How do solar panels work?

Solar panels work by converting sunlight into electricity through the use of photovoltaic cells. When the light hits the panel surface, free electrons start flowing and a direct current (DC) is created. This DC power is sent to an inverter, which then converts it to alternating current (AC), making it ideal for use in everyday appliances. The excess electricity is then exported to the grid for credits, or stored in rechargeable batteries for use when the sun isn’t out. 

What are the advantages of solar panels?

From industries to institutes, and everything in between, solar panels are changing the energy game for lakhs in India. From reducing your carbon footprint to helping you make your buildings functionally aesthetic, the benefits of solar panels are many. But there is more to solar panels than just that. Solar panels have several advantages like:

 

  • Help in reducing your carbon footprint
  • Lower electricity bills
  • Offer independence from the grid
  • Make your energy future more secure with smart, scalable solutions
  • Can be installed in open spaces in your home or business, ensuring no space wastage
  • Contemporary solar panels can also be integrated into your building design
  • In certain cases, they can help increase property-value over time
  • With the right solar panel design and maintenance, a lot of users also enjoy earning credits by selling their surplus electricity to local DISCOMS.

Do solar panels only work on the roof?

No, solar panels don’t only work on roofs. You can also install solar panels on open land, building facades, carports, agricultural fields, and even balconies. Any spot that receives sufficient sunlight and has enough space for panel installation can have solar panels.

This adaptability of solar panels on different surfaces makes them suitable for everything, from single homes to apartments, commercial buildings, and communities. Yet, if you’re looking for the option that gives you maximum output, rooftop panels are the best choice. 

Solar roof tiles vs solar panels

Many people confuse solar roof tiles with solar panels, but they both answer different needs. While both produce clean energy for you, solar panels are installed on existing roofs and solar roof tiles meld into the design of the building without needing conventional roofing materials.

Generally, solar panels are more practical, have higher efficiency, faster installation, and lower cost. Solar roof tiles on the other hand offer a more aesthetic option for modern homes, and are therefore greatly in demand.

Confused about which one to choose? Here is a deep-dive into understanding the difference between the two. See more!

Can solar panels be used for apartments?

Yes, solar panels can be used for apartments. For apartment use, the solar panels are usually installed on shared rooftop spaces and are used to power the entire facility, and not just individual homes. In some cases, the electricity is shared among several flats through a common meter or net metering arrangement, depending on local regulations. Since such solar setups are installed on a bigger scale, the resident’s welfare associations play a major role in deciding the system design as well as obtaining approvals. With the right system size and design in place, residents can save big while supporting clean energy use.

How to install a solar panel?

Installing a solar panel setup requires careful planning and precise execution for the best results. Although professional help cannot be substituted, it is ideal to understand the end-to-end process to make informed decisions. The process of installation starts with evaluating the available space for setup, identifying your needs, then calculating your system size (in terms of area and number of panels), and choosing the right kind of panel for you. For execution, the panels are first mounted on the roof or ground for maximum exposure, inverters and batteries are setup, all the connections are secured, and inspection is performed to ensure safety. Once approved, the system is switched on and is fit for use.

Once the setup is one and running, required approvals are taken to install a net meter for proper billing.

What is net metering?

Net metering is a billing mechanism that tracks the electricity exchanged between your solar setup and the grid. A solar net meter is a bidirectional meter that tracks the power you consume from the grid (when consumption exceeds generation) as well as the surplus energy you export (when more energy is generated than required).

As is the case with most solar setups, the excess exported electricity is credited in your bill, eventually recovering the cost of your solar installation in just a few years.

How to maintain your solar panels?

Trying to achieve maximum efficiency on your solar setup? Maintenance is key. While solar panels are generally low maintenance, they require basic upkeep for maximum efficiency and long-term usage. This includes cleaning your panels periodically to remove dirt, debris, and dry leaves that might be covering the surface. You also need to check for shade from neighboring trees or building. Like any outdoor structure, solar panels too need to be inspected for wiring, mounts, inverters, or regular wear and damage. Most residential systems need a professional check-up only once per year, and industrial or commercial setups might require a more frequent intervention through solar AMCs.


Wondering how to get started? Here is everything about solar panel maintenance you’ll ever need. See more!

Do solar panels work in extreme weather?

Solar panels are designed to withstand various weather conditions, be it heat, rain, wind, or even cold. The efficiency of the panels in very hot regions falls little, but they keep on generating power as long as sunlight is given. During rains, solar systems work quite effectively. Cloud cover is more important than rainfall, and rain often serves to help clean dust off the panels.

In cold or windy conditions, panels can perform very well because of the lower operating temperatures. Solar panels remain reliable across most extreme weather conditions in India with good installation and quality components.

Frequently asked questions

The frequently asked questions section is a reliable source for unlocking answers to some of the most crucial inquiries. Please refer to this section for any queries you may have.

 

Charging speed depends on the type of charger, the vehicle’s battery capacity and onboard charger limits, and environmental factors like temperature. Higher-power chargers deliver faster energy, but if the car’s onboard system or battery can’t handle that power, speed remains limited. Battery state of charge also matters, with charging slowing as the pack fills to protect its lifespan.

 

Frequent use of DC fast charging can generate more heat in the battery, and repeated high-power sessions might contribute to long-term wear if used constantly. Occasional fast charging is fine, especially with modern thermal management systems, but relying on slower AC charging for routine top-ups at home can help preserve battery health.

 

A widely distributed charging network reduces reliance on only high-power fast chargers and spreads charging points where vehicles naturally stop, such as apartments, workplaces, malls, and transit hubs. This makes routine charging convenient and lowers pressure on grid infrastructure. Placing many normal chargers where vehicles park regularly also improves financial viability and user access across urban and suburban areas.

 

Yes, you can install an EV charger where you live. Most EVs include a basic charger, and you can add a dedicated home charger or wall box with the help of a licensed electrician. Home charging uses your regular electricity supply and adds convenience since you top up overnight. It also tends to cost less than frequent public charging.

 

The cost of setting up a public EV charging station in India varies widely based on scale and charger types. A basic station with slow chargers may cost a few lakh rupees, while a setup with fast DC chargers can run into tens of lakh rupees. Infrastructure costs like land, electrical connections, and equipment also influence this. Government incentives can help lower some of the upfront expenses.

 

Government schemes like the PM E-Drive and state-level policies provide subsidies and incentives to promote EV charging networks. These can include reduced capital costs for setting up stations, financial support for equipment, and regulatory support to speed approvals. States such as Rajasthan and Telangana also offer additional incentives for infrastructure development, helping to expand access across urban and rural areas.
