We all know that solar energy is transferred into usable electricity for various domestic and industrial uses. Thanks to the presence of solar panels, which do the job of absorbing sunlight and passing it through inverter circuits, and creating usable electricity for homes. Unlike the regular grid, installing solar panels has way more benefits for both the person installing the grid and society as a whole.
With that being said, here are the major reasons for installing solar panels that is making solar energy undeniable, including:
- Rising electricity bills: With a regular power grid using coal, it makes it more susceptible to price rise and volatility.
- Frequent Power Cuts: Solar energy can help mitigate power cuts easily. Depending upon the setup type (on-grid/off-grid/hybrid), a solar panel helps ensure that power remains consistently available at all times.
- Government Subsidies: As of 2025, the PM Surya Ghar Muft Bijli Yojana has seemingly made solar panels extremely affordable for residential installations.
- Long-term Savings: A solar panel usually sustains peak performance for about 20-25 years on average, ensuring a solid longevity of 2 decades.
Types of Panels
There are 4 types of solar panels widely available for domestic use. These include:
- Monocrystalline: Monocrystalline solar panels are made using a single and continuous crystal of silicon. Monocrystalline is the most popular choice of photovoltaic panels available thanks to its incredible efficiency of 16-24%.
- Polycrystalline: Polycrystalline solar panels are made by clustering multiple silicon crystals together. These panels have an efficiency of 13-16%, which is still credible but lower than Monocrystalline.
- Thin-Film: Thin Film solar panels are the lightest of the lot. They hold the best ergonomics of being the lightest weighing panel and are made over materials like glass, metal or even plastic surfaces.
- Bifacial: Bifacial solar panels are the newest variant type, which contains panel surfaces on both sides. Bifacial panels generate 30% more energy than a monofacial panel and have a sublime durability.
Benefits of Solar Energy
Installing solar panels opens multiple benefits for the installer as well as for the society in general. Here are some notable advantages including:
- More savings:. An average solar panel helps reduce by almost 90% from the current price of grid-based bills. Put this in perspective and imagine the hefty savings a person can make over the course of 20 years!
- Long lifespan: A solar panel has a peak of 20-25 years (again, this depends on the type of panel as well).
- Low maintenance: A solar panel requires minimal maintenance. Aside from simple dusting of the panels, users usually need an annual checkup.
- Energy Independence: Solar panels assure energy independence, which essentially makes it immune to users from price hikes and power cuts.
- Increased property value: Lastly, houses with solar panels gain an increase in property valuation in real-estate terms.
How to choose the right panel for Installation?
Here is the right way to assess the right size of solar panel for installation. Figure these factors including:
- Energy requirement: Check your monthly bills and note down the units and additional load factors. You will get the monthly units, which can be then used to deduce daily consumption.
- Roof type & available space: Assess the rooftop condition and the total available space for the panel you would be having. A 1 kW solar panel with components would require 80 sqft of open space.
- Type of Panels to choose: Based on factors like finances, energy requirement and budgetary constraints, you can choose the type of solar panels.
- Budgetary ROI: Assessing personal finances is vital before installing solar panels. Although an average solar panel has around 3-5 years of ROI, it is still a cost-inducing setup and adequate financial planning is required.
- Type of setup (on grid/off grid/hybrid): Check the type of setup you require for your day-to-day needs. All three types are useful in their own rights.
- Subsidy to Avail: Check for any government subsidy eligibility and learn the right way to apply for it.
- Warranty & Efficiency: Check the warranty and efficiency of the panels.
- Installation: Once you have done adjudging your needs, we recommend a trusted MNRE-approved installer like Freyr Energy.
Solar Panel Installation Cost in India
Here is a table that has the cost of solar panels on an average.
| Solar System Size | Solar System Price |
| 1 kw solar panel price | ₹1,10,000 – ₹1,30,000 |
| 2 kw solar panel price | ₹1,70,000 – ₹1,90,000 |
| 3 kilowatt solar panel price | ₹2,30,000 – ₹2,60,000 |
| 5 kw solar panel price | ₹3,50,000 – ₹3,90,000 |
| 10kw solar panel price | ₹6,10,000 – ₹6,40,000 |
The price range for panels comes under a list of factors, including:
- Location Price Change: Different geographical locations and states have different panel prices.
- Inverter: The cost of an inverter makes a huge price difference. There are inverters with different capacities and load points, which add up to the final price of the setup.
- Brand Cost Matters: Installing solar panels from top brands incurs more pricing. This, however, ensures a more efficient performance and durability.
- Mounting Structure: Depending on the type of mounting structure, the prices would vary.
Final thoughts
Installing solar panels is the way forward for the future. As a resident, you can be a part of a larger movement that makes you contribute back to society by reducing the grid-power usage for daily needs.
