How many solar panels are needed in a solar system?

Of course, the number of panels you’ll need depends on your energy goals. You must know your energy requirements and your current energy consumption. Besides, the amount of sunlight and climate conditions in your area play a major role.

To meet a certain energy need, you can have several combinations of different capacities and amounts of solar panels. For a rough idea, if your house consumes 1000 kWh of energy, you’ll need around 28-30 solar panels of 300W to generate the same amount of energy.

The average household in India consumes 250kWh of energy per month. To generate this amount of energy, you’ll need 7-9 modules of 300W and 9-12 modules of 250W.

Features of 250 & 300W Solar Panel

The main feature of a solar panel is to reduce the high cost of grid electricity by providing free solar electricity. The solar panels ranging from 250W to 300W are highly effective in reducing your dependency on conventional sources of energy. Besides, there are several other unique features of these modules which are discussed below. 

#1. Highly Efficient

The solar panels ranging between 250W-300W are high in efficiency. They are perfect capacity modules you’ll need to run your home appliances with high output performance. 

#2. Low Maintenance

Solar panels are a long term investment that works efficiently for years without demanding high maintenance. Just clean the panels once a year with solar panel cleaning kit to ensure constant efficiency. 

#3. Silent Operation

Unlike other electricity-generating motors and power plants, solar panels do not make unbearable noise while operating. The electricity harnessing process operates silently. 

#4. Less Space Required

This range of solar panels are huge in capacity but that doesn’t mean they require a huge roof area to get installed. You can install the modules just anywhere– on the ground, on the roof or wherever sunlight can be absorbed in abundance.

#5. Highly Durable

These panels can work efficiently for a long period which is about a quarter of a century. Solar panels are the most durable components of a solar system.

#3. Benefits of Solar Panel

Solar panels are financially beneficial for reducing your electricity bill and paying you back within a few years. Meanwhile, they are advantages for the environment as well. All the benefits of 250W and 300W solar panels are listed below. 

  • Reduces your electricity bill to an appreciable amount. 
  • Solar panels ensure a constant power supply since the sun rises and shines every day.
  • They are a consistent source of energy.
  • With a solar system, you can ensure complete energy security. 
  • The modules can make you completely grid-independent.
  • Not too much space is required to install 250W-300W solar panels.
  • Your roof stays protected with solar panels installed over it.
  • A highly durable source of electricity. 
  • Protects the environment by providing a clean and renewable source of energy generation.
  • Solar panels are available in a huge variety of brands, capacities and types and hence you have many options to choose from.

#4. Subsidy on Solar Panels

Solar panels are a revolutionary device that has helped millions of homes and businesses to become energy sufficient. Electricity has reached plenty of remote villages with solar panels used with an off-grid solar system.

But still many people hesitate to switch to solar because of the high prices. To help people financially, the Government of India is providing subsidy on solar panel

According to it,

  • A subsidy of 40% is provided for solar systems having up to 3kW capacity and 
  • A subsidy of 20% is provided for solar systems having 3kW to 10kW capacity.

You are not eligible to apply for a subsidy if your solar system’s capacity increases further.

Frequently Asked Question

Solar panel produce DC power only. With the help of solar inverter, we can convert it into AC power.

Yes off course, a 250 watt solar panel is the best option for home solar system as well as commercial solar system.

Polycrystalline solar panel have an efficiency level up to 17% while monocrystalline solar panels are up to 21% efficient. So comparatively, monocrystalline solar panels are better than polycrystalline solar panel.

See the comparison between: Monocrystalline solar panel Vs. Polycrystalline solar panel.

The dimension of 300 watt solar panel is 1968 X 987 X 40 mm (Approx).

Yes, a 250 watt solar panel will generate power even it is cloudy outside. But in cloudy days, the generation capacity of a PV module will decrease. So it provide you less power in comparison of sunny days.

DC means direct current and AC stands for alternative current. The power produce by solar panel and stored in battery is DC power. But in grid and to run our electrical appliances, AC power is used.

If you have knowledge about installation of a solar panel, then you can install it yourself.

It depends upon the capacity of a solar panel. If you are using 250 watt solar panel then 20 solar panels are needed and if installing 300 watt solar panel then 16 to 17 panels are sufficient for it.

A 300 watt multi crystalline solar panel is available at just Rs.13,200.

An inverter is a device which converts the DC power into AC power. Our solar system produce DC power and to run our appliances, we only need AC power. So for eliminating this mismatch we need an inverter.

Yes, you can use 250 watt solar panel in an off grid solar system. Solar panels are a same component in all type of solar system. They can be use equally in on grid solar system, off grid solar system and even in hybrid solar system.

It depends upon the power consuming capacity of your refrigerator, approximate 2 nos. x 250 watt solar panel will be enough.

No, in India there is no such scheme for commercial purpose solar system. Indian government is providing the subsidy only on home solar system and for non-profit organizations as well.

For buying any capacity solar panel and any type of solar system, you can contact us. We will provide you best solar solutions at adorable prices. You can also visit for our online solar store for the same.
