How to measure the uneven price of photovoltaic power generation system?

How do you choose a PV product when you need a complete PV system? What are the factors affecting the price difference of photovoltaic power generation system? Why are so many prices so different?

1. Solar panels and inverters

As the key components of photovoltaic power generation system, the difference in the price of solar photovoltaic panels and solar cable price in the difference in the cost caused by different quality, the lower price is refurbished or used panels.

The inverter is mainly the choice of power generation and different brands, which will cause the differentiation of the price of photovoltaic power generation system.

Solar panels and inverters as the core of photovoltaic power generation system, not to mention the price, its quality affects the service life, power generation. Price determines quality, and short-term low PV system prices that cause long-term property damage are penny-wise and pound-foolish.

Two, cable and PVC pipe

Regardless of the price of the photovoltaic power generation system, the durability of the cable is also critical.

According to the cable used outdoors more, it is necessary to prevent moisture, sunlight, low temperature resistance, high temperature resistance, UV resistance, or some special environments also need to prevent acid and alkali and other chemicals. Because of the long time to use, the cable will also be added with PVC pipe to do protection.

Three, support frame and bearing

For the support frame, the small problem in the price of the photovoltaic power generation system is that, in order to save costs, Angle iron will be used as the support frame, which is easy to rust and deformation. When connecting and assembling, welding and assembling will be used, which will easily break and collapse, and affect the normal use of the photovoltaic system by customers.

In the load-bearing aspect, to use expansion screws will destroy the waterproof layer, also loose fracture. ​support frame and load bearing for solar panels is very key. such auxiliary relationship will also affect the overall interests, so also need to be careful choice, should not care about the price of the whole system, and choose inferior products, otherwise it will affect your normal use of photovoltaic power generation system.

When considering the price of a photovoltaic power generation system, the most important thing is not to care about the rights and interests of the moment. After all, are hard equipment, comprehensive consideration, quality should also be put in the first place.
