“…The economics is very important to be considered for the drying system design. The payback period ( PP ) depends on the capital (or investment) cost ( CC ) and profit ( PR ) per the following equation (Fudholi et al, ):

italicPP = \frac{CC}{PR}

where the CC consists of the construction material cost and the construction labor cost, the PR is defined as the difference between total sales and expenses. The net present value ( NPV ) was also considered for the economic analysis as it is the difference between the value of cash inflow and the value of cash outflow during a certain period of time.…”

This research investigated the performance of a solar‐assisted heat pump dryer (SAHPD) with heat recovery to reduce the amount of thermal energy needed for drying chili peppers. The dryer selected for the experimental study consisted of a heat pump, a greenhouse cover and multi trays. It was found that the SAHPD with recovery gave better drying performance than a traditional dying method. The dryer system can offer drying time, drying efficiency, coefficient of performance and specific energy consumption of approximately 24 hr, 33.2%, 3.17, and 2.21 kWh/kg, respectively. Furthermore, the SAHPD with heat recovery provided a higher drying performance than without the heat recovery although the ambient condition changed. Base on the economic analysis, the payback period and net present value of the SAHPD with heat recovery were approximately 1.9 years and 915.60 USD. The SAHPD with two drying rooms also yielded better drying performance than the SAHPD with one room. Practical applications Drying is the process of moisture reduction to a safe limit of moisture content, which allows agriculture to extend the shelf life of the crops by restraining the growth of microorganism. In chili peppers drying process, a solar assisted heat pump drying as one of hybrid solar dryers is preferred because heat and mass transfer rate are rather high and it offers the ability to operate both daytime and nighttime. However, the exhausted air to the ambient still has considerable thermal energy. Thus, the heat recovery system has been employed to design and fabricate inside the dryer. Findings of this research contribute to the evaluation of heat recovery in a typical solar assisted heat pump dryer in terms of drying efficiency and economic feasibility in order to be a guideline for small and medium‐sized enterprises.

<span lang="EN-US">Growing concern with regard to energy sources and their usage has consequently increased significance of photovoltaic thermal (PV/T) collectors. A PV/T air collector is a system which has a conventional PV system combined with a thermal collector system. The system is able to produce electrical energy directly converted from sunlight by using photoelectric effect. Meanwhile, it also extracts heat from the PV and warms the fluid (air flow) inside the collector. In this review, solar PV system and solar thermal collectors are presented. In addition, studies conducted on solar PV/T air collectors are reviewed. The development of PV/T air collectors is a very promising area of research. PV/T air collectors using in solar drying and solar air heater.</span>

Solar energy is a clean energy, renewable, and available for the long term. The tool used to convert the energy generated from the intensity of sunlight into electricity is photovoltaic panels. However, due to the high cost and low efficiency, the use of the energy is still kind small compared to other types of energy sources. Thus, the need for an effective and flexible models, which resemble the characteristics of the actual photovoltaic (PV), so that we can perform simple manipulation of some data to figure out how to get the maximum performance possible. The characteristic of the solar panel output is specific and non-linear, it depend on the solar irradiation and the temperature of the solar panel. Because of it, it makes us difficult to get the Maximum Power Point (or abbreviated MPP) of the solar panels. Approach: Therefore, to solve these problems required the modeling of the solar panel for design and simulate the algorithms of Maximum Power Point Tracking (MPPT) to maintain the working point of solar panels fixed on the MPP. Overall, the designed system results carried are running well. The increase in the average value of the output voltage by 17%, from an average of 11.6 V before installation into 13.94 V after installation MPPT system. It also occurs in output power with an increase of 28%, from an average of 35.13 W before installing system MPPT into 48.9 W after installation MPPT system. The temperature effect on module voltage and output power before and after installation of the MPPT system that after the installation of the MPPT system, the voltage output of photovoltaic modules can be maintained around the desired maximum value that's equal to 12 V. But there was a drop in output power value compared to the prior installation MPPT system. This is caused by the output current value that cannot accommodate the value of the output voltage. So that the value of the output current is enough to produce the maximum output power is needed quantities corresponding load.
