Energy Consumption Summary

Peak Power

  • ${} ${Math.round(item.power * item.workingTime)}Wh

Based on what appliances you would have in your solar system, we calculated out that you have the overall energy consumption of ${singleDayTotalCurrent}Wh/Day and peak power of ${peakPower}W in the solar system.

The calculation for Key Factors

According to your energy consumption and the region you lived in,the calculation shows a total off-grid peak power of ${peakPower}W,and a DC platform voltage of ${inverterVoltage}V.Based on these statistics,you need ${inverterVoltage}V ${Number.isInteger(batteryCurrent) ? batteryCurrent : batteryCurrent.toFixed(2)}Ah batteries and ${inverterVoltage}V ${inverterSpec ? inverterSpec : peakPower}W inverters to complete the solar system.

The Quantity of Solar Panels

You've select ${selectedPanel.spec.title}


Peak Power Pm(W): ${selectedPanel.spec.power}±3% W Open circuit voltage Voc (V): ${selectedPanel.spec.openCircuitVoltage}±3% V Short circuit current Isc (A): ${selectedPanel.spec.current}±3% A

Please make sure your installation area is big enough to ${selectedPanel.number} x ${selectedPanel.spec.power}W Solar Panels of ${selectedPanel.spec.size.width}*${selectedPanel.spec.size.height}mm.

According to the calculation above,you need ${selectedPanel.number} x ${selectedPanel.spec.power}W Solar Panels to fulfill your energy requirement.

Recommended Connection Type

Based on the information provided and the quantity of selected solar panels, we strongly recommend connecting them in the ${(connectMethod === 'tandem' || !connectMethod) ? 'series' : (connectMethod === 'parallel' ? 'parallel' : 'series and parallel')}.
