"Boholo boo bo boholo ba tlhaho bo tsamaisa boits'oaro bona ba PID, haeba li-module kapa lisebelisoa tsa elektroniki tsa motlakase li sa etsoa ka tsela e itseng ho fokotsa sena," ho boletse Steven Marsh, motsamaisi e moholo oa theknoloji le moralo ho nts'etsopele e kholo ea Origis Energy.
Li-module tsa "thin-film" li kotsing ea PID ka lebaka la matla a tsona a phahameng a motlakase le litlolo tse entsoeng ka thepa, empa liphanele tsa silicon tsa kristale le tsona li kotsing. haeba ho na le mefokolo ea liphaphatha.Moqapi oa Silicon Ranch o etelletsa pele ts'ebetso ea anti-PID bakeng sa li-inverters tsa likhoele mefuteng ka bobeli ea merero.
"Li entsoe ka tsela e fapaneng, empa ke ntho e tšoananggkhathatseha hore moetsi oa letsatsi o tlameha ho ba le, e leng mefokolo ena e nyenyane holiphanele tsa letsatsi, u itebela khahlanong le likarolo tsa anti-PID ho hauli-inverters, "Ho boletse Nick de Vries, SVP ea theknoloji le tsamaiso ea thepa ea Silicon Ranch.
Ha theknoloji e ncha ea phanele e tsoa, hangata ho nka nako ho lokisa sehlahisoa ho fokotsa kotsi ea PID.Mehlala ea pele ea li-module tsa khalase ea khalase e ne e na le mathata le PID, empa bahlahisi ba hatetse pele ho tloha ka nako eo, ho boletse Marsh.
“[PID] e khutla nako le nako ha theknoloji e ntse e fetoha, hobane feela e le ncha ebile e ntse e tsoela pele.Ke boemo bo boima haholo boo li-module li tlamehang ho feta ho bona, ”o boletse joalo.
Li-inverters tse bohareng ke bethe e sireletsehileng ea ho qoba PID.Li kenyelletsa li-transformer tse hahelletsoeng tse thehiloeng hampe, tse arolang mahlakore a DC le AC a sistimi.
Empa ha li-inverters tsa likhoele tse se nang li-transformer li ntse li sebelisoa haholo mererong e meholo bakeng sa bonolo ba O&M, ka liphanele tsa lifilimi tse tšesaane le ho seng joalo, beng ba merero joale ba tlameha ho nahana ka phokotso ea PID.
"Ho na le litsela tse 'maloa tsa bohlokoa tseo u ka finyellang ho itšehla thajana ka tsona,' me transformer ke e 'ngoe ea tsona.Ho etsa hore phetoho e se ke ea fetoha ka bomalimabe ho baka bothata boo, ”ho boletse Marsh."Sehlopha sa PV se tla qetella se phaphametse, 'me hangata se boleloang ke hoo e ka bang halofo ea li-module tsamaisong eohle e tla ba le leeme le lebe ho ea fatše."
Ho ka sebelisoa mekhoa e 'maloa ho thusa ho qoba PID ho li-inverters tse se nang mohala.Li-installer li ka eketsa sesebelisoa sa ho itšehla thajana kapa sa theola transformer ea mohato ka lehlakoreng la AC.'Me bahlahisi ba se ba eketsa lisebelisoa le software e khethehileng ho li-inverters ho loantša PID.
Marsh o re ho na le mekhahlelo e 'meli ea phokotso ea PID ka khoeleli-inverters- Mekhoa e sebetsang ea anti-PID le mekhoa ea ho hlaphoheloa ea PID.Litharollo tse sebetsang tsa anti-PID le litharollo tsa software li nka lehlakore la DC la sistimi le ho phahamisa motlakase hore li-module tsohle li be ka holim'a lefatše.Ka lehlakoreng le leng, mekhoa ea ho hlaphoheloa ea PID e sebetsa bosiu ho etsolla PID e bokelletsoeng motšehare.Leha ho le joalo, moetsi oa lifilimi tse tšesaane tsa First Solar o re li-module tsa eona li arabela hamolemo ts'ebetsong e sebetsang ea anti-PID ho fapana le ho hlaphoheloa ha PID.
Baetsi ba li-inverter tse 'maloa' marakeng hona joale ba kenyelletsa lisebelisoa tsa anti-PID le software e tsamaeang le eona ho itšireletsa ho senyehe, kapa ho rekisa lisebelisoa tse arohaneng ho etsa mesebetsi ea ts'ireletso.Ka mohlala, CPS America e fana ka CPS Energy Balancer , ha Sungrow e haha li-anti-PID hardware ho li-inverters tsa likhoele tsa SG125HV le SG250HX.Sungrow o qalile ho fana ka li-inverters tsa likhoele tsa anti-PID ho pota 2018.
"Ho ne ho e-na le lipotso mabapi le litekanyetso tsa ho senyeha ha liphanele ka kakaretso ka nako eo, kahoo re ile ra hlahisa tharollo," ho boletse Daniel Friberg, mookameli oa lihlahisoa le boenjiniere Sungrow.
Yaskawa Solectria haufinyane e phatlalalitse mofuta oa anti-PID oa XGI 1500-250 letoto la likhoele tse etselitsoeng ho sebetsa le li-module tsa Filimi tse nyane tsa Solar.

Ka bobeli Solectria le First Solar li etsa lihlahisoa tsa tsona United States, li fa batho ba kenyang litlhophiso tse bonolo ho finyella lipakane tsa khothatso ea litaba tsa lehae tse kenyelelitsoeng ho IRA.Empa ba ile ba buisana ka phokotso ea PID hantle pele IRA e ngoloa.
"Re qalile kamano eo lilemong tse peli tse fetileng, ka sepheo sa boemo ba tekheniki ho fihlela sehlahisoa se lumellanang habonolo le sehlahisoa sa rona," ho boletse Alex Kamerer, mookameli oa morero ho First Solar."Re nka mohato o mong hape oa ho netefatsa hore re lumellana le bafani ba sistimi ea rona, e leng se thusang bareki ba rona."
Leha bahlahisi ba bangata ba li-inverter ba qala ho kenyelletsa mesebetsi e khahlanong le PID ho li-inverters tsa likhoele ha theknoloji e ntse e sebelisoa haholo mererong e meholoanyane, ka linako tse ling baenjiniere ba tlameha ho cheka maqephe a data ho lekola bokhoni ba sehlahisoa sa anti-PID, ho latela Origis's Marsh.
O ile a re: "Re fumana hore ho na le likhetho tse 'maloa moo,' me ha se hakaalo hore ke mokhanni e moholo oa litšenyehelo tsa pele tsa inverter.Leha ho le joalo, tsena ha li na tloaelo ea ho phatlalatsoa haholo ka likarolo tsa li-inverter, mohlomong hobane sehlooho se tekheniki haholo, kapa esita le [hobane] PID ka boeona e thata ho e lemoha tšimong.Kahoo ka sebele re bona li-inverter tse se nang li-transformer tse tlang ntle le mosebetsi ona. ”
Empa ho fokotsa PID ho tla ba bohlokoa le ho feta kaha lik'hamphani tsa letsatsi li se li na le khetho ea ho nka mokitlane oa lekhetho la tlhahiso (PTC) ho IRA.Ho boloka nyenyefatso e le hore li-module li hlahise matla a mangata ka nako e telele kamoo ho ka khonehang ho tla ba bohlokoa bakeng sa bonnete ba mokitlane oa lekhetho.
