Solar installation with or without battery: at the car -he is upset

Solar installation with the battery is a promising solution for people and Breton companies anxious to reduce the electricity bill and their environmental impact. However, the question of autonomy often arises: Should we invest in batteries to keep solar energy and get rid of the electricity grid?

This article explores the advantages and disadvantages of the installations of the solar panel with and without batteries, taking into account the specifications of the Breton climate.

Advantages and disadvantages of a solar installation without sun battery

Advantages of a sunscreen without battery

1. Lower installation cost: the absence of batteries considerably reduces the initial investment cost.
2. Simplicity of installation and maintenance: a sunscreen without batteries is easier to install and maintain.
3. Immediate electricity production: all the energy produced by solar panels is consumed instantly, which optimizes the surrender.

Disadvantages

1. Dependence on the electrical network: without batteries, the excess of solar energy is injected by the network and not memorized. Therefore, the company or individual do not benefit from this production during periods of low sun or at night.
2. Electric invoices in winter: in winter, when sun production is lower, the company or individual will have to use the electrical network. This thus increases its invoice.
3. Lack of autonomy in case of current interruption: in the event of a current interruption, sunflower without batteries cannot provide electricity.

Advantages and disadvantages of a solar installation with solar batteries

Advantages of solar panels with battery

1. Increase in energy self -sufficiency: the batteries allow to preserve the solar energy produced during the day. So you can consume it at night, at night or in case of current interruption.
2. Significant reduction of electricity bills: the car -sunscreen of sun energy considerably reduces dependence on the electrical network, which reduces associated invoices.
3. Contribution to the energy transition: by memorizing solar energy, the company or the individual participates in the balance of the electrical network and the energy transition.

Disadvantages of batteries and solar panels

1. Higher installation cost: the addition of batteries significantly increases the initial investment cost.
2. Battery maintenance: batteries have a limited duration of about 10 years and require regular maintenance.
3. Energy loss due to storage: part of the sun energy is lost during the storage of the batteries.

Choose between a sunny installation with or without batteries in Brittany

The choice between a solar installation with or without batteries depends on several factors:

• Electricity needs: if the company or individual have significant electricity needs, especially in the evening or night, batteries can be an profitable investment.
• Budget: the initial investment cost must be taken into consideration, in particular if the budget is limited.
• Priority to self -sufficiency or savings: if the main objective is self -sufficiency energy, the batteries are essential. If the priority objective is to reduce electricity bills, an installation without batteries may be sufficient.
• Sunnyness: in Brittany, sun production is seasonal. If the company or individual want great autonomy in winter, batteries are recommended.

Alternatives to batteries

Other solutions can optimize solar self -consistency without batteries:

1. Auto -intelligent converse: the systems modify electricity consumption according to sun production. This limits the need for storage.
2. The sale of the surplus: selling the surplus of electricity to the network can be an interesting alternative. However, it depends on the attractive reimbursement prices.
3. Investments in high performance panels: the more efficient panels produce more electricity with less surface. This also reduces the need for storage.

Financial aid available in Brittany

Many financial aid are available in Brittany to encourage the installation of solar panels, with or without batteries. It is important to investigate the competent organizations to discover the aid to which companies and people are eligible. Know more

Conclusion

Solar installation with or without batteries offers advantages and disadvantages that it is important to analyze well according to your needs and budgets. In Brittany, the seasonal climate often encourages to opt for batteries for greater energy autonomy.
