现在的光伏电站大多采用转换率较高的光伏组件，发电量高， 如果屋顶面积够大，所发的的电基本上能满足企业在白天的用电需要，让企业不再承担高额的峰值、平值电价， 节约用电费用。
一方面，企业可以将自用之外剩余的电力售卖给国家电网。另一方面，国家出于环保的需求，碳排放限额来限制碳排放，这个时候企业可以通过安装光伏电站 加入碳交易系统， 并通过出售清洁电力来获得更多收益。
The recent national standing committee meeting revealed a lot of news, such as raising electricity prices, building scenery bases and increasing renewable energy consumption. When you take it out alone, each one is heavy news, especially good for scenery and new energy. Today we will focus on "raising electricity prices".
Electricity prices rise, high energy consumption is not limited!
The meeting stressed that the fluctuation range of market transaction electricity price should be adjusted from no more than 10% and 15% respectively to no more than 20% in principle. Classified adjustment should be strengthened. For high energy consuming industries, the price formed by market transaction is not limited to 20% upward.
To put it bluntly, the electricity price is going to rise. Especially for high energy consuming enterprises, the increase of electricity charges is not limited. If there is a shortage of electricity, it is entirely possible for electricity charges to soar to more than 1 yuan or 2 yuan, which is not good news for industrial and commercial enterprises, especially high energy consuming enterprises.
It is a good scheme to install photovoltaic and kill many birds with one stone
Installing Photovoltaic on the roof can achieve the benefits of killing multiple birds with one stone, especially for high energy consuming enterprises, which can solve many problems. The installation of photovoltaic can also enjoy the privilege of "unlimited power". Other benefits are listed now.
1. The electricity bill has become less
Most of the current photovoltaic power stations use photovoltaic modules with high conversion rate and high power generation. If the roof area is large enough, the power generated can basically meet the power needs of enterprises in the daytime, so that enterprises will no longer bear high peak and average electricity prices and save electricity costs.
2. There are more revenue channels
On the one hand, enterprises can sell the remaining power for their own use to the State Grid. On the other hand, the state limits carbon emissions for environmental protection. At this time, enterprises can install photovoltaic power stations to join the carbon trading system and obtain more income by selling clean power.
3. The roof has become strong and fashionable
The distributed photovoltaic power generation system is built on the roof of industrial and commercial plants, which will not damage the roof structure, but also effectively reduce the direct sunlight and rain erosion borne by the roof and increase the service life of the roof. In addition, the distributed photovoltaic power generation system itself has a fashionable appearance, and the overall effect is beautiful and atmospheric when combined with the roof of the building.
4. The interior becomes warm in winter and cool in summer
The solar cell module has a wide absorption spectrum range and can greatly absorb solar radiation, so as to play a good heat insulation effect. It can be used as a heat insulation layer in summer and a heat insulation layer in winter to effectively maintain room temperature.
5. Less pollution
Photovoltaic power generation system is a safe, green and sustainable clean energy, with zero emission and pollution in the process of power generation, and can reduce carbon dioxide emission. It can greatly reduce the pollution to the surrounding environment!
