What’s the Difference of Solar Panels Outputs?


If you’re looking forward to investing in Solar panels, you need to understand the difference between the Solar Panel outputs. You must understand how much wattage your house needs. Will a 310 watt solar panel be sufficient to power up your place or not? Hence, understanding the difference in solar panel output is vital to make a wise and well-informed decision.

What is a Solar panel?

A solar panel comprises photovoltaic cells. These cells absorb the energy from the sun rays that fall on them. This stored energy is then used to generate electricity. People who live

What is meant by Solar panel output?

Solar panel output is expressed in watts. The electricity produced by the Solar panel is its output. Domestic solar panels usually range from 265 watts up to 350 watts. So, a smaller house wouldn’t need a solar panel with a higher wattage. A bigger home will require a solar panel with a relatively greater output.

You might have heard people ask about the size and the output of a solar panel. Solar panel installers can guide you regarding the capacity of the solar panel you will need.

The energy produced by a solar panel

People rate solar panels based on the output of electricity produced per day. Another point to consider is the sunlight hours of a place. The amount of produced energy depends on the amount of sunlight received.

How to calculate the output?

Calculating the output of a solar panel is straightforward. All you have to do is multiply the solar panel’s wattage with the number of sunlight hours it receives. For instance, a 310-watt solar panel receives sunlight for about 5 hours; then, it would generate 1,550 watt-hours (Wh) of electricity per day.

Similarly, a 280-watt solar panel that receives 4 hours of sunlight will produce 1,120 kilowatt-hours.

How much power output does your home need?

There are several things one should consider while picking out a solar panel for their home. Of course, you have to see whether you can afford the 310-watt solar panel price, but more importantly, you have to decide:

  • Usage of electricity
  • What part of the house solar panels will power?

Usually, people don’t entirely rely on solar panels to power their houses. However, if they do, they have to invest in a 310-watt solar panel size or more. If electricity usage is relatively lower than usual, you can opt for a solar panel that serves a lesser output of around 225 – 275 watts.

Folks who want to power their houses with solar panels install more than one solar panel. These solar panels are installed in different places because the amount of sunlight received can vary every day. A 3-bedroom house demands a solar panel that can generate at least 3 or 4 kilowatts peak (kWp).

To calculate the output of more than one solar panel, you will multiply the wattage’s value using the total number of solar panels. A house that has four 300-watt solar panels would produce 1.2 kilowatts.

If you already own the property you want to be solar-powered, you need to contact a solar panel installer. However, if you’re planning on constructing such a house, you must remember that you should have a spacious roof space to install solar panels.

Which solar panels should you get?

Several well-known brands produce top-notch solar panels like LG, Panasonic, Hyundai, and Solaria, etc. Most companies make solar panels that generate a maximum of 400 watts. However, SunPower E-Series produces 435 watts. Commercial buildings require such excellent output.

What to do to maintain your solar panels’ output?

Here are a few tips to keep your solar panels at their best:

  • Avoid dirt: Make sure to keep your solar panels neat and clean. A layer of dirt on the solar panel will hinder the production of electricity.
  • Location: If you want a solar-powered house, you can not possibly live in Mawsynram, where it rains almost all the time. You’ve got to make sure that the solar panels receive the most sunlight. That is the reason why solar panels are usually installed on rooves.
  • Shade: If some part of the solar panel is under the shade, it would significantly affect the output.
