Solar Power Technology

Power Analysts note that a third of the world's surface is covered by deserts with high levels of insolation and large, open spaces. If 4% of this surface were covered by solar photovoltaic systems the annual energy production would be equal to the world's energy consumption.

Principals of Solar Power Limited have worked on power generation and related industrial and economic development issues in desert areas of Oman, Yemen, Saudi Arabia, Jordan, Libya, Kyrgyzstan and Kazakhstan as well as in desert areas of the U.S., notably Nevada. In these areas, land is generally available for the installation of very large-scale solar electric power systems ("VLS_PV"), i.e. gigawatt-scale, in increments depending on local permitting and logistical requirements are met.

Solar Electric Power

Solar energy is the energy force that sustains life on the earth for all plants, animals, and people. The earth receives this radiant energy from the sun in the form of electromagnetic waves, which the sun continually emits into space

PV Terminology

(Solar Cell: The solar or "PV" cell is the component responsible for converting light to electricity. Some materials (e.g., silicon is the most common) produce a photovoltaic effect, whereby sunlight frees electrons striking the silicon material.

  • New PV modules generally retail for about $1 per peak watt, depending on quantities purchased. To estimate the total cost of a solar electric 'photovoltaic' power system, one generally doubles this cost to include the batteries, inverters, and other components, known as the "Balance of System" thus a budgeted cost for a PV system in the US would be about $3 per peak watt. A typical house with a 4KWp system would be budgeted at $24K while a 10MW utility-scale solar power system would be budgeted at$50--60M.

    The exact cost and installation time of a solar electric power system is typically determined by a 'Sizing Process' whereby one determines how much power is required for a specific application and when needed.
