Other NESL Solar Power System

NESL also provides solutions in case of any emergency while outdoor. It is a Foldable Solar Power Box, which provides power for car batteries, RV batteries and other 12V batteries.

Problems & Costs

NESL is a very small company. Hence, the major problem could arise when the company shuts down. In that scenario, the 25 years warranty would stand null. However, since it is a state owned company and given the love of Chinese Government for the solar sector in China, let’s hope the company does not close. The panels are efficient with quality certifications and strict quality control.

Price wise these panels are very affordable. NESL panels are very cheap, the price ranges between 60 ~ 70 cents per watt.
