2 kW Solar System Price
The cost of 2 kW solar panels is subject to market fluctuations and varies based on different types and dimensions. When selecting solar panels, it’s crucial to consider inverter specifications. In 2023, the average 2kW solar system price associated with setting up a solar panel system in the USA varies between $17,430 USD and $23,870 USD, factoring in the federal solar tax credit. The typical expense for a solar installation stands at approximately $20,650 USD. When considering the cost per watt ($ USD/W), solar panel rates in 2023 average around $2.95 USD /W (before factoring in incentives).
Below is a breakdown of a 2kW solar energy system across various USA states, without factoring in the federal solar tax credit. Remember that depending on your location, you could be eligible for supplementary state or local solar incentive rebates, further lowering the overall cost. Additionally, you might have the opportunity to generate extra income by trading the solar renewable energy certificates (SRECs) produced by your system.
The following prices of a 2kW solar system in a few states are from 2018. You can also find out what solar panels cost in your area in 2023 with the help of your zip code.

In India, when it comes to the cost of solar systems calculated on a per-watt basis, the starting price for a 2kW solar system is approximately Rs 57.50 INR with the price range extending to about Rs 90.02 INR per watt. This range varies based on the specific type of solar system you choose. The total approximate cost of the solar system in India is around Rs 1,99,000 INR.
Now, let’s have a look at the types of solar panels and their costs:
- If you have a PWM solar inverter, it’s advisable to opt for polycrystalline solar panels. The price of 2kW Polycrystalline Solar panels is Rs 60,000 INR approx.
- Alternatively, if you choose an MPPT solar inverter, you should explore options like monocrystalline solar panels or MONO Perc Half Cut Solar Panels. The price of 2kW Monocrystalline Solar Panels is Rs 70,000 INR approx.
- For those interested in cutting-edge solar panel technology, Bifacial Solar Panels are a viable choice, especially when used in conjunction with an MPPT solar Inverter. The price of 2kW Bifacial Solar Panels is Rs 80,000 INR approx.
The breakdown of the 2kW solar system price as per its components is as follows:
Components | Cost |
Solar Panel stand (4) | Rs 16,000 INR (approx.) |
3 Panel MC4 Connectors pair, 3 Wire In, 1 Wire Out | Rs 1,050 INR (approx.) |
Solar DC Wire, 6 sq mm, 15 meters pair | Rs 2,500 INR (approx.) |
150Ah Solar Battery (2) | Rs 30,000 INR (approx.) |
2500VA/24V Solar Inverter (1) | Rs 25,000 INR (approx.) |
Bi-Facial Solar Panel, 440 – 530 Watt, 14 Cells, 9 Bus Bar | Rs 87,000 INR (approx.) |
Please note that the price of solar can vary based on several variables, so consider these figures as an initial reference. Generally, you can find a 2kW solar system within this price range. If you receive quotes significantly lower or higher from solar providers, seeking further clarification is advisable. Now, let’s find out the number of batteries for a 2kW solar system and their cost.

How Many Batteries for a 2kW Solar System and their Cost?

Batteries of various capacities are readily available, with the 150Ah battery being a commonly utilized size. However, if you require extended backup, it is advisable to choose a 200Ah battery. On the other hand, if your power needs are primarily daytime-based, a 100Ah battery can serve the purpose.
For your reference:
- A 200Ah solar battery is priced at around Rs 18,000 INR.
- The price of a 100Ah solar battery is approximately Rs 10,000 INR.
- The cost of a 150Ah solar battery is Rs 15,000 INR approx.
Number of Batteries for a 2kW Solar System
To determine the required battery capacity for storing the electricity produced by a 2kW solar panel, we must first establish the daily energy output of the 2kW solar panel. Assuming that the solar panel generates electricity for approximately 8 hours each day which is a common occurrence on sunny days, the total daily energy generation would be:
2kW ×— 8 hours = 16 kW
Let’s assume that a 200Ah 48V LifEO4 battery has the capacity to store 9.6kWh of electricity. If we aim to store all the generated electricity directly in these batteries, the quantity of batteries, the quantity of batteries required can be calculated as follows:
Number of batteries = (16 kWh) / (9.6 kWh) = 1.67 batteries
However, since it’s not possible to have a fraction of a battery, you’d need to round up to the nearest whole number. Hence, you would require two 200Ah 48V LiFePO4 batteries to store all the electricity produced by the 2kW solar panel each day.
If you happen to possess inverter batteries at your residence, there’s no necessity to set up an entirely new solar system along with a brand-new solar inverter and solar battery. You can transform your current inverter and battery into a solar-powered inverter and battery by integrating a solar conversion kit.
