Everyone can be part of solar energy production
With Zerofy Shared Solar you can contribute to the growth of solar energy. Rent panels at our solar park, produce and sell your own green energy, and reduce CO2 emissions.
Help scale solar, without the friction3 simple steps to climate action.
Zerofy Shared Solar is the easiest way to support the growth of solar and get started with solar electricity production, even if you don’t have the ability to install your own panels. If you already have rooftop solar, it allows you to expand your portfolio. It’s solar, without the hassle.
-
Understand your needs
Start with renting a single panel, or as many as correspond to your household's annual electricity consumption. The minimum is 1 panel and the maximum is 25. Add more panels any time.

* How do we estimate earnings? The electricity earnings for this plant are based on Nordpool spot prices for Estonia. Electricity is sold to the grid at market rates, and the earnings minus a 20% commission are yours. The market price changes daily. We assume three scenarios for our calculations: 0.10 €/kWh, 0.15 €/kWh, 0.20 €/kWh and the numbers above are based on the middle scenario. The annual net profit down is the total profit over 25 years, annualized over that time period. You can check the current and historic Nordpool prices here. The current Estonian long-term fixed-rate retail prices between 0.18 and 0.26 EUR/kWh give an indication of market expectations for future prices and are higher than our scenarios above. The break-even price for the investment per panel is at 0.0711 EUR/kWh. (Historically, (pre-2021) prices sometimes have also been lower than 0.07 EUR/kWh.)
Benefits of Zerofy Shared Solar
Reduce
CO2 emissions
Deploying green energy is one of the most effective ways to reduce greenhouse gas emissions. Panels rented from our solar park generate additional green electricity that is fed into the grid. This replaces grid electricity from fossil fuels and thus reduces CO2 emissions.
No home installation
needed
Zerofy Shared Solar is ideal if you can't install solar at your home because you live in an apartment, rent, or have building code constraints. Even if you already have solar installed, you can generate additional electricity with Zerofy Shared Solar.
Protect against high electricity prices
If electricity prices increase, you will pay higher utility fees. But if you have rented panels in our solar parks, the proceeds from your panels also increase. This way you protect yourself against increasing energy prices, as the higher earnings offset some of your increased utility costs.
Earn money from green electricity
The electricity your panels produce is fed into the electricity grid and sold on the electricity market. The proceeds (minus a 20% operating commission) belong to you. This means by leasing our solar panels you save CO2 and earn money.
Contribute to energy independence
Building out renewable capacity helps increase energy independence for Europe as a whole, and the individual countries where our solar parks are located. Every single person who rents a panel with Shared Solar is making a direct contribution to this important effort, together.
Real-time CO2 savings and earnings in the app
Zerofy shared solar is deeply integrated with the Zerofy app. Avoided CO2 and earnings from electricity sales are shown right in the app and in real-time for all of your rented panels.
Current projects
Our current project is a pilot solar park consisting of 162 panels (67kW total). It is located in Kändliku, Estonia, and is expected to produce approximately 57MWh of electricity per year. The solar park is fully installed as of October 2022 and connected to the grid. Production of users’ panels will be visible in the Zerofy app from February 2023. This pilot project is meant to catalyze collective action for scaling renewable energy and we plan to expand to more countries once this first project is sold out.
The rent per panel for 25 years is 400 EUR.

Track CO2 savings with hourly granularity
As a world first, we calculate avoided carbon emissions at hourly granularity as opposed to yearly averages, as is common for green utility plans or offsetting products. This difference is crucial, as solar production is lower but also more valuable in winter. Takes into account real-time carbon intensity of grid electricity.
The impact
Zerofy Shared Solar differs from buying a green electricity plan or buying carbon offsets.
The impact is very direct, as the project is only built because you invest and rent the panels. This concept is known as additionality. Additionality means that a given project would not have happened anyway even without your investment. We also don't sell any carbon credits or certificates of origin for the solar plant. If we did, you couldn't claim the carbon reduction for yourself.
In contrast to green electricity plans, which calculate the electricity generated (and CO2 saved) on an annual basis, we calculate it on an hourly basis. (The key difference is that over one year, a plant may generate a surplus in summer, but a small amount in winter. This production pattern does not align with the actual consumption pattern, which is even over the year, or even higher in winter.) If you're based in Estonia or in Northern Europe, since the electricity from your panels is fed directly into your (Nordpool) grid, you can also consume it yourself.
Finally, to the best of our knowledge Zerofy Shared Solar is also the only carbon "offsetting" project that earns you money back.

The savings shown in the table above are an estimate. They are based on the difference of CO2 emissions of solar, and the grid's average emissions in the country the solar plant is located (Estonia in our pilot project). When the plant is operational, we will calculate the difference for every hour, taking into account the effective emissions of grid electricity for each hour.
Estonia presented a good first opportunity for a pilot plant because of
a) land availability
b) high emissions for average grid electricity (means high CO2 savings)
c) feed-in tariffs are based on market prices.
While Estonia is pretty far North and solar prodcution in the winter (Nov to Jan) is very low, in summer days are long and on an annual basis the total production is not very different from locations in central Europe, as can be seen on this map.
We don't. We only can present different future price scenarios. No one can predict the future. However, our current assumption is that electricity prices will generally rather increase than decrease over the next few years. And recent market developments have led to such extraordinarily high electricity prices, that payback can be very short.
Here are different scenarios for Zerofy’s Shared Solar pilot in Kändliku, Estonia. The table below shows CO2 savings achieved per panel, and income per panel for different future electricity price scenarios[1].
Yes! You will support transitioning a country with high emissions from grid electricity to lower emissions electricity. You will also help us build our pilot plant to prove the concept and later roll out the same kind of product in other countries. Please contact us with suggestions for other countries to launch.

As with any business, there are risks with solar leasing. One risk is that electricity prices are lower than expected and consequently your earnings are lower. The different scnearios presented on the website and looking at current and historic Nordpool spot prices, should allow you to get a picture of expected electricity prices.
Another risk is that Zerofy ceases to exist as a company. We do not see this as likely as we believe the need for a company like ours will only increase. However, in the unlikely event the company should go out of business, we would aim to refund the rental price of the panel prorated based on time elapsed.
