9/7/17 – 1998 Lazy Daze w/ Chevy Chassis, 26’

This client is a collector of Lazy Daze RV's.  This is the 3rd solar and mobile power system we have installed for him.  He told us his next Lazy Daze will be for his retirement, and he’ll bring it in to us for one final AM Solar system installation.  We hope he’s enjoying a few “lazy days” while dry camping, and using a little solar power to run some of his light DC loads.

We like to install our systems as cleanly, and as easy to manage as possible.  These clients came to us with an existing battery bank wired by the manufacturer that worked well enough, but wasn’t quite as clean or as orderly as we would prefer.  During the process of installing their new battery monitor we cleaned up the battery bank and decluttered some of the wiring to create a more efficient battery bank.  We also installed 1440 Watts of solar power which will go a long way towards offsetting the power used by their residential fridge.

9/13/17 – 5th Wheel Tahoe, 23’

These clients came to us wanting to have a small amount of solar power installed with the potential to install more at a later date.  We installed one SF180 solar panel with a 50A charge controller and wired the rig with 4-gauge cable from the battery bank to the roof.  The 50A charge controller is powerful enough for them to install three more SF180 panels.  By installing the oversized charge controller now, we eliminated the need for them to install a new charge controller (saving them some money) when they expand in the future.  The roof C-Box was also installed with expansion in mind.

The Benefits of Lithium Batteries

Lithium Batteries for RV.jpg

Lithium Batteries have long been the best battery option for going solar. They have numerous benefits and advantages and we’re here to break them down.

Lifespan and Usability

Lithium battery banks can be expensive, and can cost almost three times as much as AGM batteries. With the expense comes a much longer lifespan that makes them work the money. Studies on lithium batteries have shown that they last for more than 2500 cycles, with some showing that the battery is still delivering 75 percent of its capacity at that time. AGM batteries typically only last for 500-1000 cycles which makes the cost worth it for lithium. If you factor in replacement costs, it makes complete sense to use lithium batteries over AGM.

Another benefit to using lithium batteries is that they can regularly discharge 80 percent of their rated capacity. You get more amp hours of charge, nearly twice as much as AGM.

Voltage

On most lead-acid batteries, when the charge level decreases so does the voltage. Similar to when the batteries are low in a flashlight, and it’s no longer putting out a bright light. This doesn’t happen to lithium batteries. When the battery is at 20 percent it will still be putting out the same voltage as when it’s at 80 percent.

Charging

Lithium batteries also don’t need a absorption phase to finish charging, which means they’re easy to charge. It doesn’t take long to charge them to full capacity. If your charger is strong enough, you can charge your batteries in as little as half an hour. If you’re into being off the grid, this means you’ll need to use your generator less, so that you can use solar power more.

Lithium batteries are also better at storing power. They can charge at nearly 100 percent efficiency, which is nearly 15 percent higher than most lead acid batteries. If you’re completely solar, and trying to use every hour of sunlight possible, this really comes in handy. Technically, every second of sunshine you can collect will result in power stored in your battery bank, if you’re using lithium.

Weight

Another added benefit of lithium batteries is that they weigh less. A lithium battery is capable of storing almost 3.6 times more usable amp hours than an AGM battery, that is the same weight. Not only will you be capable of storing more power, but you’ll get better mpg in your solar equipped RV.

At AM Solar we could go on about the various benefits of using lithium batteries in your DIY Solar RV.

Get Outside with Solar for RV

DIY Solar.jpg

While you may love getting outdoors, and traveling to places you’ve never been, a noisy campground can ruin it. While you love your RV, you might be looking for a way to get off the grid, and away from the crowded and noisy campground hookups. If you’ve ever thought about getting your RV equipped for solar power, there’s no time like the present.

Go Anywhere

If you’ve ever considered going solar, you might want to think about it more seriously. With a solar RV kit, it’s not too complicated to outfit your RV to go anywhere. Solar RVs don’t need noisy generators either, if you ration your energy and plan accordingly. With solar power, you won’t need a hookup either, so you can take your RV anywhere, as long as you can legally park overnight.

Benefits of Solar

When your RV is outfitted with solar panels, your panels supply poser to your RV batteries. The Lithium Solar Batteries store that energy until you’re ready to use it. If you install solar panels on your RV, it’s easier than using a self-charging battery system.

Energy

It’s important to know that it does take time to collect solar energy. You will have to plan for your usage. You won’t be able to roll into a campsite, or overnight parking and turn on your stove, or run appliances. You’ll have to plan ahead, and get to a site early so you can spend time collecting the energy that you’ll need to cook dinner and shower.

There are also solar calculators that you can use to factor your solar usage. You can figure out if you have enough power to cook dinner, shower and use a laptop for an hour. Or if you’ll have to choose between the three.

Once you go solar with a Solar RV Kit, there are endless solar appliances you can transition over to. Everything from stoves, flashlights, showers, headlamps and more are now available in solar models.

Get outside

If you’re looking for an easier way to get out and not be tied to campgrounds or hookups, solar is the way to go. Check out AM Solar, and ask them about installing solar panels on RVs. They can help you outfit your RV with solar panels, and help you get free of campground hook up restrictions. With a solar equipped RV you can set up camp anywhere, and enjoy the freedom of solar.

8/4/17 – 2018 Airstream Classic, 33’

This is the most solar power we have ever installed on an Airstream.  Our client will be able to run their residential refrigerator and even an air conditioner for a few hours at a time.  This is the gold standard for an Airstream power system upgrade and the artistry and technical know-how demonstrated on this job are why AM Solar is typically booked out four months in advance.

Join Roger as he replaces his batteries

Roger, a full time RVer and AM Solar Partner, just proved how you can get seven years out of AGM batteries if you take good care of them with quality chargers.  Last weekend he replaced his four Lifeline GPL-6CT (6V 300Ah AGM) batteries with a new batch.  He has a custom battery tray made by our neighbor (Commercial Metals) for his rig, a 2005 R-Vision Trail-Lite 235S B+ (24'), that enables him to slide out the majority of his 400+lb system with a forklift.  This clever design makes system maintenance much easier (assuming he has access to a forklift).

7/31/17 – 2017 Airstream Grand Tour, 24’

Smaller RVs, like this Airstream Grand Tour, can provide some challenges when it comes to finding enough room to install all the necessary components without taking up too much of our client’s storage space. For this client, we were able to install the vast majority of their system underneath their couch (not the solar panels though), minimizing the footprint of the system.  The Battery Management System we installed is removable, which can make upgrading much easier.

The Rising Popularity of Solar RVs

Off Grid Solar.jpg

With the rising real estate market, and the growing popularity of tiny homes in the last few years, RV living has taken off. RV’s are easier to get your hands on than tiny homes, and they offer more ease of travel than some tiny homes. Lots of young families and young couples are moving toward RV living as an easier way to own a home. If you’re looking for a lower cost living, investing in a solar equipped RV might be the answer. While it takes money to outfit an RV with solar panels, it will save you money in the future, and it’s worth it.

RVs

Owning an RV has become quite popular. RV ownership is at an all-time high now, with middle-aged buyers representing the largest group of owners. Other young professionals are finding that selling off their possessions and moving into a smaller space, like an RV or tiny home, can be quite liberating.

Solar Equipped RVs

What could be more liberating than the freedom of RV solar panels? If you no longer, need to hook up to power at a campground, you can realistically set up camp anywhere, as long as it’s legal to park overnight.

Some solar RV outfitters have solar RV kits that make adding solar panels to your RV quite easy. Some places like, AM Solar, even offer installation services.

While the price of living in and owning an RV is much less than owning a home, it’s even less when you factor in what solar power can save you. Using solar power to run an RV takes some getting used to, as you don’t have endless energy to use. Depending on how much energy you collect and save, you’ll have to pick and choose what sort of appliances you can use and run on a daily basis.

Some sites offer solar calculators so you know how much power you’ll need to use for certain appliances. With some appliances you can figure out how many kilowatts per hour, per year they use. With some charge converters, they come with mobile apps, that will help you monitor how much power you’re collecting throughout the day.

Take Away

If you’ve been thinking about downsizing for a while, the RV life might be perfect for you. If you’re not entirely ready, try borrowing a friend’s RV or renting one to see how much you enjoy the lifestyle. If you’re ready to commit, it might be time to consider the benefits of a solar DIY RV.

Solar Panel Bypass Diodes: What they should and shouldn't do

What the diodes supposed to do:

Bypass diodes were designed for solar panels back when most solar arrays were constructed by feeding about a dozen series connected panels onto a grid-tied inverter.  The purpose of the diodes is to improve the way a series connected array performs under partial shade conditions.  When one cell or row of cells is shaded, the diode across that shaded section bypasses the underperforming cells, allowing the panel to maintain the same current as the other panels in the string.  By maintaining the same current, the shaded cell(s), column(s), row(s) or panel(s) to not reduce the output current of unshaded panels.  

Diode 1.png
Diode 2.png
Diode 3.png
Diode 4.png

When a section of a panel is bypassed, the panel output voltage is reduced.  This is fine for series connections because the power from the unshaded cells will contribute to the total power produced, but in a parallel connection, this power would be at a voltage that would be too low to charge a battery.

Where it can go wrong:

Sometimes when a solar panel is carelessly connected to a battery bank with reverse polarity, the diodes can burn out and become dead shorts.  When this happens, the open circuit voltage of the panel is reduced proportionally to how many diodes are shorted.  For example, if you are only measuring about 11V on your panel you probably have half of your diodes shorted.  If you are getting 0V, you have all of your diodes shorted.

 
Diode 5.png
Diode 6.png
 

The fix:

Since most of our installations use parallel connected panels, and since bypass diodes don't help the performance of parallel connected panels (and since you already voided your warranty by reversing the polarity on your panel) you can repair the panel by simply clipping the diodes out.

Remove the junction box cover.

Remove the junction box cover.

Clip one of the legs of the ruined diode and bend it away from the severed contact.

Clip one of the legs of the ruined diode and bend it away from the severed contact.

Clipping the damaged diode(s) should restore the panel back to full voltage.  Although it isn't necessary for parallel connected panels, you can buy replacement diodes and solder them back in.  But, before you do this, be sure to take a picture of the open junction box so you can see the way the diodes should be installed.  If the line at the end of the damaged diode is on the right side, your replacement diode better have it's line pointed to the right as well.  Diodes aren't like resistors, they have polarity and can be installed backwards.

 
If you need replacement diodes, I have a bag full of them.

6/23/2017 – 2006 Lazy Daze, 27’

These clients came to us with an existing solar system that they wanted to expand.  We were able to utilize a lot of their existing system by doing series/parallel connections on their roof, saving them some money on parts and labor.  They also requested a larger battery bank.  Their existing battery bay wasn’t large enough to accommodate the four additional AGM batteries we installed, so we put half of them inside the existing bay, and the other half in their coach underneath their dining room bench.  The additional 300W of solar power, and the added battery capacity will allow them to dry camp for a longer period of time.

This client’s RV was pre-wired by the manufacturer with 6-gauge cables, and an inverter.  We installed 960 watts of solar power, which is more than we would recommend for 6-gauge cable, so we had to take additional steps in order to make the system as efficient as possible.  With these under-sized cables, voltage would have been lost between the solar panels and the charge controller.  We installed the solar panels using series/parallel connections to increase the voltage, reducing the amount of voltage drop to less than 1%, which resulted in increased system performance.  This client will be able to run their residential refrigerator without using a generator or shore power.
