>Electric cooking devices are challenging to operate on an off-grid solar PV system. For example, an electric oven requires between 1,000 and 5,000 watts of power, while electric stove burners have an average power consumption of 1,000 to 3,000 watts per burner. If you want to use an oven and one electric stove burner simultaneously, you need a solar array of at least 32 square meters in optimal weather conditions - just to cook. 1
You can overcome this problem by storing solar power in lead-acid or lithium-ion batteries. If these batteries are powerful enough, they can temporarily provide you with a higher power supply than your solar array can deliver. Batteries are also necessary if you want to cook after sunset or in bad weather, which is likely the case. Unfortunately, batteries account for 70-90% of the costs and the energy invested in a solar PV system. 2
