Solar Powered Heat Pump System - Research Paper Example Solar panels have been available for some time now. In 2006 B&Q, one of the largest DIY companies in the UK started marketing solar panels for around  £1,500 each. Microgeneration provides technology for ‘heat and/or electricity on a small-scale from a low carbon source’ (Roberts & Sims 2008, p. 363) and generated power should not exceed ‘50kW for electricity generation and 45KW thermal for heat production’ (Climate Change and Sustainable Energy Act, 2006 as cited in Roberts & Sims, 2008, p. 363).Scientists measure energy from the sun and translate it into ‘kilowatt hours per day per square meter’ (Caldwell 1994, p. 97). Sunlight that reaches the earth’s surface depends on latitude, the barriers like cloud or humidity. However, the sun’s energy is distributed in a uniform manner. For example, a rain forest in Washington is stricken by the sun’s energy, which is translated into 3kwh/d/m2, but southern Arizona and nearby are as receive 7kwh/d/m2. Full sunlight refers to a thousand for every square meter of global radiation. Companies that market photovoltaic forecast PV output with the use of computer models and simulation that include insolation data. In predicting an unknown area, they use the common rule of ‘plus or minus 10 percent on an annual average based only on latitude and closest weather data’ (Caldwell 1994, p. 98). There are factors that should be considered in determining costs of installations. Number one factor is the site and the weather. The photovoltaic output is sensitive to transients like clouds.
