Solar power gives you power from the sun. Building your solar system for your particular needs is the goal. Here are some tips from Wicked Cool Vans.

What items will you need power for? How much sun where you will be traveling? Do you have a maximum price you are able to spend on your solar system? Are you going to depend entirely on solar power? Will there be a back up plan for power?

Food for thought. Will you be shopping for food often? If you need to keep food cold or frozen you will need a place to store such items. A refrigerator is most likely an item you want in your van. Refrigerators draw a lot of power. The option of a smaller 12 volt refrigerator is your best choice. The 12v systems can keep your items cold or even frozen. Having a small refrigerator can let you stay away from civilization longer.

The unit above is calculated at 45 watts of power. The motor only kicks on when the temperature falls below your settings. We find it a perfect unit for our needs and solar system size.

There are other options for cooling your food. We recommend one like this cooler style refrigerator. Cold air sinks. With the units that have a door on the front tend to loose the cold air faster. This makes your unit turn on more often. In turn this uses more power and is less efficient.

Here are some other refrigerators we recommend:

Dometic CRX-65 75500.000.21 12/24 Volt DC Compressor Black Refrigerator and Freezer https://amzn.to/39cLxex

Norcold Nr740Bb Dc Refrigerator 1.7 Cu Ft, 20-1/2″ x 18-1/2″ x 21-1/16″, Black https://amzn.to/3d68AZJ

Dometic CD-50 (DC only) Drawer Refrigerator 47-Liter Capacity and Removable Freezer https://amzn.to/3d4lNCk

Other power items we use are water pumps, water heaters, USB ports, lights, heaters, cooling systems and fans. All of these items can be found with 12 volt power options.

The items require a draw off of your batteries. The wattage they use must be added up to find out what amperage you will need for your system. After you come to that number you must choose your batteries. Lithium batteries or sealed gel batteries? What will your budget allow? We personally have sealed gel batteries in our Wicked Cool Van. We suggest to our clients to go with the lithium from the start if your budget allows.

After you find your wattage needs you will be able to pick your solar panels. We like the Renogy 100 Watt 12 Volt Monocrystalline Solar Panel, Compact Design 42.2 X 19.6 X 1.38 in, High Efficiency Module PV Power for Battery Charging Boat, Caravan, RV and Any Other Off Grid Applications https://amzn.to/31dG0jv we have four on our van.

Size of the panels and your roof top application can determine how many you can fit. We have four 100w panels on our van. More could fit if we needed extra charging power. The Renogy panels are a good size for multiple configurations.

Renogy Rover 40 Amp 12V/24V DC Input MPPT Solar Charge Controller Auto Parameter Adjustable LCD Display Solar Panel Regulator fit for Gel Sealed Flooded and Lithium Battery https://amzn.to/3vYgzAv is needed to connect your solar panels to your batteries and other equipment.

Renogy 3000W 12V Pure Sine Wave Inverter 3000 Watt Solar Power Battery Converter 12VDC to 120Vac ETL Listed https://amzn.to/3tTkDjA is needed if you intend on using items that require a 120v plug. The inverter allows your solar to power most any lower wattage plug in items. If you intend to charge a computer, plug in a cooktop or run a water heater an inverter is needed.

Multiple breakers and fuses are needed in any system. This allows the proper amount of energy through your cables. If the cable is overloaded the breakers or fuses with break/stop. Helping your system perform in a safe manner.

We find staying parked in the sun gives us enough power for our needs. This way we are only drawing excess overnight from our batteries. Recharging again in the morning.
