Are Solar Panels Efficient Enough

In other words solar is efficient enough.

Are solar panels efficient enough.

If a solar panel has 20 percent efficiency that means it s capable of converting 20 percent of the sunshine hitting it into electricity. Via flickr under cc license. So to derive optimum output from your solar panels make sure they are not kept in shaded areas. 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. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. Today most solar providers guarantee that the panels will maintain at least 80 efficiency for 25 years. It works 100 to do the job we need it to do assuming a home has a living room and a kitchen a bathroom and a few other rooms like a study and a bedroom or two chances are its roof has enough space to power that with panels of about 15 efficiency and above.

The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. Do not expect them to work well without providing enough solar energy. Placing your solar panels in shade is one of the major factors that affect the efficiency of your solar systems. This is very normal for solar equipment and occurs with every 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. This is also accounted for when we design your system. The process of converting solar energy will cause the system to degrade in efficiency by approximately 0 5 each year.
