Solar PV investments in Bulgaria
Preferential conditions for stimulating photovoltaic development in Bulgaria include but not limited to special government guaranteed sell prices of power generating by PV (feed-in-tariff as minima) for 25 years as follows:

420 euro per MWh generated by PV up to 5 kW power.
386 euro per MWh generated by PV as high as 5 kW power.

Typical sun irradiation on Bulgarian territory varies from 1 300 up to 1 500 kWh/m² per year.

Spatially for solar parks, we are developed number of advanced solution to increase energy yield. E.g. - solar reflector system for conventional PV-array that doubling the energy yield of solar parks. This system allows to reduce significantly pay-back period of the solar park investment and to increase the internal rate of return.
Simple pay-back period of the PV investment in Bulgaria is 5-6 years.
Internal rate or return (IRR) is about 17%
The cost of PV solar power generated is about 0.1 Euro per kWh

Ecological advantages of building integreted PV-systems
Photovoltaic (PV) based electricity production is pollution-free at the local as well as the global level, it does not emit greenhouse gases, it does not dip into finite fossil fuel resources and it can be easily integrated into the urban environment, close to major consumption needs. However, prior to producing electricity, manufacturing and installing PV systems and later on dismantling and recycling them require spending a certain amount of energy, which must be “reimbursed” before PV can be considered as renewable and clean. The purpose of this report is to provide clear and well-documented answers to politicians, decision-makers and the general public about what PV can and cannot achieve in terms of renewable, clean energy production and environmental protection. The conclusion of this study is that, depending on the location, rooftop-mounted PV systems produce the amount of energy so as to recover their energy content from manufacturing and recycling in the range of 1.6 to 3.3 years and produce during their energy production period or service life between 17.9 and 8 times their initial energy content. Once they have reimbursed their initial energy input, rooftop-mounted PV systems can avoid, during their
lifetime, the emission of up to 40 tons of CO2 depending on their location and on the local electricity mix available.
Results for PV facades are logically slightly worse than for roof-top PV systems since they produce less energy for the same installed power. They produce the amount of energy to recover their energy content from manufacturing and recycling in the range of 2,7 to 4,7 years and produce during their service life between 10,1 and 5,4 times their initial energy content. Their contribution to CO2 emissions mitigation can be up to 23 tons of CO2 per kWp nstalled.
