The Tesla battery: the final solution for a greener home? (Final Part)

Ok. We have analyzed all the benefits of this new battery in the last two previous articles but are they going to be marketed in Spain?


A long road ahead.

According to Forbes reports, the US government is making serious efforts in the production of renewable energy and Tesla battery fit perfectly.


Elsewhere in Europe the situation is more complex. In some countries like Germany and Holland it used what is known as a net balance. Instead of storing the energy captured by solar panels it is poured into the system and in return individuals receive a small bonus in the form of energy that can be used freely. That is, the system serves both for consumption as to reduce the final electricity bill. The power company, in return, receives energy produced by individuals.


In Spain the picture is much bleaker.

According to a Self consumption Royal Decree, which is not yet approved, the individual would have to pay a toll to use the grid for transporting the electricity. It sounds as absurd as it really is. In the background is simply the result of pressures from energy companies not to lose their piece of the pie.


While writing this article I have connected to www.teslamotors.com and they have started advertising the Powerwall Energy Storage for a Sustainable Home!!


This information below it has been obtained directly from their web.

According to Tesla the Powerwall is a home battery that charges using electricity generated from solar panels, or when utility rates are low, and powers your home in the evening. It also fortifies your home against power outages by providing a backup electricity supply. Automated, compact and simple to install, Powerwall offers independence from the utility grid and the security of an emergency backup.


The average home uses more electricity in the morning and evening than during the day when solar energy is plentiful. Without a home battery, excess solar energy is often sold to the power company and purchased back in the evening. This mismatch adds demand on power plants and increases carbon emissions. Powerwall bridges this gap between renewable energy supply and demand by making your home’s solar energy available to you when you need it.

  • Avoid Paying Peak Rates Power companies often charge a higher price for electricity during peak evening hours than overnight when demand is low. Powerwall  can store electricity when rates are low and power your home when rates are high.
  • Energy Security Powerwall automatically switches to battery power in the event of an electric company outage, bringing peace of mind to those who live in areas prone to storms or unreliable utility grids.
  • Powerwall comes in 10 kWh weekly cycle and 7 kWh daily cycle models. Both are guaranteed for ten years and are sufficient to power most homes during peak evening hours. Multiple batteries may be installed together for homes with greater energy need, up to 90 kWh total for the 10 kWh batteries and 63 kWh total for the 7 kWh batteries.

How it Works

Home solar installations consist of a solar panel, an electrical inverter, and now a home battery to store surplus solar energy for later use.


Solar panel

Installed in an array on your roof, solar panels convert sunlight into electricity.


Home battery

Powerwall stores surplus electricity generated from solar panels during the day or from the utility grid when rates are low.



Converts direct current electricity from solar panels or a home battery into the alternating current used by your home’s lights, appliances and devices.


Contained within Powerwall 's outdoor-rated enclosure is a rechargeable lithium-ion battery, a liquid thermal management system, a battery management system and a smart DC-DC converter for controlling power flow.


A new beginning for self produced home electricity!! Amen.
