How To Calculate Number Of Solar Panels Required In India?

Use the methods below to figure out how many solar panels you’ll need to power your home.

  • To calculate your solar panel requirements in kilowatts, divide your typical monthly power use by your average monthly solar power generation (115 kWh if you live in India).
  • Divide your solar energy demand in kilowatts by the wattage of one solar panel (Take one solar panel wattage to be 330 Watt as this is the most common solar panel used in 2020).

Let’s say you live in Mumbai, India, and your house’s typical monthly electricity use is 900 kWh. How many solar panels will your home require? Let’s compute (assuming a 220 watt solar panel).

  • 115 kWh is your average monthly solar power generation. (Because you’re from India.)
  • To calculate the kilowatt of solar panels, divide average monthly power use by average monthly power generation: 900 kWh / 115 kWh = 7.82 kW of solar panels.
  • Divide the 7.82 kilowatts of solar panels by the individual solar panel wattage, which in our case is 330 watts: 7,800 watts / 330 watts = 23.63, or nearly 24 solar panels.

Now use the calculator below to figure out how many solar panels you’ll need to power your home.

You can estimate your average monthly solar power generation to be 110 kWh if your state or country receives comparable amounts of sun hours as India.

If you reside in a cold country or one with less sun hours, disregard this value and instead Google your country’s name with the suffix monthly solar power generation to get a figure for your monthly solar power generation.

How can I figure out how many solar panels I’ll require?

Examine previous utility bills to establish your home’s usual energy usage. You may figure out how many solar panels you’ll need by calculating your household’s hourly energy demand by your area’s peak sunlight hours and dividing by the wattage of each panel. To demonstrate a range, use a low-wattage (150 W) and a high-wattage (370 W) example (ex: 17-42 panels to create 11,000 kWh/year). It’s important to keep in mind that the size of your roof and the amount of sunshine it receives are both important considerations.

All of these calculations will be handled for you if you engage with a professional solar contractor.

For 1000 kWh per month, how many solar panels do I need?

A solar panel system that produces 1,000 kWh per month is required. 24.69 solar panels = 1000 kWh / 40.5 kWh Whew! We arrived at our conclusion after a lot of arithmetic.

Cost of solar off grid system:

In a nutshell, an off-grid solar system is a solar system that is not connected to the energy grid. The energy generated by solar panels is stored in batteries in an off-grid solar system, and when power is needed, the stored electricity is drawn from the batteries to power critical loads.

Note: These are MNRE pricing for a typical type of installation with standard equipment; if your solar panels installation has elevation or top-of-the-line technology, prices would increase by Rs 5,000/kWRs10,000/kW.

Conclusion on Calculating solar panels requirement:

To figure out how many solar panels a home or factory needs, first determine its average monthly consumption (kWh), then divide it by the average monthly solar power generation in your location. This should give you the number of solar panels required to power your home in kilowatts, which you can then divide by the wattage of individual solar panels to get the total number of solar panels required.

In India, the average household’s monthly power use is 250 kWh. As a result, an average Indian home requires a solar system with a capacity of 2.3 kW, or seven 330-watt solar panels.

How many solar panels do I require, according to the calculator PDF?

Divide the required wattage by the wattage of each solar panel (say, 300 watts) to determine the number of solar panels required: Solar panels are required in the amount of 9kW/300 watts per panel, which equals 30 solar panels. To power a house, how many batteries are required?

How many air conditioners can 5kW power?

The 5kW solar system is designed for large homes, workplaces, and retail stores. Customers who have regular power outages in their homes, businesses, and other locations will benefit from UTL’s 5kW solar system. It is equipped with a 5.5kVA solar inverter. It can easily run a 2 ton air conditioner with 2 fans, 8 LED lights, and 1 refrigerator.

The cost of a 5kW solar system is determined by the type of solar system. Three types of 5kW solar systems are available. 1st solar system is on-grid, 2nd solar system is off-grid, and 3rd solar system is hybrid. The 5 kW solar system at UTL produces 20 units per day.

How many air conditioners can a 10kW power supply run?

Solar systems with a capacity of 10 kW are becoming increasingly popular among large houses and small enterprises. It works well in homes with 2-3 air conditioners as well as standard loads such as lighting, fans, television, and washing machine. And, if you utilize a solar battery-based system, your home will always be able to create solar electricity using the sun’s rays and will never run out of power.

How many kilowatts (kW) do I require for solar?

So, how many solar panels do you need to power a home based on these factors? You’ll need to figure out two things to estimate how many solar panels you’ll need without a professional assessment: how much energy you use and how much electricity your panels will produce.

Calculating How Many Kilowatt-Hours Your Home Uses

The average American home uses 10,649 kWh of energy per year, according to the latest figures from the US Energy Information Administration (EIA). This, however, differs from state to state. Consider the following scenario:

Add up the kWh indicated on your last 12 power bills to get a better idea of how much energy you consume annually. The size of your home, the number of occupants, your electricity usage patterns, and the energy efficiency rating of your home gadgets will all influence these figures.

Solar Panel Specific Yield

After you’ve calculated how many kWh your home needs annually, you’ll need to calculate how many kWh each of your solar panels produces over the course of a year. This will vary depending on the type of solar panel used, the roof’s characteristics, and the location’s peak sunlight hours.

In the solar power industry, a common metric used to estimate system capacity is “specific yield or “specific production. This is the annual kWh of energy produced for each kilowatt of installed solar capacity. The amount of sunshine accessible in your location has a big impact on your yield.

Check credible sources like the World Bank solar maps or the National Renewable Energy Laboratory’s solar radiation database to obtain a better sense of the specific yield that can be attained in your location. Divide your annual kWh usage by the specific yield per kilowatt of solar capacity to find how many kW are required to power a home.

For example, if your home uses 15,000 kWh of energy per year and solar panels in your area produce 1,500 kWh/kWp, you’ll need a system with a capacity of roughly 10 kilowatts. Paradise Energy Solutions has also devised a general formula for estimating the size of solar panel system you’ll require.

Simply multiply your annual kWh by 1,200 to get the required solar capacity in kilowatts. So, if your total energy consumption during the last 12 months is 24,000 kWh, you’ll require a 20 kW system (24,000 / 1,200 = 20).
