Our 4-step guide and free solar panel calculator are all you need to estimate how many solar panels you need at your location and what type of system is best to meet your goals: grid-tied, off-grid, or hybrid.
To calculate the number of solar panels your home needs, divide your home's annual energy usage, which is measured in kilowatt-hours (kWh), by your local production ratio.
On average, it takes around 2,857 panels, each rated at 350 watts, to achieve one megawatt of power. However, real-world factors such as space, orientation, and local regulations can influence the final number.
At a high level, solar panels are made up of solar cells, which absorb sunlight. They use this sunlight to create direct current (DC) electricity through a process called "the photovoltaic effect. ".
A PV array can be composed of as few as two PV panels to hundreds of PV panels. The number of PV panels connected in a PV array determines the amount of electricity the array can generate.
On average, homeowners can expect to pay approximately S$1,500 to S$2,000 per kWp for a residential rooftop solar system. Therefore, a 10 kWp system, suitable for many landed properties, may cost between S$15,000 and S$20,000.
