How eco-friendly are solar energy systems?

Solar power systems lower the quantity of coal and natural gas burned in power plants by creating clean electricity. This minimizes the number of pollutants and greenhouse gases discharged into the environment, which helps to cause sickness and man-made climate change. Extraction procedures for fossil fuels, such as fracking and surface coal mining, have significant environmental consequences, such as land degradation, water contamination, and mine fires.


The installation of solar power systems benefits the environment. So how do the three distinct types of systems, including those that use batteries, compare in terms of their environmental impact today? Click here to know 51.2V 200AH Wall-mounted Home Energy Storage System.


Grid-connected without batteries

The vast majority of existing solar systems are connected to the grid and do not have batteries. The power from the solar panels is first used by the on-site equipment, and any excess is exported to the grid for use by your neighbors. Any shortfall is provided by the grid, and this setup is relatively cheap and efficient, using simple inverters that depend on grid stability. However, it is not very self-sufficient, as the inverter will shut down if a grid outage occurs.


Since the grid has the least amount of energy storage, the centralized power plant reduces its output to compensate whenever your solar system is operating. Solar power reduces the power plant's output accordingly per kilowatt hour. The benefits are even greater because the power plant not only has to meet the needs of the end user but also has to bear the losses incurred in the power lines, which can exceed 20% in remote areas. Some argue that because coal-fired power stations lack flexibility, they will consume coal at the same rate regardless of the amount of solar power generated, when in fact they respond quickly enough.


Grid-connected (hybrid) batteries

Batteries are used in grid-connected solar power systems for a variety of reasons. Some of these systems are particularly self-sufficient since they can power your equipment even when the power goes out. With enough batteries and solar panels, importing from the grid might become an uncommon occurrence. Adding batteries, however, will not enhance your net influence on fossil fuel generation. Of course, you will import less power from the grid at night and output less power during the day. Because batteries lose power when charging and discharging, the house will require somewhat more power than it would without them.


Off-grid

With the price of batteries dropping, many people are now considering cutting the connection to the grid. This is certainly the most self-sufficient option, but its adoption will be limited by cost: a completely off-grid system can cost around RMB 200,000 for a typical home. From an environmental perspective, there are drawbacks to disconnecting from the grid. At current prices, it makes sense to install a relatively large number of solar panels to help power the house during cloudy winter weeks or the rainy season. Since off-grid systems cannot output to the grid, excess power generation on sunny days will be wasted. Off-grid homes often use diesel generators to get through the worst weeks or to pay for extra consumption, such as guests. This small amount of fossil fuel use should also be taken into account. Where grid-connected solar panels are available, grid-tied solar panels are more environmentally friendly than off-grid solar panels.


Conclusion

A grid-connected solar system that does not require batteries is a very environmentally friendly option because excess solar energy is fed into the grid, reducing the damage caused by fossil fuels.


Installing grid-connected batteries does not always directly benefit the environment, but it does aid in the development of economies of scale in battery manufacturing and installation, which will aid in our long-term transition to a 100% renewable electricity system.


Batteries may have direct environmental benefits in some cases, such as when they contribute to mega solar systems, avoid grid infrastructure construction or upgrades, or enable environmentally beneficial off-grid lifestyles.
