Photovoltaic solar panels in Morges: A complete guide for homeowners

The climatic context of Morges, with interesting global irradiation, makes solar energy particularly relevant for homeowners. The municipal Climate Plan sets ambitious goals to reach carbon neutrality by 2050, making every photovoltaic installation in the area an essential link in this strategy.

Undertaking work now not only contributes to these municipal goals but also protects against energy price fluctuations. The roof is an underutilized resource that, when equipped, turns a simple protective surface into a real clean power plant in the heart of the canton of Vaud.

The timing is also dictated by the current state of your property and the desire to improve its energy efficiency. If you are planning a comprehensive renovation or a change of heating system, integrating photovoltaics allows you to couple electricity production with the increased needs of a heat pump.

Taking advantage of a roof in good condition or a planned roof covering replacement is the ideal opportunity to limit labor costs and optimize the installation from the start.

The design of a photovoltaic solar installation in Morges relies on several crucial technical choices. The yield depends largely on the orientation and inclination of the panels, with an ideal inclination of around 30 degrees south often being sought.

The materials of the panels vary, ranging from monocrystalline cells, favored for their efficiency in small spaces, to building-integrated solutions (BIPV) that replace traditional roof tiles for a more discreet appearance, although often more expensive.

Each range offers different durability that must be compared according to your budget.

Beyond the panels, the inverter is the heart of your installation. It transforms direct current into usable alternating current. The choice of power for this device must be perfectly adjusted to the potential production of your panels to avoid energy losses.

Furthermore, battery storage systems are becoming an increasingly relevant option to increase self-consumption, especially when you use a heat pump or charge an electric vehicle. Intelligent flow management makes it possible to promote self-consumption, a key factor in the profitability of a domestic installation.

The housing stock in Morges is very diverse, ranging from historical buildings in the old town to recent constructions, with over 900 homes added between 2020 and 2022.

For houses built before 1990, it is imperative to be vigilant regarding the potential presence of asbestos in roofing or structural elements, which could complicate installation work.

Technical expertise is recommended to check the strength of the framework before installing any panels, as the additional weight, although moderate, requires a structure in good condition to guarantee the longevity of the installation.

In older buildings, thermal insulation is often the weak point. Before installing panels, it is wise to assess whether a roof renovation to improve insulation is not a priority, because installing solar on a poorly insulated roof amounts to producing energy that you will then lose through heat loss.

Finally, the internal electrical network must be checked to ensure it can support current injection and meet current safety standards. Bringing the electrical panel up to standard is frequently necessary during such an energy renovation.

In Morges, photovoltaic installations are generally subject to the simplified building permit procedure. However, the situation is more complex for protected buildings or those located in areas with high heritage value, such as in the old town.

It is strongly recommended to contact the Morges Building Police Office before making any commitment.

If your building is listed or located in a protected sector, the project may potentially have to be submitted to the Vaud State's Immeubles, Patrimoine et Logistique (SIPAL) service for approval regarding the aesthetic integration of the panels.

In some cases, a public or administrative inquiry may be required if the installation is deemed significant or if it changes the external appearance significantly. Never underestimate the constraints related to heritage, as compliance with local regulations avoids significant delays or even the refusal of your project.

Prior communication with the municipal authorities is the guarantee of a successful simplified procedure.

Consider this step not as an administrative constraint, but as a way to ensure that your solar installation integrates harmoniously into the Morges landscape, thus preserving the value of your property in the long term.

To reduce the cost of your photovoltaic project, it is imperative to follow a strict procedure: the application for aid must be submitted before the start of the work. The federal single remuneration, managed by Pronovo, forms the basis of financial aid, calculated according to the power of your installation in kWp.

It is also necessary to inquire with the canton of Vaud for possible additions, as aid may vary according to the regulations in force.

The profitability of your investment will depend primarily on the share of electricity you consume directly on site, which underlines the interest in coupling solar with energy management solutions.

Tax-wise, the canton of Vaud allows an advantageous tax deduction for investments intended to save energy. The deduction rate for these investments is 100%. If the costs exceed your net income for the year, you have the option of carrying over the balance to the next two tax periods.

You can choose between the deduction of effective costs or the flat-rate deduction for each building, but keep in mind that if you choose to carry over costs, you will not be able to claim the flat-rate deduction during that period.

This tax strategy can significantly improve the return on investment of your installation.

A photovoltaic project in Morges follows a logical sequence that begins with the planning and authorization phase. Once the authorizations have been obtained and the aid has been requested, the equipment can be ordered.

The actual duration of the work on the roof is generally fast, but it depends heavily on weather conditions. It is advisable to plan the work outside of periods of major frost, as Morges records an average of 43 frost days per year.

The safety of installers on a slippery roof is paramount, which is why companies often favor mild seasons.

The construction site includes the installation of the fixing structures, the installation of the photovoltaic modules, the wiring to the inverter, and the electrical commissioning. At each step, coordination with your electrician or installer is necessary to validate compliance with standards.

Finally, the connection to the grid requires the intervention of electricity distribution services to ensure safe and compliant injection. Anticipate these steps smoothly by planning a transition period where your installation will be tested before it is fully operational.

The key is good preparation in advance, which considerably reduces the presence time of technicians on your property.

The most common error is to neglect the structural condition of the roof before installation, which can lead to significant additional costs later on.

Never request quotes without having first checked the precise orientation of your roof, because a roof in constant shade from trees or other buildings will not be profitable. Make sure you have a clear vision of your annual electricity consumption, as this will determine the optimal size of your installation.

Do not neglect the administrative aspect by omitting to check heritage constraints, especially if you live in a protected sector.

Before soliciting companies, prepare your project by following this checklist: check the age and condition of your current roofing, measure the usable surface of your roof, identify potential shading throughout the day, obtain an estimate of your annual energy consumption, find out about the heritage specifics of your neighborhood, and prepare a list of questions about equipment warranty and after-sales service.

Require detailed quotes allowing you to compare technical services, the type of panels, the proposed inverter, and the installation service. A methodical and rigorous approach guarantees the success of your energy transition.
