3/22/2022 Custom Marine Products Releases a New Shade Tolerant Flexible Solar Panel
Most of us have shading on our boats from rigging, equipment poles or other boat structures. Reduction in performance due to shading is a significant issue for solar panels. We at Custom Marine Products have developed a new panel design that significantly reduces the impact of shading and clouds on solar panel performance.
First, a bit of background on how typical solar panels are designed. Solar cells are wired in series to get the panel voltage up to a level that is appropriate for its application. These series strings usually go down and up the length of the panel. A solar panel may have one to 5 series strings. Higher quality solar panels have the cell strings isolated with diodes so a shaded string does not reduce the performance of unshaded strings. If there is shading across the panel, each shaded series string is significantly reduced in power output.
Our new CMPower shade tolerant solar panel is designed with multiple shorter strings of half-cut solar cells. These flexible panels have four strings (four quadrants) all isolated with diodes. The result is a panel that will perform well with boom shading across the panel. In fact, our testing indicates that these panels have double the output of a standard panel in shaded conditions. These panels are currently available in 115 watt and 145 watt sizes. The junction box and wires are in the center of the panel rather than at an outside edge. This may be problematic for some installations.
See diagrams below for clarification.

11/1/2019 LiFePO4 Batteries - Why Bluetooth is a Very Important Feature for Marine Application
First some background - solar controller
I look at the solar controller as a negotiator of sorts. It uses MPPT (Maximum Power Point Tracking) to determine the best combination of voltage and amperage to pull the maximum power (Watts) from the solar panels. The MPP will continually vary depending on the panel design, sun angle and shading. The solar controller also senses what is the best voltage and amperage combination (Watts) for the battery bank. V x I = Watts. Watts into the controller from the solar panels about equals watts out to the batteries minus conversion efficiencies. So the solar controller negotiates the best power from the panels and best power to the batteries. While the solar controller senses the voltage of the batteries to determine how much power to supply to them (charge), it has no way of sensing what has been or is being taken out of them (discharge).
Some more background - LiFePO4 batteries
The discharge curve for LiFEPO4 batteries is very flat. They supply a steady voltage of between 13 and 13.4 volts up until 95% of full discharge. This is unlike lead acid batteries that reduce in voltage from 13 to 11 or less volts as they discharge. Thus, voltage only is not an accurate way to determine the state of charge (SoC) of LiFePO4 batteries.
Determining LIFePO4 battery SoC
There are two ways to determine the SoC of LiFePO4 batteries; an external battery monitor or information directly from the Battery Management System (BMS). A battery monitor (Victron makes one) has a shunt on the negative wire between the batteries and the battery chargers and appliances using power. The battery monitor measures the power crossing the shunt in both directions (charge and discharge) and computes the State of Charge of the battery bank. This technique can be reasonably accurate but most battery monitors are designed for lead acid and AGM batteries and have to be reprogrammed for LiFePO4 because LiFePO4 batteries charge so much more efficiently than lead acid. The battery monitor has enough data to compute the SoC but can be inaccurate because battery charging efficiencies vary. The diagram below may be helpful.
A well designed battery management system (BMS) can measure the charge and discharge rate and the battery voltage and accurately compute the SoC for each battery in the bank. The BMS can also compute the time to full charge and the time to full discharge. In addition, the BMS monitors and manages the SoC of each of the 4 cells within a LiFePO4 battery so it can provide diagnostic data to identify a potential balancing issue which could lead to a potential failure.
All this information can be made available through a well designed BMS Bluetooth App.

4/23/2019 - You may be able to get a solar tax credit for your marine solar system; both state and federal.
We have all heard about tax credits for putting solar on our home but what about for our boat? Sure, why not?
The US Federal Government offers a solar energy tax credit, applicable to your second home. If you have a head and galley onboard and your boat is docked in the United States, your boat qualifies as a second home. This tax credit,extended to December 31, 2019, is a 30% credit on qualified expenditures to purchase and install solar panels placed in service after 2008. This credit can be retroactive – as long as the solar system was placed into service after January 1, 2006.
The Department of Energy website gives a simplified description of the energy tax credit: http://energy.gov/savings/residential-renewable-energy-tax-credit. The actual IRS form is easy to fill out: http://www.irs.gov/pub/irs-pdf/f5695.pdf. It may also worth investigating your state government solar tax credit.

5 Hours Average Sun
2/17/2019 - The Importance of Solar Cell Quality - Not All 100 Watt Solar Panels Are Created Equal
High quality high performance solar cells will produce more power at various sun angles than lower quality solar cells; up to 30% more power. An important consideration in determining how much solar power you need is how many watt hours or amp hours of power you can expect to generate in a 24 hour period. Let's say you cruise in an area that receives an average of 5 hours of full sun a day. The average is computed based on the seasonal sun angle and the sun angle from morning through evening. A 100 watt solar panel with average efficiency solar cells may produce 100 watts x 5 hours or 500 watt hours of power in a day. At 13 volts that's about 38 amp hours in a day. A 100 watt panel with high efficiency solar cells will produce up to 30% more power in a day or 100 watts x 6.5 effective hours or 650 watt hours of power in a day. At 13 volts, that's about 50 amp hours in a day. 38 amp hours vs. 50 amp hours in a day is significant on a boat. Add more panels in the mix, say 400 watts and we see 152 amp hours vs.200 amp hours, a difference of 48 amp hours. This simple analysis does not take into consideration the impact of clouds or shading both of which will make the disparity even greater. Clearly, the higher the quality of the solar cells the more power produced over time.

Our 140 and 175 watt marine solar panels have the highest output per square inch of any marine solar panels on the market that we are aware of. That's good news for us boaters who have limited space for solar.

8/15/2018 - Semi-flexible Marine Solar Panels with ETFE Laminates -
CMP has announced that all marine grade semi-flexible solar panels now contain ETFE laminates. ETFE is a material that will not turn cloudy due to absorption of moisture, is UV resistant, is scratch resistant and allows the maximum spectrum of the sun's light to pass through onto the solar cell. The result is a highly durable, high efficiency (greater than 22%), high output solar panel. TPT and TCP laminates initially look the same as ETFE but tend to degrade in a relatively short period of time.
