Is your RURAL home ISOLATED from the electric line? Small renewable energy are only profitable off-grid, as they have small size, need accumulation and can not be simultanousely from different sources.Do you doubt to connect your FARM to the MAINS? The electric line is more cost competitive in kWh per variety in the mix of …

¿Tu CASA RURAL esta AISLADA de la linea electrica? ¿Dudas si conectar tu EXPLOTACION AGRARIA a la RED? Las pequeñas energias renovables solo son rentables cuando estas desconectado, ya que no tienen las tres ventajas de la linea eléctrica (variedad, tamaño, necesidad de acumulacion). La linea electrica es mas competitiva en coste de kWh por variedad en el …
Do you want to SAVE stationary batteries in your remote RURAL housing?
In this last post # 10, I summarize the different ways to save on electric accumulators of a photovoltaic or mini-wind system that I have explained in previous posts in this series:
Stationary batteries are really necessary in any system isolated from the mains. Absolutely. But when the accumulation needs are high, investment in batteries is unsustainable. Therefore we must seek alternatives to supplement the storage of energy.
The cheapest electricity is which is not consumed. You should review what are the appliances, equipment, machinery, etc. reasonable to have or not in an isolated home. Once you have choosen the essential minimum, look to be efficient electrically, with very low consumption. Your battery will thank you.
A small diesel generator to complement a stationary battery bank can be the most realistic option to reduce the costs of investment in batteries. You just have to know how to manage the load periods to give more priority to renewable energy and spend a minimum of oil.
The capacity of production (photovoltaic or small wind generation) is more important than storage capacity (storage batteries). If your budget is very restricted, it is better to prioritize the generation than accumulation.
An alternative energy storage systems of medium size is a closed loop of water. First step: the water is pumped by a Solar PV to a higher deposit. Second step: Water falls through a micro-hydraulic turbine to generate electricity to charge the batteries.
A mini wind power system can trigger an air compressor in a large air-storage tank. Electricity can be generated subsequently again with an air motor. There are few experiences, but is feasible in rural areas, plenty of space available.
An electrolysis in a rural area that can generate hydrogen from renewable energies is the first part of the system. The second part is a fuel cell fed with hydrogen and oxygen to generate electricity and steam. It may be the technology of the future, although currently still under development to lower costs.
Low cost batteries with sodium salts may be in the future an inexpensive system of direct accumulation of electricity. Batteries are currently still very large working at high temperatures.
A large heavy wheel at high speed can build up energy that can be transformed later into electricity. Also there are a variety of systems to store energy or electricity in development.
To conclude this series of posts dedicated to saving solar batteries I remember the following priorities:
A) Savings and energy efficiency in the isolated systems. Generate and accumulate the electricity itself is expensive, so spend what is really basic.
B) Find a good professional with experience in Solar PV in your area to help you correctly size the system and stationary batteries.
Dou you think you can save batteries with any of these solutions? What experience do you have? Thanks for posting your opinion!
¿Las BATERIAS SOLARES de tu GRANJA se quedan sin electricidad? ¿Quieres AHORRAR baterias estacionarias en tu vivienda RURAL AISLADA? En este ultimo post nº 10, resumo las diferentes maneras de ahorrar en acumuladores electricos de un sistema fotovoltaico o mini-eolico que he explicado en los posts de esta serie: 1.- Los Acumuladores Solares son caros. Las baterías estacionarias …
Do you work in a FARM or live in a isolated COTTAGE? How to SAVE BATTERIES in your solar or wind power system? Pumping water in a closed circuit, accumulating energy and generating afterwards electricity with micro-hydro.
