What are ‘peak sun hours’?

Each peak sun hour is defined as one hour when the intensity of sunlight (solar irradiance) reaches an average of 1,000 watts of energy per square meter (roughly 10.5 feet). 

Peak sun hours also vary depending on where your solar panels are placed,which means that the direction and shading all can influence the value of peak sun hours.

How are peak sun hours different from regular sunlight hours?

Regular sunlight hours refer to any time the sun is shining during the day - the hours between sunrise and sunset,while peak sun hours precisely measures the amount of irradiance that will hit the solar panels.

How many peak sun hours does solar lights need?

In 2019, the average electricity consumption of a house in China was 732kWh per month, which is about 24kWh per day. 

We all know that different solar panels have different efficiency and different cities have different solar energy.You can use this data to calculate how many peak sun hours solar lights need.

Two steps to help make more use of solar energy

Although you can’t decide where you live in,there are two steps that can help make more use of solar energy.One is choosing a suitable solar light brand,the other is using a qualified installer because he knows which angle or which area can get most solar energy.
