The value of the investment in a 30kW grid-connected solar PV power plant depends on a number of factors. It depends on the type of equipment, the location of the property, as well as the type of structure on which the panels will be mounted. Equipment costs also often change depending on supply and demand at a given time. At the moment we offer design, delivery of the equipment, construction and commissioning of 30kWp at a value between 40,000 and 45,000 BGN incl. VAT.
The revenue from the investment depends mainly on the feed-in tartiff at which the respective Power Purchase Agreement has been signed. The tariff is determined with a decision of the EWRC every year on July 1. It is fixed for the term of the Purchase Agreement, but not longer than 31.12.2035. After this date, all solar PV plants start selling the produced electricity on the electricity market.
As of 1-07-2021, the tariff for feeding energy from a power plant with a capacity of 5 to 30 kilowatts is BGN 160,11 per MWh (excl. VAT). By law, EDCs are required to purchase the entire amount of energy produced by these power plants until reaching 1 380 hours of annual system operation time. A 30kW system in Bulgaria produces between 35 and 40MWh per year, which is within the allowable production for purchase at a feed-in tariff.
0.03 x 1 380 = 41.40 mWh
This production generates between BGN 6,000 and 6,500 per year for the investor. The revenue varies on a monthly basis, depending on the season and the intensity of sunshine in a given month.
The only costs are fees and taxes on these revenues. The system does not require any technical support. It needs regular cleaning of the solar panels to ensure maximum efficiency in their operation.
