In June 2018, the European Union reached an agreement that 32% of the energy consumed in 2030 will come from renewable sources . In Spain, the National Plan for Adaptation to Climate Change 2021-2030 (PNACC) has recently been approved, in addition to the already initiated measures of the National Integrated Energy and Climate Plan (PNIEC) where renewable energies for electricity generation in 2030 will reach 74% and renewable energies will increase to 42% in the final use of energy.
Choosing the best photovoltaic system , what does it depend on?
There are different types of solar modules on the market, with different structures, working methods and prices. High-efficiency monocrystalline modules, for example, are currently the most in demand, because they achieve greater power in the same available space on the roof, façade or pergola. If the module size is also sufficiently small, the mounting possibilities increase.
All-black designs allow for ideal architectural integration in buildings requiring maximum production, with a reduced visual impact on the architecture of the buildings.
In addition, modules with split-cell PERC technology, polycrystalline HCC, also allow the solar installation to have the lowest losses in the event of slight shading. The current trend is to choose increasingly efficient technologies and systems that are easier to assemble, have less maintenance and are more durable.
The most common installations are those for instant self-consumption, meaning that the production and consumption of electricity occur as simultaneously as possible, during daylight hours. This avoids the installation of batteries , which usually increases initial budgets, although from an energy perspective they are a solution for the future.
In conclusion, solar photovoltaic systems are an economically profitable reality, easy to install even in renovations, which together with highly efficient air conditioning systems represent savings for the consumer and a benefit for the environment.
