The life cycle stages of photovoltaics involve (1) the production of raw materials; (2) their processing and purification; (3) the manufacture of solar cells, modules, and the balance of system (BOS) components; (4) the installation and operation of the systems; and (5) their decommissioning, disposal, or recycling (Fig. 1).
Assuming 12% conversion efficiency (standard conditions) and 1,700 kWh/m2 per year of available sun-light energy (the U.S. average is 1,800), Alsema calculated a payback of about 4 years for current multicrystalline-silicon PV systems.
Emissions are normalized for Southern European average insolation of 1,700 kWh/m 2 /year, performance ratio of 0.8, and lifetime of 30 year This chapter gives an overview of the life cycle environmental performance of photovoltaic (PV) technologies.
This chapter summarizes the results of PV life cycle analyses using as the main indicators energy payback times (EPBTs), greenhouse gas (GHG) emissions, and toxic emissions, based on actual data from the present-day commercial production of sc-Si, mc-Si, CdTe, and CIGS photovoltaic systems.
Throughout the work, we focus on the data obtained, which shows that the process of photovoltaic panel production itself is very energy-intensive, especially in the phase of photovoltaic cell production and solar glass production.
As solar panels have an expected life of at least 25 years, they will generate zero-carbon and zero-pollution electricity for decades after any carbon emitted during their production has been paid back.
The sun is the source of solar energy and delivers 1367 W/m 2 solar energy in the atmosphere. 3 The total global absorption of solar energy is nearly 1.8 × 10 11 MW, 4 …
