Hi, I´m Pam, interesting post. I am a second grade teacher in Orange county. Nowadays , most people need to save up cash on their electrical energy bills and one of the most popular methods is through utilizing solar energy. What can we, the average people do to aid save our World? The response may sound strong, but it’s very simple. Build your own solar panel.

Can someone tell me how to know when you update the information on your website? I don’t want to have to remember to come back all the time. Someone said something about a feed? I don’t know what that is. Thank You

Hello! Have been looking into renewable energy sources that i can just setup at home, and solar energy was a definitely on my checklist. The post is just making me want to get some small solar panel systems installed on my roof so bad. I initially planned to buy them, but they are quite expensive at the moment, think im gonna look up a way to build some cells at home and give em a whirl. Well, thanks again for the post, really good insight into this area.

Comment on How many solar panels would you need to equal the energy output of 1kg of U-235? by roderick_young

That’s a bit like asking how many potatoes in a pound, since solar panels comes in different sizes.

But let’s do a factor-of-10 estimate. Let’s say that the solar panels are 200 watts, will get an average of 5 hours of sun per day, for 30 years before they break. Let’s not quibble over efficency and sun-hours and such.

200 w * 3600 sec / hr * 5 hour / day * 365 day / yr * 30 yr = about 4 x 10^10 joules / panel

8 * 10^13 / (4 * 10^10) = 2 x 10^3 = 2000 panels. This is about the size of array that went onto my son’s high school.

This disregards the energy involved in the panel’s manufacture and distribution, and also assumes that the U-235 just magically appears in its refined state. It also ignores the security costs for weapons-grade fissile material. Also, the solar panels can produce usable energy with very little added cost – not true for the Uranium.
