The study has been done under real conditions in Hamedan a western province of Iran with harsh winters. Here, all the procedures of production from land preparation to harvest and finally the removal of residues were recorded. The fruit produced per square meter of covered area was 10.07 kg m^-2. Moreover, the parameters of energy consumption, energy output, net energy gain, specific energy, energy productivity, and energy use efficiency were 5.05 MJ, 18,560 MJ, -5.03 MJ, 217.60 MJ kg^-1, 0.0046 kg MJ^-1, and 0.0037, respectively. Water productivity was also 39.42 kg m^-3. The indicators obtained in this study showed the effect of surrounding environmental parameters on the performance in comparison with the literature. Additionally, it is estimated that to provide solar-based electricity for this greenhouse, roughly 110 square meters of solar panels are required. https://best.basu.ac.ir/article_6389_4eab60e55fe4c7dd567a0be28016bff3.pdf
