Understanding Solar Panel Performance Everything You Need to Know

Expressed as a percentage, the efficiency of a Residential Construction Services in Lahore corresponds to the ratio between the amount of energy produced by the panel and the amount of solar energy it receives. In other words, the efficiency rate is in fact the amount of light (solar energy) that could be converted into electricity by the installation.

How To Know the Efficiency of a Photovoltaic Panel?

Don’t worry, you don’t have to get out your calculator to know the performance of your panels. It is in fact a technical characteristic that the manufacturer indicates in the specifics of his product. Even if it is a theoretical rate, the yield is one of the performance criteria that should be studied when you plan to proceed with the installation of solar panels in your home.

How Does the Power of The Panels Change Over Time?

Like everything, the power of your photovoltaic panel is subject to the passage of time. Thus, it usually decreases by less than 1% each year and this is completely normal: photovoltaic cells age over the seasons and some can even burn out over time. It should also be noted that the decrease occurs mainly during the first years of use. The decrease is then less significant. Today, most manufacturers assure that, even after 25 years of operation, solar panels retain at least 80% of their initial power.

Profitability And Return on Investment of a Solar Panel

For its part, profitability is a fundamental notion that compares the cost of solar installation and the savings it can generate over time. The potential profitability is also often the element that finally convinces individuals to commit to a photovoltaic project.

How To Get the Best Performance of a Solar Panel?

The performance of your solar panels depends on many factors which can be technical or environmental.

Photovoltaic Cell Technology One of The Pillars of Your Yield

At a time of energy transition, research into photovoltaic solar power is intensifying. Clearly, new solutions could be developed in the years to come. There are currently 2 major families on the market: crystalline silicon cells and so-called “thin film” cells.

The Power of The Installation

As seen before, the peak power determines the electrical production capacity of your photovoltaic installation. It, therefore, goes hand in hand with its performance.

The Location of The Solar Panels

This is a key element for the performance of your photovoltaic modules. Indeed, any source of shade (tree, building, mountain, etc.) can have an impact on the level of sunshine of your device and therefore on its performance. It is for this reason that the installer will help you determine the ideal location for your project. On a daily basis, remember to regularly check that nothing is obstructing the sun.

The Outside Temperature

Contrary to what one might think, photovoltaic modules are sensitive to excessively high temperatures. Indeed, the efficiency of the panels decreases when the temperature rises above 25°C. Clearly, solar modules do not like overheating. In some cases, the solution is to opt for an installation with superimposed panels.
