New approaches for small RV’s. PHOTOVOLTAIC FACTS After I introduced Semi Flexible Solar Panels in my previous post, questions remain about the performance of these new semi flexible modules. SOLAR PANEL TYPES Rigid Residential Flexible Amorphous Thin Film Semi Flexible average cost per watt 1 $ 0.80-2.00 $ 1.50 $ 2.00-7.00 low light performance average… Continue reading Solar Panel Guide (2)

Solar Panel Guide (1)
New approaches for small RV’s. THIS DECADE HAS SEEN MANY ADVANCES IN SOLAR PANEL RESEARCH, WITH THE DEVELOPMENT OF A WIDE ARRAY OF NEW MATERIALS, WHICH IS CHANGING RV LIFE. Less important to the big rigs, that have large, flat roofs to support a large numbers of panels, the smaller Class B RV’s and Cargo… Continue reading Solar Panel Guide (1)
12V Fan Switch
Recently a fan was installed to cool the solar components, like controller, battery charger, etc. As it is not necessary to run the fan continuously, a switch can regulate its use. Radio Shack sells this 12V switch with a ground (+), a power (-) and a accessory spade. Right now there is a wire running… Continue reading 12V Fan Switch
12V Cooling Fan
The compartment under the bed that will hold the charger, controller, inverter, etc. is a small enclosure and needs some form of cooling. I choose a 5” computer fan with thermal control, that automatically adjusts its speed as the temperature rises. Other considerations were low noise level (<18dB), high airflow volume (up to 42cfm) and… Continue reading 12V Cooling Fan
Wiring(4)
Having batteries, doesn’t automatically mean access to 12V. Thus, two access points are planned in the van. One 12V socket is located at the solar components (controller, charger, inverter, etc.) compartment, under the bed. It’s immediately next to the pull-out shelf and serves to power my laptop. 12V Power Socket It’s a standard 12V… Continue reading Wiring(4)

Continuing with the wiring of the van, gives me the opportunity to search for and order some of the materials, needed in the coming weeks. My list currently consists of wire connectors, heat shrink, 12V outlets and power inlet. I still haven’t found decent and affordable 12V LED light fixtures either. LED Lights Several… Continue reading Wiring (2)
Wiring
While working on the multi-use cabinet, I started with some of the wiring. Before I can continue building new cabinets, the majority of the electrical wiring has to be installed. Battery Monitor The monitor will be located on the wall next to the side doors and connected to the batteries with 4 small… Continue reading Wiring
Power Monitoring
The introduction to off-grid power (upgrading to off-grid power, power storage and power generation) is concluded with a post about monitoring and maintenance. With all this knowledge we can finally begin with the installation. Daily monitoring the off-grid system is crucial for the longevity of the system. Maintaining a sufficient battery charge will extend… Continue reading Power Monitoring
Power Generation
After upgrading to off-grid power and power storage, this post elaborates on the available power generating tools for a small RV. The electrical calculations are comprised into a detailed schematic overview, that serves as the basis for the installation. Alternator The extra power from the alternator can be directed to the battery bank, to… Continue reading Power Generation
