Frequently asked questions about selling excess solar energy

See more FAQs

What is solar energy?

Solar energy is a form of renewable energy that is obtained from the light and heat of the sun. Using panels, it is possible to convert sunlight directly into electricity. This technology takes advantage of the photovoltaic effect, where solar cells capture energy from the sun's rays and transform it into electric current, which can be used to power homes, businesses and even charge electric vehicles.

In addition, solar energy is considered clean and sustainable, as it does not generate polluting gas emissions during its generation process, helping to reduce the carbon footprint. Solar energy is increasingly popular because, as well as helping to preserve the environment, it allows users to reduce their electricity bills, especially when combined with storage systems that make it possible to use the energy generated during the day at night.

What are the advantages of being a solar energy producer?

If you're a solar energy producer, you're already contributing to a greener future. With MEO Energia, as well as generating clean energy through microgeneration, you can monetize your system by selling the energy you don't use. Our solution allows you to maximize the return on your solar panel investment and guarantee an extra income stream.

Mere Prior Communication/Operation Certificate: what do you need to know?

To ensure that your solar system is compliant, you need to make sure that your production unit is certified, either through the mere prior communication or an exploitation certificate, depending on your type of installation. This document certifies your ownership, so you can sell your surplus, which can increase your income and reduce costs in the long term.

Do I have to replace the energy meter to sell my surplus?

To sell the surplus solar energy produced at home, you need to replace your energy meter with a bidirectional (or smart) meter. The reason for this is that this type of meter is capable of measuring both the energy you consume from the electricity grid and the energy you return.

How does a solar panel work?

The sun shines on a panel that captures solar radiation. The converter then transforms it into electrical energy, which is injected through a normal socket to be consumed in your home. You can install the photovoltaic solar panel on the roof or elsewhere. Get to know MEO solar panels and find out how you can make your home more sustainable.

What is the aggregation business and who can join?

The aggregation business consists of selling surplus energy production (solar, wind, hydroelectric) to an electricity trader.
