Example text

We’ll break down all the different solar devices for you in a minute, but in order to better understand how they work, let’s first hash out solar energy’s challenges. Limitations of Solar Energy Harvesting the tremendous power available from the sun and using it effectively in our complex lives requires some crafty engineering on our part. This is because of the unique characteristics of solar power. Perhaps the most obvious challenge is availability. What if we want hot water or electricity when the sun isn’t shining?

The most obvious benefit of using solar energy is that it’s free for the taking. Of course, it’s not always here when we need it—and sometimes there’s too much of it where we don’t want it—but in general using solar energy increases our energy independence while decreasing our need to purchase other forms of fuel. This is true both on a personal and a national level. Second, solar energy is renewable. The Earth won’t run out of solar energy; more solar energy falls on the Earth in one hour than our human civilization consumes in a year.

This specific amount of energy can be quantified in peak sun hours, and is measured in blocks of 1,000 watts/m2. A chunk of energy adding up to 1,000 watts/m2 for one hour equals one peak sun hour (for example, 200 watts/m2 for one hour in the morning plus 800 watts/m2 for one hour in the early afternoon equal one peak sun hour). The National Renewable Energy Laboratory has been collecting data from weather stations for decades, and provides average peak sun hour numbers for different regions. For solar resources used year-round, such as solar hot water and solar electricity, it’s fine to just look at the peak sun hour number averaged over the entire year.
