Green energy. A term we hear a lot these days, and for good reason. Climate change is accelerating, and it’s crucial that we reduce our carbon emissions by switching to cleaner, more sustainable energy sources.

As an active member of Powertec, a French organization that designs, manufactures and distributes a professional range of portable solar chargers, I’m passionate about helping people make this transition. One solution I’ve found particularly effective is the installation of our solar panel kits for self-consumption.

What is green energy?

Green energy, also known as renewable energy, is energy generated from inexhaustible natural sources. These sources include the sun, wind, water and the heat of the Earth itself.

Green energy is of vital importance to our future. As well as helping to reduce our dependence on fossil fuels, it can help stimulate the economy and create jobs, while reducing energy costs in the long term.

What is solar self-consumption ?

Solar self-consumption is a concept that involves producing and consuming your own energy from the sun. This is usually achieved by installing solar panels on the roof or other surfaces exposed to the sun. At Powertec, we offer solar panel kits for self-consumption that are designed to be easy to install and use.

The advantages of solar self-consumption

Solar self-consumption has many advantages. It reduces carbon emissions, saves on energy bills, and gives you greater energy independence. In addition to these benefits, using Powertec’s solar panel kits means you can charge your portable electronic devices wherever you are, thanks to the sun’s free, renewable energy.

The impact of Powertec’s self-consumption solar panel kits

As a professional green energy investor, I’ve seen first-hand the positive impact that Powertec’s solar panel kits can have.

Not only do they help reduce electricity bills and contribute to the fight against climate change, they can also be used to charge portable electronic devices in an environmentally-friendly way.


At Powertec, we firmly believe that the transition to green energy is not only necessary, but beneficial for everyone.

By investing in our solar panel kits for self-consumption, you can not only reduce your electricity bills and become more energy independent, but also actively participate in the fight against climate change. It’s a step towards a greener, more sustainable future, and we’re delighted to help you take that step.


1. Which solar panel for an autonomous house?

Here are a few suggestions to help you make your choice:

  • Monocrystalline solar panels: These are the most efficient solar panels, as they are made from a single silicon crystal. They are also the most expensive. They’re a good option if you have a limited surface area for installation.
  • Polycrystalline solar panels: These are less expensive than monocrystalline panels, but have a slightly lower yield. They are a good option if you have plenty of space for installation.
  • Thin-film solar panels: These are less efficient than monocrystalline and polycrystalline panels, but are more flexible and lighter. They’re a good option if you’re on a budget, or if you need solar panels that can be installed on uneven surfaces.

2. Are Powertec’s self-consumption solar panel kits cost-effective?

Yes, although the initial investment can be significant, the savings on electricity bills and the ability to charge your electronic devices free of charge usually pay for themselves within a few years.

3. Do Powertec’s self-consumption solar panel kits work in the event of a power cut?

Yes, if you have an energy storage battery. Without a battery, the system will be disconnected from the grid for safety reasons in the event of a power failure.

4. Do Powertec’s self-consumption solar panel kits require a lot of maintenance?

No, our solar panels are low-maintenance. Occasional cleaning to remove dust and dirt may be necessary, but in general they are designed to be as maintenance-free as possible.

5. What is the maximum power for self-consumption?

It all depends on how much sunlight your home receives, how much space you have, and the type of system you use.

The maximum power of a self-consumption system depends on a number of factors, including the size of your roof, the number of solar panels you can install, the orientation of your roof in relation to the sun, and the region in which you live.

In France, for example, the regulatory framework allows private individuals to install photovoltaic self-consumption systems of up to 100 kWp (kilowatts peak). This is a considerable amount of energy, and would be sufficient for most households and even some types of small business.

However, it’s important to note that in practice, most domestic installations are much smaller, typically between 3 and 9 kWp. A 3 kWp installation can produce around 3,400 kWh per year, which is enough to cover around half the electricity needs of an average household.
