New Silent Yachts For Sale

The short answer is yes. Owners can choose to go 100% solar-powered or install diesel engines should higher speeds want to be achieved over longer distances. Silent Yachts can cruise up to 100 miles per day by power acquired through its solar panels. Every day the solar panels are able to generate more power than the total consumption needed for propulsion at cruising speeds plus powering all of the appliances on board. 

The Silent Yachts power system feeds the electric propulsion of the power cat and all of the energy it needs to run the A/C, refrigerators, and other household appliances. Light-weight lithium batteries provide an ample amount of energy for everything on board. The lithium batteries used in Silent Yachts are the most expensive ones on the market, but also the most reliable, safe, and have the longest life span.

Solar panels are integrated to the roof of the flybridge hardtop sections instead of just being bolted on top, resulting in no wind load or resistance againest them. Below is a video explaining how the system functions and operates back when Silent Yachts were originally called "Solar Wave":

Heike and Michael Kohler have sent almost their entire lives on a boat. After more than two decades of using various boats, cruisers, and sailboats on multiple oceans, they became dedicated to finding a better energy source for the propulsion of yachts. Between the years of 2005 and 2009, Heike and Michael tested a number of a multitude of various alternative energy sources. In 2009, SolarWave 46 was launched as a proof of concept for their design. While there are many boats and yachts built that use solar power in some fashion, the Solarwave 46 was the first ocean-going yacht to use solar energy to power everything on board from engines to appliances.

Certainly the solar-powered engines and generators are the distinguishing characteristic, but there are a lot of other features that make each Silent Yacht unique. For example, the molds were created using a CNC-milling machine that is able to contruct particular shapes for an optimized design. The materials used in the hull include a carbon compositie that is then resin-infused for a light-weight, but very strong platform. Every hull is fully insulated and the long-term durability is exceptional thanks to the high-quality resin used in the infusion process.

Silent Yachts recommends the 2 x 135 engines as the best solution. If the owner is making frequest trips from Point A to B (Say Miami to the Bahamas for example) the faster hybrid is recommended. The main differentiator here is cruising speed. If the owner is living on the yacht for an extended period of time, rarely pushes the engines to top speeds, and stays below 12 knots, then the E-Power is recommended.

All of the enery consumers and producers are connected to the bus bar. If there happens to be more power produced than consumed, the excess power goes to re-charge the batteries. If for some reason more power is required than what is produced, the needed power comes from the lithium batteries.

This answer really depends upon sea condition and the weight of the boat (for example components, additional equipment, water toys, etc.). The sustained speed on average though is between 12 and 14 knots, 10 knots with one generator running. It is possible to cruise at 10 knots without a generator running when using the Solar E-Power.
