Is your FARM DISCONNECTED from the grid? Would you like to have ELECTRICITY with RENEWABLE ENERGY? WIND POWER can be your solution! What Small Wind Turbines are? A wind turbine converts wind energy into electricity. The kinetic energy of the wind is captured through the windmill blades and transferred to a rotor normally connected to a …
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 …
Are your SOLAR BATTERIES run out of electricity in your FARM?
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:
1. – Solar Batteries are expensive.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.
2. – Saving and Energy Efficiency.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.
3. – Fuel generatorA 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.
4. – Increase Photovoltaic or Wind capacityThe 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.
5. – Micro-hydraulic closed circuitAn 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.
6. – Compressed airA 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.
7. – Hydrogen and Fuel CellsAn 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.
8. – Sodium Accumulators?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.
9. – Flywheel and other systemsA 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!

Do you want to STORE ENERGY on your FARM? Don’t you want to spend too much on BATTERIES? Will HYDROGEN FUEL CELLS be the solution? Future technology for Rural areas I’ll say it clear. Hydrogen fuel cells are NOT currently a viable economic solution. But it will be in the future, when electrolysis and fuel cell technologies …
Do yo live in a RURAL HOUSE with a wind generator to produce electricity? Have you met EMPTY BATTERIES after some days without wind? How to fix it investing the minimal quantity of batteries of accumulation? COMPRESSED AIR can be your solution. (Source: http://www.theengineer.co.uk) Compressed Air as Energy Storage Your own wind turbine supplies electricity when the …
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. Solar PV or small wind power to raise water to a higher level We have an installation with photovoltaic modules or …
Higher accumulation or higher generation? What can YOU do to spend less on batteries accumulation? For example, we need to invest for four days autonomy without sun: Is it preferable to invest a lot in batteries to be parcially full, or is it better to have an adjusted Amp/h accumulation, but starting with 100% charge …
