A 5 kW household can be installed on a 100 square meter roofPhotovoltaic power plantThe price of photovoltaic systems on the market is 7 to 9 yuan per watt, which means that it will cost 3.5 yuan to install 5 kW - 45,000 yuan.
The prices of photovoltaic power generation equipment are different and the materials are different. There is monocrystalline silicon and polycrystalline silicon. Prices are different from polycrystalline silicon and have higher power. generation efficiency.
From a national perspective, the cost of solar photovoltaic power generation is 8 to 12 yuan per watt. For example, a 100 square meter roof can produce 10 kilowatts. Calculated at 10 yuan per watt, the final total package price is 100,000 yuan. This price includes design, equipment, construction and connection to the network, etc. The specific price still needs to bebe determined based on demand and installed capacity.
Note:
Photovoltaic power plants are calculated in watts (W), which is the installed capacity, not calculated in terms of area, but installed capacity is also related to the area. .
Roof Types
There are generally three types of roofs on which photovoltaic power generation is installed: colored steel roofs, brick structure roofs and roofs concrete dishes. Different roofs have different installation methods of photovoltaic power plants, and the area of the installed power plants is also different.
600 yuan; generally 1,000 yuan for 250W, calculated based on an area of 1.5 square meters. There are several types of solar energy production. One is crystalline silicon, including monocrystalline silicon and polycrystalline silicon, the other is silicon power generationamorphous cium, which is not crystalline silicon. There is thin film solar power and flexible solar power. Due to the low conversion rate of amorphous solar cells, crystalline silicon solar power generation is now more widely used. I recently purchased a polycrystalline solar panel. The panel is in good condition, carefully welded and the finish is perfect. I can only say one word, magnificent. After testing it again, the voltage and power are sufficient, and I can say one. no more words, satisfied. Recommended!
