This study aims to design a Solar Home System with an Arduino-based Smart Switching system so that the use of electrical energy generated by solar panels can be adjusted without adding power from other electricity sources, such as PLN. Calculation of Leveled Cost of Energy (LCOE) is used as the basis for the switching process that will be carried out to regulate the use of household appliances that are routinely used, regulate electricity consumption automatically, minimize usage, and calculate the effectiveness of electric power usage. The way SHS works is to collect electrical energy from sunlight, then convert DC voltage to AC so that it can be used to run household electronic equipment. To accommodate the adequacy of electrical power, an automatic adjustment is made for household appliances that are routinely used, namely house lights, which includes setting the lights on and off and the number of lights that can be activated. The advantage of this research is that the SHS system is integrated with the automatic setting of the lights installed in the house so that the number of lights on will adjust the availability of electrical energy in the battery. In addition, with the LCOE method, the level of usage can be calculated so that users can save electricity. From the results of usage testing, it is found that the application of this switching technology provides benefits for users because it is no longer dependent on PLN supply. From an economic point of view, based on the calculation of Leveled Cost of Energy (LCOE), there is a kWh value savings of Rp. 77, - for each kWh price or about 4.53% compared to purchasing electricity with prepaid mode.

In the last years, an increasing number of countries has been affected by water shortage. Seawater desalination driven by solar energy, which is usually available in arid regions, might be a solution to satisfy the freshwater demand. In this study, the feasibility of a stand-alone multi-effect desalination (MED) plant driven by solar energy for an isolated community was studied. The system was made up of a solar field, a MED unit, and a thermal storage that mitigated solar energy fluctuations. Simulations with different top brine temperature and inclination and number of the solar panels were carried out in Matlab and Aspen Plus on an hourly basis by considering one typical meteorological year for ambient temperature and solar radiation. Two different sources of electrical energy were considered: A photovoltaic (PV) field and a diesel generator. The results were compared from an energetic and economic point of view, by considering the adoption of plastic as a material for MED heat exchangers. The maximum water production was obtained with December as the design month. Polytetrafluoroethylene heat exchangers allowed the cost of water to be reduced up to 9.5% compared to conventional exchangers. The lowest cost of water (7.09 $/m3) was obtained with September as the design month and a tilt angle of 45° with the PV field as the electrical power source.

The energy sector in Chile demands a significant increase in renewable energy sources in the near future, and concentrated solar power (CSP) technologies are becoming increasingly competitive as compared to natural gas plants. Motivated by this, this paper presents a comparison between solar technologies such as hybrid plants and natural gas-based thermal technologies, as both technologies share several characteristics that are comparable and beneficial for the power grid. This comparison is made from an economic point of view using the Levelized Cost of Energy (LCOE) metric and in terms of the systemic benefits related to flexibility, which is very much required due to the current decarbonization scenario of Chile’s energy matrix. The results show that the LCOE of the four hybrid plant models studied is lower than the LCOE of the gas plant. A solar hybrid plant configuration composed of a photovoltaic and solar tower plant (STP) with 13 h of storage and without generation restrictions has an LCOE 53 USD/MWh, while the natural gas technology evaluated with an 85% plant factor and a variable fuel cost of 2.0 USD/MMBtu has an LCOE of 86 USD/MWh. Thus, solar hybrid plants under a particular set of conditions are shown to be more cost-effective than their closest competitor for the Chilean grid while still providing significant dispatchability and flexibility.

The latest measure for the development of photovoltaics in Greece utilizes the net-metering scheme. Under this scheme the energy produced by a PV system may be either consumed by the local loads or be injected to the grid. The final cost reported in an electricity bill depends upon the energy produced by the PV system, the energy absorbed from the grid and the energy injected to the grid. Consequently, the actual electricity consumption profile is important to estimate the benefit from the use of this renewable energy source. The state latest statistics in Greece for households reveal that the typical electrical consumption is 3750 kWh while 10244 kWh are consumed in the form of thermal energy. We adopt in our calculations the above amount of electrical energy but assume four different scenarios. These different hourly profiles are examined to study the effects of synchronization upon the final cost of energy. The above scenarios are applied to areas in different climate zones in Greece (Heraklion, Athens and Thessaloniki) to examine the dependence of the hourly profiles and the solar potential upon the financial data with respect to internal rate of return, payback times, net present value and the levelized cost of energy. These parameters are affected by the initial system cost and the financial parameters.

Solar Electricity

Solar energy conversion is one of the most addressed topics in the field of renewable energy. Solar radiation is usually converted into two forms of energy: thermal and electrical energy. Solar electricity has applications in many systems such as rural electricity, water pumping, and satellite communications. A solar power system consists of solar panels, dc-dc converters, controller, and load. Charging a rechargeable battery requires a regulated dc voltage. However, the voltage supplied by a solar panel can vary significantly depending upon the day, time, weather condition, and irradiation from the sun. Since solar power is unregulated, it cannot be supplied to the load directly. Solar power is harvested and stored by charging rechargeable batteries. A dc-dc converter is connected between the solar panel and the battery to charge the battery with a regulated voltage. Therefore, solar power can be properly converted and controlled to provide required electrical power to the load, and excessive power can be sent back to the electrical grid.

The Difference

Solar panels (photovoltaics) function to absorb sunlight exposure to be converted into electrical energy. But if the heat received over the sun, it will reduce the electrical power of the solar panels. Therefore, a heat transfer device is required to maintain the temperature of the solar panels always in the optimal condition to work. The measurement results show that the average temperature out of the panel (T1) is greater than in the panel (T2), the upper temperature of the tank (T5) is greater than the bottom temperature of the tank (T6), and the average temperature value in the tank (T4) is between the upper temperature of the tank (T5) and the bottom temperature of the tank (T6) of any variation of the sender's media. Meanwhile, the difference between the entry temperature (T2) and the exit temperature (T1) in the study indicates how well the medium of the conducter absorbs excessive heat. Then it can be concluded that the medium of coolant is the best conducter media to absorb and conduct heat because it has a difference out panel (T1) and in panel (T2 amounted to 6.522 °c from Air Aki soft-0.0375 ° C, and water ordinary 1.069 °c. Panel surya (Photovoltaic) berfungsi menyerap paparan cahaya matahari untuk diubah menjadi energi listrik. Namun jika panas matahari yang diterima berlebih, akan mengurangi daya listrik hasil panel surya tersebut. Maka dari itu diperlukan sebuah alat pemindah panas yang mampu menjaga suhu panel surya selalu didalam keadaan optimal untuk bekerja. Hasil pengukuran menunjukkan bahwa rata-rata suhu out panel (T1) lebih besar daripada in panel (T2), suhu atas tangki (T5) lebih besar daripada suhu bawah tangki (T6), dan nilai rata-rata suhu in tangki (T4) berada diantara suhu atas tangki (T5) dan suhu bawah tangki (T6) dari setiap variasi media penghantar. Sementara selisih dari suhu masuk (T2) dan suhu keluar (T1) pada penelitian mengindikasikan seberapa bagus media penghantar dalam menyerap panas yang berlebih. Maka dapat disimpulkan media penghantar coolant adalah media penghantar yang paling baik dalam menyerap dan menghantarkan panas karna memiliki selisih out panel (T1) dan in panel (T2 sebesar 6,522 °C daripada Air Aki Lunak sebesar –0,0375 °C, dan Air biasa 1,069 °C.
