What slogans are hung in the solar photovoltaic production workshop?

For solar power generation, the power generation per square meter is about 120W, and the cost per square meter is about 1,500 yuan. The larger the area, the lower the price.

In 2013, the photovoltaic industry was investigated by European and American antitrust. Overcapacity has led to the collapse of a large number of photovoltaic industries in Zhejiang, and solar energy prices have fallen. This can be checked online at any time

It is recommended to buy a solar water heater at a price of 150-180 yuan per unit, including the installation fee, materials and other expenses. When purchasing, check whether there is reliable after-sales service in the local area

Solar energy For panel power generation, group-scale bidding is recommended. The main reason is that power transformation and storage power equipment are very expensive, and the conversion rate is as high as 17-20. The efficiency is very low, and it is not as good as plant photosynthesis

Nowadays, the national clean energy, photovoltaic The power generation support policy is that those above 10kw can be connected to the grid for free, but the price of electricity recovery is very low and the procedures are cumbersome.

Rooftop photovoltaic power generation with monthly sales of less than RMB 20,000 is tax-free. According to national fiscal and taxation policies, power generation households need to provide sales invoices to power supply companies, and buyers also need invoices to offset costs. Individual power generation does not have industrial and commercial qualifications. Owner qualifications and the procedures for receiving invoices are complicated. Taxes above RMB 20,000 are halved

“The inability to obtain invoices makes it more difficult for power generation households to sell, which is not conducive to promotion. The document issued by the State Administration of Taxation will reduce the tax burden on power generation households.”

According to documents from the State Administration of Taxation, starting from July 1, 2014, when the State Grid Corporation purchases power products from distributed photovoltaic power generation projects, the State Grid Corporation will issue invoices. If the monthly power product sales of the power generation household exceeds 20,000, the invoice will be issued by the State Grid Corporation. Enterprises affiliated with State Grid levy value-added tax based on 50% of the tax payable. Those with monthly sales of less than 20,000 yuan are exempt from VAT.

According to the policy issued by the State Administration of Taxation last year, from October 1, 2013 to December 31, 2015, the tax rate will be calculated based on 3. Taking Gao Song as an example, if his monthly sales are 30,000 yuan, the amount of tax he should pay is 30,000 yuan × 3 × 50 = 450 yuan.

For every kilowatt hour of electricity generated by residents, the state subsidizes 0.42 yuan; the state purchases unused self-generated electricity from residents based on desulfurized coal electricity prices, and the price is also 0.42 yuan per kilowatt hour. Based on the average installation cost of 1 kilowatt of a distributed photovoltaic power generation system of about 10,000 yuan, if the average daily power generation of the 8 kilowatt system is 30 kilowatt-hours and the household electricity consumption is 5 kilowatt-hours per day (not exceeding the first-tier electricity price of 0.52 yuan), it will be approximately Payback of investment in 8 years.

According to the same calculation method, it will take 9-10 years for a 10-kilowatt distributed photovoltaic power generation device to recover its cost.

The average cost recovery period for household photovoltaic power stations is between 8-10 years.
