Quick answer: A 3KW solar system of this configuration produces about 19.8KWH per day from 10x330W monocrystalline panels and driven by a 3KW/4.2KVA inverter. Built by Mars Solar (factory since 2008), CE/ROHS certified, 25-year panel life, shipped factory-direct to 130+ countries.
In May of this year, renewable energy provided more than 50% of Spain's electricity, and the Spanish government set a goal of achieving 74% of Solar Power At Home electricity from renewable energy by 2030.

While negotiating a "just transition" deal, the Spanish government has scrapped the so-called "solar tax" - which households with solar panels would have to pay extra to stay connected to the grid. This move has greatly promoted the development of the solar energy industry.
Asturias has not benefited as much as the sunny regions of Spain. Summers in the area are cool and foggy is common.
But investors see great potential for developing green hydrogen locally.
"We have electricity, we have water, we are close to the sea and ports, we produce hydrogen for direct export, and we have renewable energy not far from here," Rodriguez said. "So we think hydrogen is a good way to go. way."

The development of the wind energy industry is the key to Spain's transition from fossil energy to renewable energy. The country's current installed wind power capacity ranks second among European countries. Spain plans to double the country's installed wind power capacity over the next 10 years.
