100W home solar power generation system costs 1780 yuan/set. With TV, fan, lighting, mobile phone charging.
150W home solar power generation system costs 1950 yuan/set. With TV, fan, computer, lighting, mobile phone charging.
The 300W home solar power generation system costs 3,780 yuan/set, with a TV, fan, computer and small refrigerator.
A 450W home solar power generation system costs 5,650 yuan/set, with a refrigerator, washing machine, TV, computer and fan.
The investment cost of large solar energy production systems is higher. Basically, the above types of electricity are sufficient. This is the price of an off-grid solar energy system.

I installeda solar power generation system, it's 300w, how many kilowatt hours of electricity can 72 volts produce on a sunny day< /h3>
Yes Make your idea come true by modifying an electric blanket: Find a blanket 220 volt 40 watt single person electric heater and remove the power cord and textile seams on both sides to reveal the heating wires on both sides. Connect one wire to each turn of heating wire, for a total of 10 wires. Remove 10 wires about 10 turns and connect them in parallel to form one wire; do the same on the other side to become another thread. becomes an electric blanket with a low voltage power supply of 10 to 15 volts. The original total resistance of around 1000 ohms has become around 5 ohms and the power is around 30 watts.
It depends on the weather and whether you are facing the sun. Generally, when the sun is good, it can reach 60 to70% of maximum power, but if it is not direct sunlight, the power will be much lower. Effectiveness is calculated at 8 hours per day. It can only be calculated at 30%, so it can generate about 0.7 to 0.8 kilowatt hours of electricity if there is a tracking device or automatic load adjustment system. , the amount of electricity can be greater.
