When integrated with battery storage, solar also enables electrification and lighting in off-grid farms. The upfront capital cost of solar installations has been reducing significantly, and various incentive programs have enhanced the affordability for smallholder farmers.
On-farm Electrification A number of studies have demonstrated the effectiveness of small-scale solar PV installations for basic electricity needs of rural farms. Saxena and Kumar (2021) noted that even 1 kWp standalone PV systems enabled lighting, fan, phone charging in remote households.
Several studies have demonstrated the technical and economic feasibility of photovoltaic, solar thermal, and hybrid solar systems for various on-farm applications such as water pumping, crop drying, greenhouse heating. These systems provide clean energy for irrigation, milling, cooling, and mechanical operations to improve productivity.
This Guideline supports solar installations that are off-grid and include systems where all the energy is supplied from solar photovoltaic modules (or when a fuelled generator is used either as a back-up or daily).
