The technology also promotes sustainability by decreasing reliance on traditional energy sources and reducing overall world energy consumption. Properly sizing the system ensures cost-efficiency and optimal energy output. Solar panels also promote sustainability by reducing world energy consumption from non-renewable resources.
Environmental ImpactInvesting in solar panels contributes to sustainable development by reducing dependence on fossil fuels and cutting carbon footprint. Environmental Impact of Solar EnergySolar panels significantly reduce greenhouse gas emissions, supporting sustainable energy goals and mitigating climate change. Batteries store excess solar energy as direct current, which can later be converted to alternating current for nighttime or cloudy-day use. South-facing roofs in Ireland typically yield the highest electricity generation due to optimal solar radiation exposure.
Degradation The ability of solar modules to withstand damage by rain, hail, heavy snow load, and cycles of heat and cold varies by manufacturer, although most solar panels on the U.S. market are UL listed, meaning they have gone through testing to withstand hail.[41] Potential-induced degradation (also called PID) is a potential-induced performance degradation in crystalline photovoltaic modules, caused by so-called stray currents.[42] This effect may cause power loss of up to 30%.[43] The largest challenge for photovoltaic technology is the purchase price per watt of electricity produced. Advancements in photovoltaic technologies have brought about the process of "doping" the silicon substrate to lower the activation energy thereby making the panel more efficient in converting photons to retrievable electrons.[44] Chemicals such as boron (p-type) are applied into the semiconductor crystal in order to create donor and acceptor energy levels substantially closer to the valence and conductor bands.[45] In doing so, the addition of boron impurity allows the activation energy to decrease twenty-fold from 1.12 eV to 0.05 eV. Since the potential difference (EB) is so low, the boron is able to thermally ionize at room temperatures. This allows for free energy carriers in the conduction and valence bands thereby allowing greater conversion of photons to electrons.
