Are solar panels efficient enough.

This national renewable energy laboratory paper quotes studies that show how there is a gradual decline in the efficiency of solar panels over time. The process of converting solar energy will cause the system to degrade in efficiency by approximately 0 5 each year. This is also accounted for when we design your system. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range.

This is very normal for solar equipment and occurs with every system. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. So to derive optimum output from your solar panels make sure they are not kept in shaded areas. Do not expect them to work well without providing enough solar energy.

In other words solar is efficient enough. Solar cells are bound to lose some efficiency as they age. Most of you know that solar panels are efficient enough to feed the needs of your whole home at least when your home is getting sufficient sunlight. If a solar panel has 20 percent efficiency that means it s capable of converting 20 percent of the sunshine hitting it into electricity.

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. Despite that did you know that most solar panels offer efficiency ratings of only 15 20 percent. As you know solar panels need light from the sun for functioning.
