Pros And Cons
How To Pick The Best 500 Watt Solar Generator?
Without getting confused and wasting time, you can simply glance at the below section to filter your selection for the best 500 Watt solar generator.
1. Types of the solar panel
Before proceeding with the purchase of a 500W solar generator, it is better to be acquainted with its types. Without knowing its type, you may end up with the wrong selection that ultimately turns your investment futile. Fundamentally, 3 types of solar panels are prevalent. These types exist depending on the type of solar cells being used. They are described below.
i. Monocrystalline solar panels
Single crystal silicon is used in these panels and they feature a consistent lattice structure. Usually, they are available in black color. The atypical homogeneous structure aids the electrons to travel efficiently and therefore provides more power efficiency. Comparatively, monocrystalline solar panels are more efficient and occupy less space. Also, they come with a longer life span.
ii. Poly crystalline solar panels
Available in dark blue color, these panels feature non-homogeneous structures with several crystal fusions. A little space is allotted for the electrons to travel and so, they are less efficient.
iii. Thin-film solar panels
These panels are prepared by depositing semiconductor material on a ceramic substrate. Special metals are employed as a thin layer like paint over the substrate. The cost is relatively low but the space occupied is more. Furthermore, these panels degrade faster than other types.
2. Power conversion efficiency
A typical 500W solar generator provides efficiency that ranges from 15% to 21%. The efficiency here is defined by the ratio of solar energy that strikes the surface of the panel to the electric energy generated. To obtain higher efficiency, more watts of electricity should be generated per square meter.
The smaller 500W solar generators generate more electricity and need less space. But the only drawback is they are expensive.
3. Temperature coefficient
Because solar generators rely on sunlight for the energy source, occasionally, the cells are exposed to extreme heat. When the temperature goes extremely high, it may cause damage. Also, the power efficiency declines to a limited time. Usually, the temperature coefficient varies from 0 and 0.5. The power output will be higher when the coefficient value reaches closer to 0.
FAQs When Picking The Best 500 Watt Solar Generator
1. How long does the 500 Watt solar generator last?
A classic portable generator station can usually last in the range of 3 hours to 13 hours when the battery is fully charged. So, the best one can last for up to 13 hours. The battery life relies on the battery type, size, and several electronic devices being used with the generator station.
2. How many solar panels can be connected together on a rooftop?
You can either have five 100 watt solar panels or two 250 watt solar panels stringed together on a rooftop.
3. How do solar panels work in solar generators?
The solar panels in a solar generator gather the solar energy and store it in the constructed batteries of the engine. Subsequently, the converter transforms the power from DC to AC prior to discharging it.
4. What is the importance of the charge controller?
The charge controller is vital to regulate and pass the ideal amount of energy to prevent any damage. Also, it ensures good durability. For example, a 30A charge controller will be enough to control a 500W solar panel.
5. Which type of battery is recommended for a 500 Watt solar generator?
It is better to choose Lithium-ion batteries compared to a lead-acid battery. This is because they feature a lightweight design and need less maintenance. Moreover, they come with a longer lifespan.
6. What is the role of an inverter in a solar generator?
The inverter decides the amount of continuous electricity which can be used. A 500W solar generator needs an inverter with a minimum of 400W or higher.
Conclusion – The Best 500 Watt Solar Generator
With the best 500 Watt solar generator, you can perceive efficient power conversion to electric energy, anywhere. Not only they are famous for high efficiency but they are portable, easy to install, stable, and can connect various types of devices. Most of the topmost 500W solar generators are implemented with multiple safety features for complete protection throughout the operation.
