Photovoltaic solar panels in Le Locle

2 °C. These characteristics lead to high energy needs, with approximately 4007 Kj/year of heating degree days. Installing photovoltaic panels allows you to offset this significant consumption by producing renewable energy locally.

With an annual global irradiation of 1302 kWh/m²/year, the production potential remains significant despite the harsh mountain climate.

The best time to undertake this work is ideally during a planned roof renovation. By synchronizing the replacement of tiles with the installation of panels, you optimize labor costs and secure the tightness of your building before winter.

Since profitability depends mainly on the share of electricity consumed on-site, a well-thought-out system helps to stabilize your expenses against heating needs during the coldest months.

Anticipating the project allows for proper preparation of the application for the federal single remuneration from Pronovo, an essential support for reducing your initial investment.

The success of a solar installation relies on technical choices adapted to your roof. The yield depends on the inclination and orientation, with a local estimate of about 1146 kWh/kWc/year for a roof facing south with a slope of about 30°.

There are different types of materials : monocrystalline panels, widely used for their efficiency, and building-integrated solutions. The choice of range will depend on your objectives: maximizing self-consumption or selling the surplus to the grid.

Mounting systems must be robust to withstand the region's weather specifics. Inverters, responsible for converting direct current into alternating current, are also crucial and their choice influences the durability of the installation.

It is advisable to discuss with a professional installer the various available technologies to evaluate the relationship between investment and expected production.

Profitability depends mainly on the share of electricity consumed on-site; it is therefore wise to consider, according to your consumption profile, energy management or storage solutions to optimize every kilowatt-hour produced by your systems.

The building stock of Le Locle presents challenges due to its age and architecture. For buildings constructed before 1990, it is imperative to check for the potential presence of asbestos in roofing materials before any intervention.

Energy renovation works, such as thermal insulation of the roof, should ideally precede or accompany the installation of photovoltaic panels.

If your roof is not insulated according to current standards, a solar installation will not solve the structural heat losses, making bringing the envelope up to standard a priority.

Regarding networks, it must be ensured that the house's electrical panel supports the injection of solar power. Historic buildings sometimes impose constraints on the placement of sensors, requiring careful examination. Deducing investment costs to save energy is possible, but requires clear invoicing.

If you carry out maintenance work, a distribution by type is required according to a precise catalog to distinguish between improvement and simple maintenance.

Consult the municipal urban planning services to obtain documents regarding specific constraints on your building, in order to avoid any surprises when planning your solar installation.

In Le Locle, as in the entire canton of Neuchâtel, the procedure for installing solar panels is simplified. For so-called "sufficiently adapted" installations placed on a roof within the building zone, a simple notification procedure to the competent municipal authority is sufficient.

This process replaces the classic building permit, greatly facilitating the realization of your project. It is recommended to submit your complete file about twenty days before the scheduled start of the work.

This rule applies as long as the building is not located in a zone or object protected by cantonal law, which would require more specific authorizations.

As the local heritage is rich, the municipal urban planning service makes specific documents and procedures available. Before starting your procedures, contact these services to check the exact situation of your plot.

They will be able to guide you on any aesthetic or heritage constraints that could influence the choice of equipment, such as color or integration of the panels.

Transparency with local authorities from the design phase is the best way to validate your project without unnecessary delay, taking advantage of the simplified procedures for solar installations well-adapted to the existing building.

Investment in photovoltaics benefits from support mechanisms and advantageous tax measures at the cantonal and federal levels. The federal single remuneration (Pronovo) is the main aid for small solar installations. This subsidy significantly reduces your initial investment.

It is crucial to undertake the steps before the start of the work to guarantee your eligibility. Regarding taxation, investments aimed at saving energy are tax-deductible.

If these costs cannot be fully deducted in the billing year (year N) without generating a negative net income, they can be carried forward to the two following fiscal years (N+1 and N+2).

You have the choice, for each fiscal period and each building, between deducting actual costs and the flat-rate deduction. If you opt for the deduction of actual costs, be aware that a breakdown by nature is necessary if your work includes maintenance and improvement.

Note that if costs are carried forward, the flat-rate deduction will not be possible for the affected building during those years. The tax office determines the carry-forward costs officially. This rigorous management allows you to optimize your tax burden while financing your energy savings over the long term.

Ensure you keep all detailed invoices to justify your deductions to the cantonal tax authority.

The realization of a solar project in Le Locle must take into account seasonal constraints due to the altitude and 107 days of annual frost. It is preferable to plan the work outside of extreme cold, ideally between spring and early autumn, to ensure safe working conditions and optimal installation.

The typical process begins with a technical assessment followed by the application for the federal single remuneration. Once the aids are validated and quotes accepted, you notify the municipal authorities twenty days before the intervention.

Once the authorization or absence of opposition is confirmed, the site can begin. It generally includes the installation of load-bearing structures on the roof, mounting the photovoltaic panels, installing the inverter, and then connecting to the domestic electrical grid.

A testing phase is essential before the final commissioning to verify the good performance of the installation. Respecting the schedule is essential to avoid delays related to mountain weather, frequent at 921 meters altitude.

Consistent planning, starting several months in advance, allows for finalizing the installation in the best possible climatic conditions, thus guaranteeing the durability and efficiency of your solar equipment against the Neuchâtel climate.

To ensure the success of your project, avoid neglecting the structural condition of your roof before installing the panels. It is also a mistake not to anticipate the administrative steps for the Pronovo single remuneration before starting the work.

Do not settle for a single quote and always check if the company is specialized in local solar installations. Forgetting to contact the urban planning service beforehand is a classic mistake that can delay your project.

Checklist before requesting quotes : check if your roof is in good general condition, ensure you know the age of your electrical installations, examine your actual annual electricity consumption to correctly size the future installation, confirm the compatibility of your roof with municipal constraints, ask each installer for a clear simulation of the expected production, check the possibilities of tax deferral of costs, and ensure you understand how self-consumption works to make your investment profitable.

A sufficiently adapted roof installation is often subject to a simple notification, so check this possibility for your specific case.
