A 2000-watt solar panel is rated to produce that much power under perfect lab conditions, called Standard Test Conditions (STC). This means strong sunlight (1000 watts per square meter), a cell temperature of 25°C (77°F), and a specific air mass.
A solar water pump sizing calculator is an online tool that estimates: Pump power (Watts) → how much energy your pump needs. Battery capacity (Amp-hours) → storage needed to keep water .
In Malawi, the average annual energy output for photovoltaic (PV) systems is approximately 1350 kWh/kWp to over 1700 kWh/kWp. 065USD per kWh for residential consumers and $0.
Today, the average residential solar panel is often rated 350–480 watts, with 400W becoming a common baseline. Higher-efficiency brands like SunPower and REC sell modules in the 430–480W range. Many reach these higher ratings through improved cell tech and half-cut designs.
