Basic Steps To Build Your Own Solar Fountain
If you are curious about how solar panels work, or you just want a fun solar project to work on,
you can build your own solar fountain in a weekend. It's a simple project that you can do by
yourself or with the kids to learn about solar energy. Here are the basics of what is
involved.
First, choose your design. Do you want tiers, a waterfall, a bubbling stream or a geyser? It is
helpful to look through some pictures or do some online research to select the style, size and
shape of your fountain. You will also need to decide whether you want to be able to move it or you
want a permanent installation.
Next, select a pump. You will need to determine the number of gallons per minute and the vertical
lift of the water that your pump will need to handle, based on the volume and height of your
fountain's design. A tall large waterfall fountain will require a more powerful pump than a smaller
and lower babbling brook design. Choose a model that is designed to be immersed completely in water
and runs on direct (DC) current.
The size of the solar panel you will need will be determined by the energy requirements of the pump
you choose and the amount of sunlight your fountain will receive. Choose a larger panel if
you are using a powerful pump to move a lot of water with a long vertical drop, or if you fountain
will be located in an overcast region or a shady spot. Smaller solar panels can be used if you want
to slow down the pump, or if your fountain will receive lots of direct sunlight every
day.
Before you connect the pump and solar panel, or install your fountain permanently, assemble the
components (if it has several tiers or basins) and hook up the plumbing. Test it for flow and
leaks. Pour enough water through it, using a bucket or hose, to make sure that it works as
intended.
If your test is successful, hook up the pump and the PV panel. You will find that your fountain
will speed up and slow down depending on how you position your solar panel. At this point, you can
install your fountain in its permanent location and enjoy your hard work.
