Solar Panels

Looking to buy solar panels for homes, offices, shops, and commercial spaces in 12V/24V at an affordable price range? In the past few years, solar panels (PVs), the 'carbon-free' technology that converts sunlight directly into electricity, have grown rapidly. Since rooftop solar is being installed on roofs and building facades in developed countries, PV Modules are becoming an integral part of consumers' daily lives.

People living in sunny countries will increasingly live in solar houses or receive their electricity from large solar power plants. The Solar Power Industry is set for an exciting future in the 21st century because many governments are passionate about promoting renewable electricity as a part of the 21st century's energy mix.

What is a Photovoltaic Module?

The term photovoltaic is applied to describe the conversion of light into electricity using semiconductor materials. This last is a typical definition of photovoltaics though it would be a little bit deeper, we find that we can separate the terms into two parts. Photo which comes from the term Photons and Voltaics. On the one hand, photons are a bundle of electromagnetic energy. The very basic unit of light you can think of is the very basic unit of nature called an elementary.

On the other hand, we have the word Voltaics, making reference to the concept of electricity. This term originally came from the famous Italian physicist Alessandro Volta, a pioneer on electricity and power. He was credited as the inventor of the electrical battery.

What are the applications of solar panels in India?

The applications of solar panels are primarily used for three major purposes: to reduce electricity bills, to generate electricity, and as an investment opportunity. For Tier 1 and Tier 2 cities of India, solar panels are being installed on rooftops to reduce electricity bills by up to 80% through grid-connected solar systems. Whereas in Tier 3 cities, solar panels are being installed to generate electricity to get power supply 24*7 and anywhere through hybrid solar systems or stand-alone solar systems. At Loom Solar, we have installed solar panels at over 50,000 homes and businesses across India, including rural and remote areas.

Advantages and Disadvantages of Solar PV Systems

Why Should You Install Solar Panels?

The benefits of solar panel installation are to solve frequent power cuts in rural areas, to reduce rising electricity bills of homes and businesses as well as to run flour mill & water pump motors directly on solar energy. Some of our consumers are also installing solar panels to generate extra income from their idle rooftops while also contributing to the better future of the nation for the coming generation.

The benefits of solar panels include power cuts, electricity bills, diesel costs, investment opportunities, and pollution reduction.

What are the parameters for PV Module Testing?

Not surprisingly, most of the electrical parameters of a PV module closely reflect those of its solar cells. However, the efficiency of a module, measured in standard conditions of bright sunlight (1000 W/m2 at 25 degrees C, AM1.5 spectrum), is slightly less than that of the constituent cells because the cells do not fill the module’s area and there are small power losses as sunlight passes through the top cover and encapsulated.

What is the new policy for solar rooftops in India in 2025?

As per the current population, India has approx. 34 crore homes (total population ~ 139 crore). According to the latest information by our government, they have a plan to install solar rooftops in 1 crore homes through the subsidy scheme. They have officially announced that every solar consumer will get a Rs. 50,000 subsidy amount. It’s great news for residential consumers. But the main question is, how many homes are eligible for the subsidy scheme? According to solar professionals, 75% of homes have a 1 kW sanctioned load, and 25% of homes have a 3 kW or above sanctioned load. That means only 25% of homes (8.5 crore homes) are eligible for solar subsidy schemes.

How much do solar panels cost in 2025?

The cost of the solar panel depends on the capacity, the technology that was used to build it, the model, the quality, manufacturer, and brand. A range of solar panel capacities is available, including 10W, 20W, 55W, 225W, 455W, 550W and 575W.

As of 2024, the price of a single solar panel in India will range from ₹25 to ₹30 per watt, including taxes, while the price of a solar panel that is 1 kW will be between Rs. 25,000 and Rs. 30,000, including GST and transportation.

What Does It Cost to Install Solar Panels?

An installation of home solar panels starts at ₹50,000, where you convert your existing inverter battery into one that uses solar power. A small solar system can run essential household appliances such as fans, coolers, lights, and mobile chargers, but if you plan to install a one-kilowatt solar panel, your investment will be higher. A unit costing between ₹60,000 and ₹1,00,000 can run all household appliances except air conditioners and water pumps.

What to consider when buying solar panels for your home

There are broadly 6 features in a solar panel that are available in the Indian Markets.

1. Solar Panel Size – Smaller Solar panels will occupy less space on the rooftop. Hence, a smaller size solar panel will cost more.

Are bifacial solar panels worth it?

Bifacial solar panels are the latest technology solar panels that generate electricity from both sides of the panel – front & back side. The solar cell construction of this solar panel is different from polycrystalline and monocrystalline solar panels. They offer many advantages over traditional solar panels. These can be framed or frameless solar panels.

How to Install Solar Panels at Home?

Solar panels should be installed by professional installers. Any mistake in installing solar panels will lead to lesser efficiency and loss in power generation. 

The standard solar panel installation cost is between ₹8 to ₹12 per watt depending upon location, the distance between the panel and inverter, and weather the installation is off in the on-grid solar system or off-grid solar system. We have installed solar panels in over 50,000 homes across India. Here is the list of solar panel installation stories with unique applications.

How to connect a 24v solar panel to a 12v battery?

The selection of solar panels is based on voltage range, which is available in 10W, 20W, 40W, 50W, 75W, 125W, and 200W with 12V solar panels, which are used to charge a single battery of 12V. But for double inverter battery (24V inverter battery), a 24V solar panel will be used. Loom Solar provides 24V Shark 445 Mono Perc, Shark 550W, Mono Per, Bifacial, Shark 550 W Solar Panel, and 520W DCR Solar Panels.

A solar panel is used for battery charging and saving electricity bills for homes and offices. A battery is a collection of cells that stores power. All lead acid batteries come in 12V and are rechargeable batteries. Now, the basic concept of battery and solar panels is 12V battery should be charged by a 24V solar panel. But there is some confusion – if we need to connect the solar panel and battery directly, then the battery will get damaged after full charge. Here, we can use a charge controller or inverter.

FAQs About Solar Panel

Q: What is a solar panel?

Ans: A solar panel, also called a PV module or solar plate, makes electricity from sunlight. It is made up of many solar cells. When several of these PV modules are linked together in series or parallel, they form a solar panel.

Q: How to make a solar panel?

Ans: Solar panels are made from many solar cells, each producing 0.5 volts and 10 amps. These cells are connected together based on the power needed and placed into a frame, which includes a junction box. To make a solar panel, about 6-7 different materials are needed. In India, two main types of solar panels are made: DCR and Non-DCR. Fully automatic factories are being set up to produce these panels.

Q: How many solar panels are required for a home?

Q: How much electricity does a solar panel produce?

Ans: A 1 kW solar panel can make about 4-5 units of electricity per day. If it works at full power for around 300 days in a year, it will produce about 1,200 to 1,500 units of electricity each year. Using this, you can guess how much electricity your solar system will make. You can also check the expected monthly solar energy for your location with this tool: https://pvwatts.nrel.gov/.

Q: How many types of solar panels are there?

Ans: There are different types of solar panels available in India, with efficiency ranging from 16% to 26.84%.
