We usually measure or convert the watts into amps of solar panels to figure out how much current (amps) is being stored in the battery. Or we measure the amperage of the solar panel output to select the wire sizefrom solar panels to the charge controller. So if your goal is to figure out how many amps are. A 20W solar panel typically generates around 1.66 amps under ideal conditions, given that power (in watts) is calculated by multiplying voltage (in volts) by current (in amps). This calculation is based on a common nominal voltage of 12 volts (20W/12V = 1.66A). [pdf]

The is an 11 megawatt plant covered 150 acres (0.61 km ) and employs 52,000 PV panels. The panels are raised 2 meters off the ground thus allowing grazing to continue. The plant provides enough energy for 8,000 homes and saves an estimated 30,000 tonnes of per year. As of 2023, Portugal’s installed solar capacity exceeds 3 GW, with a target to reach 9 GW by 2030 as outlined in the country’s National Energy and Climate Plan (NECP). Solar energy accounts for 9% of Portugal’s electricity generation, with continuous growth expected in the coming years (source). [pdf]
