Polaris solar PV net news: since the State Council released accurate after pro-poor policies, poverty alleviation Office responded positively in all regions, PV accurate poverty poverty alleviation as a major breakthrough in full swing around, then as a solar-related companies, how to cut to the construction of photovoltaic projects to do? Small below-and-run village of 300 households in poverty alleviation projects in Ningxia as an example, take a few photos show you how about PV project built.

A, system capacity to determine

A single roof laying 12 250Wp poly-silicon components using a 3kW inverter-grid

Second, installation

In the roof with installation conditions, parallel installs roofs or best angle. Does not meet the installation requirements of farmers, using selected suitable position focused on installation, then an average distribution to the home.

Immigrant district of Ningxia and run village, unified planning for housing, roof type, is used in the sunny side laying parallel to the roof Assembly.

1, the incorporation

(1) in poverty alleviation projects in the family electrical equipment is not a lot during the day, therefore the use of full Internet access patterns. According to where the village district of transformer capacity, and uses a single low voltage grid-connected inverter, respectively.

2, monitor mode

Poverty alleviation project area is generally of no Internet access, network monitoring, GPRS monitor mode is needed, by communication carriers to upload data to the inverter manufacturer servers, real-time data monitoring through intelligent cloud platform. And run village in Ningxia Province using the GPRS monitor mode, to buy SIM card from phone operator, inverter through upload data from SIM card, monthly consumption flow around 2MB.
