What to do when there is no sunlight in the solar power system

The thought of living in the sunshine of freedom may inspire many people, but it cannot be ignored that there is no sunshine. All solar power systems are provided with a battery reserve of no less than 3 days. However, situations like this are not suitable in some areas. In this situation, what can you do to avoid a blackout? There are mainly three options to ensure that you still have power: If you want to live completely off the grid, but don't trust the solar panels that provide you with everything The power you need, a backup generator can help you, and the energy is stored in the form of batteries. However, batteries can mean more cost and maintenance along with the complete independence you desire. Another approach is to give up complete independence and connect your house to the national grid. So while the solar panel's electricity is running, you can buy the amount that you need to sell back from utility when your system produces more. However, keep in mind that neither is a perfect option, as government regulations vary from location to location. Maybe your local company doesn't need or want to work with you, and even if they do, the buyback price can be changed. Also, it should be considered as technical issues such as compatibility between homegrown power and slave utilities, sending security issues, etc. Another option you can choose is to use batteries. In this case, you need to keep in mind that only deep cycle batteries can be used. The most commonly used deep cycle batteries are lead-acid batteries (sealed and vented) and nickel-cadmium batteries, both of which have different pros and cons.
