Typical Sizes and Power Output of Photovoltaic Cells

A successful sales professional spanning more than three decades of professional experience, Steve Verschoor is the co-founder of GTSP Global and oversees all sales and business operations of the company. Steve Verschoor has attended several solar power and photovoltaic conferences worldwide and has extensive knowledge of how various photovoltaics operate.

Solar photovoltaic cells convert solar energy (from sunlight) into electrical energy, which helps drive electrical current in circuits for various uses. On the quantum scale, solar energy comes from wavelike particles of radiant sunlight called photons. Depending on the wavelength of the light spectrum, each photon contains a specific amount of energy. The energy of the photons is absorbed by solar cells.

Solar cells vary in individual sizes, ranging from 1cm to 10cm across. At optimum capacity, cells of these sizes can produce 1 or 2 watts of electricity which is not enough to power most electronics. To increase power output to a sufficient level, multiple solar cells are connected to form an array of modules.
