The solar panels convert recovered renewable energy of sunlight into electricity through photovoltaic or thermal sensors. Thanks to the many advantages of this device, the majority of French people opt to install a solar panel on their homes, mainly with the entry into force of the RT2012 regulation. As a result, new constructions are subject to standards in terms of thermal consumption and energy saving.
Are you planning to install solar panels on a new house? Discover through this article all the information that can help you during your process.
Produce electricity using solar panels
Solar panels are made up of silicon cells that transform the energy from solar radiation into usable electricity. Electrons sense sunlight and carry current to where energy is needed by moving through the layers of the solar module to the inverter.
The resulting energy is used as needed, either to supply the home independently or in addition to the energy from the electrical network.
The 2012 thermal regulations (RT2012) require the installation of renewable energy for any new construction of a single-family house.
The 2012 thermal regulations (RT2012) require the installation of renewable energy for any new construction of a single-family house. Its purpose is to limit the primary energy consumption of new buildings to a maximum of 50 kWhEP / (m².year) on average. Installing solar panels on a new house is therefore in line with this regulation.
RT 2012 also aims to:
Optimizing industrial and technological development for all equipment and building sectors.
Improve the level of energy quality of the building regardless of the system used.
Ensure a technical and economic balance between the energies used for the production of domestic hot water and heating.
The Thermal Regulations 2012 presents some requirements that we present to you below.
The minimum energy efficiency requirement of the building:
The bioclimatic or “Bbiomax” requirement represents the minimum efficiency of the building. This indicator must be below a certain Bbio max level and it is measured according to several variables (location, use, altitude, etc.). The objective of this requirement is to limit energy consumption.
The energy consumption requirement:
The maximum conventional primary energy consumption requirement or Cepmax is an indicator for assessing energy consumption. It relates to the consumption of your heating, air conditioning, lighting, hot water production and pumps and fans. This requirement also requires the use of renewable energy systems in order to reduce greenhouse gas emissions. Of solar panels on a new home so you will fulfill this requirement and to efficiently produce electricity!
Summer comfort consists in keeping a pleasant temperature inside the habitat without resorting to an air conditioning system. This requirement uses the Tic indicator to calculate the temperature reached in a room during a period of 5 days during the summer season.
Why install solar panels on a new house?
The solar photovoltaic panels bring you countless benefits:
Electricity production that can cover a% of consumption: photovoltaic panels produce direct current which is transformed into alternating current via an inverter. Thus, thanks to this device, you self-consume your electricity and subsequently you reduce your bill by up to 50%.
Gain autonomy with batteries: batteries for photovoltaic solar panels make it possible to store electricity. It is possible to produce at a certain time of the day more electricity than you consume. So by selling this surplus you will make the installation price of the solar panel profitable.
Lower bills: installing solar panels on a new house is a solution to consuming electricity that you produce yourself. Therefore, it allows you to decrease your electrical expenses. Your energy consumption can therefore be reduced by up to 50%.
Valuation of real estate: renewable energy attracts many buyers today and investors in real estate. It’s a great way to increase the value of your property. This is called the green value of a house.
Greener house – reduced ecological footprint: based on renewable energy, solar panels are one of the best energy solutions with a carbon footprint. Installing these devices will allow you to reduce 86% of carbon emissions in a quarter of a century.
When should I install solar panels for the work?
Several places are possible to install solar panels on a new house: the roof, on the ground, on a pergola, on a carport, on the facade, etc.
In order to choose the type of installation that is suitable for your needs, it is necessary to study the project well and seek the advice of a professional. So, to optimize the performance of a solar panel, it is recommended to integrate them into the plans of your future home. Thus, the builders will take your requirements into consideration and they will choose the best orientation that goes with the chosen type of solar panel.
A new home with a roof well exposed to the sun
Unlike installing solar panels on an existing home which may not offer the best exposure (southeast, southwest) for collector sunlight , new homes are spared from this problem. During construction, the professional must choose the best orientation in order to reduce the energy needs. Indeed, the 2012 thermal regulations impose several rules such as the height of the construction, the length of the facade, the glazed or opaque surface must represent at least 1/6 of the total surface. Ideally, the house should have an orientation 50% south, 20% west, 20% east, and 10% north.
The aid available to amortize the investment:
Installing solar panels on a new house is considered a significant investment. Here are some available aids that will facilitate the purchase and profitability of your installation:
The photovoltaic self-consumption premium: the self-consumption premium is financial assistance that can be granted to individuals who install photovoltaic panels in their homes. To benefit from it, you must enter into the process of partial self-consumption with the sale of surplus electricity to a supplier, and choose an RGE-certified installer for the installation of your panels. The amount of the premium varies according to the power of the installation and is spread over the first 5 years of operation of the panels.
Aid from Anah: Anah (National Housing Agency) is an organization that offers financial aid for energy renovation such as the MaPrimeRénov device which is a bonus that merges the CITE (Tax Credit for the Transition Ecological) with another help from the Anah that is “Living Better Agility”. This bonus is intended for properties with modest incomes.
VAT at a reduced rate: this aid allows you to buy your equipment at a lower price. You benefit from a reduced VAT rate of up to 10% for photovoltaic installations.
Work to anticipate for greener consumption!
The cost of installing a solar panel on a new house may seem significant but it is a profitable investment given the countless advantages. With the RT2012 thermal regulation, you are forced to follow certain requirements for your new construction in order to limit energy needs.
To succeed in this installation in the best conditions, it is recommended to call on an RGE certified professional or to contact us for a free study request.
