**2. The Results Characteristics of the "My Electricity" Program**

The My Electricity program was implemented in the years 2019–2020. The aim of the program was to increase the number of prosumers of PV micro-installations among households in Poland by over 200 thousand. The initial budget of the program was PLN 1 billion (Polish zlotys) at the end of 2020, and the budget was extended to approx. EUR 250 million (EUR 1 = PLN 4.5). According to the data as of 14 July 2021, the amount of funds spent was EUR 251 million; this value covers over 90% of the installations created under the program.

The main convenience for the beneficiaries was a non-returnable subsidy covering 50% of eligible costs up to a maximum of EUR 1111 per installation from the 2–10 kWp range. The eligible costs include the purchase of a new installation and its assembly. The installation is subject to control up to 3 years after the grant is awarded.

In the first round of the program, 28,457 installations were created (with a capacity of 158.4 MWp), i.e., approx. 15% of the total planned pool of installations for 2 years. The average power of the installation was 5.57 kWp, the median was 5.1 kWp, and the average subsidy amount was EUR 1102 (198 EUR/kWp). Detailed results by provinces are presented in Figure 3.

Most installations were built in the Silesian (4039), Masovian (3762), and Lesser Poland (3234) provinces with a total capacity of 61.4 MWp, the least in the Lubuskie (678), Warmian-Masurian (745), West Pomeranian (750) provinces, with a total capacity of 12.6 MWp. Less than 1000 installations were also built in the Podlaskie (781) and Opolskie (816) provinces. The average subsidy amount was PLN 4958 (EUR 890/kWp). The contrast in the number of installations is surprising—voivodeships with the highest number of installations are adjacent to the areas with the lowest number of installations.

As of 14 July 2021, 197.997 installations with a total capacity of 1137 MWp were built in the second round of the program [46]. This is about 8 times more installations than the first round. The average power of the installation is 5.73 kWp (+3% compared with round no. 1 [36]), and the median is 5.25 kWp. The average subsidy amount was EUR 1110 (193 EUR/kWp). Detailed results for individual voivodeships are presented in Figure 4.

Most installations were built in the Greater Poland Province (24,260) with a total capacity of 138.7 MWp. Similar values were achieved in the following voivodships: Silesian (23,121) Lesser Poland (21,747) and Masovian (21,482). The fewest installations were built in Podlaskie Province (4043), with a total capacity of 22.5 MWp.

In both rounds of the program, 226,454 installations with a total capacity of 1295 GWp were built. The average power of the installation is 5.72 kWp, and the median power is 5.22 kWp. The average grant amount is EUR 1109 (194 EUR/kWp). Detailed summary results for individual voivodships are presented in Figure 5.

**Figure 5.** Total results of the 1st and 2nd rounds of the "My Electricity" recruitment carried out in 2019 and 2020: power of installations (PI); number of installations (NI).

In total, in both rounds, most installations were built in the following provinces: Silesian (27,160), Greater Poland (26,657), Masovian (25,244), and Lesser Poland (24,981), with a total capacity of 596 MWp. In the years 2019–2020, the least interest in co-financing photovoltaic installations under the "My Electricity" program was in the Podlaskie Province (4824). The total installed capacity in micro-installations in Podlaskie Province was 26.7 MWp. The differences in power in individual provinces result, from population, urbanisation, insolation of regions [47,48].

It can also be observed that in each province the average installation capacity increased (Figure 6), despite the fact that the subsidy system is the most financially effective at installation capacity close to 2 kWp [48].

According to the weighted power of PV installations created under the "My Electricity" program, determined on the basis of the total power of the installations and geographical coordinates, the centre of Poland was determined to be in the Łódzkie Province—for the place of Łask near Łód ´z with coordinates 51.61◦ N and 19.18◦ E.
