Wind generators really produce power when sailing on a reach. Higher wind speeds can produce lots of power.
#Home wind turbine vs solar panels generator
Even if a wind generator produces only 20 watts, it does it 24 hours a day. A wind generator on the other hand, has the potential to produce power 24 hours a day. Solar panels produce power only when the sun shines. Of course, it is important that the occasional gust come often enough to keep up with your power needs. This is because the occasional gusts pack a lot of power in a short period of time. One of the effects of the cube rule is that a location that has an average wind speed reflecting wide swings from low to high velocity may have twice or more energy potential of a location with the same average wind speed which varies very little. For example, a 10 mph wind has 1/8th the power of a 20 mph wind (10 x 10 x 10 = 1000 versus 20 x 20 x 20 = 8000). If the wind speed doubles, the power of the wind (the ability to do work) increases 8 times. The power available from the wind varies as the cube of the wind speed.
On gusty days, a wind turbine may put out a lot of power. We all try to anchor in a lee and get out of the most wind. You also have to consider where you anchor your boat. The winds in the Bahamas are only slightly higher than the southeast coastal US. The Chesapeake Bay area has a higher average wind speed, but that is a yearly average and most of the higher winds occur in the winter when no one is cruising in that area. Along the Texas gulf coast, the average wind speed is higher, but that may be seasonal. To be realistic, the output from wind generators needs to be considered for winds between 10 and 12 mph. Along the United States southeast and gulf coast, the average wind speed is less than 10 mph. The most important decision when considering a wind generator for boats is determining whether or not there is generally enough wind to generate the power to satisfy your needs and it takes a lot of wind. The following will give you some of the pros and cons of each. Wind generators need plenty of wind and solar panels need lots of sun. In this case it depends on where you live or where you cruise, or more accurately on the weather where you live or when you cruise. Should I get a wind generator or solar panels for my boat? As with the answer to many questions, it depends. While cruising, I do not like to run my engine so much just to keep my batteries charged. My sailboat has an outboard and my batteries run down on long weekend cruises. I keep my boat on a mooring and want to keep my batteries charged.
