How many solar panels do we need?

When people think about renewable and reasonable energy resources, the first image that comes to mind is solar panels. It is a technology that converts sunlight into electricity and fulfills the world’s basic energy needs. 

We get a non-toxic and environmentally friendly energy source by switching to a solar power system. They are making us energy independent and managing the energy crisis. In this blog, we will discuss which factors contribute to choosing the right size of the solar system for our desired needs.

Factors That Contribute to the Selection of the Solar System

While selecting the size of the solar system, we must consider some points beforehand to make clear what our desired output would be . The following are some factors that play a leading role in the selection of solar panels:

Electricity Needs: 

When a person decides to switch to solar energy, a very clear question comes to mind: How many solar panels do they need? The number of solar panels a person requires depends on their electricity needs. Here you can have a look at your electricity bills and check with an expert to find out the energy consumption.

Exposure to the Sun: 

Solar electricity requires exposure to the sun. Weather conditions, position, right-angle direction, and shade are all factors in determining how much sunshine a solar panel receives. The most crucial aspect is right-angle direction, whereas shadowing limits the amount of sunshine. If no barriers exist, 15% additional solar panels are required to meet demand.

Size of solar panels: 

The size of a solar panel is entirely determined by two factors: the demand for electricity and the efficiency of the panel. The efficiency of solar panels is the most important aspect of measuring their size accurately. Size can be measured in terms of its wattage.

Physical Dimension: 

The dimensions and number of solar panels that can be installed are determined by the size of the region where the system will be installed. High-efficiency panels generate more voltage while taking up less area, whereas larger panels are more costly but produce a greater amount of power.

The efficiency of Solar Panels: 

The quantity of sunshine converted into useful electricity by a solar panel is referred to as its efficiency. It is determined by the quantity of sunshine received by the panel during the day, as well as other elements such as weather conditions, panel quality, and shading.

How many solar panels do we need to power a home?

Calculate the demand for solar panels by taking into account the amount of electricity used on a daily or monthly basis, the size and efficiency of solar panels, as well as the size of the area where the panels will be located. For example, a 6 KWh solar panel system is required if the daily demand is 30 KW and the area receives 5 hours of direct sunlight per day.

How many KW of Solar Panels Do I Need?

Simply divide your annual KWh by 1200 to find the KW (kilowatts) of solar capacity required. So, if the total energy use recorded on your full-year utility bills is 2400 kWh. A 20-kilowatt solar panel system (2400/1200 = 20) is required.

So, in the above article, it is very clear to you which factors are important to note down for the size selection of your solar system. Simplify: you have to calculate your energy consumption, the amount of sunlight available in your area, and the efficiency of solar panels. But also make sure to consult an expert or professional solar installer who can provide you with more accurate information about the size of solar panels according to your energy needs.

FAQs

1.Can Solar panels power an air conditioner?

Yes, but the number of panels required depends on the size & energy consumption of the AC.

Can we get entirely off the grid with the solar system?

It is possible to go off-grid with a sufficient number of panels & proper backup storage system.

Is it worthwhile to invest in solar panels?

Investing in Solar Panels is worthwhile. You get the long-term benefits of energy independence & produce Eco- Friendly energy.
