What are the benefits of solar power
Solar power systems derive clean, pure energy from the sun. Installing solar panels on your home helps combat greenhouse gas emissions and reduces our collective dependence on fossil fuel. Traditional electricity is sourced from fossil fuels such as coal and natural gas.

How does solar affect my property values
Studies have shown that homes with solar energy systems sell for more than homes without them. However, your property value will only increase if you own, rather than lease, your solar panel system. In most parts of the country, going solar will actually increase your property value more than a kitchen renovation.

Can I get off grid with solar panels
When you install solar panels on your property, you will still be connected to the grid. This allows you to draw from the grid when your system is not producing all of the power that you need, and send power back to the grid when you produce more than you use. It is possible to go off the grid with a solar energy system that includes battery storage, but it will cost significantly more and is unnecessary for the majority of homeowners.

I am making one of those vibrating bugs using parts from a garden solar light. I have amended my description above thanks to a comment from legalizeshemp420 who pointed out it is an inductor I am replacing with the motor, not a resistor. Thanks again to him.
By replacing the inductor in the Solar Power LED circuit with a vibrating motor we can fabricate a vibrating bug which charges in light and vibrates in the dark, such as when a shadow goes over it.
This is NOT a Solar Popper or a BEAM bot but it is a simple hack to do for a solar experiment.
You could do further work to the circuit to alter the operation but the hack I have done seems to be the simplest and the result is fun.
Main Components
-
I used an Oral B Pulsar toothbrush as the donor of the vibrating motor.
You could also use a vibrating motor from a pager or mobile phone
Solar Panel and circuit board from a garden light.
I used a “Fence Solar Light” from a pound shop.
Main Tools
-
Tin Snips
Soldering Iron
Hot Glue Gun

Generally my projects are for my grandchildren to enjoy. OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap.
