Installing a 3 kW solar system in Uttarakhand is an excellent way to reduce electricity bills and adopt clean, renewable energy. To start, evaluate your daily energy consumption to ensure that a 3 kW system, which generates approximately 12–15 kWh per day, meets your needs. Ensure your rooftop offers at least 300-400 square feet of shadow-free space for optimal solar panel placement.
Once you’ve decided on the system type, hire an MNRE-certified installer or a trusted local provider Like SHRI SOLAR in Uttarakhand. A professional installer will conduct a site survey to assess your roof’s solar potential and design a system tailored to your requirements.
After installation, the system is tested and activated, and for on-grid setups, a net meter is installed by your DISCOM to track energy exports and imports. Don’t forget to take advantage of government subsidies, as the MNRE offers subsidy for residential solar installations, along with state-specific incentives in Uttarakhand.
3KW Off Grid System has Inverter Capacity: 2900Watts & Battery Capacity: 5800Watts. In this power backup system, we will run the following appliances smartly:
| Load | Appliances | Backup Time |
|---|---|---|
| 300 Watts | Lights, Fans, TV, Laptop, Camera | 19 Hrs. |
| 1000 Watts | Lights, Fans, TV, Laptop, Camera, Surface Water Pump | 6 Hrs. |
| 2000 Watts | Lights, Fans, TV, Laptop, Camera, Submersible Water Pump | 3 Hrs. |
Note: We never recommend running home loads exceeding 80% of inverter capacity, as it reduces power backup time. When operating at 50% of inverter capacity, the backup time is approximately 4 hours.

This system generates 15 units per day and powers equipment such as fans, lights, televisions, refrigerators, etc., without relying on grid electricity.
The price of a 3kW Solar System in India is approximately ₹1,80,000 to ₹2,85,000. This includes products, delivery, and installation. Prices may vary based on location and components.
A 3kW system generates 12-15 units daily (4,320-5,400 units annually). It saves approximately ₹84-105 per day and ₹30,240-37,800 annually.

An average cost of a 3kW Solar System with a Battery is Rs. 3,00,000. This includes solar panels, inverter, batteries, balancing system, transportation, installation, and a one-year service warranty. As per MNRE policy, there is no solar subsidy available for systems with a Battery bank.
The average generation of a 3KW Solar System is 12-15 units per day, saving Rs. 66–90 daily or Rs. 1650–2250 monthly. It operates for 300 days annually under typical Indian weather conditions. Monocrystalline panels generate 30% more power in low-light or cloudy weather compared to polycrystalline panels.
Yes, 3kW solar power is sufficient for an ideal home, provided the solar panels, inverter, and batteries are chosen according to the household's energy needs.
A single inverter AC along with basic home appliances can run on a 3KW system, but the total power consumption must be measured and optimized.
A solar inverter is the central component of a solar system. A 3KW inverter typically operates at 48V input voltage and has an 80%-90% maximum load capacity. It can connect to 4 batteries (12V each) or a single lithium battery. Choose wisely for reliability and efficiency.
The total cost of a 3KW solar system (off-grid, on-grid, or hybrid) ranges from Rs. 1,80,000 to Rs. 3,75,000, including installation and transportation. Additional costs may apply for civil work and maintenance.
With the latest high-efficiency panels (22.5%+), a 3KW system requires around 146 sq. ft. for installation, with direct sunlight for 7–8 hours daily. Panel count depends on wattage: fewer panels are needed for higher efficiency modules.
A 3KW system generates 15–18 units daily, producing 4500–5400 units yearly. Output depends on solar technology, weather, maintenance, and system type. Use tools like NREL's solar panel calculator for location-specific predictions.
