Sunshine in Le Havre

Le Havre is in climate zone H1 (North), with an annual irradiation of 1220 kWh/m²/year according to PVGIS data (European Commission, JRC). Façade maritime normande venteuse : les panneaux restent propres, l'ensoleillement estival compense les hivers couverts.

For a 3 kWp installation (6 to 8 panels), that means around 3,270 kWh of solar output per year, with a peak in June-July and a drop in December-January, typical of the zone.

Solar already installed in Le Havre

At the end of 2025, the national register of electricity generation installations listed 459 solar installations connected to the grid in Le Havre, with a total capacity of 13.6 MW. Of these, 447 are under 36 kW: they are mostly the roofs of private homes and small buildings.

The number of installations has been multiplied by 1.8 in five years: there were 249 at the end of 2020.

Over one year, these installations fed 14.6 GWh into the grid. This figure only counts the surplus that was sold: the electricity consumed on site by the households with panels is not included.

Price of a solar installation in Le Havre

The cost of a residential photovoltaic installation in Le Havre varies with the capacity, the type of roof and the installer. The prices below are indicative for the 2026 market, with 5.5% VAT subject to conditions (see below) or 20% if a condition is not met.

System size Gross price incl. VAT CRE bonus Net price Recommended profile
3 kWp · 6-8 panels 6,600 € Abolished 6,600 € Household of 2-3 people · ~3,500 kWh/year
6 kWp · 12-14 panels ~11,484 € −480 € ~11,004 € Household of 4-5 people · ~6,000 kWh/year
9 kWp · 18-20 panels ~16,236 € −720 € ~15,516 € Large household or EV · ~8,500 kWh/year
⚠5.5% VAT, 5 mandatory cumulative conditions: capacity ≤ 9 kWp · residential building (regardless of its age) · PPE2-V2 certification (carbon footprint below 530 kg CO2/kWp, which can be checked on certisolis.com) · compliant heavy metals content · active EMS/SGE mandatory since 1 January 2026 (an energy management system able to control the equipment). If even one condition is missing: 20% VAT on the whole installation. Batteries are always at 20% (legal exclusion). The CRE bonus is paid in a single payment by EDF OA (the feed-in tariff operator) when the Enedis (grid operator) connection is made, and your RGE-certified installer (French quality label) takes care of it.

Profitability in Le Havre: the full calculation

With 3,270 kWh/year produced and about 70% self-consumption (a household at home during the day or appliances scheduled for solar hours), here is how the savings break down for a household in Le Havre:

Self-consumption (~70%)
~458,0 €/year
2,289 kWh × 0,2001 €/kWh
Surplus fed into the grid (~30%)
~10,8 €/year
981 kWh × 0,011 €/kWh (surplus buy-back tariff, June 2026 ministerial order (arrêté))
~469 €
estimated annual savings
~14 years
payback period
ℹThese figures assume an average profile: a tariff of 0,2001 €/kWh (1 August 2026), an annual increase of 3% and about 70% self-consumption. Actual profitability varies greatly with the orientation (due south is optimal), the roof tilt, the presence of shading and how much you are at home during the day. A household that is away during the day can see its payback period lengthen by 2 to 4 years compared with the estimates above. These tariff-increase assumptions are reasonable but uncertain; if tariffs stagnate, the payback period lengthens.

Grants available in Le Havre (76)

In 2026, residents of Le Havre can benefit from several grants that can be combined:

  • CRE self-consumption bonus: abolished since 1 June 2026 for all new installations.
  • 5.5% reduced VAT: under 5 cumulative conditions: capacity ≤ 9 kWp, residential building (regardless of its age), PPE2-V2 certification (carbon footprint below 530 kg CO2/kWp), compliant heavy metals content, and active EMS/SGE mandatory since 1 January 2026. If a condition is missing: 20% VAT on the whole installation. Batteries are always at 20%. Check eligibility with your RGE installer.
  • MaPrimeRénov': does not cover photovoltaic panels that generate electricity. This scheme funds solar thermal (hot water), insulation, heat pumps and renewable heating, not PV.
  • Normandie regional grants: some regions and local authorities offer additional support. Ask your ADIL or the local Espace Info Énergie (energy advice centre).
  • Dedicated financing: ask your bank about financing offers dedicated to renewable energy.

Frequently asked questions: Le Havre

How much does a solar installation cost in Le Havre ?

In Le Havre, a 3 kWp installation comes to around 6,600 € including VAT (the self-consumption bonus has been abolished since June 2026, so the net cost is the gross cost). For 6 kWp, allow ~11,484 € gross. Prices vary with your roof and the installer: ask for at least 3 quotes from RGE installers.

What payback period can you expect in Le Havre ?

With 1220 kWh/m²/year of sunshine and savings of around 469 €/year on a 3 kWp installation, the payback period is estimated at ~14 years. This payback period depends on your self-consumption rate, the tariff of your electricity contract and the orientation of your roof. Our simulator calculates your exact payback period with the real PVGIS data for Le Havre.

What grants are available in Le Havre in 2026?

The main grants in Le Havre in 2026: VAT (the CRE self-consumption bonus has been abolished since 1 June 2026), 5.5% VAT under 5 mandatory cumulative conditions, including an active EMS/SGE since January 2026 (without an EMS: 20% VAT), and Normandie regional grants through the ADIL or the Espace Info Énergie. Note that MaPrimeRénov' does not fund photovoltaic panels, only solar thermal, insulation and heat pumps. Ask your bank about financing offers dedicated to renewable energy.

What capacity should you install in Le Havre ?

The usual rule is to aim for 1 kWp per 1,000 kWh of self-consumed annual consumption. In Le Havre (1220 kWh/m²/year), 3 kWp produces ~3,270 kWh/year, which suits a household of 2-3 people using ~3,500 kWh/year. For a household of 4-5 people (6,000 kWh/year), aim for 6 kWp. Our simulator optimises the capacity for your exact profile.
