Building Electrification
When it comes to residential buildings, the electrical installations serve as the pivotal axis on which all of the other systems that are part of the electrical installation of each home, and which are later connected to it and other common systems such as, for example, elevators, will be based.
Lighting, air conditioning, and a broad array of household appliances are among the systems that will offer the home with a high degree of liveability and comfort when completed. As a result, buildings are divided into five categories based on the purpose they are intended to perform:
- Buildings that are designed to be used as residences.
- Buildings used for commercial or office purposes.
- Buildings that are open to the public.
- Buildings used for industrial purposes.
- Buildings designed for the concentration of industrial activities.
An electrical installation in a residential structure is comprised of the following components!
The following list includes the components of a building electrification installation:
- There’s a rush line.
- Box for general protection.
- Delivery Line.
- Counters are centralized.
- Referrals made on an individual basis
- Control panel as well as security.
The distribution network and connection line are the property of the electricity distribution business, although the installation itself, as seen from the general protection box, is the property of the customers. The most common calculations to be performed in electrical installation projects in a residential building, on the other hand, are those relating to the establishment of the following:
- Powers figures requested.
- Tension fall.
- Sections of conductors in various locations throughout the building.
Elevation levels or degrees of electrification for structures that are primarily intended for residential use!
The categorization of a residential building into levels or degrees of electrification is dependent on the amount of load or maximum simultaneous power that the system can sustain, as well as the amount of interior wiring that each residence possesses. There are four levels or degrees of electrification for these buildings, each with a maximum power capacity that is predicted for that level of electrification.
- A minimum of 3,000 watts is required.
- 5,000 watts for a medium requirement.
- A High Requirement of 8,000W.
- Unique to the project.
What factors go into determining the level of electrification?
This determination will be made in accordance with the purposes anticipated for the dwelling, as well as based on the preferences of the property’s owner, as well as other factors.
The minimal degree of electrification required for a residence whose future use is unknown and for which there is no owner since it is a construction site will, nevertheless, be determined by the surface area of the dwelling, as shown in the following table:
Electrification level | Area in m2 | Total maximum power demand |
Minimum | 80 | 3000W |
Medium | 150 | 5000W |
High | 200 | 8000W |
Special | Anyone | to project |
Rooftop Solar Panels for Home
A solar roof or a solar panel roof is generally used to refer to homes that have photovoltaic panels or solar tiles installed on their roofs in general. However, the first approach is more widely used than the second, despite the fact that both are valid and contribute to environmental sustainability.
The question then becomes, how much does it cost to install rooftop solar panels for home? Numerous factors influence the price, including the type of panel or tile used, the amount of energy consumed by the home, and the size of the installation. Regarding the type of solar panel, the most common are self-consumption and accumulation panels.
For example, in the first case, all of the energy produced is consumed in the house, with any excess energy being fed back into the system. The cost per installed kilowatt-hour is between 2,000 and 3,000 euros. However, if you choose self-consumption solar panels with accumulation, the cost might increase by up to 30 percent. In this situation, the extra energy is stored in a battery and used when the battery is charged again.
Cost of a Solar Roof Panel Installation!
The cost of a solar panel installation varies based on the size of the system and the level of competition in the market. An installation for a single-family home of between 2 and 7 kW in general ranges from 4,000 euros (VAT included) up to 9,000 euros (VAT included), although installations for neighborhood communities are typically more expensive depending on the availability of the roof cover. Depending on the structure, they can even reach up to 30,000 euros!
Installation
The installation of photovoltaic panels is possible in both multi-unit buildings and single-family residences. The most important requirements for its installation are that the roof is adequately oriented, has an appropriate slope, is accessible, and does not contain any external objects that cast shadows on the building.
There are many additional factors that must be considered in order for the solar system to work at its best. Aspects such as the quality of the structure and the manner in which it is installed are also critical for the proper performance and longevity of the plant, as well as the prevention of accidents caused by meteorological phenomena such as wind.
Amortization
When it comes to installing solar panels in a home, one of the most essential considerations is the length of time it will take for the investment to pay for itself. It is true that the initial outlay is significant, but the specialists begin to think about the long term once they have completed their analysis.
Amortization is dependent on savings and is often less than 10 years, even when grants are taken into consideration. As a result, this product should be considered a savings vehicle. In addition to amortization, a correct estimate would be to compare the investment to any other investment asset, such as a financial investment, in order to determine its value.
Any investment in photovoltaics, if done properly, can yield a long-term return of 10 percent or more each year over the long run. At this time, there is no risk-free financial investment product that will allow a tiny saver to get that kind of return on their money.But there’s more to it than that. With a well-built solar panel installation, you can save as much as 60% on your electricity bill.
The goal should be to consume 50% of the energy created on a yearly average basis, which would be a significant achievement. Therefore, the energy savings should account for between 40 and 60 percent of the client’s entire usage before the installation is completed.
