Solar Panels

TIER1 solar panels are high-quality solar panels produced by companies with strong financial positions, established reputations and proven track records in solar panel manufacturing. These panels have high efficiency and are manufactured to strict quality standards. TIER1 solar panels are often chosen by consumers and businesses looking for reliable and sustainable energy solutions.

It is important to note that not all solar panel brands that call themselves TIER1 actually meet these quality standards. Therefore, when purchasing solar panels, it is always advisable to research the reputation and quality of the manufacturer and their products.

A string inverter and a microinverter are both types of inverters used in solar energy systems. The main difference between these two types of inverters lies in how they convert the direct current (DC) produced by the solar panels into alternating current (AC) suitable for use in households or on the power grid.

A string inverter is typically used in systems with multiple solar panels connected in series to form one long "string. The inverter converts the DC current of the entire string into AC current, making it suitable for household or grid use. String inverters are generally less expensive than microinverters and are often used in larger solar energy systems.

A microinverter is a smaller, individual inverter placed directly under each solar panel that converts the DC power from each panel into AC power. This allows each panel to operate independently of the others, maximizing system performance and minimizing the impact of shadow fall. Microinverters are generally more expensive than string inverters, but they can be more efficient and result in higher solar system yields.

Choosing a string inverter or microinverter depends on the specific needs and characteristics of the solar power system and your personal preferences and budget.

Yes, the installation of solar panels at private homes in Spain generally requires a permit. However, exact permitting requirements may vary depending on the region and municipality where the installation takes place.

In most cases, the installation of solar panels must be approved by municipal authorities and may also require permission from regional or national authorities. Depending on the size and power of the installation, there may also be technical requirements that must be met.

Yes, it is possible to obtain subsidies in Spain for the installation of solar panels in individuals. The Spanish government offers various subsidies and incentives to promote the production and use of renewable energy sources, including solar panels.

One of the most important grants is the "Program for the Promotion of Renewable Energy" (PROSOL) managed by the Spanish Institute for Energy Diversification and Saving (IDAE). This program provides financial assistance for the purchase and installation of solar panels and other forms of renewable energy sources for individuals and businesses.

Moreover, some regions and municipalities in Spain also offer their own subsidy schemes for the installation of solar panels and other forms of renewable energy. However, the terms and amounts of these grants may vary by region.

It is therefore advisable to contact the local authorities and energy companies to get more information about the subsidies available and the conditions for installing solar panels at private homes in Spain.

Yes, Eco Solar Technics will apply for the subsidies, with all obligatory formalities, for you in the case of a new installation.

An overview of the data Eco Solar Technics processes for you during the installation process:

Before installation begins:

1. Notification of works to the municipality
2. Application for any permits

After installation:

1. We inspect your installation
2. Report your installation to the grid operator. Your energy supplier will be notified of your installation within a period of approximately 8 weeks after the inspection. It will use this notice to personally invite you to discuss your feed-in tariff with you.
3. Apply for concessions:
   1. Europe
   2. Spain
   3. Communidad
   4. Municipality

To take control of this process, we require a signature of power of attorney at the start of your case.

A virtual battery in solar panels is a system used to store excess energy generated by solar panels for later use, without actually using physical batteries.

In this system, the excess energy produced by the solar panels is converted into electricity and fed back into the grid. The electricity delivered back this way is recorded and credited to the owner of the solar panels. Then, when there is a need for electricity, the owner can use this electricity from the grid, with the energy previously returned as a credit.

So in this way, the virtual battery functions as a kind of storage system, storing excess energy that can be used later. This system is especially useful for households that have solar panels but do not want to purchase or install physical batteries.

All Eco Solar Technics' on-grid installations are compatible with the virtual battery.

Ask our advisors for more info on virtual battery.

To clarify, we first make the distinction between the grid operator and energy supplier.

Grid operator: Provides infrastructure (cabling, meters)

Energy supplier: Supplies and charges for your electricity consumption

Procedure:

1. Once your solar installation has been installed and inspected, the grid operator (usually Iberdrola or Endesa) will be notified.
2. This in itself takes about 8 weeks to process your file.
3. Your system operator will notify your energy supplier.
4. Your energy supplier will invite you to discuss your "new tariff" with injection of energy into the grid.

In addition to the traditional injection of energy (with refund) into the grid, you can consider going with a virtual battery. This is a service offered by energy suppliers in the Spanish market.

Notice. The entire above procedure must be completed before you can switch energy suppliers.

There are several parties offering such a service. Ask our advisors for more info.
