@seekingpeace1 Yes. Nagdedegrade ang output. Pero minimal lang. Magagamit sya for more than 20 or 30+ years. There are companies nga 25 years of warranty nung panel, pero very expensive pa rin sya as of now.
@timmccollum Make sure hindi nagkakaroon shading issue ang panels or nahaharangan sya like dusts or mga dahon dahon kung meron man. So yeah, ideal linisin from time to time if kaya naman gawin.
