Take a look at their own roof can be cost-effective to build power plants

Many people will have reached the newspaper hotline, counseling to establish a "rooftop power plant," the relevant procedures. Reporters consulted on the matter MOS power company. The company responsible person, willing to establish a "rooftop power plant," the public is best to call the customer service telephone 95598 National Grid power company business lobby or go for consultation.

The need for an independent roof and Small Business Committee agreed

"Roof station" school called "distributed photovoltaic rooftop power generation projects," works: installation of solar panels on the roof absorb solar energy, resulting in direct current through the wire imported combiner box, and then converted by the dc ac inverter daily use of 220 VAC.

According to Ma On Shan power company responsible person, a "roof power plant" you first need to separate the roof, and the Small Business Committee agreed, and taking into account the power station in the grid power supply does not affect other users. So, to remind the public of the company: If you go to apply for an account and supply company network, you need to bring ID cards and Small Business Committee consent. Residents upon application, the power company will be given at the agreed working days to reply and provide free access to program development, and network acceptance and commissioning services.

About the "Roof station" equipment problems, Maanshan power company officials, this is the public to purchase their own building. After this, then contact the power company for a free grid access. Building "roof plant" equipment needed is roughly: solar panels, inverters, wires and so on. In general, the life of a photovoltaic device is theoretically about 20 years, with 10 years warranty. Because different PV product quality gaps, the public should be selected carefully.

Invested 8,000 yuan 6-8 years may return the "Roof station" Cost recovery period is longer

Self-built "roof power inverter station", is cost-effective? With Mr. Wang, who lives overseas Haiming Shi Yuan Maanshan City's first new "Roof Station" as an example. According to the city's power company responsible person, "rooftop power station" costs, mainly using solar power plant electronic board costs. Mr. Wang family "Roof station" installed capacity of 1.8 kilowatts. Mr. Wang is installed with five or six square meters of "roof power station" basis, one kilowatt solar electronic panels covering an area of ​​about 3 square meters, about 6 square meters will need a 2-kilowatt solar electronic board, so that Mr. Wang invested The cost is 8,000 yuan. Currently, Anhui execution price per kilowatt-hour (kWh) 0.436 yuan. Mr. Wang investments "Roof station" is relatively small, a rough estimate up his investment costs have 6-8 years to recover.

Currently, only Mr. Wang Shan region an individual household to establish a "roof power station." Maanshan power company staff said, photovoltaic power generation by solar energy, rain or shine, day and night are not the same amount of electricity, so the early years, residents need to be equipped to deploy a battery charge. And a battery takes two or three million. Today, the grid would mean "Roof station" may no longer need batteries, and greatly reduce the construction cost. However, just from an economic point of view, there is still high cost of solar power, long life cycle cost recovery issues.
