In this article, a seven-level inverter powered by solar has been proposed to achieve a sinusoidal output voltage with high efficiency and enhanced power quality. This system consists of active inverter and flipped condenser clamping. It gives output voltage level of 2/3. By connecting the switched condenser branch in the front or back end series to the inverter output a seven-level output voltage wave shape can be obtained with ample non-work switching states to match the voltage of switching condensers. The consequence of the proposed method is validated using MATLAB SIMULINK for simulation. Comparing with conventional seven-level inverter topology, the proposed design used a minimal number of switches using a basic modulation process. The demand for electricity that is so high in India might be a key driver for the use of renewable power as an option for energy requirements. To satisfy this need, this article introduces a solar smart flower layout and then modeled using the resources provided in the solid function system. And use a set Photovoltaic panels harvest additional power mostly during 12 pm to 2:00 Pm in Nigeria which resulted in less renewable energy. Consequently, there is a need to increase the energy consumption of PV solar panel by developing a solar tracker cannot be overlooked. Photovoltaic cells must be aligned with the sun in order to just get optimum energy. The microcontroller is being used to power the motor dependent on information gathered from the LDRs. The findings of this research have clearly demonstrated that the monitoring solar panel generates more electricity compared to a conventional panel. The location of solar panel including voltage was going to monitor by using IoT. Light Dependent Resistors LDRs are being used to detect the strength of lighting and thus the PV solar panel is appropriately addressed to control maximum energy. The system uses motors to regulate the amount of the solar panel. The microcontroller is being used to power the motor centered on signals obtained from the LDRs. The outcome of this work has demonstrated clearly that the monitoring solar panel generates more power compared to a conventional panel. The location of solar panel and volts was going to monitor through using IoT.

a b s t r a c tPerformance of a doubly inclined solar still carrying pure water, salt water and seawater is explored experimentally and via mathematical models. Quantities of interest are the amount of water produced and temperature distribution within the solar still. The match between the model and experiments is qualitatively good, except that the model temperatures turn out to be higher, leading to an increase in the theoretical water production. The presence of solutes is seen to diminish water productivity, and the reduction in vapor pressure with solute concentration is the factor most responsible for this trend. The effect of cycle time and condensing film thickness on water production in context with the hydrophobic and hydrophilic glass surface has also been examined within the framework of the mathematical model. The extreme sensitivity of water production to water depth for small depths is explained in terms of the large latent heat of evaporation. Since lowering the water depth increases water production, this possibility of compensating for reduction in vapor pressure with salt concentration is explored. Large water production rate in a basic solar still is possible with a proper choice of operating parameters.
