390 Watt Solar Panels

The 390 watt solar panels presented on our website are a full-fledged alternative to central power plants. It is believed that the efficiency of such an autonomous solar system depends on the intensity of sunlight. The better the illumination, the more power your system will generate. Therefore, weather and climatic conditions are equally significant factors affecting productivity.

However, the innovative technologies used in these panels allow you to achieve superior performance in low light conditions in the morning, evening, and on cloudy days, increasing the module's power output and the overall output of the solar system.

Advantages of 390 Watt Solar Panel

The main advantages of 390 watt solar panels are:

  • cost efficiency. During peak sun hours (5 on average in the United States), a 390 Watt solar panel produces 390 * 5 = 1950 W per day. With an average consumption of 800-900 kW per month, you will have enough energy with only 13-16 mounted  390 Watt solar panels;
  • compactness. The next advantage of 390W solar panels is that you need fewer of them than less power ones. Thus you will save the space on the roof;
  • low maintenance costs. Solar panels are quite durable, and their product warranty reaches 10 years or more.

Average Price of 390 Watt Solar Panels

The average 390 watt solar panel price usually does not exceed $300, fully paying for itself in the first couple of years of use (if you sell surplus energy through the Net Metering program, it will happen even faster). However, since solar technology is constantly evolving, it can be assumed that panel prices will decline in the future. This means that the payback of these devices will come earlier.

Size of 390 Watt Solar Panels

The standard size of 390 watt solar panels is 72 cells, and its dimensions are compact enough to set an installation in a small area - for example, on the roof.

You can buy 390w solar panels from leading manufacturers at the best price on our website. You can also get advice from our experts about your solar system design.
