Hello. Is it profitable in our time to buy solar batteries? Where do I buy it?
You know that there are dozens of solar panel, inverter, and energy storage manufacturers on the market in the U.S., each offering multiple models of products, making it difficult for even the most research-oriented solar shopper to easily research, aggregate, and compare different solar equipment options. I also recommend to read some iinfo about benefits of investment to solar energy https://a1solarstore.com/blog/how-long-do-solar-panels-last-in-a-nutshell-quite-a-while.html
Anyway every source of renewable energy will be good. Renewable energy, often referred to as clean energy, comes from natural sources or processes that are constantly replenished. For example, sunlight or wind keep shining and blowing, even if their availability depends on time and weather.
For more efficient use of the solar panels I recommend to install solar tracker. It allows you to optimize the process of energy absorption and consequently increases the performance of the solar panels.
