According to current regulations, the current value-added tax rate for general taxpayers on electricity sales is 13%.
According to the “Notice of the Ministry of Finance and State Administration of Taxation on the Low Applicable VAT Rate and Simple Method of Collecting VAT on Certain Goods” (Caishui [2009 ] No. 9), general hydroelectricity taxpayers who meet the conditions. The simplified tax calculation can be applied to: Electricity generated by small hydroelectric units at or below the county level. Small hydropower units refer to small hydropower units with an installed capacity of less than 50,000 kilowatts (including 50,000 kilowatts) built by various investment entities.
According to current regulations, the value added tax collection rate for simplified tax calculation is 3%, small hydroelectric unitsThey can therefore apply the simplified tax calculation rate of 3%.
Small hydroelectric generator
If the height H=10 meters, the internal diameter of the pipe is 10 cm and the flow rate is assumed to be 5 meters/second, then< /p >
The flow rate Q =V(3.14 D^2/4)=5*(3.14 *0.10^2/4) = 0.03925 cubic meters/second
Water flow power
P = 9.8QH = 9.8 *0.03925*10 = 3.85 kilowatts,
Considering the efficiency of the turbine and the generator, let's generate 2 kilowatts of electricity! Available to a farmer.
But such a small hydroelectric generator may not be available.
Your head can be obtained by filling the 75 mm diameter pipe with a power of 2 kW. If your 10 cm pipe is not already installed.
If the performance is good, it is recommended to use “double-tube double-jet oblique impact hydroelectric generator”. This is a second generation machine withc a price of about 6,000 yuan.
Solve the lighting problem If it is a type, just use the old "slope type". This is the first generation product. Its performance is not that good, but it is cheap and can be had for around 1500.
