1. What about the quality of the mounting support?
A: The quality requirements for solar modules and grid-connected inverter support systems: 10 years without rusting, 20 years without degradation of steel, and 25 years still with some structural stability.
2.Can the excess electricity be sold to the state grid in grid-tied solar system?
A:Right.Excess electricity will get additional benefits. When electricity is insufficient, it will also be replenished through the state grid.The state grid is equivalent to a free power transfer station.
3.Are your grid-tied certifications complete?
A:Sure,We have exported on-grid systems to more than 30 countries, covering Europe, America, Asia, Africa and Australia. The certification is very complete .
4. What if the power generation system shows abnormal power output?
A: 1. whether the module is over-matched 2. whether the module is shaded 3. whether the module is abnormal 4. whether the module orientation and inverter working mode 5. whether the grid connection distance is appropriate.
5.How do your company deal with the problem on quality?
A:Our company has been doing this industry for more than 10 years. It has already had a certain reputation. We will carefully analyze it. If it is indeed our quality problem, you can rest assured that it will do things according to the contract agreement and will never let you have any after the worries, our service team will be happy to serve you.
