What role can the 610w price of jinko solar panels play?

With the increase in the capacity of photovoltaic power stations, in many places, due to consumption reasons, newly installed photovoltaic systems are not allowed to be fed into the power grid. When the photovoltaic power exceeds the load power, the excess part can only be wasted, which will reduce the power station's revenue. If the time is long and the wasted power is large, it may have no investment value. Installing anti-backflow and energy storage devices can not only reduce the power loss caused by anti-backflow but also serve as a backup power source for the load, which is more economical than a simple grid-connected anti-backflow system.

jinko solar panels 610w price: Install current sensors at the grid connection point. When current is detected flowing into the power grid, the photovoltaic output power remains unchanged. Activate the bidirectional converter to store the excess electrical energy in the battery and release it when the photovoltaic power decreases or the load power increases. From a cost perspective, installing a reverse flow prevention system requires the addition of energy storage equipment, including energy storage converters and batteries, with a price of approximately 2,000 yuan per kilowatt-hour. When allocated to each kilowatt-hour, it is about 0.5 yuan. The cost is still relatively high. Therefore, when designing an energy storage system, the following three points should be noted:

First, it is necessary to track the power generation curve of photovoltaic power and the power consumption curve of the load, and calculate the configuration of energy storage.

Second, choose the technical solution for energy storage. From the perspective of cost, the AC coupling design is flexible and more suitable for anti-backflow energy storage.

Thirdly, it is necessary to select the right anti-backflow detection points to install current sensors. If the selection is inappropriate, a lot of electricity may be wasted.

For small systems with a power of less than 30kW, if the proportion of photovoltaic self-consumption is over 80%, the excess electricity is not much, the total daily kilowatt-hour is below 15 kilowatt-hours, or the daily electricity bill is below 15 yuan. The electricity price is lower than 0.5 yuan, approaching the cost per kilowatt-hour of installing energy storage. It is recommended to configure anti-backflow devices, which are cost-effective, safe and reliable. If the excess capacity of photovoltaic power exceeds 20%, or the excess power of photovoltaic power exceeds 30kW, the daily electricity consumption exceeds 100 kilowatt-hours, and the electricity price is higher than 0.5 yuan, it is recommended to install energy storage.
