Your Sunology solar stations produce more energy than you consume, and you are desperate to see it go free in the street? Good news: you will be able to resell it to ekwateur, thanks to a virtual battery system!
ekwateur buys your surplus production!
ekwateur is an alternative electricity supplier, which I had already told you about a few years ago, since I was myself a customer of this green electricity supplier. It was also one of the first to launch its own solar station, via a group order, in which I had also participated, and which had allowed me to offer you a test.
Today this green electricity supplier announces its partnership with Sunology: indeed, if you have an ekwateur or Sunology solar station, it becomes possible to resell your surplus production! And that's great news, because until now, solar station owners couldn't resell their production, and simply saw it go free in the street and to neighbors (who paid for it to their electricity supplier, of course…).
This is made possible thanks to the principle of the virtual battery. As its name suggests, it is completely virtual. Here, no battery to plug in at home. In fact, the surplus electricity produced will be automatically recorded by ekwateur, and bought back at the rate of 8.3 cents per kWh.
This kitty collected thanks to the surplus production will be deducted from the monthly consumption bill.
For example:
- you have consumed 500kWh over the month, at €0.21 per kWh, this makes a bill of €105
- you have had an overproduction of 30kWh over the month, bought back at €0.083 per kWh, you have a kitty of €2.49
- your consumption bill will then be reduced by €2.49, i.e. €105 – €2.49 = €102.51
The conditions to benefit from it
To benefit from it, you will of course need to have one or more Sunology or ekwateur solar stations. And have noticed a regular overproduction of your installation. Normally if you have correctly sized your need when purchasing, you should not have any, or very few.
You will also need to be, or become, an ekwateur customer for your electricity contract. If you are on the regulated rate with EDF, the rates are quite similar, with a kWh price at €0.2096 currently. You can do your simulation here.

Finally, you will have to pay €59 for the management of the access and operation contract with the Enedis agency.
Is it interesting?
At the proposed buy-back rate, unless you have really oversized your installation, this will only be a few euros to deduct from the electricity bill each month. It is not huge, but it is always something, and your production is not injected free of charge into the general network. It is therefore fully exploited.
To make this more attractive, the surplus buy-back subscription, normally billed at €1.50/month, is offered here for two years.
And if you are a new ekwateur customer, it offers you 150kWh of free electricity, upon subscription, the equivalent of around thirty euros, which somewhat offsets the cost of the connection request to Enedis.
In other words, subscribing to this service to take advantage of the virtual battery does not really incur a cost, but can on the contrary earn you a few euros to compensate for this solar energy that you do not use when it is produced. It is always good to take!
Of course, the ideal is to consume your own production at 100%, which avoids consuming kWh billed at more than 20 cents while reselling the surplus at 8 cents. To do this, it is necessary to opt for a solar station power equivalent to its electrical heel. We have already explained it many times: the goal of these solar stations is to erase the electrical heel, that is to say the consumption of devices that are always running at home, whether you are present or not. The goal is in no way to power the entire home. However, many users voluntarily oversize their installation, to compensate for the drop in production during the winter. Thus, in winter, they erase their entire electrical heel, despite a significantly degraded production during this period. But suddenly, in the summer, this results in overproduction compared to their normal consumption. From May to September, overproduction can be significant, and it can indeed be interesting to be able to resell it to reduce your overall electricity bill a little.
For my part, my production is already optimized thanks to the battery kit from
Zendure , which I adapted to my Sunology panels. But it is true that the investment is difficult to make profitable if you have a very small overproduction. In this case, the virtual battery offered here by Sunology and ekwateur is a very good option!And you, what do you think?
