Matrix solar air heaters – A review

Influence of Manually Adjustable Photovoltaic Array on the Performance of Water Pumping Systems

“…After estimating the optimal monthly slope, it is required to model the output of both the PV arrays and the water pump in order to determine how much water can be pumped each month. The same calculations can be made using a yearly Global Challenges 2019, 3,1900009 constant slope for comparative analysis. Figure 6a shows the IV-characteristics of a multicrystalline solar module, which has 60 cells connected in series and parallel combinations.…”

“…India gets 5000 TWh of solar insolation every year, with most regions receiving 4-7 kWh m −2 per day. [37] Delhi is one of the hottest regions in India, and receives an annual average of about 5.20 kWh m −2 per day energy from Global Challenges 2019, 3,1900009 the sun. [38] There is abundant use of groundwater for domestic and agricultural use in Delhi.…”

“…Out of the various renewable energy resources available, solar energy is the most promising as the sun gives out an enormous amount of heat and light. Many solar energy based applications are available commercially, such as solar cells, solar heaters, concentrators, distillers, etc . These devices have further been integrated with various appliances to achieve clean energy driven technology.…”

“…Many solar energy based applications are available commercially, such as solar cells, solar heaters, concentrators, distillers, etc. [1][2][3][4] These devices have further been integrated with various appliances to achieve clean energy driven technology. The photovoltaic powered water pump is one such application, which has received great attention in the past decades.…”

“…However, electricity and diesel based water pumps have several drawbacks. [8][9][10] In rural areas, where grid power is not accessible, or power cuts are regular, traditional electricity based Global Challenges 2019, 3,1900009 a water storage tank. Excess water can be stored for use at night or when the solar radiation is not sufficient to run the pump.…”
