Why Choose a 3kW Solar System?
A 3kW solar system is an ideal choice for small to medium households in India. It can generate 12-15 units of electricity per day, depending on sunlight availability, significantly reducing your reliance on grid power.
1. Affordable and Cost-Effective
Installing a 3kW solar panel system is now cheaper thanks to falling solar panel prices and government subsidies. Even without a subsidy, the return on investment (ROI) is high due to energy savings.
2. Reduced Electricity Bills
A 3kW system can save ₹2,500 – ₹3,500 per month, depending on usage. Over 25 years, this means savings of ₹10-12 lakh.
3. Environmentally Friendly
Solar power is clean and renewable. A 3kW system can reduce carbon emissions by 3-4 metric tons per year, contributing to a greener planet.
4. Low Maintenance Requirements
Solar panels require minimal maintenance—just regular cleaning and periodic inspections to ensure efficiency.
5. Backup Power Option with Batteries
Adding a battery storage system can provide power even during grid outages, increasing reliability.
