Hail VS aleo solar panel

Can you trust your module Supplier?

Quality and Reliability are key. Be careful who you give your trust to.

1. The choice of components is important.

This is where everything starts, the Bill Of Materials. If great components are selected, then greatness is achievable. But from poor components, only mediocrity can be expected.

2. The production factory matters.

A similar Bill Of Materials used in different locations does not give the same results. The know-how necessary to run a production site can vary depending on the location and the people. Performances can vary depending on location and ownership (own production lines vs OEM).

3. The size of the company is not a good proxy for quality

Supplying modules from a large manufacturer is not a guarantee of quality as those manufacturers generally handle a complex supply chain with multiple BOM, locations and OEM suppliers.
