320W solar panels


Just some sixty years ago solar panels were much less efficient but cost a fortune – about 100$ per watt vs. $0.3-0.5 they cost now. The price of solar energy has been steadily falling. A 320 watt solar panel is no exception.

PV modules with this wattage are quite popular among homeowners. They are powerful enough for residential use, but at the same time are easy to handle, at least compared to higher wattage models. Their size gives you enough freedom to create the most appropriate layout, maximizing the space on your roof. A 320 watt solar panel for RV is also a good idea: their dimensions allow them to fit quite easily on top of almost any vehicle.

Specifications of 320 Watt Solar Panels

On average, 320W solar panels weigh close to 40 lbs, their length is approximately 65 inches and width 43 inches. Monocrystalline modules with this wattage tend to have 60 cells, but polycrystalline ones could have 72 due to lower efficiency.

The efficiency range of 320W solar panels lies between 15 and 22% depending on the brand. The modules also vary in backsheet and frame color, as well as overall aesthetics. Depending on your particular situation, you might also want to consider such characteristics as weather resistance, degradation rate and temperature coefficient. Our store has enough options so that you could find the right one for you.

Features of 320 Watt Solar Panels

  • A 25 year is what you will get in most cases, however, some manufacturers like Silfab offer 30 years
  • Anodized aluminum for frames: lightweight, strong and corrosion-resistant material
  • Amazing efficiency that has increased more than twentyfold compared to the first models ever built
  • PID resistant: no need to worry about potential induced degradation
  • Optimal size and weight for more flexibility

It’s not only efficiency and price that have changed over the recent decades. Many technologies have been developed to fight issues like shading, poor performance on cloudy days and temperature-driven efficiency decrease. As a result, you can now pick a module with the right set of features to harvest the most energy under the conditions in your area.

Our solar calculator can help you adapt a system to your needs.

Average Price of 320 Watt Solar Panels

320 watt solar panel price is determined by the manufacturer. If you are looking for the most efficient modules that won’t break the bank, many Chinese manufacturers can offer you excellent price to efficiency ratios. If quality goes before everything else, there are many European, Japanese and Korean brands that obsess over quality. Generally, their modules are on the expensive side. There is also a third option – the panels made in North America. They may be somewhat less expensive, but their quality standards are equally rigorous. These are by no means rules without exception, just some very general guidelines. You can browse 320 watt solar panels for sale in our store.
