Solar energy refers to a system that converts sunlight into electricity using solar panels. This electricity can be used for residential, commercial, or industrial purposes.

• Solar panels absorb sunlight and generate electricity.
• This system helps reduce the consumption of fossil fuels like coal, oil, and gas.
• It is environmentally friendly and reduces harmful emissions like carbon dioxide, helping combat global warming.

• Environmentally Beneficial:

  • Reduces reliance on fossil fuels, cutting harmful emissions like carbon dioxide.
  • Decreases air pollution and helps combat global warming.

• Cost-Effective:

  • Cuts electricity bills significantly.
  • Offers a long-term, sustainable solution.

• Health Benefits:

  • Keeps the air clean, reducing harmful particles and gases.

An On-Grid Solar System is directly connected to the power grid (electricity distribution network). It allows you to use the electricity generated by your solar panels during the day and send any excess electricity to the grid. At night or when solar panels are not generating electricity, you can draw power from the grid.

• Daytime:

  • Solar panels capture sunlight and convert it into electricity.
  • This electricity powers your home or business appliances first.
  • If the generated electricity is more than what you need, the excess is sent back to the grid.

• Nighttime:

  • Since solar panels do not generate electricity at night, the system pulls electricity from the grid to meet your power needs.
  • This system is widely adopted in India due to its efficiency and cost-saving benefits.

Net metering is a system offered by the Indian government for on-grid solar systems. It allows:

1. Excess electricity generated during the day to be sent back to the power grid.
2. Electricity to be drawn from the grid when solar panels are not generating, like at night.
3. A calculation of electricity used and supplied at the end of the month to determine billing.

Example: If you generate 100 units and consume 120 units in a month, you only pay for the 20 units consumed. If you generate more electricity than consumed, the excess is credited for future use.

• Cost Savings:

  • Drastically reduces electricity bills as the grid acts as a backup for surplus power.
  • Generates credits for excess electricity supplied to the grid.

• No Battery Required:

  • Batteries are not needed, making the system more cost-effective and easier to maintain.

• Eco-Friendly:

  • Reduces dependence on traditional fossil fuel-based power generation.

• Efficient Energy Use:

  • Ensures that no electricity generated goes to waste.

The Indian government provides subsidies for both residential and housing societies:

1. Residential Solar Systems:

   • ₹30,000 per kW for the first 2 kW.
   • ₹18,000 per kW for additional capacity (up to 3 kW).
   • Total subsidy: ₹78,000 for 3 kW.

2. Housing Societies (Common Meters):

   • ₹18,000 per kW for systems up to 500 kW.

For a 3 kW solar system:

• Approximate Total Cost Depend on Solar Installation Company : The total cost for installing a 3 kW solar system typically ranges between ₹2,30,000 and ₹2,60,000.

Return on Investment:

• The investment is typically recovered within 3 years through savings on electricity bills.
• After 3 years, you can enjoy free electricity for the next 25 years, making it a highly cost-effective and sustainable choice.
• Bisically  

Solar systems typically come with the following warranty coverage:

• Solar Panels: 27-30 years of performance warranty. (From Solar panel manufacturer)
• Inverter: 7–10 years, depending on the manufacturer. (From Inverter manufacturer)
• Other Components (Bos): Usually 1–5 years warranty. (From Solar Installation Company)
