Kamar yadda tushe kamar Hukumar Makamashi Mai Sabuntawa ta Duniya (IRENA) suka rubuta, farashin module na PV na hasken rana ya faɗi da fiye da 90% tsakanin 2010 da 2022. Samfurin da ya dogara da tsarin farashi kafin 2009 ya tsufa don kimanta riba na yanzu, ko da yake tsarinsa ya kasance mai inganci. Bugu da ƙari, yana ɗaukar tallafin 50% a matsayin abin da aka ba da shi, ba tare da tattauna dorewar kasafin kuɗinsa ko tasirin rikice-rikicen kasuwa na irin wannan babban shiga tsakani ba, batun da aka yi muhawara a cikin wallafe-wallafen tattalin arzikin makamashi.

Fahimta Mai Aiki

Ga masu tsara manufofin Slovakia a cikin 2009, wannan takarda ta kasance umarni bayyananne: ai da gabatar da farashin shigar da wutar lantarki (feed-in tariff) da sauri kuma a yi la'akari da kyaututtukan jari don fara sashen. Ga mai bincike na yau, darasin shine game da samfurin mai ƙarfi. Duk wani binciken tattalin arziki na fasaha mai saurin ci gaba kamar hasken rana dole ne a gwada shi da hankali akan raguwar farashin da ke sauri. Ya kamata a sabunta tsarin takardar tare da bayanan LCOE na yanzu daga BloombergNEF ko IRENA, wanda yanzu galibi yana nuna daidaiton grid na hasken rana a yawancin yankuna ba tare da buƙatar kyauta 50% ba. Makomar manufofin hasken rana na Slovakia ya kamata ta mai da hankali kan sauƙaƙe haɗin grid da binciken gwanjon gasa (kamar waɗanda aka yi amfani da su cikin nasara a Jamus da Portugal) maimakon dogaro da ƙayyadaddun, manyan tallafi, don tabbatar da faɗaɗa ƙarfi mai tsada.

7. Cikakkun Bayanai na Fasaha & Tsarin Lissafi

Babban kimantawar tattalin arziki ya dogara ne akan lissafin Farashin Wutar Lantarki da aka Daidaita (LCOE) da Ƙimar Yanzu ta Net (NPV). Duk da yake ba a bayyana dalla-dalla a cikin guntun ba, daidaitattun tsarin da suka dace da wannan binciken sune:

Farashin Wutar Lantarki da aka Daidaita (LCOE): Wannan ma'auni yana wakiltar farashin kowane raka'a (€/kWh) na gina da sarrafa masana'antar a tsawon rayuwarsa. $$LCOE = \frac{\sum_{t=1}^{n} \frac{I_t + M_t + F_t}{(1+r)^t}}{\sum_{t=1}^{n} \frac{E_t}{(1+r)^t}}$$ Ina:

  • $I_t$ = Kashe kuɗin saka hannun jari a shekara t (CapEx na farko, yada idan ya dace)
  • $M_t$ = Kashe kuɗin aiki da kulawa a shekara t
  • $F_t$ = Farashin man fetur (sifili ga PV)
  • $E_t$ = Samar da wutar lantarki a shekara t (kWh)
  • $r$ = Ƙimar rangwame
  • $n$ = Rayuwar tattalin arzikin tsarin (misali, shekaru 25)
Aikin yana da inganci idan LCOE dinsa ya fi ƙasa da farashin shigar da wutar lantarki (feed-in tariff) da aka garanti ko farashin kasuwa da ake tsammani.

Ƙimar Yanzu ta Net (NPV): Jimlar ƙimar yanzu na kuɗin shiga da fita. $$NPV = \sum_{t=0}^{n} \frac{R_t - C_t}{(1+r)^t}$$ Ina $R_t$ shine kuɗin shiga (Farashin shigar da wutar lantarki (Feed-in tariff) * $E_t$) kuma $C_t$ shine farashi a lokaci t. NPV mai kyau yana nuna saka hannun jari mai riba. Tallafin 50% zai rage ainihin $C_0$ (farashin saka hannun jari) kai tsaye, yana haɓaka NPV sosai.

Ribar Makamashi ta Shekara: $E_{annual} = P_{peak} \times G_{sol} \times PR$ Ina $P_{peak}$ shine ƙarfin kololuwa da aka saka (kWp), $G_{sol}$ shine ribar hasken rana ta musamman (kWh/kWp/shekara, wanda aka samo daga taswira), kuma $PR$ shine Ra'ayin Aiki (la'akari da asara, yawanci 0.75-0.85).

8. Tsarin Bincike: Misali Mai Amfani na Aiki

Yanayi: Kimanta masana'antar 720 kWp (Bambance-bambancen B) a wurin da ke da ribar hasken rana na 1250 kWh/kWp/shekara.

Zato (Misali):

  • Jimlar Farashin da aka Saka (CapEx): €1,200,000 (≈ €1,667/kWp, yana nuna farashin 2009).
  • Tallafi: Kyauta 50% → Farashin Mai Saka Hannun Jari na Net: €600,000.
  • Farashin Shigar da Wutar Lantarki (Feed-in Tariff): €0.45/kWh (an canza shi daga 14 SKK) na shekaru 12, sannan €0.08/kWh.
  • Farashin Aiki da Kulawa na Shekara (O&M): 1.5% na ainihin CapEx.
  • Ra'ayin Aiki (PR): 0.80.
  • Ƙimar Rangwame (r): 6%.
  • Rayuwa (n): shekaru 25.

Matakan Lissafi:

  1. Samarwa na Shekara: $E = 720 \text{ kWp} \times 1250 \text{ kWh/kWp} \times 0.80 = 720,000 \text{ kWh}$.
  2. Kwararar Kuɗin Shiga: Shekaru 1-12: $720,000 \times 0.45 = €324,000$. Shekaru 13-25: $720,000 \times 0.08 = €57,600$.
  3. Kwararar Farashi: Shekara 0: -€600,000. Shekaru 1-25: O&M = 1.5% na €1.2M = -€18,000/shekara.
  4. Lissafin NPV: Rangwamen kuɗin shiga na net na shekara (Kuɗin Shiga - O&M) zuwa Shekara 0 da cire ainihin farashin net. A cikin wannan sauƙaƙan misali, babban kuɗin shiga na shekaru 12 na farko zai yiwu ya haifar da NPV mai ƙarfi sosai ga yanayin tallafi, yayin da yanayin maras tallafi (farashin farko €1.2M) zai iya yin wahala don daidaitawa.
Wannan tsarin yana ba da damar yin bincike mai hankali akan mahimman masu canji: ribar hasken rana, ƙimar farashin shiga, ƙimar rangwame, da mafi mahimmanci, saurin raguwar sigar CapEx.

9. Ayyuka na Gaba & Hanyoyin Ci Gaba

Yanayin ya canza sosai tun wannan binciken na 2009. Hanyoyin gaba ga Slovakia da makamantansu na kasuwa sun haɗa da:

  • Bayyan Tallafi zuwa Hanyoyin Kasuwa: Canji daga ƙayyadaddun farashin shigar da wutar lantarki (feed-in tariffs) zuwa tsarin gwanjon gasa don PV mai girma, kamar yadda ake gani a yawancin EU, don gano ainihin farashin kasuwa da rage farashi.
  • Rarraba Samuwa & Masu Amfani (Prosumers): Mayar da hankali kan hasken rana na rufin gida don gidaje, kasuwanci, da gine-ginen masana'antu, wanda aka ba da damar ta hanyar ma'aunin net ko ƙayyadaddun farashin fitarwa, yana rage nauyin watsa grid.
  • Tsarin Haɗin Kai & Haɗin Ajiya: Haɗa masana'antun PV tare da tsarin ajiyar makamashi na baturi (BESS) don samar da wutar lantarki mai iya aikawa, daidaita grid, da kama mafi girman farashi yayin buƙatar kololuwa. Binciken tattalin arziki dole ne ya haɗa da CapEx na ajiya da kuɗin shiga daga ayyukan taimako.
  • Agrivoltaics: Haɗa shigar da allunan hasken rana tare da amfani da ƙasar noma, inganta yawan amfanin ƙasa kuma yuwuwar ƙirƙirar ƙarin hanyoyin kuɗin shiga ga manoma.
