When choosing a solar panel for your home, you need to look for whether it is capable of sufficing your power requirements. 300-watt solar panels (also known as standard rooftop panels) are the perfect fit for your homes. Laptops, television sets, LED lights, stereos, small refrigerators, and vacuum cleaners are some of the average household appliances that can function efficiently when powered by a 300-watt solar panel. Investing in a panel with higher ratings will ensure faster, more efficient conversion of solar energy into electricity.

300-Watt Solar System Price 

A 300-watt solar system is inclusive of a number of components, namely panels, solar batteries, inverters, panel stands, wires, and connectors. Let’s have a look at the pricing of each of these components so that you have a fair idea as to the approximate price of a complete 300-watt solar system.

Solar Panels300-watt solar panel price in India depends on the type of solar panel. You can get a  monocrystalline solar panel for anything between Rs. 8000 to 10000. On the other hand, a polycrystalline solar panel is available from Rs. 10000 to 15000 approximately. Bifola panels too, are available, but they are super expensive and not a popular pick among those looking for residential installations. 

Solar Battery – A 150Ah battery is enough to power a 300 W solar panel. A 150 ah solar battery is priced at Rs. 15000 approximately.

Solar Inverter – The price of a solar inverter for a 300 W solar panel approximately spans between Rs. 20000 to 30000.

If you invest in a complete 300 W solar panel system (inclusive of other essentials such as a panel stand, wires, and connectors), it would cost you anything between Rs. 45000 to 50000. 

Subsidy on 300-Watt Solar Panel

To encourage people to opt for renewable sources of energy to meet their power consumption, the Government of India offers subsidies. These subsidies help promote the usage of solar energy among the masses in both rural and urban areas. The most recent scheme is the Grid Connected Solar Rooftop Program.


Via this scheme, the government has offered a variety of incentives, which includes covering the benchmark cost of solar panels of varying capacities. For panels of 3kW capacity, you have a 40% and for solar panels with higher capacity ranging from 3kW to 10kW, the subsidy is 20%. Considering these subsidies, the cost of a 300-watt solar panel which usually costs between Rs. 10000 to 15000 will come down to Rs 6000 to 9000. 


In times when people hesitate to invest in solar energy equipment due to the cost involved, these subsidies indeed, come in as a breather. Thanks to the subsidy schemes, the number of people opting for solar energy in India has considerably increased.  

How many 300W Solar Panels do I Need?

The number of solar panels you need to invest in depends on various factors such as the size of your home, overall power consumption as well as the number of appliances you intend to use.  Considering that a 300-watt solar panel is exposed to 8 hours of sunlight every day, it can generate around 2.5-kilowatt hours per day. 


Annually, this panel can generate around 900-kilowatt hours, which would be sufficient for the power requirements of a 2BHK home in India.  If your power requirements are higher than 900 kilowatt hours every year, you can purchase multiple 300-watt panels too. 


  • How much does a 300-watt solar panel cost in India?

The pricing varies depending on factors such as the type of solar panel and the brand it belongs to. On average, you can get a 300-watt solar panel for anything between Rs 10000 to 15000. If you opt for the subsidies offered by the Government, the price will reduce considerably.

  • How much does a 300-watt solar system cost?

The entire 300-watt solar system is inclusive of different components such as solar panels, inverter, battery, connectors, wires, and panel stands). For a fully operational solar system, you need each of these elements and merely solar panels will not suffice. The complete solar system will cost you anything between Rs. 45000 to 50000.

  • What size battery do I need for a 300-watt solar panel?

The size of a battery for a solar panel A 300W solar panel can function efficiently with a battery of a minimum of 100 Ah capacity. A 100 Ah battery can draw 1000W and is sufficient if you’re looking to use solar energy for a shorter period. If you want to use the solar panel to draw the battery for a longer period, you will have to invest in a larger battery. 

  • How many batteries can a 300-watt solar panel charge?

A 300-watt solar system can charge one 200Ah battery, two 100Ah batteries, or four 50Ah batteries. Fully charging these batteries would require around 4-6 hours. This however is subject to the extent the battery is discharged as well as the sunlight the solar panel receives.

If any of the above-mentioned batteries are discharged to 50% of their capacities, the 300 W solar system can help recharge the batteries within 6 hours. However, if the batteries are discharged more than 50%, the time taken to charge the batteries fully will be more.

Also, the charging time will be less than 6 hours only if the solar panel receives proper sunlight for 5 hours. If the exposure to sunlight is lesser than 5 hours, the charging time for the batteries would increase. 

  • How large is a 300-watt solar panel?

The average size of a 300-watt solar panel is 64.5 x 39 x 1.6 inches. No 300-watt solar panel is lesser than 5 feet in length and 3 feet in width. The weight of any 300-watt solar panel is around 43 pounds (19 kilograms). The size and weight may vary from brand to brand. 

  • How much electricity can a 300W solar panel produce?

The electricity produced by any solar panel is subject to its exposure to sunlight. If a 300-watt solar panel receives 8 hours of sunlight in a day, it is capable of generating 2.5 kilowatt-hours per day. Annually, the electricity generated by a 300-watt solar panel comes to 900 kilowatt-hours. 

Summing Up

We’ve given you all the details you needed to know about 300-watt solar panel with battery price. After knowing all the information about 300-watt solar panels, e hope switching to solar energy to meet your power consumption requirements will be easier for you.
