Are Solar Panels Efficient Enough

Do not expect them to work well without providing enough solar energy.

Are solar panels efficient enough.

As you know solar panels need light from the sun for functioning. The skeptics among us will say wow these panels have a lot of room to become even more efficient. This is very normal for solar equipment and occurs with every system. If a solar panel has 20 percent efficiency that means it s capable of converting 20 percent of the sunshine hitting it into electricity.

The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. The process of converting solar energy will cause the system to degrade in efficiency by approximately 0 5 each year. Via flickr under cc license. This is also accounted for when we design your system.

This national renewable energy laboratory paper quotes studies that show how there is a gradual decline in the efficiency of solar panels over time. Placing your solar panels in shade is one of the major factors that affect the efficiency of your solar systems. Solar cells are bound to lose some efficiency as they age. Today most solar providers guarantee that the panels will maintain at least 80 efficiency for 25 years.

Despite that did you know that most solar panels offer efficiency ratings of only 15 20 percent. In other words solar is efficient enough. So to derive optimum output from your solar panels make sure they are not kept in shaded areas.
