The power of the solar panel that must be fully self-contained depends on the total energy consumption of the household or installation and the amount of sunlight available. Generally, to achieve energy autonomy, the solar panel system must generate enough energy to cover all energy needs, including peak usage.
This typically requires calculating the average daily consumption and then designing a solar panel array that can meet or exceed that demand throughout the year, taking into account variations in sunlight.
For a stand-alone home, the required solar panel power is calculated based on the energy needs of the home and the efficiency of the solar panels. This involves assessing the total energy consumption in kilowatt hours (KWh) and then sizing the solar panel system accordingly.
For a typical home, this can vary from 5 to 10 kW of installed solar panel capacity, depending on factors such as location, roof space and energy consumption patterns.
The maximum self-cohesion power is determined by the capacity of the solar panel system and the size of the battery storage. Self-awareness refers to the amount of electricity produced by solar panels used directly by the household or business rather than being fed into the grid.
To maximize self-cohesion, the solar panel system should be sized to match or slightly exceed consumption needs, and a suitable battery storage system should be in place to store excess energy for use when generating solar is weak.
Battery power for self-consumption must be sufficient to store excess energy generated by the solar panels for use during periods when solar production is low or absent. Battery capacity should align with the energy needs and energy patterns of the household or facility.
Typically, a battery storage combination with a capacity of 10 to 20 kWh can provide a significant amount of backup power, but the exact requirement will vary depending on the energy consumption and output of the storage system. solar panels.
To achieve electric autonomy, choosing the right battery involves considering factors such as capacity, efficiency, lifespan and compatibility with the solar panel system.
Popular battery types for solar systems include lithium-ion batteries, which offer high energy density and longer life, and lead-acid batteries, which are more affordable but have a longer lifespan. shorter. Battery selection should align with the overall energy strategy and the specific needs of the autonomous system.
