Many people wonder first about the cost of installing solar panels when they are considering solar installation in their house. However, solar energy solutions are not universally applicable, which can complicate the search for a suitable answer.
One might assume that houses of similar sizes would require solar systems of comparable sizes. Contrary to popular belief, the size of a home does not determine the feasibility of installing a residential solar system. These homes are evaluated based on their electricity consumption and the desired solar coverage.
Providing an accurate estimate for the cost of a solar system solely based on the size of the home is a challenging task, considering the various factors that influence the cost of such a system.
In this blog, we will explore the ideal size of a solar panel system for a 1,000-square-foot house and discuss the cost of solar panel systems in India.
How Much Solar Power Does a 1,000-sq-ft Indian House Need?
For a 1,000-square-foot house in India, a solar power system ranging from 3 kW to 5 kW should meet the typical energy needs. The amount of solar power needed to sustain a 1,000-square-foot house in India depends more on the energy usage of the household rather than the physical dimensions of the house. Now, we can delve deeper into the various factors involved:
1. Energy Consumption Estimate
The energy consumption of a 1,000-square-foot house in India can vary between 150 to 250 kWh per month. This range is influenced by factors such as the number of occupants, appliances used, and lifestyle choices. Annually, this would amount to approximately 1,800 to 3,000 kWh per year.

2. Necessary Solar Power System
With the goal to balance out the energy consumption, solar power can be utilized:
A 3 kW system:
- Ideal for a home that uses approximately 150 to 200 kWh of electricity per month.
- Under optimal conditions, a 3 kW system has the potential to generate approximately 12-15 kWh per day.
- The typical configuration of this system includes approximately 10-12 solar panels.
A 4 kW System:
- Ideal for a home that uses approximately 200 to 250 kWh of electricity per month.
- A 4 kW system has the potential to generate approximately 16-20 kWh per day.
- Approximately 13-16 solar panels would be needed for this system.
A 5 kW system:
- Ideal for higher energy usage, typically ranging from 250 to 300 kWh per month.
- A 5 kW system has the capacity to produce approximately 20-25 kWh of electricity per day.
- A standard setup for this system usually consists of 15-20 solar panels.

Breaking Down the Costs
In 2024, house solar panel system installation costs in India can range from INR 1.5 lakh to INR 5 lakh or more. Let’s analyze these costs to gain a better understanding of how expenses are allocated.
- solar panels: The cost of the solar panels contributes significantly to the overall expenses. Monocrystalline panels are often priced higher per watt compared to polycrystalline or thin-film options due to their high efficiency. The price of 1 kW solar panels can vary between INR 37,500 to INR 42,000, depending on the wattage and type.
- Inverters: The cost of inverters is influenced by the type, with micro-inverters being pricier compared to string inverters. Inverters come in a wide range of prices, starting from INR 20,000 and going up to INR 80,000 or even higher. The cost varies based on factors such as the type of inverter and its capacity.
- Structures for Mounting: Typically, ground-mounted systems tend to have a higher cost compared to rooftop installations. The cost of mounting structures can vary significantly, with prices ranging from INR 10,000 to INR 50,000. The final cost will depend on factors such as the complexity and type of structure.
- Optional Batteries: If batteries are chosen, they will increase the overall cost of the installation. Battery prices can differ significantly, with a range of INR 20,000 to INR 1 lakh or even higher. The cost depends on factors such as capacity and brand.
- Component quality: Although the initial cost of high-quality components may be higher, they may last longer and perform better. When compared to conventional components, the cost difference for high-quality components might range from 10% to 30%.
- Government Subsidies and Incentives: Government subsidies and incentives can greatly reduce the upfront cost of installation, such as the solar rooftop subsidy scheme offered by the government of India. Subsidies have the potential to cover a significant portion of the total cost, varying based on the region and the specific scheme in place.
- Installation Cost: The installation charges encompass the cost of labor, equipment, and other miscellaneous expenses. The cost of installation can fluctuate substantially based on the complexity of the installation. On average, charges can range from INR 20,000 to INR 1 lakh.

Understanding Home Solar Panel Systems
Let’s start with the basics of a home solar panel installation before discussing the cost. A typical system includes solar panels, inverters, mounting structures, wiring, and batteries (for energy storage). The amount of solar panels and inverter capacity depend on numerous factors. These include domestic energy needs and rooftop space. By considering these factors, one can make a decision that meets their needs.
- Discussing solar panels: PV panels, or solar panels, are fundamental to a solar power system. These panels capture sunlight to generate electricity. The Indian market offers three main solar panel types: Mono PERC, Polycrystalline, and half-cut solar panels are efficient but expensive.
- Discussing inverters: Solar panels provide DC electricity, which must be converted to AC for residential use by inverters. Inverters include string and microinverters. String inverters are inexpensive yet have a single point of failure. Microinverters, however more expensive, work better in darkened locations.
- Structures for mounting: Solar panels require a robust mounting structure. You can choose ground- or rooftop-mounted systems. Decisions must take into account space and climate. Mounts that optimise panel angle for sunshine exposure may cost more.
- Batteries optional: Batteries are crucial for storing daytime energy. Batteries are expensive, but they give energy self-sufficiency and durability during power outages.
