Solar dryers are well designed system to collect solar energy and utilize it for drying. Different types of solar collectors such as flat plate collector, concentrated collector and evacuated tube collectors can be used. Solar dryer are classified into direct, indirect and mixed-mode type depending on the design and construction. But the control of temperature for drying condition is still yet to be investigated.
How can agriculture be sustainable?
Proper management of energy is one of the main criteria for sustainable development in agriculture. Limited resources of fossil fuels and its negative impact on environment results in more focus on renewable energy. Renewable energy sources include energy from water, sun, wind, tidal, geothermal and biomass. Among these renewable energy sources, all are region based except sun and biomass. The total amount of energy received on the earth’s surface is just a fraction of total radiation of the sun. About 5,000 trillion kWh per year energy is incident over India’s land with an average value of 4-7 kWh per sq. m per day (https://mnre.gov.in/solar). The fraction of radiation includes visible light, infrared, ultraviolet and other traces of radiations. Both the electrical and thermal energy can achieve from solar energy through proper collectors.

Why is solar agriculture important?
For farmers with small tracts of land especially—like is commonly seen in France—solar agriculture provides a way to offset energy bills, reduce their use of fossil fuels, and breathe new life into existing operations.
How can agrivoltaics be used to grow crops?
So, Agrivoltaics could become the fast answer where large green houses with solar PV roofs power the growing process and if turned to hydroponics could be made vertical and capture more yield for longer growing seasons or year round growing seasons. The solar PV can be captured or used outright to drive the growing process and if automation is used also help in the harvesting of the crops from picking, to sorting, to packaging for cold storage before shipping to market. Drone and GPS technology has already changed the way farms are monitored and operated. A fully autonomous system using solar PV to charge battery powered implements with smart autonomous algorithms, like plow the old crop, till the soil, furrow and lay down the seeds and bubbler lines for irrigation without human labor. With the right equipment and solar power a “one man operation” could manage several thousand acres of crops every day.
