The way they work is very simple: photovoltaic cells capture photons from the sun and, thanks to the semiconductor material they are made of, silicon, they transform the photons into electrons.<\/p>\n<p>The current generated by the plates is direct current, so it has to be converted into alternating current via a solar inverter.&nbsp;<\/p>\n<p><\/p>\n<p><b>What factors influence the design of a photovoltaic installation?<\/b><\/p>\n<ul>\n<li><b>Orientation<\/b> and <b>inclination<\/b> of the solar panels: they have to be well directed towards the south and with an angle of inclination that optimises their photovoltaic production (35-40\u00ba depending on the site).<\/li>\n<li><b>Geographical<\/b> <b>location<\/b> of the city: the amount of sunshine hours your province receives will influence the energy production of the solar installation.<\/li>\n<li><b>Roof<\/b> <b>surface<\/b>: it is important to have enough space to carry out the installation. Each solar panel measures approximately 2 m2.<\/li>\n<\/ul>\n<p><\/p>\n<p><b>How many solar panels are needed for a house?<\/b><\/p>\n<p>The number of panels you need to install depends on your <b>annual<\/b> <b>consumption<\/b>. For a house that consumes between 5,000 and 8,000 kWh per year, between 6 and 8 solar panels will be necessary.&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><b>What do you know about aerothermal energy?&nbsp;<\/b><\/p>\n<p>What we can say to begin with is that aerothermal energy is a system that extracts the energy contained in the air to produce hot water, heating and cooling in homes. The principle of aerothermal energy is based on the <b>exchange<\/b> of <b>heat<\/b> from an <b>aerothermal<\/b> <b>pump<\/b> that uses the energy from the air to supply it to the interior of the home, thus consuming little electricity.<\/p>\n<p><\/p>\n<p><b>Advantages of aerothermal energy:<\/b><\/p>\n<ul>\n<li>Savings in the medium\/long term<\/li>\n<li>Greater safety because it does not use fuels<\/li>\n<li>High level of efficiency<\/li>\n<li>Allows heating and cooling with a single unit<\/li>\n<li>No maintenance required<\/li>\n<\/ul>\n<p><\/p>\n<p><b>What are the applications of aerothermal energy?<\/b><\/p>\n<ul>\n<li><b>Aerothermal<\/b> with <b>underfloor<\/b> <b>heating<\/b>: during the winter the water can reach 50\u00ba\/55\u00ba and can heat the floor. During the summer the water temperature can drop sufficiently to absorb the heat from the house.<\/li>\n<li><b>Aerothermal<\/b> with <b>radiators<\/b>: a system that transfers hot water to the radiators in the house.<\/li>\n<\/ul>\n<p><\/p>\n<p><b>Is it advisable to combine aerothermal energy with photovoltaic installations?<\/b><\/p>\n<p>These two resources, together, are a great example of autonomy in energy generation. On the one hand, aerothermal energy covers the thermal needs of a given space, and on the other hand, photovoltaic energy takes on the electrical costs required by the aerothermal pump. Nowadays, there is a trend that argues that aerothermal and photovoltaic are the perfect combination.<\/p>\n<p><\/p>\n<p>In Esp\u00edgul real estate we design your house following the indicated criteria that allow a maximum energy efficiency to make a rational use of energy, without forgetting the comfort in the interior spaces.
