Over the past few years, solar panel power generation efficiency has grown and solar has become a very profitable investment.
But the actual power generation and savings from your solar system depend on many factors, all of which one needs to consider while analyzing the claims regarding the system’s efficiency, savings, and long-term benefits.
A lot of individuals don’t know what influences the output of a solar power system.
Let’s delve into detail about the major factors that drive and affect solar energy output today. By being aware of these aspects, you will be able to make better purchasing judgments.
– Weather condition
Many of us mistakenly believe that higher temperatures equate to better solar panel performance, but this is simply not true. High temperatures cause a drop in voltage and a reduction in overall power because solar cells have negative temperature coefficient.
There are other points to consider as well.
– Shading
The solar system’s ability to generate electricity will be reduced if the solar panel is covered by full or partial shading. The shading of the building to the solar panels and the self-shading between solar panels must be taken into account while determining the spacing of the solar panel arrays.
– Location
The amount of annual sunshine varies from place to place. In developing a cost-effective solar array for your use, determining the amount of solar radiation received at your site’s location can be determined by the data of latitude, longitude, time and local weather.
Roof orientation
The solar panels’ inclination should be actively modified in response to seasonal, latitude/longitude, and daylight-saving-time shifts. It must face the sun in the proper direction if you want to get the most out of your solar panels. Positioning your solar panels facing true south, and at a tilt angle as per requirement, will yield the best results in terms of energy production and savings.
– Panel’s cleanliness
Photovoltaic power conversion is directly related to the cleanliness of solar panel surfaces. Rainfall, snow, dust, and sandstorms, to name a few environmental conditions, can reduce the effectiveness of solar modules, thus they should be cleaned regularly.
It depends on the location of solar plant and the type of dust which is accumulated on the modules.
Considering all these factors, we must bear in mind that even the most efficient solar panels can be adversely affected by environmental conditions, even with an adequate design, if the aforementioned considerations are not addressed. Saving money on your utility bills is one of the primary reasons you’ve chosen to go solar.
