When looking at your presentation, I learned that solar power can be used for heat, I thought it could only be used for an energy source. I also learned that solar power is expensive to have. Another thing I learned was that you can get paid from your electric company for using solar power. I found that the government might pay you for converting to solar power interesting. Another thing I found interesting was that it could save you money even though it may cost a lot at first. I would like to find out more about why silicon is used for solar power usage.
