Contents Introduction Solar energy has experienced an impressive technological shift. While early solar technologies consisted of small-scale photovoltaic (PV) cells‚ recent technologies are represented by solar concentrated power (CSP) and also by large-scale PV systems that feed into electricity grids. The costs of solar energy technologies have dropped substantially over the last 30 years. The rapid expansion of the solar energy market can be attributed to a number of supportive

February 2014 (Intro) Solar Energy is an underrated renewable energy source. We should be looking to make advances to become more dependent on renewable energy sources such as solar energy. The more we rely on these new energy sources the more carbon dioxide‚ sulfur dioxide‚ and other greenhouse gases we could eliminate from the air which will help ensure a clean and safe environment for future generations. In addition‚ it could aid America to depend less on other countries for energy sources such as

INTRODUCTION When thinking of starting a contracting business for solar panels‚ many economic issues and concerns play a factor in the decision making process. Having a concern for the environment and knowing that solar panels have a cost saving for both households and business seems to be reason enough to start a business. However‚ before making such a financial investment you should first take a look solar panels in the economy in terms of (i) GDP growth rate‚ (ii) interest rates‚ (iii) level

A solar inverter‚ or PV inverter‚ converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequencyalternating current (AC) that can be fed into a commercial electrical grid or used by a local‚ off-grid electrical network. It is a critical component in a photovoltaic system‚ allowing the use of ordinary commercial appliances. Solar inverters have special functions adapted for use with photovoltaic arrays‚ including maximum power point tracking and anti-islanding protection

Advantages of and Problems with Solar Energy by Ethan Goffman I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that. – Thomas Alva Edison‚ 1931 The oil embargo of the 1970s prompted a national surge of interest in solar energy. A solar water heater was installed in the White House‚ and photovoltaic panels first came into play‚ notably in California. While previously solar power as a direct source of electricity

SOLAR POWER IN TODAYS WORLD JEROME T. GARDNER COLUMBIA SOUTHERN UNIVERSITY ABSTRACT Since first discovered in the 1860s‚ the concept of storing energy from the sun to use as a source of power has been studied and pursued by many programs. Either using solar collectors or photovoltaic cells‚ the methods of using solar power are becoming more efficient and cost-effective. Solar technology is currently being used by homes and businesses‚ but is still too expensive and risky for many residents. Researchers
