When installed and maintained correctly solar panels will generate electricity that is worth far more than what they cost to purchase and install. This indicates that they are an investment rather than a mere expense. In most cases a solar panel system will pay for itself in approximately 5 years and then continue operating, generating free electricity for many more years after that. So in short, solar panels are worth it, and they are not expensive.

When you install a solar energy system on your property, you save money on your electricity bills and protect yourself against rising electricity rates in the future. How much you can save depends on your area’s utility rates and solar policies, but choosing solar is a wise financial decision no matter where you are located.

Solar energy is considered a renewable energy, as it offers electricity from a virtually unending source—the sun. Going solar reduces greenhouse gas emissions and mitigates climate change, which is critical to protecting humans, wildlife, and ecosystems. Solar energy can also result in fewer air pollutants like sulfur dioxide and particulate matter, which can cause health problems.

ESS have many useful applications, including:

• Supplement Renewables
  Renewable energies such as solar panels or wind power only produce electricity when the sun is out or the wind is blowing. Through ESS supplementation, users can utilize the electricity generated when renewable energy sources are not generating electricity.
  
  
• Peak Shaving
  

  ESS enables users to shift their electricity source by drawing power from batteries during higher-cost daytime hours and recharging them during lower-cost nighttime hours, also known as peak shaving.

• Load Leveling
  When power generation facilities ramp up and ramp down to keep up with the changing demand for electricity. ESS can help flatten out the demand curve by charging when electrical demand is low and discharging when it is high.
  
  
• Uninterruptible Power Supply
  ESS can provide instantaneous protection from power interruptions and are often used in hospitals, data centers, and homes.
