Ma solar panels amagawidwa makamaka m'magulu A, B, C, mtundu wa A grade ndi wabwino kwambiri, B grade ndi wotsika pang'ono, sukugwirizana ndi miyezo ya A grade, koma ungagwiritsidwebe ntchito mu PV module ya zigawo za mphamvu ya dzuwa. Ubwino wa ma solar panels a B grade ndi wofooka pang'ono, monga ming'alu ina, kusiyana kwa mitundu, ndi zina zotero. Zolakwika izi zidzakhudza magwiridwe antchito ndi magwiridwe antchito ake.
Mitundu itatu iyi ya ma solar panel onse amapangidwa ndi maselo, galasi ndi back panel. Chifukwa cha kusiyana kwa mitundu, momwe amagwiritsidwira ntchito ndi osiyana.
Gulu lamagetsi la dzuwa la mtundu wa grade:imagwiritsidwa ntchito makamaka pa malo opangira magetsi pansi, malo opangira magetsi ogawidwa, makina apakhomo, ndi zina zotero, kwa zaka zoposa 25.
Gulu la solar la B grade:amagwiritsidwa ntchito makamaka mu nyali za pamsewu, makina opanda magetsi, magalimoto a batri, ndi zina zotero, ndipo amakhala ndi moyo wa zaka 5. Mtundu uwu wa chinthu ndi gawo lochepetsedwa la giredi A kapena lopangidwa ndi zinthu za giredi B.
Gulu la dzuwa la C Giredi:amagwiritsidwa ntchito kwambiri m'madera osatukuka, komwe ndi kusowa kwa magetsi, monga madera ena akutali, Middle East, South Africa, Afghanistan, ndi zina zotero. Ngakhale kuti nthawi yotsala ya moyo siidziwika. Chifukwa chake gulu lamagetsi la C Grade ndiye gulu losakhazikika kwambiri pakati pa atatuwa.
Ponena za mtengo, mapanelo a dzuwa a giredi B nthawi zambiri amakhala otsika mtengo kuposa a giredi A. Zipangizo zomwe zimagwiritsidwa ntchito komanso mtengo wa mapanelowo udzakhala wotsika mtengo kuposa a giredi A. Amalonda ambiri pofuna kuchepetsa ndalama zopangira, amakonda kugwiritsa ntchito maselo a giredi B kupanga, kupatsa makasitomala ma module otsika mtengo a photovoltaic.
Ponena za nthawi ya moyo, ngakhale kuti mapanelo a solar a B grade ali ndi khalidwe lotsika pang'ono kuposa mapanelo a A grade ndipo ali ndi zolakwika zina, sizimakhudza kuthekera kwake kopanga magetsi monga mwachizolowezi. Komabe, kugwiritsa ntchito bwino mapanelo a solar a B grade kuyenera kukhala kotsika kuposa kugwiritsa ntchito mapanelo a solar a A grade, chifukwa chake, nthawi ya moyo wa mapanelo a solar a B grade idzakhala yochepa kuposa ya A grade, zomwe zikutanthauzanso kuti nthawi ya ntchito ya mapanelo a solar a B grade ndi yayitali kuposa ya A grade.
Mwachidule, titha kuzindikira kuti kugwiritsa ntchito ma solar panels a B grade kungachepetse ndalama zopangira, kupatsa makasitomala mitengo yotsika mtengo, kulola makasitomala ambiri kulumikizana ndikugwiritsa ntchito ma solar panels, ndikupangitsa kuti kugwiritsa ntchito ma solar panels kukhale kozolowereka. Koma nthawi yomweyo, ma solar panels a B grade okha ali ndi zolakwika ndipo khalidwe lidzakhudzabe magwiridwe antchito ndi magwiridwe antchito pakugwiritsa ntchito, kotero polankhulana ndikugwirizana ndi makasitomala, tiyenera kufunsa zosowa zenizeni za makasitomala, kuphatikiza mtengo wopanga, kuti tiwonetsetse kuti kugwiritsa ntchito ma solar panels ndi mapulogalamu akwaniritsa miyezo yeniyeni ya makasitomala.
