With the change of climate, there are also many people who are curious about the so-called photovoltaic power generation. Is it possible to generate electricity only on sunny days? Wouldn't it not be able to generate electricity on rainy days?
Avvalo, biz fotovoltaik energiya ishlab chiqarish nima ekanligini bilishimiz kerak?
Photovoltaic, refers to the solar photovoltaic power generation system, is a kind of "photovoltaic effect" using semiconductor materials. When photons are irradiated on the surface of a metal or semiconductor, its energy can be completely absorbed by an electron in the metal or semiconductor, and the electron absorbs The energy is large enough to overcome the internal gravitational force of the object to do work and leave the original surface of the object to become photoelectrons. The current formed by the photoelectrons is called photocurrent.
Bulutli, yomg'irli, qorli, fotovoltaik elektr stantsiyalari hali ham elektr energiyasini ishlab chiqarishi mumkinmi?
In most people's cognition, photovoltaic power generation needs sunlight to generate electricity. Especially recently, it has been rainy everywhere. Many friends who have installed photovoltaics or want to install photovoltaics can't help but worry about whether the rainy weather will affect the impact. Photovoltaic power generation? Can it generate electricity if it snows in winter?
Ma'lumki, fotovoltaik energiya ishlab chiqarish energiya olsa-da, bu haqiqatan ham to'rt fasl, kun va tun, bulutli va quyoshli va boshqa meteorologik sharoitlar bilan bog'liq. Biroq, yomg'irli va qorli ob-havo sharoitida, to'g'ridan-to'g'ri quyosh nuri bo'lmasa-da, fotovoltaik elektr stantsiyalarining elektr energiyasini ishlab chiqarish nisbatan past bo'ladi, ammo bu elektr energiyasi ishlab chiqarish yo'qligini anglatmaydi. Fotovoltaik modullar kam yorug'lik sharoitida ham ma'lum darajada energiya ishlab chiqarishga erishishi mumkin. Yuqoridagi videodagi ma'lumotlar shuni ko'rsatadiki, 20 kilovattli fotoelektr stansiya yomg'irli kunlarda 20 kVt soat elektr energiyasi ishlab chiqaradi.
Ob-havo omillari bizning nazoratimizdan tashqarida bo'lsa-da, biz kundalik hayotimizda fotovoltaik modullarni saqlashda yaxshi ish qila olamiz. Modul o'rnatilgandan va elektr energiyasini ishlab chiqarishni boshlagandan so'ng, muntazam tekshirish va tozalash juda muhimdir. Muntazam tekshiruv elektr stantsiyasining ish holatidan xabardor bo'lishi mumkin. Muntazam tozalash modul yuzasidagi chang va boshqa kirlarni olib tashlashi va modulning energiya ishlab chiqarish samaradorligini oshirishi mumkin.
Uyingizda elektr stantsiyalarida quyosh panellarini tozalash bosqichlari
Tozalashdan oldin tozalanadigan panellarning ifloslanish darajasini tekshiring.
Engil ifloslanishda - zarrachalar yo'q, faqat chang, faqat yuvish yoki cho'tka bilan yuvish tavsiya etiladi.
Chuqur tozalash zarur bo'lganda, yuzada zarrachalar borligini aniqlasangiz yoki uning yo'qligiga ishonchingiz komil bo'lmasa, avval uni yuvib tashlang va zarrachalar yuvilgandan keyin cho'tka bilan tozalang. Nihoyat, uni yana toza suv bilan yuvish yaxshidir.
Modul yuzasida quruq suzuvchi kul, barglar va boshqalar kabi qo'shimchalarni tozalash uchun kichik quruq supurgi yoki lattadan foydalaning. Tuproq, qush axlati va oynaga yopishtirilgan yopishqoq narsalar kabi qattiq begona narsalar uchun biroz chizish uchun qattiqroq qirg'ichdan yoki dokadan foydalanish mumkin, ammo shuni ta'kidlash kerakki, qattiq materiallar shisha yuzasiga shikast etkazmaslik uchun chizish uchun ishlatilmaydi. Tozalash effektiga ko'ra, yuvish va tozalash kerak.
Yuving va tozalang. Qushlarning axlati, o'simlik shirasi va boshqalar qoldiqlari yoki oynaga chambarchas bog'langan nam tuproq kabi tozalab bo'lmaydigan narsalar uchun ularni tozalash kerak. Tozalash jarayoni odatda toza suv va olib tashlash uchun moslashuvchan cho'tkadan foydalanadi. Yog'li axloqsizlik va hokazolarga duch kelsangiz, ifloslangan joyni alohida tozalash uchun detarjan yoki sovunli suvdan foydalanishingiz mumkin.
