How is it Possible to Get Constant Power from Solar Panels?
Do you want your photovoltaic (PV) system to consistently generate solar power than the usual? It will not be impossible but it will be tedious.
Factors of solar panels’ efficiency
First, there are several factors that affect a system’s consistency in generating solar power. These can vary from the area’s temperature, maintenance, radiation, tilting angle, down to the azimuth.
The maintenance and azimuth are easy to manage; meanwhile, the temperature is the real beast you need to tame. Temperature can significantly affect the solar panels’ performance and durability. Thus, you need to constantly make sure that dilemmas like humidity freezing never affects your system.
Furthermore, if you’re specifically demanding for your system to absorb sunlight 24/7, then the only way is to put it in space! The sun never sets there, you know.
So, you see, it is not impossible for solar panels to generate solar power for longer hours — however, you need to put in a lot of effort to materialize this. Now, if you’re only worried about the consistency of solar panels for everyday use, then you should know about efficiency.
Efficiency of solar panels
If you’re aiming for consistency in performance and output, then you have to learn about efficiency.
Basically, solar panel efficiency is the amount of solar irradiation the panels can convert into electricity. The rate at which solar energy falls on panels is called solar irradiance.
What does solar panel efficiency have to do with your need for consistency?
By knowing about efficiency, you can set better expectations regarding consistency in your solar panels.
It’s important to know that high efficiency rates do not automatically mean you’ll generate more solar power. It just means there is less need for more panels since the system does not demand higher solar irradiance.
Case in point: if you are offered two systems both having 500-Watt generating panels with high and low efficiency rates, then you will still get 500 Watts of solar power either way. The only difference is the panels with higher efficiency rate are smaller, meaning they are more efficient.
The key here is to truly know your requirements. If you are eyeing the premium, high-efficiency rate system, you should consider your area, first. Do you have limited space on your roof? If yes, then you should go for it.
As you can see, knowing your needs and the efficiency of panels will help you manage your expectations. If you know what you should get — and what you are about to get — then you can thoroughly discuss better options that align with your goals towards consistency.
Preserve the efficiency of solar panels
Unfortunately, the efficiency of solar panels eventually degrade. What happens during degradation? Little by little, the system’s performance dwindles, leaving your panels unable to absorb sunlight unlike before.
This degradation does not happen quickly; however, you have to watch out for the things that cause it. You have to protect your system against thermal cycling, humidity freeze, damp heat, among many others.
