Spain's technological progress and market expansion in the field of solar thermal power generation.

Wind and solar hybrid power generation projects: It is reported that Iberdrola has invested 40 million euros to build solar facilities and plans to improve its existing renewable energy assets in the next few years, including the development and construction of multiple wind-solar hybrid power generation projects. This shows that Spain is exploring a more efficient energy combination.

Application of user-side energy storage technology: It shows that the Spanish Photovoltaic Alliance and related companies have jointly carried out research work and won the first user-side energy storage record in Spain for the second consecutive year. The purpose is to determine the scale of user electricity consumption and propose solutions to meet the needs of the energy sector, especially solar energy, and renewable energy. This reflects the importance and application prospects of energy storage technology in home solar energy systems.

New technologies or improvements worth paying attention to in the next few years include:

• Continued growth and optimization of photovoltaic installed capacity
• Further development and application of solar thermal power generation technology
• Innovation and implementation of wind and solar hybrid power generation projects
• Popularization and optimization of user-side energy storage technology
