L'energia procedent del Sol ha guanyat valor els \u00faltims anys com alternativa neta i respectuosa amb el medi ambient davant les energies no renovables, cares i molt contaminents<\/h2>\n\n\n\n

En aquest camp existeixen principalment dos tecnologies distintes que, depenen del Sol, per\u00f2 funcionen de forma molt diferent. Es tracta de l'energia solar fotovoltaica i l'energia solar t\u00e8rmica de les quals explicarem ara les seves difer\u00e8ncies.<\/p>\n\n\n\n

Qu\u00e8 agafen del Sol?<\/h3>\n\n\n\n

Encara que ambdues energies ens ajudaran a reduir la tarifa del nostre contracte de la llum<\/a> i es generen gr\u00e0cies als raigs solars, capten diferents propietats d'aquest.<\/p>\n\n\n\n

L'energia solar t\u00e8rmica s'aprofita de la calor que genera l'astre mentres que la fotovoltaica s'aprofita de la seva llum (la radiaci\u00f3). Ambdues ho fan gr\u00e0cies a panells, encara qye s\u00f3n diferents uns dels altres en funci\u00f3 de quin dels dos tipus d'energia vagi a produir.<\/p>\n\n\n\n

M\u00e8tode d'emmagatzematge<\/h3>\n\n\n\n

Altres de les principals diferencies entre ambdues \u00e9s la forma en que s'emmagatzemen els raigs captats, en cas de voler-ho fer. L'energia solar fotovoltaica ho fa mitjan\u00e7ant beteries mentre que la t\u00e8rmica ho fa en dip\u00f2sits d'aigua.<\/p>\n\n\n\n

\"la<\/figure><\/div>\n\n\n\n

Diferents usos<\/h3>\n\n\n\n

B\u00e0sicament, la t\u00e8rmica, com el que atrapa \u00e9s la calor, s'utilitza per calentar fluids que a la vegada serveixen per la producci\u00f3 d'aigua calenta sanit\u00e0ria i per la climatitzaci\u00f3 d'edificis i cases. D'aquesta forma obtenim una calefacci\u00f3 molt m\u00e9s sostenible que la tradicional de gas prop\u00e0<\/a>.<\/p>\n\n\n\n

L'energia fotovoltaica, per la seva part, \u00e9s la m\u00e9s coneguda per la seva possibilitat d'utilitzar-se per l'autoconsum el\u00e8ctric a l'alimentar motors i aparells el\u00e8ctrics.<\/p>\n\n\n\n

En definitiva, l'energia solar t\u00e8rmica absorveix l'energia solar per transformar-la en calor i l'energia solar fotovoltaica l'utilitza per transformar-la en electricitat. No obstant, la t\u00e8rmica tamb\u00e9 \u00e9s capa\u00e7 de generar electricitat com la fotovoltaica per\u00f2 no de manera directa com aquesta sino gr\u00e0cies al seu emmagatzematge.<\/p>\n\n\n\n

Difer\u00e8ncia de preu<\/h3>\n\n\n\n

No podem ignorar que la instal\u00b7laci\u00f3 dels panells solars \u00e9s cara, encara que a llarg termini compensa. Entre ambdos sistemes d'energia solar hi ha poca difer\u00e8ncia de preu, per\u00f2 la fotovoltaica sol ser una mica m\u00e9s assequible que la t\u00e8rmica.<\/p>\n\n\n\n

Avantatges de l'autoconsum<\/h3>\n\n\n\n

Els dos tipus d'energia permeten als usuaris abastir de l'energia solar, que \u00e9s gratu\u00efta, neta i renovable. A m\u00e9s, suposen un estalvi<\/a> a les factures de la llum o el gas ja que l'energia utilitzada a la casa, edifici o empresa a la que s'utilitzi \u00e9s la que es genera al propi lloc gr\u00e0cies als m\u00f2duls i no les que proporcionen les companyies el\u00e8ctriques.<\/p>\n\n\n\n

A m\u00e9s, ja siguin fotovoltaiques o t\u00e8rmiques, la instal\u00b7laci\u00f3 de panells \u00e9s una inversi\u00f3 a llarg termini ja que la seva amortitzaci\u00f3 acotuma a arribar entre 7 i 10 anys. Com es tracta d'elements pensats per a llarga durada, solen incluir \u00e0mplies garanties i la seva senzillesa tecnol\u00f2gica evita que requereixin un gran manteniment, pel que s\u00f3n molt pr\u00e0ctiques en aquest sentit.<\/p>","protected":false},"excerpt":{"rendered":"
