The off-grid cost of a solar power plant is 7.5-10 yuan/W according to plate A, and the grid-connected cost is 4.2-5 yuan/W
Off-grid. The network cost is 30*1,000*10=300,000 yuan.
Connected to the 30*1,000*4.2=126,000 yuan network. Of course you have to add 20% profit and labor. when you will get it.
If it's cheaper than that, the estimate is just a false report on power
How much solar generator is needed to use 100 kilowatt hours of electricity per day
1. Don't worry about whether the roof can support the weight
2. It does not matter if the roof is divided into sun-facing and sun-facing surfaces
3. Calculated only on the basis of 250 square meters
4. Using the most common 195W monocrystalline modules, size 1580 x 808mm, each room is approximately 1.3 square meters, 250 square meters can accommodate 190 units, totaling 37050W.to form a network-connected system. Based on the system efficiency of 0.8, the maximum power output per unit time is 29,640 W, or approximately 30 kW
5. lighting Under normal circumstances, 30 kW can be generated per hour; in fact, this duration can only be 2 hours per day, which means that 30 kW can be guaranteed to be used for 2 hours at most, and the power generated at other times will be less and not enough.
6. Considering the previous three questions, the actual installed capacity is significantly lower than the calculated one.
Approximately 30 KW of solar panels are required
The specific calculation formula is as follows:< /p>
Based on local sunshine duration of 8 hours, 100*1000*130%*150%/8=24.4KW.
A 30 KW solar generator is therefore more suitable
