Take the panel with you

Solar Panels are getting cheaper every day, so this idea might convince you less today than it could have some time ago…

Anyway, suppose you have bought yourself one 300 W solar panel for your flat. In fact you found a smart orientation that covers your “base load” for the fridge and all the stand-by consumption and also lowers your consumption once you arrive home. It happens you have a e-bike that is prepared for you to plug your panel, for your daily commuting, keeping your battery fine or even charging while you are working. Additionally, you own an Electric Vehicle. During the week-ends, you can dock your panel for the journey and lower your consumption. And it happens that you are as wealthy as to have a second house in the forest, which is off-grid, so you use the battery of the Electric Vehicle for your consumption and you also plug your panel when you arrive.

Panel cycle

This is just an example of maximizing the asset utilization of a panel, for house self-consumption in two locations, and also for mobility. This will not be the case for most people, of course. Besides, regulatory frameworks may promote the use of the panel to feed the grid when it would be underused only for self-consumption and could be connected elsewhere for other purposes. Anyhow, the point of having portable generation opens more possibilities for generating one’s own energy, in this case at home and also for transportation. It is also an application for extending the access to electricity in developing countries.

In fact, if a person consumes (as it is the case in Spain) 3487 kWh/year of electricity and 9908 kWh of total energy at the home, together with 12000 km/year of driving, which can be calculated as 2400 kWh (with an EV doing 20 kWh/100 km) it makes a total of 12308 kWh. In order to source this with solar PV, he would need approximately 6 kW of solar panels working 2000 equivalent hours. These 20 solar panels he cannot take around with him that easily. For the moment…

P.S.: Allow me to include the crowded house video as the song I thought about while writing…

Hot. Classic. ConvertEV

The beauty of many classics is appreciated by almost anyone. Even a 5 year-old child has no problem admiring the lines of an old sportscar…


To keep these hot rides running, when the old engine is hardly repairable, there is an option; to make them electric.

There are at the moment some start-ups focused in EV conversion, as Zelectric motors, specialized in converting classics to electric, for example the VW Bug. Another example are the conversion kits from EV West, allowing individuals to convert the vehicles.

Here in Spain we have Jofemar’s Hidronew Project. And they have proven in EV competitions that their converted vehicles are fast.


Although with an electric drivetrain these models are more environmental friendly and have the old beauty and the new efficiency, it’s true that losing the original engine and noise is like tearing the soul of these cars. That’s why i’m in favor of converting the vehicles when the original engine can no longer be repaired as original.


As car workshops get used to EV maintenance and repair (simpler than internal combustion drivetrains) the conversions will grow, adding EV units by reusing old cars instead of building from scratch.

I’m sure this is going to get more and more common, converting an old car will get less expensive and it may become the cheapest (and coolest) way of owning an EV.

El albor de las lumilineras

Ya hemos oido hablar de las electrolineras, de las ferrolineras… toca el turno de las luminileras!

El concepto es simple, los vehículos eléctricos podrán hacer trayectos largos siempre y cuando puedan hacer cargas rápidas durante el camino. Esto no tiene por qué ser en una gasolinera, como hoy las conocemos, cualquier “bar de carretera” con suministro eléctrico puede ser un gestor de carga. Si tenemos en cuenta que ya tienen experiencia con grandes luminosos eléctricos, enchufar un coche no les resultará muy complicado.

Entrevistamos a Dazo Lupanâr*, ciudano búlgaro, afincado en nuestro país y que regenta un burdel de carretera. Nos comenta con firmeza “Vivimos tiempos difíciles, hay que innovar o morir. Ya implantamos el 2×1 o el happy hour para atraer clientes, pero se requiere ir un paso más allá, un paso tecnológico. La movilidad eléctrica es una gran oportunidad, los 15 minutos que tarda en cargar un coche pueden servir para que el conductor descarge, o bien que salga con las pilas cargaditas, no sé si me explico…”

La carga de vehículos sería un reclamo más, como un servicio adicional. “Como cuando en verano las chicas hacen lavado a mano de coches en bikini, una pizca de marketing”

Al preguntarle sobre el tipo de clientela que atraerá on este servicio nos confesa “los tipos ecológicos son buenos clientes, y además tratan bien a las chicas, aunque dentro de nada todos tendremos coche eléctrico…” dice, tras lo cual mira con nostalgia al ferrari con el que se mueve por su territorio.

Su próximo negocio, para el que está acumulando capital en grandes fajos, es también de alta tecnología y altos vuelos, “Lupan-airlines“. El reclamo a volar con esta compañía es simple… “La clave está en la experiencia de vuelo, no simplemente trasladarse rápido y al mínimo coste. El paraiso bien puede estar a diez mil metros” apostilla con un guiño. Pero esa es otra historia…
