There are 3 houses here, but rental are nearly 40 rooms, he can also living a comfortable life through collect rent, but Tim still spend RMB 800 thousand to build a solar power system, he figured that it is more reliable by selling electricity return than collect rent. Self-build power plant grid-connected to the grid and selling
“this is the most reliable thing I have ever done.” He mean to spend 800 thousand yuan to built roof photovoltaic power generation system.

Tim’s lives in Teng village, There are 3 houses here, but rental are nearly 40 rooms, “our village is a little bit far from the city, it’s not easy to rent out the house, only three or four thousand yuan he can get per month.” He said.
In the end of last year, he have saw other people in the near village built a solar PV power generation system in their own roof. To be simply speaking, it’s just use the utilized space, and it’s equivalent to selling electricity. When other’s “power station” start to operation for a few days, he think it’s very tricky, and he find the same person that responsible for the construction of other’s plant, and start to design for his own.
When his “power station” test by the electricity sector, it is already running two weeks. His roof are widen, it can stand two rows of PV panels, and reached 64 kilowatts of capacity, couple with PV modules, two inverters, DC cables, steel frame, connector, spray cleaning systems, and reconstruction of houses, etc. he spend nearly RMB 800 thousand for the whole construction, the solar power system are RMB 600 thousand yuan, it can be used at least 20 years.
When Dave view the functioning of this system, he said for the self-built individual solar photovoltaic systems, you need to make an application first, and when the electricity sector agreed, they will give you some guidance, after the completion of the network and then tested grid-connected running, “"In the beginning you need to consider more than personal use of the excess electricity is sold or all sold, which also determines the ability to enjoy the preferential national policy level." Said by Dave, Tim and other people are the same, they connected all the electricity grid, and they also need to pay for their own used electricity, “the cost of off grid solar system are about 0.6yuan per unit, and their own used electricity are 0.5yuan per unit,” they cannot consume all power, so they need to purchase storage battery, and the battery life is relatively short, so the running cost are also higher.
One-time investment can be back for six or seven years

Dave introduced, self-built solar photovoltaic systems not only enjoy the subsidized of the province, city, and country, but also sold to nation’s grid after grid connected, the price is RMB1yuan per unit, his system can generate 4000 degree power per a half month, 8000 degree in a month, that means he can get 8000 per month, conservative speaking, he can get RMB 100 thousand per year, and combined with 60 kilowatts capacity, he can also get RMB 120 thousand subsidy from province and city. That’s to say One-time investment can be back for six or seven years. And Tim also agreed and said: “That’s certainly reliable than collect rent.”
Yesterday, Tim made the electricity generated by solar panels to directly connected to his first floor, and through a small inverter to converts for two place light using, “I will charge to my electric car when I don’t need illumination, and the battery can also store.” If you need to used the storage electricity in daily life, the only thing you need it to buy a transformer and connected to electric car.
