Understand how photovoltaic installations work with and without batteries

The first step in determining whether solar batteries are right for your installation is to understand how they work and their benefits. Traditional photovoltaic installations, without batteries, generate electricity using solar panels that convert sunlight into electric current. This electricity is then injected into the electricity grid under a purchase agreement with an energy supplier.

With solar batteries, you can store energy generated during the day when the solar panels are not producing enough, usually at night or during periods of low sunlight. Photovoltaic installations with batteries are usually used forSolar self-consumption

. This means that you directly use the electricity produced by your installation, which can further reduce your energy bills.

Criteria affecting the profitability of the installation

Several criteria should be considered to evaluate the profitability of a photovoltaic installation with or without solar batteries:

1. Your electricity usage profile: If your consumption is mainly daily, you will be able to use a large part of the electricity produced by your installation without the need for storage. In this case, a battery-less installation may be more cost-effective.
2. Electricity Rates: Savings from solar self-consumption depend on the cost of electricity in your area. If energy costs are high, the return on investment will be fast and the use of solar batteries can be interesting.
3. Average sunshine in your region: A favorable geographical location with plenty of sunlight is essential to ensure the profitability of your installation. Regions best suited for solar will be able to benefit from better efficiency and therefore better potential for profitability with batteries.
4. Cost of Solar Battery: It is important to compare the prices and quality of batteries available in the market. It is also important to consider their lifespan and storage capacity to assess their profitability.

Advantages of photovoltaic installation with solar batteries

Photovoltaic installations equipped with batteries have many advantages:

• Increase Self-Consumption: Using solar batteries allows you to use more of the energy produced by your installation, which directly lowers your electricity bill.
• Energy Independence: Having a reliable source of energy can make you less dependent on the electricity grid and protect you from price fluctuations or power outages.
• Respect the environment: Photovoltaic installations with batteries allow you to reduce your carbon footprint by using more renewable energy.

Disadvantages of photovoltaic installation with solar batteries

Despite these advantages, there are also disadvantages to equipping your photovoltaic installation with batteries:

• Additional cost: Adding solar batteries represents a significant investment, which can increase the total cost of your installation by 30% to 50%. However, the cost of batteries has come down due to technological advances and democratization of their use.
• Limited life: While solar panels have an average lifespan of 25 years, solar batteries typically have a shorter lifespan of between 10 and 15 years. So it will be necessary to plan to replace the battery at least once during the life of the installation.
• Complexity of installation: Add one solar kit Certain skills with batteries are required to ensure optimal performance. Specialists are better able to advise you on the options available and carry out installation in accordance with current standards.
