1) Understanding your energy needs is essential to determine how much solar you need. Start by making an "energy budget". List all your consumers and their daily usage. For example, if your LED lights use 1W per bulb and you have eight bulbs on for 5 hours a day, that would be 8 Watts for 5 hours or (8x5) 40 Wh (Watt hours). I like to use kWh to keep things consistent. 40 Wh = 0.040 kWh. It's a good idea to list what you're using while at anchor and another list of what you're using while underway (for instance, you don't use your autopilot at anchor). Remember to list everything: fridge, freezer, watermaker, autopilot, nav lights, chart plotters, etc. For example, here aboard Athena, with an electric galley, fridge, freezer, watermaker, two computers, etc, we use an average of 5.5 kWh per day. 2) To give you a quick estimate, use https://globalsolaratlas.info/ to find "Global horizontal irradiation" per day for your location. Take your daily energy consumption from step 1 and divide that by the number of solar hours. In the case of Athena, located in the Caribbean, that would be 5.5kWh per day / 5 sun hours = 1.1 kW solar array. Keep in mind that this is a theoretical number that does not take into account the shading or degradation of the panels over time. Let's add 30%. 1.1 x 1.3 = 1.43 kW. You can now divide that number by the panel's Nominal Power output. In the case of Athena, our panels are 400W SunPower panels. 1430W / 400W = 3.6 panels needed to cover our 5.5 kWh per day consumption. 3) Understand that the amount of solar you can install on a small sailboat is limited by the size of the boat and heavily influenced by shading and, of course, the boat's location. The size of the panels might also be defined by the height of your stanchions or the size of an existing solar arch. Figure out where you're able and willing to install panels. That will dictate the size and number of panels. 4) Use Victron Energy's MPPT Calculator to calculate what MPPT is ideally sized for your solar panels and expected output based on location. Based on our experience in the Caribbean, the estimate provided by the guide is reasonable. https://www.victronenergy.com/mppt-calculator. Remember that it's best practice to avoid combining panels with different specs on the same MPPT. #sailboat #sailboatproject #boatwork #saillife #liveaboard #liveaboardlife #saltlife #sailing #sailingadventure #travel ingcouple #livingonaboat #solar #sailboatsolar

At Rustler we won’t adopt new technology unless we’re sure it’s right for you. Rustler Yachts builds true round-the-world cruising yachts. They are designed to be safe, reliable and beautiful. Many of our owners will sail cross oceans to remote destinations. It’s here, where you entrust your life in the reliability of your yacht. Without internet or home delivery, you have to be self-reliant. For this reason, we usually fit a simple and robust electrical system into our offshore cruisers. A system that can be owner-maintained and repaired easily – anywhere in the world – with nothing more than a screwdriver. Our new R41 Motor Yacht, however, may only be hours from assistance, not weeks. Even so, we wanted to ensure you can rely on the technology on board. We understand the comforts and information motor yacht owners need and have come to expect. We have sought out the most reliable solution to offer these. We didn’t want to use a system that needed a computer and the internet to be repaired by a separate company. And we don’t want a small electrical component to ruin your time on board. We chose the Mastervolt CZone digital control and monitoring network as standard for our R41. In true Rustler fashion, it offers owners a way of manually overriding the network by moving a fuse. We have learnt and designed our system from the ground up, so we are on hand to help. Here's Simon, our head of engineering to explain more.
