Net Billing

What is Net Billing and how does it work?

Net Billing is an innovative energy management system that allows self-producers to harness the power of Renewable Energy Sources (RES) to meet their energy needs and sell excess energy to the grid. With Net Billing, you not only reduce your energy costs, but also generate additional income, enhancing your energy autonomy.

How Does
Net Billing Work?

Energy production and consumption:

Η παραγόμενη ενέργεια από φωτοβολταϊκά συστήματα χρησιμοποιείται για την κάλυψη των άμεσων αναγκών του καταναλωτή.

Sale of surplus energy:

When production exceeds consumption, the excess energy is fed into the grid and compensated based on energy market prices.

Purchase of energy from the grid:

In cases of low production (e.g. night hours), the user can purchase energy from the grid, ensuring the uninterrupted operation of the system.

Συνδυασμός με σύστημα αποθήκευσης (μπαταρίες):

Net Billing can be enhanced by integrating energy storage systems (batteries), which provide even greater benefits:

Energy storage:

During peak production hours, excess energy is stored, rather than sold to the grid at a lower price.

Use of stored energy:

The stored energy is used in the afternoon or evening hours, when needs are increased or grid prices are higher.

Increased autonomy:

Dependence on the grid is reduced, while energy coverage is ensured during periods of high demand.

Advantages of Net Billing

01 Energy cost reduction:

Minimize your operating costs by consuming your own generated energy.

02 Additional income:

Selling excess energy to the grid offers you financial benefit.

03 Increased energy autonomy:

By using batteries, your autonomy increases, reducing dependence on external factors.

04 Protection against increases in energy prices:

You ensure the stability of your energy costs, even during times of energy crisis.

05 Environmental sustainability:

Actively contribute to reducing your carbon footprint by using clean and renewable energy sources.

Will you make money with Net Billing?

The short answer is: Yes, you can make money through Net Billing, but it depends on your consumption, the system’s output, and how you manage the energy produced. Let’s take a closer look:

How does the financial benefit work in Net Billing?

Energy consumption:

First you use the energy produced to meet your own needs.

This drastically reduces the costs you would pay to the grid.

Sale of surplus energy:

If your production exceeds consumption, the surplus energy is injected into the grid.

The grid pays you for this energy based on the wholesale market price (energy exchange prices).

Will you have immediate income?

Yes, if you have a surplus of energy:
If the photovoltaic system produces more energy than you consume, this surplus will be sold to the grid, creating additional income.

No, if your consumption is greater than production:
In this case, the energy you produce only reduces the cost you pay for consumption. There will be no surplus to sell.

How much money can you make?

Example 1:

You have a 10 kWp solar system that produces approximately 14,000 kWh per year.

You cover your energy needs and sell the surplus energy to the grid, generating additional income.

The result? Lower expenses – more money in your pocket.

Example 2:

With a larger solar system, you not only drastically reduce your electricity bill, but you also achieve a steady annual return from selling surplus energy.

Net Billing turns your electricity costs into an investment.

Advantages of selling energy with Net Billing

Additional income:

Excess energy is converted into money, further reducing the cost of your investment.

Reduction of the payback time:

The more energy you sell, the faster you will recoup your investment.

Environmental contribution:

Contribute to strengthening the grid with clean, renewable energy.

When is Net Billing most profitable?

High production – low consumption:

If you have more production than consumption (e.g., in a cottage used seasonally).

Efficient photovoltaic system:

The more efficient your system is, the greater the production and surplus.

Strategic use:

By combining Net Billing with a storage system (batteries), you can further reduce your dependence on the grid and increase your surplus for sale.
