在自家屋頂裝個(gè)光伏發(fā)電設(shè)備，不僅可供自家用電，多余的電還可以賣給供電局，你想過嗎？惠州仲愷高新區(qū)惠環(huán)街道辦的一位居民就在自家屋頂裝了10千瓦的光伏發(fā)電設(shè)備，理論上每小時(shí)可發(fā)10度電，這是目前為止惠州裝機(jī)容量最大的家庭光伏發(fā)電。據(jù) 計(jì)算，平均每年能省1.8萬元左右，只要五六年的時(shí)間就可以收回9萬元的投資成本。

     5日上午，記者來到位于惠環(huán)街道辦洋里村的一棟居民自建房，這棟摟共有六層，房主李永龍今年在樓頂安裝了10千瓦的光伏發(fā)電設(shè)備，當(dāng)天，仲愷供電局 的工作人員也來到他家進(jìn)行中期驗(yàn)收，然后李永龍去供電局領(lǐng)回雙向計(jì)量電表安裝后，他家自己發(fā)的電就可以并入電網(wǎng)，多余的電就可以賣給供電局。 

      惠州市民樓頂裝太陽能光伏發(fā)電，在6樓樓頂，李永龍用鋼管搭起了一個(gè)2米多高的棚子，棚子上就覆蓋了太陽能硅板，總共有40塊，每塊1米寬，1.66米長，每塊硅板價(jià)格1000多元，加上其他材料費(fèi)，全部做好他花了將近9萬元，按裝機(jī)容量10千瓦算，成本每瓦9元左右。 目 前，光伏設(shè)備已經(jīng)裝好了10多天，已經(jīng)開始發(fā)電了，記者從墻壁上的三相光伏并網(wǎng)逆變器上看到，總共已經(jīng)發(fā)了853度電，5日當(dāng)天到早上9點(diǎn)多，也發(fā)了6度 多電。李永龍說，10千瓦理論上可以每小時(shí)發(fā)10度電，但受天氣情況影響，平均每小時(shí)只能發(fā)7度電左右，一天大約可以發(fā)10小時(shí)，一個(gè)月發(fā)2000度電左 右。這棟樓除了李永龍一家住外，他還出租了50多個(gè)房間和樓下檔口，整棟樓平均每個(gè)月也要用2000度電，夏季高峰期還會更多。他當(dāng)時(shí)選擇安裝10千瓦，也是算了下發(fā)電量基本可以供他們這棟樓使用，其實(shí)他們樓頂還有面積可供安裝，只是從成本考慮沒裝那么多。 除了節(jié)省電費(fèi)外，國家還對光伏發(fā)電有補(bǔ)貼，每度電補(bǔ)貼4毛多錢，如果發(fā)電量有多余，還可以每度電5毛多錢賣給供電局，這樣算起來，李永龍只要五六年的時(shí)間就可以收回9萬元的投資成本。

Have you ever thought of installing a photovoltaic unit on your roof to not only power your house, but also sell the excess electricity to the power board? A resident of huihuan Street Office in Zhongkai High-tech Zone in Huizhou has installed a 10-kilowatt photovoltaic (PV) device on his roof, which in theory can generate 10 KWH of electricity per hour. It is by far the largest pv installed capacity for a home in Huizhou.According to calculation, the average annual savings of about 18,000 yuan, as long as five or six years can recover the investment cost of 90,000 yuan.

5 in the morning, the reporter arrived at the HuiHuan neighborhood residents of a building in the village since the building, the building fell a total of six floors, homeowners yong-long li was installed on the roof this year 10 mw photovoltaic power generation equipment, on the same day, ZhongKai mid-term examination of power supply bureau staff also came to his house, and then go to the power supply bureau yong-long li claim bidirectional measuring meters installed, His household generates its own electricity and feeds it into the grid, and the surplus is sold to the power board.

Huizhou resident roof installed solar photovoltaic power generation, at the top of the 6th floor, yong-long li with steel tube set up a 2 meters high hut, hut is covered on the solar silicon, a total of 40 blocks, each 1 m wide, 1.66 meters long, each silicon price 1000 yuan, and other materials, all he spent nearly 90000 yuan, according to the installed capacity of 10 mw, The cost is about 9 yuan per watt.Before the eyes, photovoltaic equipment has been installed for more than 10 days, has begun to generate electricity, the reporter saw from the wall of three-phase photovoltaic grid-connected inverter, a total of 853 kilowatt-hours of electricity, the day of the 5th to 9 o 'clock in the morning, also sent more than 6 kilowatt-hours of electricity. Li yonglong said that 10 kilowatts can theoretically generate 10 kilowatts of electricity per hour, but due to weather conditions, the average can only generate about 7 kilowatts per hour, about 10 hours a day, or about 2,000 kilowatts a month. In addition to Mr. Li's family, he rents out more than 50 rooms and downstairs stalls in the building, which uses an average of 2,000 kilowatt-hours of electricity a month, and more during peak summer months. At that time, he chose to install 10 kilowatts, which is basically enough for their building. In fact, they still have space for installation on the roof, but not so much from the cost point of view. In addition to saving electricity bills, the state also has subsidies for photovoltaic power generation, with subsidies of more than 40 cents per kilowatt hour. If there is excess electricity generation, it can also be sold to the power supply bureau for more than 50 cents per kilowatt hour. Thus, Li Yonglong can recover 90,000 yuan of investment costs in five or six years.
