Frequently Asked Questions

Clear answers to frequently asked questions.

General

How can I be sure that I can trust you?

At Energia, we place great importance on transparency, technical quality, and strict compliance with regulatory standards.

We only install high-performance, recognized equipment: Bourgeois Global BVBF TOPCon 500 W panels, MyLight150 Quartz Heterojunction BVBF 500 W, Bourgeois Global micro-inverters, Solplanet hybrid inverters, and MyLight150 virtual battery solutions.

Our technicians are trained, certified, and work in full compliance with current standards (e.g., Certisolis PPE2 V2, safety at height, full PPE).

We take care of all the administrative procedures: preliminary declaration to the town hall, Enedis connection file, Consuel certificate, and electrical compliance.

You can consult our certifications, guarantees, customer reviews, and feedback at any time.

With Energia, you are guaranteed a reliable, compliant, and sustainable installation.

Can I contact the technician who will be coming to my home directly?

Yes, absolutely. Before the work begins, our site coordinator will introduce you to the technician in charge, explain their qualifications, and outline the planned schedule. You can speak with them directly to confirm the practical details.
And of course, our support team is available at any time if you have any questions.

What is the average time between quote approval and installation?

The timeframe depends on several factors: technical inspection, any necessary permits, connection, availability of contractors. As a general rule, for a standard self-consumption installation, this can vary from a few weeks to a few months. Once signed, we will provide you with a clear schedule.

What savings can I expect with your solar solution?

Savings vary depending on a number of factors: roof orientation and pitch, consumption habits, installed capacity, but also the quality of the equipment chosen (panels, inverters, micro-inverters) and the type of battery (physical or virtual).
Depending on the configuration, your bill could be reduced by 50% to 95%, especially if the installation is equipped with a battery that significantly increases self-consumption.

Each Energia project is subject to a personalized study in order to accurately estimate the savings that can be achieved based on your situation.

What assistance and regulatory framework should you be aware of?

Energia supports you every step of the way to ensure that your installation is eligible for subsidies and fully compliant with current regulations.

We take care of:
- The self-consumption bonus and the conditions for benefiting from it (power, surplus resale contract, administrative procedures).
- The reduced VAT rate of 5.5%, applicable under certain conditions for homes over 2 years old.
- Urban planning procedures, such as the preliminary declaration at the town hall or, more rarely, a specific permit depending on the type of roof.
- Electrical compliance and adherence to standards (Consuel, protections, sizing).
- The Enedis connection, as well as all the necessary procedures to activate your injection or purchase contract.

With Energia, everything is managed for you: you stay informed, but you don't have to deal with any complex procedures.

What happens if I have a problem with my installation?

We provide comprehensive after-sales service:
Hardware warranty (modules, inverters, batteries) and labor warranty in accordance with our contractual terms and conditions.
Rapid response in the event of malfunction (e.g., micro-inverter, damaged panel, battery).

We take care of maintenance, replacement, or repair procedures as necessary.

Do I have a choice in the equipment you install?

Yes. At Energia, we conduct a personalized study and tailor the equipment to your roof, your self-consumption needs, and your budget. You can request high-end options or a package optimized for your desired yield. We are not tied to any single brand and remain objective in our approach.

What warranty do you offer?

At Energia, we only install sustainable equipment backed by solid, recognized warranties.

Solar panels:
product and performancewarranties of up to 30 years, depending on the manufacturer.
Microinverters (e.g., Bourgeois Global): manufacturer'swarranty of up to 25 years.
Hybrid inverters (e.g., Solplanet): standard warranty of 10 years, extendable up to 20 years depending on the options offered.
Labor and installation: covered by our ten-year warranty and our professional liability insurance.

Upon commissioning, we will provide you with a complete file containing all warranties, certificates, and technical documents.

Do I need to plan for additional work (roofing, electrical) before installation?

In the vast majority of cases, you don't need to prepare anything yourself. During the technical visit, our teams simply check that the roof and electrical installation are compatible with your future solar system.

If minor adjustments are required (safety measures, electrical optimization, specific fastenings), Energia takes care of everything: we plan the necessary adaptations, provide a clear budget, and carry out the work without you having to lift a finger.

The aim is to provide you with a turnkey installation that is compliant and completely safe, without any complex procedures on your part.

In the event of resale or borrowing, what value does the installation add?

A solar installation generally increases the value of your property by reducing your energy costs and improving your energy performance rating, making the home more attractive to future buyers.
It also contributes to a more self-sufficient and better-rated home in terms of energy efficiency.

When you sell your home or apply for a bank loan, Energia provides you with all the necessary documents (certificates, performance data, estimated production) to clearly showcase the value of your installation.

Solar panels

How much can I really expect to save?

A properly sized photovoltaic system can reduce your electricity bill by 50 to 95%, depending on several key factors:
- Your consumption level and habits (hours of activity, energy-intensive appliances, presence of an electric vehicle, etc.)
- The orientation, slope, and sunlight exposure of your roof
- The installed power and quality of the panels (TOPCon, HJT, etc.)
- The inverter technology chosen (micro-inverters, hybrid)
- The presence of a physical or virtual storage system, which can significantly increase the rate of self-consumption
- The resale of surplus energy, which generates additional income

Thanks to a suitable and well-balanced installation, some households achieve near-total energy independence, particularly when they combine panels with batteries.

Our team systematically carries out a personalized study, based on your actual consumption and your home, in order to provide you with an accurate, transparent, and realistic estimate of the savings you can achieve.

What is the lifespan of solar panels?

The panels we install have a very long lifespan, with warranties of up to 30 years depending on the manufacturer.

These warranties cover:
- Product warranty (robustness and integrity of the panel),
- Performance warranty, ensuring 85% productivity after 30 years.
- The high-end technologies we use (TOPCon, HJT/heterojunction) enable stable production over time, low annual degradation, and optimal resistance to weather conditions (heat, UV, wind, humidity).

In practice, an installation can operate well beyond 30 years while maintaining excellent performance, securing your investment over the very long term.

In addition, Energia is certified by SOREN, the official body responsible for recycling photovoltaic panels in France.
This guarantees that your end-of-life panels will be collected and recycled in a compliant, transparent, and fully controlled process.

Which inverter technology should you choose?

The choice depends mainly on the configuration of your roof, whether or not there is shade, and the storage system you want.

Micro-inverters
Ideal when certain areas of the roof may be shaded or when the panels are spread over several sections.
Each panel operates independently, which optimizes production and allows panel-by-panel monitoring.

Hybrid or central inverter
Perfect when the roof is well exposed and unshaded.
This is a reliable, high-performance, and economical solution, particularly suited to homogeneous installations.
It also allows you to add a physical battery if you choose a hybrid model.

In all cases, our technicians will guide you towards the technology best suited to your configuration to ensure the best production.

How does the resale of surplus electricity work?

The electricity generated by your panels follows a very simple order of priority:
- Your home consumes the energy generated as a priority.
This allows you to directly reduce your bill.

- The surplus is then directed to your storage system,
whether physical (battery) or virtual (MyLight150 digital battery).

- Finally, the remaining electricity is fed into the grid.

This surplus is automatically purchased by an energy supplier—usually EDF Obligation d'Achat (EDF OA)—at a rate set by the government under a contract.

This mechanism allows you to maximize your self-consumption, benefit from optimized storage, and generate additional income by reselling the surplus.

Do the panels still produce energy in bad weather?

Yes. Photovoltaic panels continue to produce energy even in overcast conditions, low light, or less favorable weather conditions.

The latest technologies we install—TOPCon and Heterojunction—are specifically designed to deliver excellent performance in diffuse light conditions. They maintain stable production even in winter, early in the morning, or late in the day.

Storage solutions

What is the difference between a physical battery and a virtual battery?

Physical battery (local storage)
This is equipment installed directly in your home—for example, a Solplanet battery.
It stores the energy produced during the day so that you can reuse it in the evening or at night.
Capacity: generally 5 to 20 kWh depending on your needs.
Main advantage: immediate autonomy in the event of high consumption or a power cut (depending on the model).
Ideal for maximizing your self-consumption rate and further reducing your bill.

Virtual battery (digital storage)
This is a cloud storage solution, such as MyLight150 – MySmartBattery.
When your installation produces more than you consume, the surplus is fed into the grid and stored virtually.
Principle: 1 kWh fed in = 1 kWh that you can recover later, with no daily limit.
Main advantage: you get 100% of your surplus, even if you haven't invested in a physical battery.
The virtual battery acts as an energy account that can be used all year round.

In summary:
The physical battery gives you real autonomy and immediate use of your energy.
The virtual battery is an economical and flexible solution for storing your surplus without having to install any equipment.
The two solutions can even be complementary depending on your objectives.

What savings can I expect with a battery?

Adding a battery—whether physical or virtual—allows you to maximize the use of your own solar production and achieve a very high self-consumption rate, often between 75% and 95%, depending on your configuration.

In concrete terms:
- You consume your free energy, produced during the day, as a priority.
The battery stores the surplus for use in the evening, at night, or at times when the panels are producing less.
- You draw much less electricity from the grid, which significantly reduces your bill.

With a virtual battery, you also get 100% of your surplus, even if you don't have a battery physically installed in your home.

A well-designed installation, combining panels and a battery, can enable you to:
- achieve up to 95% energy independence,
- secure your costs in the face of rising electricity prices,
and optimize the return on investment of your solar installation.

During the personalized study, we calculate the actual gain precisely, based on your consumption, your production, and the recommended type of battery.

What physical battery capacity should you choose?

When it comes to physical batteries, their capacity must be adapted to your consumption habits and the power of your solar installation. Here are a few simple guidelines:

Standard home: a
battery between 5 and 10 kWh generally covers evening and nighttime needs.

High-consumption households (electric heating, heat pump, swimming pool, electric vehicle, energy-intensive equipment, etc.): a battery of 15 kWh or more may be necessary to optimize self-consumption.

Every situation is unique.

An Energia expert will carry out a personalized study to size your physical battery based on:
- your actual consumption,
- your usage time slots,
- the output of your panels,
- your autonomy goals.

This guarantees efficient storage and an investment that is perfectly suited to your needs.

How does the virtual battery work?

The MySmartBattery virtual battery requires the installation of a Coffret X and a MySmartBattery Starter Kit, which enable your installation to communicate with the MyLight150 cloud.

With a MySmartBattery subscription, your solar surplus is stored virtually without any limits: 1 kWh fed into the grid = 1 kWh recoverable later, at any time (evening, night, winter).

Energy is automatically managed by the MyLight150 ecosystem, without any physical batteries or maintenance.

To use MySmartBattery, you also need a MyLight150 electricity contract via Enedis, which is essential for virtual storage to function.

This system allows you to recover 100% of your surplus and optimize your self-consumption all year round.

Do the batteries work in the event of a power outage?

Physical battery: yes, if it is equipped with a backup system. This allows certain areas of the house to be powered in the event of a power outage. Without a backup, the battery does not operate in stand-alone mode.

Virtual battery: no, it cannot provide power in the event of an outage, as it is entirely dependent on the public grid.
