Structure and contract adapted to my needs

What pergola or carport should I choose? How do I know what power is suitable for my needs?

Discover below how to calculate your solar needs in order to choose the design pergola that suits you!

To determine the photovoltaic power you need, simply take the power of your meter and divide it by 3.

In case of high electricity demand, you can divide the power of your meter by 2 instead of dividing it by 3.

Example: if your meter is 12 Kva (power of your meter), you will need a minimum power of 4 Kwc.

In this case, our 4.05 Kwc butterfly pergola will be perfect for you. But if you want to opt for a larger model, it’s not a problem because it will allow you to sell or store your surplus.

Here are examples of recommended powers based on your usage:

  • House with only heating: a 4.05 Kwc pergola will be suitable without any problem
  • House with heating + heated pool, electric car, air conditioning, or other: ideal 6.48 Kwc
  • The carport or 8.10 butterfly pergola will allow you to store or sell your surplus because the more powerful the installation, the more production there will be.

What contract should I choose for my solar pergola or carport?

Your choice should take into account the following information:

Simple self-consumption:

You consume your production, but be careful, with this option, you cannot exceed a production of 3Kva. This option allows you not to have to make a prior declaration to your town hall. However, it is not the most interesting option from a solar point of view. It will require an additional regulator on the structure to control the consumption of your design canopy and not exceed the return on the network of more than 3kva.

 

Self-consumption with surplus sales::

This contract is the ideal contract for a private solar pergola or carport. With this option, you can accumulate Kwh that you will then use for your own consumption. If you produce more Kwh than you need, they will be stored or sold. It is essential that your structure be connected by a QualiPV or RGE installer.

  • Option 1: Storage: you choose a connection with a “virtual battery”, in this case, all the surplus will be stored to be automatically reused in the months when you produce less than your needs.

  • Option 2: Sale: to be able to sell the surplus, it is mandatory to have your installation connected by a QualiPV or RGE installer.

Total resale:

With this contract, you will not consume any accumulated Kwh, but you will sell everything that your structure generates.

The contract for your solar pergola will depend on your meter

  Single-phase electric meter :

– If you do not sell surplus power and only consume it, you cannot exceed 3 Kva of power sent back to the grid. In this case, you will need an additional regulator to block the sending of more than 3Kva to the grid.

– If you choose a contract for self-consumption with surplus sales (which we recommend), you can go up to 6 Kva without any problems. In this case, our Papillon design solar shades of 4.08 Kwc and 6.48 Kwc are perfect.

– If you want to opt for a large Papillon solar shade of 8.10 Kwc, it is possible but you must have a regulator that will regulate and not send more than 6Kva to the grid.

    Three-phase electric meter:

    – With a three-phase meter, you can opt for an 8.10Kwc solar shade without any problems.”

    Which supplier to choose for my solar pergola?

    There are different suppliers offering different services. Here are 3 suppliers and their main differences.

    Other suppliers exist such as Urban Solar, JPME and others. Here is an example:

    Urban Solar : 

    • Two contracts are possible: surplus resale or battery storage.

      – in the case of a contract with surplus resale, you do not have to change your current supplier
      – In the case of a contract with battery storage, Urban Solar will become your electricity supplier. They buy the surplus produced twice a year.

    • No time commitment, you can change your contract whenever you want, but you will not be able to go back to EDF OA
