It depends. If you only use solar panels for a little bit of time they seem very expensive but if you use solar panels for years and years they seem less expensive. If the prices stay the same they do now, in 15 years solar panels would still cost a bit more than regular energy but the keyword is if. Since there will be more demand in energy and less supply of fossil fuels the prices of those will probably rise. Also since there will be more demand for energy, solar panels will probably cost more to install in the future than now.
Expensiveeeeeeeee (: x
You can use various videos from websites such as Youtube and Instructables to figure out how to build your own solar panel. Efficient ones can be expensive but cheaper to make than purchasing a solar panel for installation.
They are around 500 dollars if you want a medium sized panel
it is more expensive but its probably worth not having to buy fuel etc. for whatever you are going to use it for
Solar panels can be made cheap by finding alternative, lower cost materials and producing them in large quantities. Solar panels are gradually coming own in price but still take many years to recover the initial costs.
it gives energy for your house so its cheap and if you have remains you can sell it to the national grid
Solar panels are ridiculously expensive. A small 130 watt unit costs almost $600. To run your house on solar panels you are looking at thousands of dollars.
If you were some how to break an extremely expensive solar panel you probably can use it to cause harm to another human being.
$80 for a 3x5and up It depends on what you will be using the solar panel for - a super high efficiency panel will be more expensive, but a basic panel will be about that. Keep in mind that you might not even be thinking in terms of "panels" nowadays if you are trying to power your whole home - thin film solar is a flexible alternative that can be cut in many shapes and sizes.
anything under the solar panel doesn't grow. also its extremly expensive but never in your life would you have to pay an electric bill.
YES... but they are not cheap... That depends on how much you want to spend multiplied, by your power requirements. But they are redily available.
I am so glad I came across this question! I build my own solar panel about six months ago and lowered my energy bills by 35%. I am not a master carpenter by any stretch of the imagination, but found this really easy to follow instruction guide. Honestly, it was a fun process and saved me a fortune (some companies charge 10K plus to install a solar panel). Check it out at usetheearth.info/solar
