I made a DIY boat solar panel mounting system which allows the panels to track the sun, whilst receiving very little shading from the existing structure of the boat.
This type of system is very easy to build (using tubular stainless steel and stainless steel fittings with grub screws - no welding is required) and can be modified to suit any boat. I also 'invented' a simple way of fixing the panels in the desired position using Dyneema line and hose clamps. (I've never seen anyone do this before but I find it works very well.)
No specialised tools are needed other than a cheap, small and durable pipe cutter. You can save yourself a fortune by fitting your solar panels yourself and it is an easy job. I spent probably 70% of the build time planning and measuring, and only 30% actually making, so you should allow yourself plenty of time for the planning stage.
In this video I also talk about the MPPT solar charge controller I chose to fit, which can allow your batteries to receive up to 40% more charge compared to the more simple solar charge controllers.
MPPT Solar charge controllers reduce the voltage and simultaneously increase the amperage to the batteries when necessary. With a simple charge controller, if the battery can receive, for instance, 14.5 volts as a maximum charge [before the acid starts to 'boil'] but the charge controller is receiving 19.5 volts from the solar panels at a particular moment, the 'excess' 5 volts will be converted into heat by the charge controller and is therefore lost to the environment before it ever gets to the battery bank. In the above scenario, an MPPT solar charge controller would charge the batteries at 14.5 volts but would use the 'excess' voltage to increase the amperage and this can make a huge difference to the rate of charge. Space is at a premium on a boat, so you might as well get the most you can out of your solar panels!
If anyone has any questions please fee free to ask them in the comments section and I will look forward to reading them.
