Your automated Guarantees of Origin
‍sales agent.

The Soldera Extra Income Calculator aims to provide an estimated overview of the potential additional income Soldera members may receive from the production and sale of Guarantees of Origin. The calculator is based on the following assumptions:
‍
• The user does not yet receive Guarantees of Origin, but is qualified to receive them. Thus, obtaining and selling Guarantees of Origin is a source of additional income.
• In Estonia, 1 kW of solar panels produces an average of about 1 MWh of electricity per year, but this can fluctuate from year to year.
• We have included in the calculator the estimated average annual price for Guarantees of Origin, but the actual price may fluctuate during the year. For more information, see the section “How much are Guarantees of Origin worth?”
• It is assumed that all electricity produced will be sold to the grid. If the point of production is connected, for example, to a private house, then the amount of Guarantees of Origin is affected by consumption.
• The sales revenue quoted in the calculator does not include VAT on the user's side and is before the deduction of fees.

In Europe, Guarantees of Origin' or 'GOs' are used to prove the origin of the electricity consumed. Many organizations want to use 100% renewable energy, but it is not possible to channel electrons from the producer to the consumer on the network. Therefore, a separate document is needed that grants confidence in the origin of electricity.

Renewable energy producers are entitled to receive Guarantees of Origin for each megawatt-hour (MWh) sold on the grid. After successful completion of the registration process, Guarantees of Origin will be credited to the manufacturer's account automatically every month. In Estonia, the official issuer of Guarantees of Origin is Elering AS.

In the event that the plant has received investment aid from the State after 15 June 2022 (and the beneficiary has not been determined by way of a reduced bid), an application must be submitted to offset the income from the Guarantees of Origin and the subsidies granted in order to participate in the market for Guarantees of Origin. Once the netting has taken place, the producer begins to receive Guarantees of Origin directly into their account.

Guarantees of Origin can be used to ensure the origin of electricity. Manufacturers have to find buyers for them themselves, because there is no public exchange for this.

Guarantees of Origin must be actively dealt with because they cannot be traded after 12 months and become invalid after 18 months.

There is no large public liquid market for Guarantees of Origin, and almost all transactions take place through private negotiations. It is therefore difficult to know exactly what value Guarantees of Origin could have at any given point in time. The opacity of the market means that often different people have very different perceptions of what Guarantees of Origin might be worth at the moment.

Historically, the highest selling prices have reached up to €8/MWh, but recently the price has been very volatile. We recently we wrote an article about how prices have moved in the international market for Guarantees of Origin on the example of French auctions.

No one can predict prices in advance, so it makes sense to sell as frequently as possible. This will help avoid a situation where Guarantees of Origin remain unsold and expire. We do everything we can to ensure a favorable price for our members.

No, these are different processes. Often, contracts for the sale of electricity do not contain conditions for Guarantees of Origin. Electricity and Guarantees of Origin produced by a production facility are usually traded separately because they are not directly related. The difference is due to the fact that it is not possible to target specific electrons for their intended purpose. Guarantees of Origin exist in parallel on the electricity market to ensure that renewable energy consumption does not exceed actual production.

Soldera does not buy or sell electricity, and our agreements do not place any restrictions on who buys and sells your electricity. We focus solely on Guarantees of Origin, providing you with a simple and automatic way to manage and sell them.

We turn Guarantees of Origin into a passive source of income. We help renewable energy producers of all sizes save their valuable time by automating registration, administration and sales. Once you join us everything works automatically and we try to mix our members as little as possible.

We take a commission based on the sales of your Guarantees of Origin. This helps align the interests of all parties to find the best price. The exact fee depends on the total capacity of the member's production facilities at all of their enterprises. The higher the capacity, the lower our fees. As an appendix note, the power is based on the power of the inverter.

* For small producers (< 75 kW), the default fee is 30% of the revenue from Guarantees of Origin sold. On special request, we offer the possibility of joining a fixed annual fee of 1 €/kW. This means that if you have a 15kW solar park, our fee is 15€ + KM per year. Any proceeds from the sale of Guarantees of Origin that exceed this amount will go to you. If this option is of interest, we recommend that you contact us. By default, the fee is approximately the same amount as €1/kW, but it guarantees income from Guarantees of Origin regardless of the market conditions of the year.

This should be compared to the time cost of selling and managing independently. Our members generally value their time highly and do not consider this risk to be significant.
