Calentador de agua solar sin presión simple

Calentador de agua solar sin presión

En esta configuración, el sistema se utiliza como “Añadir” a un existente agua sistema con caldera.
Si bien no puede correr alrededor de temperaturas heladas o por debajo ( 0° C ), es una forma fácil y cómoda de producir agua caliente.

El colector / tanque se montó en vigas de madera de 8 cm X 8 cm con los tornillos adecuados..
Para un fácil acceso, una posición en un “medio techo” fue elegido. La instalación tomó alrededor de un día. (con algunas modificaciones en el marco de soporte).
La instalación de agua es paralela a la caldera de agua caliente existente..

Como conexión tubo semiflexible de 16 mm(PEX – AL Henco) was choosen using compression fittings.

The device is an unpressurized tank (160Modelo L con 18 tubos de vacio) con serpentín intercambiador de calor. En general, el sistema no necesita mucho espacio., the installation is pretty straight forward and the price is relative low.

Ventajas:

-No necesita mucho espacio, construcción muy compacta.
-Dado que el tanque no tiene presión, tiene una protección básica contra sobrecalentamiento. (efecto de enfriamiento por evaporación)
-Fácil montaje / plomada
-Puede ir mal durante 2 días con el tanque de 160 litros y 3 la gente lo usa (sin que el sol brille)
-Acerca de 20 año de esperanza de vida
-Fácil de integrar en los sistemas de calefacción de agua caliente existentes
-Mayor eficiencia en comparación con los modelos heatpiped
-Necesita unas 6 horas de buen sol para calentarlo
-Mejor eficiencia de bajo brillo en comparación con el calentador térmico de panel plano

Desventajas:

-no soporta temperaturas bajo cero(tiene que ser drenado)
-el agua dura puede causar algunos problemas en el futuro

How to add a OffGrid Solar-System to a house that already has grid-power

How to add a OffGrid Solar-System to a house that already has grid-power ?

Situation

The following situation is a very common occurrence. It’s one we’ve had come up in the community a lot, and for most people in a semi urban environment this is the most likely scenario: The House already has a grid connection. However you want solar to have the option to be self sufficient if need be, as well as saving considerably on electricity costs.

Solution

The most easy solution for this is a OffGrid Island setup with a grid input connection. Basically it means to build a self-sufficient solar system with a batería, using a OffGrid-AllinOne-Units to then connect the existing grid power to the system. This also allows for an easy connection of a gasoline generator.

Types of OffGrid-AllinOne-Units

There is 2 main types of OffGrid-AllinOne-Units.
OffGrid Island Inverters with grid input option and Hybrid Inverters.

” While both systems aim to maximize the use of solar energy, their main difference lies in the way they handle storage of energy. In an Off-Grid Solar System, the inverter will attempt to use solar energy for “self-consumption” by sending it directly to load or use it to charge battery. If there’s any excess solar power, nothing will be done as there’s simply no more room for energy storage.
On the other hand, a Hybrid Solar System will still attempt to maximize the use of energy through load or charging battery, and any excess power will simply be “fed” to the grid, which act as a nearly limitless power storage. “(1)

Installation – Legal

In many countries the injection of solar power into the grid using a hybrid inverter will require some sort of paperworks and legal permits. Make sure to double check your legal situation before installing a hybrid inverter.

Going with a OffGrid Island setup with a grid input connection is more often the easiest solution, as one does not need to touch the existing house electric to install and operate it. The grid input can be done with a normal plug. One simply plugs the OffGrid Island setup into the existing electric system of the house like any other household device.

Using one of these devices also makes it easy to have a seamless fallback to grid power in case of no solar power present and the battery being empty. Most OffGrid Island Inverters will have detailed configuration options on primary power source, fallback source and such.

Cabine – Camp Decadence

Camp Decadence

Ubicación: North-Central United States – Climate Zone 7

All framing is 16 inch on center. Main floor joists are 2×10 inches, walls and 2nd floor joists are 2×6, and roof rafters are 2×8. Roof pitch is 12/12 (45º). Everything is insulated with R-19 fiberglass.

Construction began in 2012. Total cost so far is around 13,000 USD and completion should top out around 15k. This includes a small amount for labor, specifically installing most windows, the roof, and the house wrap in 2013. It also includes some second-hand materiales that reduced costs.

Cabine:

• Total Size : 400 ft² usable space
• 12×16 main room
• 12×6 covered porch
• 12×8 loft bedrooms (2) upstairs with…
• 12×5 landing/hall between

Sistema de poder
400 Vatio Solar Panels
2x AGM Lead Acid Las pilas at 24 Voltio : 35 Ah
60A MPPT charge controller
1,6 kW Inverter

Calefacción
14 kW Stove for wood logs or coalbrickets. (can be leveld down to 3kW )

Agua
Wash agua is sourced from snow in winter, rain gutters/barrels in summer, and an on-property creek when those fail.
Drinking/cooking water is sourced in town and brought in jugs.
