With electricity costs continuing to rise, many homeowners are exploring rooftop solar as a long-term solution. Among the various options available, a 3kW solar system has emerged as one of the most popular choices for Indian households due to its balance of affordability, power output and subsidy benefits. It is generally suitable for small to medium-sized homes and can offset a substantial portion of monthly electricity consumption.
What can a 3kW solar system power?
A typical 3kW solar setup can comfortably run most everyday household appliances, including:
8–10 LED lights

How much electricity does it generate?
A 3kW rooftop solar system typically generates around:
12–15 units of electricity per day
360–450 units per month
4,000–5,500 units annually
Actual generation depends on factors such as sunlight availability, weather conditions, panel efficiency and installation angle.
What does a 3kW solar system cost?
The cost varies depending on the type of system, panel brand and installation requirements.

How much roof space is required?
Most 3kW systems require roughly 200–300 square feet of shadow-free rooftop space. Depending on panel wattage, the setup usually consists of six to eight modern solar panels.
Is a 3kW system worth it?
For households consuming around 300–450 units of electricity each month, a 3kW solar system can significantly reduce power bills and may recover its installation cost within three to five years. Since solar panels typically last over 25 years, the long-term savings can be substantial.
With government subsidies, falling equipment costs and rising electricity tariffs, a 3kW system remains one of the most attractive entry points for homeowners considering solar energy.
