Solar Panel Output Determines the energy a panel generates per day. Output = Panel Wattage × Sun Hours A 300W panel with 5 sun hours generates 1500 Wh.
Number of Panels Needed Calculates how many panels are required. Panels = Energy Need / Panel Output If energy need is 6000 Wh and each panel provides 1500 Wh, 4 panels are needed.
Battery Storage Capacity Determines battery size for storing solar energy. Battery = Energy Need / Voltage 6000 Wh at 12V requires a 500 Ah battery.
Charge Controller Sizing Ensures proper current flow to batteries. Controller Amps = Panel Watts / Voltage A 1000W system at 12V needs an 83A controller.
Inverter Sizing Determines the required inverter capacity. Inverter Power = Total Load Power For a 3000W load, a 3kW inverter is needed.
Payback Period Estimates how long to recover installation costs. Payback = Cost / Annual Savings A $6000 system saving $1000 per year has a 6-year payback.
Solar Panel Efficiency Measures how effectively a panel converts sunlight. Efficiency = (Power Output / Sun Energy) × 100% A 300W panel with 1000W/m² sun energy has 30% efficiency.
Roof Area Required Calculates how much space is needed. Area = (Panel Watts × Number of Panels) / Panel Efficiency 10 panels of 300W with 15% efficiency need 200m².
Environmental Impact Estimates CO₂ reduction from solar usage. CO₂ Saved = Energy Generated × Emission Factor A 5kW system saves around 3 tons of CO₂ per year.
