“…c. Types of materials PV panels made by Different researches and developments are on-going on the manufacturing of solar cells to achieve better power output and efficiency of solar energy harnessing systems [83][84][85][86][87]. Mainly, the PV solar modules efficiency is decided by two factors: PV solar cell efficiency and total PV solar module efficiency.…”

PV solar energy is the upcoming king of the energy source in the world, which is the fastest growing, most available, sustainable, clean, and environmentally friendly renewable energy. The essential characteristic of PV solar energy is generating the maximum power at mid-day. At the same time, the energy demand is high during the daytime. Due to this, PV solar energy replaces the conventional energy demand at peak periods. The sun is the source of PV solar energy, and it changed into electricity directly by using solar cells, which are made from semiconductor materials called silicon. Therefore, PV solar energy plays a crucial role in providing usable energy, and as well as reducing carbon dioxide emissions. However, the solar energy generation systems not achieved the desired efficiency yet, because of many unsolved problems like weather conditions, losses, materials made by and so on. The aims of this paper is to review the current literature on the improvement of the PV solar energy generation system's overall performance. First, to figure out the existing challenges, like environmental factors and natural phenomena that affect the PV solar modules efficiency. Then it presents the techniques that are used to enhance the PV solar modules overall performance. Finally, to propose the best ways and techniques to improve the PV modules efficiency and suggest to further studies.

“…In 2018, Latvia had the third highest share of RES (40.3 %) in the energy con-sumption in the European Union (EU) after Sweden (54.6 %) and Finland (41.2 %), while the EU average indicator constituted 18.0 % [15]. In order to maintain its place, the Latvian operator directs all the energy produced by RES to its own consumption, and only surplus energy that is left at any given time can be allocated to hydrogen production.…”

“…Is it enough for a steady buffer level? The net electricity consumption in Latvia totalled 7 410 215 MWh in 2018, local generation covered 87.7 % of national consumption [15]. However, if we look at the volumes of electricity produced and consumed in Latvia in 2018 by month (Fig.…”

“…The reason is the spring floods and a high water level in the largest river of Latvia, the Daugava, on which three of Latvia's largest hydroelectric power plants are located. This amount of surplus electricity changes year by year, and an average value for last 5 years was 280 GWh//annually (2020 -45, 2019 -35, 2018 -5440, 2017 -817, 2016 -242) [15]. About 5090 tonnes of hydrogen can be produced from such amount of electricity (Table 1).…”

As EU is steadily moving in the direction of emission reduction, each country must develop plans to decarbonise the transport and energy sectors. In Latvia, transport sector is one of the biggest emission sources. The heating applications come next. Both require carbon containing fuels and a transfer to carbon neutral fuel is necessary; therefore, hydrogen may be the answer to achieve the overall EU targets. As Latvia has renewable energy sources, some production, storage and use of hydrogen are possible. Currently clear guidelines for Latvia have been investigated. The existing natural gas network may be used for two tasks: large-scale hydrogen transportation and decarbonisation of natural gas network. To open the natural gas networks for hydrogen, the first evaluations are made and a possible scenario for hydrogen implementation in network supplying consumers in the household sector is analysed to evaluate decarbonisation with an overarching goal of carbon neutrality.

Nowadays, any economic development is based on its sustainability. On the other hand, sustainability of the economy is no longer conceivable without efficient use of resources. Climate change and environmental degradation affects everybody and have no borders. It is essential, that all countries, regardless of their existing resources, are involved in environmental matters. The European Union (EU) has taken the initiative and has seen the possibility of transforming climate change into a guiding theme for sustainability and development in the economy. The EU has developed a green policy in order to transform all economic sectors into sustainable use of resources. EU is planning to achieve climate neutralisation in all sectors of the economy by year 2050. In order to achieve this objective, only the transformation of the industrial, transport and energy sectors will not be sufficient. The activity and willingness of each individual to achieve these objectives at their own household level will be crucial. It should change habits in all sectors important for households: food, transport, waste management and decreasing energy consumption in all mentioned sectors. Solar PV panels traditionally are used to reach zero balance, but taking in to account climatic conditions and seasonable solar irradiation activity, they can operate successfully during the summer and partly during the spring and autumn season. During the heating season, the efficiency of solar PV panel systems is very low. Use of innovative micro-cogeneration equipment producing both heat and electricity is more efficient during heating season in Latvia.In this paper case study of innovative biomass Stirling engine micro-cogeneration system integration with a solar PV panels in zero-energy family building will be present.
