Solar panels are on the rise! Producing your electricity or heating your home using solar energy, which is renewable and free, is attracting more and more households.
There are many good reasons for opting for a solar installation: energy savings, self-consumption, housing development, resale of electricity, and recycling. The juice box solar offers you a complete overview of the advantages of solar panels and reminds you of how they work. What are megawatts and gigawatts?
How does a solar panel work?
The principle of a solar panel is to exploit the energy emitted by the sun. But solar panels do not all have the same mission or operation. There are, in fact, two large families of solar installations. Understanding their mechanisms will allow you to become aware of their potential and better understand the related benefits.
The advantages of solar panels
Are you thinking about installing solar panels for your house? They offer a host of advantages, both ecologically and financially. The juiceboxsolar gives you the list.
Lower energy costs
Solar panels are an exciting investment to reduce your electricity or heating bill. Indeed, by producing and spending your solar energy, which is unrestricted, you save the purchase of it from your supplier. This is the principle of self-consumption, and you know what percentage of horses have solar power systems you can find out.
Please note: you cannot hope to use all the solar energy produced. Why? Because the peak of production occurs. When the sunshine is maximum, that is, in the middle of the day. At that time, electricity needs are often lower than in the morning or evening, periods when production is reduced.
Resale of excess electricity
The second criterion for the profitability of a solar panel is the case of a photovoltaic module. Indeed, the energy you do not consume is not lost: it is reinjected into the national grid.
Valuation of real estate
Another advantage of thermal and photovoltaic panels: they add value to your home. Note that a solar installation placed on a roof constitutes immovable property. Thus, it is impossible to recover a solar house’s panels when sold since they are an integral part of the building.
Local and renewable energy
Solar panels take advantage of solar energy directly from the sun. This is qualified as renewable energy because of the lifespan of our star, which is supposed to shine for another 5 billion years. On the scale of human time, solar energy is, in practice, considered inexhaustible.
How many solar panels do you need in your home?
As we know the benefits of solar panel, we should use them in our homes. Now the question is how many panels we need. It depends on different factors.
Energy Requirements
Your electricity needs are not necessarily equal to those of your neighbors, even if you have a similar dwelling and an equal roof area. These stem mainly from your consumption habits, the composition of your household, and the insulation of your home.
Immediate reflex to know its annual electricity consumption: refer to its electricity bill. The “consumption” part of your bill indicates the number of kilowatt hours (kWh) billed for a given period, i.e., the amount of electricity consumed in the house.
Have a self-sufficient home
This is your ideal, and that is understandable. You are probably wondering how many panels are needed to live in a fully autonomous or passive house. Better, with positive energy? The answer will depend on your energy needs and also your budget.
Indeed, succeeding in the ethical challenge of total autonomy means reviewing your consumption habits and planning colossal investments: storage equipment and larger installation to fully cover your needs even during the worst winter days.
And suppose the current performance of photovoltaic panels makes it possible to approach total energy autonomy. In that case, it is, however, not recommended to disconnect entirely from the electricity grid for simple reasons:
· If your energy needs exceed your instantaneous production, there will be no additional energy supply.
· Conversely, when your solar production exceeds your energy needs, you will not be able to sell your surplus
How many solar panels are for a house?
We found that the number of solar panels and profitability are directly linked. It is, therefore, impossible to ignore the factors that will have an impact on it:
· The power of your installation: victim of threshold effects, it governs your purchase price and the amount of your investment premium
· The sunshine and orientation conditions on which the production forecasts depend
· The usable area and its technical constraints
· Your energy needs and your choice of consumption (self-consumption or sale in full)
To be able to answer the question “how many solar panels are enough for my house?” it is necessary to find the best optimization without making mistakes in its calculations
Concluding Remarks,
That’s good. That’s why we invented a free simulator: juice box solar In just a few clicks. You identify the area available to you, the number of panels to be installed, the amount of your investment premium, and your profitability over 25 years. In addition to the results, you will get a complete study that will give you all the information you need to analyze and compare.
