“…For an insulated passive solar still, the minimum water depth is the optimum for distillate water productivity (Tiwari et al 2016). Tiwari and Sahota (2017) reviewed the effect of water depth in passive and active solar stills. In the present study, the productivity of the solar still at higher water depths can be increased by cooling the glass cover using a water jet (Tiwari and Sahota 2017).…”

In the present study, the productivity of the solar still at higher water depths can be increased by cooling the glass cover using a water jet (Tiwari and Sahota 2017). The daily productivity for square pyramid solar still using the automatic feed water system for the water depth 10 mm, 20 mm, and 30 mm is 2.8 L/m 2 , 2.56 L/m 2 , and 2.43 L/m 2 , respectively.…”

Herein, the water depth in a pyramidal solar still was kept constant using an automatic feedwater system through an auxiliary tank. Six water depths ranging from 5 to 50 mm were investigated. All variables were measured continuously but were logged automatically every hour. Increasing the water depth increased the water volume, thereby increasing the thermal capacity of the solar still. Therefore, increasing water depth increases the nocturnal yield but decreases the diurnal yield. Over the whole day, lower water depths resulted in higher accumulated yields. These accumulated yields increased by 37% by decreasing the water depth by 90% from 50 mm. The desalination system can work without human intervention, improving its sustainability. Moreover, the automatic feedwater system facilitates the end-user operation processes and succeeds in maintaining a constant optimal water depth in the solar still. KeywordsSolar still .

Intensitas radiasi matahari memberikan informasi besar energi yang ditransfer oleh matahari persatuan waktu. Informasi tersebut digunakan di banyak sektor untuk kebutuhan perancangan dan perakitan sistem dengan sumber energi matahari. Pengukuran intensitas radiasi matahari secara langsung memerlukan suatu peralatan dan prosedur yang komplek. Penelitian ini bertujuan untuk memberikan estimasi besar intensitas radiasi matahari sesaat dengan mengunakan metode konversi energi. Prinsip kerja dari metode yang digunakan adalah menangkap fluk energi radiasi matahari dengan sebuah luasan pelat tembaga hitam kemudian mengekstrak energi tersebut menjadi energi panas pada media fluida air melalui kontak langsung pelat tembaga-air. Besar perubahan temperatur pada fluida diukur sebagai fungsi dari lama waktu paparan radiasi. Nilai intensitas radiasi diperoleh dari penurunan nilai gradient kenaikan suhu yang dihasilkan. Hasil penelitian menunjukkan bahwa metode konversi energi memberikan nilai intensitas radiasi yang mendekati dengan nilai intensitas radiasi berdasarkan perhitungan formulasi astronomi. Di lokasi eksperimen, pada tengah hari, metode konversi energi memberikan hasil intensitas radiasi matahari sesaat sebesar 1149, 63 W/m 2 dengan selisih sebesar 0,59 % dari hasil perhitungan menggunakan formulasi astronomi.
