    Why install solar panels?

  • Reduces energy costs
    You save on electricity, network charges and state taxes, and you can sell the rest of your electricity back to the network.
  • A smart investment
    An investment in panels is both stable and reliable, improves the energy class of the building and increases its market value.
  • The most environmentally friendly energy
    By generating electricity from the sun, you will reduce your carbon footprint, contribute to preserving the environment, and set an example for others.
  • Why Enefit?

  • Carefree and smooth process
    Our solar energy experts do their best to make everything go smoothly from idea to implementation. We think alongside you and create the best solutions, apply for the required permits and assist with the network contract. Moreover, we will buy back any excess electricity from electricity consumption.
  • Guaranteed quality
    Besides our valued expertise, we offer equipment from the leading producers of the world, and the installation will be handled by our experienced partners. Our equipment is covered by a 10-year warranty and our work by 2-year warranty.
  • We will always be there
    Since this is a long-term investment, we can guarantee that we will be there for you today and in the years to come.
  • Personal approach
    We find a solution that suits the possibilities and needs of each customer and helps lay the foundation for a more energy-efficient and environmentally friendly lifestyle. We also help finance the solution.
  • Completed works

    By today we have installed more than a 100 solar power plants across Estonia with a total capacity of over 7 MW. We install plants on both gable ​​and flat roofs as well as on the ground. Each solar power plant is a tailored solution and is designed according to the specifics of the building and the needs of the customer.

    Estonia Farm's solar power plant

    We installed a solar power plant with a capacity of 174 kW, consisting of 644 solar panels, on the roof of dairy farm Estonia in Järva county. It is a Solar Electricity Plus solution where the customer does not need to invest and the electricity produced can be cheaper for the customer than the electricity purchased from the network. Also, the price of solar energy is fixed for the entire contract period, so the more electricity price increases in the future, the greater the savings for the customer. The installed system covers about 15% of the customer's total annual electricity consumption, including more than a half of the company's daily consumption from April to August.

    Printing house Greif´s solar power plant

    Next to the production plant of Greif in Tartu, we built a solar power plant with a capacity of 216 kW, consisting of 800 solar panels. The installed system covers 20% of the total annual electricity consumption of the printing house and covers almost 3000 m2 of ground. It is also a Solar Electricity Plus solution.

    Solar power plant at the Tasku Centre

    We installed 560 solar panels on one of the largest shopping centres in Tartu, with a total power of 151 kW. The installed turnkey system covers 4% of the centre's annual electricity consumption. The project was complicated by a multi-level roof with several ventilation units. To ensure safety and bearing capacity, we made the required design calculations.

    BM Trade's solar power plant

    We built a 230 kW solar power plant on the property and rooftop of the eel trading company BM Trade in Viljandi, which allows the company to mitigate the risk of rising market prices of electricity because the favourable electricity price is fixed in the contract for 25 years. The plant, set up in Viiratsi, was designed with the energy needs of eel farming in mind, to cover all fish farming electricity needs and to sell the rest of the electricity to the network.

    Frequently Asked Questions

    A majority of solar power plants we see on the roofs and façades of buildings or on the ground need mains supply to function. Should the mains supply be cut, the production of solar energy also switches off. This means that, unless it is a hybrid battery solution, the solar plant will not work in case of a power failure.
    Generally, it would be good for a specialist to inspect the solar power system (visual inspection, circuit measurements, inverter software update, etc.) every two to three years. You don't need to worry too much about snow in winter either, as snow will not damage the panels and there is hardly sufficient sunlight in midwinter in any case. In autumn and spring when there is more light, the panel is capable of self-cleaning. That is, the panel will start generating electricity from the light glimmering through a thinner layer of snow, the panel will warm up slightly during operation, and this will help the layer of slow slide off or melt.
    Legal entities can apply for various public investment grants from Kredexilt, Prialt and the Environmental Investment Centre for the installation of a solar solution..
    Estonia is a suitable place for the production of solar electricity. In summer, the bright time of the day will start in Estonia earlier and end later than, for example, in Central Europe. Solar panels generate energy 12 months per year. The peak season for solar panels in Estonia is in April–May when the weather is cloudless and sufficiently cool. The panels produce energy even in cloudy weather and guarantee 10–20% of the yearly produced amount of electricity in autumn and winter.
    It would be good if the panels were facing south but this is not always possible. Contrary to popular belief, panels can be oriented to any cardinal direction, including north. However, you need to take into account there will be less productivity: At 35 degrees, east and west give 20% less output and north – 50%.

    Financial gain in 30 years

    The financial gain from installing solar panels consists of two parts:

  • Savings on electricity purchased from the grid – by consuming the electricity produced with solar panels, you save from electricity purchased from the grid, grid fees and taxes
  • Sales of electricity to the grid – the remaining electricity from your consumption can be sold back to the grid
  • In finding the financial gain, we have taken into account the average electricity prices and network charges for the year. We adjust the growth of electricity prices according to the long-term average inflation rate of 2%. The increase in network charges has not been included in the cost-benefit calculation. The financial gain is calculated for 30 years, which is also the period for which we give a performance guarantee for solar panels.

    Rate of return (IRR)

    The calculations are based on the following assumptions:

  • The lifespan of the project is 25 years
  • The positive effect of the investment results comes from:
    - the electricity not purchased from the network, and related network service fees, electricity excise tax and renewable energy fees.
    - the electricity sold to the network.
  • The base price of electricity is calculated as the weighted hourly average of the Nordpool Spot price in the year 2019 against the presumable hourly production of solar panels. The increase of the cost of electricity is assumed to be 2% per year.
  • The cost of the network service is calculated at EUR 24/MWh. It is assumed that the network service fee will not increase.
  • Calculations are with the current electricity excise rate of EUR 4.47/MWh and the current renewable energy fee, at the rate of EUR 11.30/MWh.
  • The return on investment does not include the one time fee for joining the network, which in the case of parks under 50 kW is usually up to EUR 1,000.
  • Support schemes

    It is possible to apply for governmental investment support to install a solar solution.

    More information can be found here.

  • Equipment and warranty

    We use the following devices from the world's leading major manufacturers to build solar solutions:

    PANELS: Recom. Both mono and polycrystalline panels are available.
    INVERTERS: Huawei

    Equipment lifetime and warranty period

    Solar panels have a life span of at least 25 years. Their capacity decreases by about 0.6% per year, and after 25 years the manufacturers guarantee a power output of about 85%. Only the inverter should be replaced about 15 years after installation.

    Appliances are subject to the following product guarantees - 15 years for panels and 5-10 years for inverter.

    We provide a 2-year warranty on the installation of the equipment.
