is solar power different from solar energy?
Posted by admin on Jul 2, 2010
i need to do a project on somesort of energy and decided to do solar energy, i wanted to do how solar energy is used to create electricity and power home however thats pretty much solar power, would solar power still fit in to energy, would doing a project on solar power as an energy project be ok or are they too far apart from eachother?
power and energy are related to each other by the equation:
P = E / T
Where:
P = power
E = energy
T = time
So the amount of power you are using is the amount of energy you use divided by the time it takes to use it in. In other words, power is how fast the energy is coming in. You can rearrange that equation for energy and get:
E = P * T
Energy is the amount of power your using multiplied by the amount of time you’re using it for. If you use 1 kilowatt of power for 1 hour, that’s 1 kilowatt hour (kwh) of energy. kwh is the unit of energy the electric company uses when they bill you.
so yes, solar energy and solar power refer to the same thing, which is converting photons from the sun into electricity.

Detailed project instructions below:
We are going to modify a cheap cell phone to charge off of solar power. Here are the items you will need.
1. Cheap Throwaway Mobile phone
2. Basic small solar panel (available at electronics stores)
3. Standard blocking diode (also get at the electronics store)
Attach the solar panel to the back of the phone with hot glue or epoxy. You can then burn a couple holes in the case with a soldering iron to run the wires through.
Next, burn some grooves into the plastic phone molding so that we can store the wires without them stopping the phone from closing.
Now the fun part!
Solder the positive output of the solar panel to the diode, make sure you wire it to the back end of the diode, you can tell which side is which by looking at the diode itself. Diode’s have a single white line on the end which designates the front, so just wire the solar panel to the side without the white line!
Next, wire the other side of the diode to the phone’s positive battery prong (this should be marked on the phone itself). When that is done take the negative end of the solar panel and wire it to the negative battery prong on the phone.
Now pop in the battery and close up the phone! Your cheap emergency phone is now ready for action!

Reducing Your Energy Needs before Going Green With simple instructions available on how to convert to homemade wind power or DIY solar panels for as little as $200, many people are taking the alternative energy more seriously. When choosing to take on a DIY conversion project the first question most people ask is will one windmill or one large solar panel be enough? There are too many factors involved here to answer that question for you. But one way to start is to ensure your home is efficient in the first place. In this article we will walk you through some steps that will help you reduce your energy consumption before you start converting your home.
Reducing Your Energy Needs
One often overlooked step in converting a home to green power is reducing your energy needs in the first place. The average home uses inefficient lighting, power hungry appliances, and poor heating/cooling solutions. An important step to reducing your energy needs is to look at the inefficiencies in your current system.
Consider: 1. Replacing old incandescent bulbs with fluorescents or led bulbs will cut your power consumption from light in half.
2. Replacing old, inefficient, appliances may reduce your energy bills by as much as 30% by itself.
You should also look at your current heating/cooling solutions. For example an electric hot water heater could potentially be replaced by a solar water heater. Maybe that inefficient air conditioner can be replaced with a more efficient heat exchanger. If you need help choosing more efficient appliances, an excellent resource for this is put out by the Canadian government: http://oee.nrcan.gc.ca/EnerGuide/home.cfm. It’s called Energuide, and it covers everything power consumption of home appliance to energy requirements of large commercial air conditioners.Spend some time looking through that guide and calculating how much you can reduce your power consumption in different areas of your home. By simply taking a look at everything in your home that consumes energy, you will find ways to reduce your energy needs before you start.You don’t necessarily have to go all out and spend $10, 000 replacing everything — but things as simple as changing your lighting will reduce your energy needs before you start your conversion project.
