Captivate Customers: Wholesale Solar Signs Solutions for Branding and Engineering Projects

The client had a GOVERNMENT contract to install solar lighting signs in a city. He was looking for HIGH QUALITY solar powered signs and BILLboards. They wanted to install lithium batteries for continuous supply. 

The main requirement was for them to operate via the REMOTE control system. It was divided into two sections one has signs and the other has billboards. Also, the pole has STAND to mount solar panels. 

He shared the initial concept and designs for the FOUNDATIONAL setup. We developed a complete design and sent him for approval. In 3 days, he approved the FINAL design as it was suitable for their PROJECT. 

The first sample is undergoing further testing. This went well and did not need much modification. Production got started in our manufacturing facility

It took 15 days and after that, each billboard and sign was inspected. They went through a detailed testing phase before final shipping. 

We packed them in wooden boxes with extra safety layers. It was enough to secure them during the shipping process. Solar sign lighting and play systems were installed in a short time.
