Solar Power Adventures Some documentation on an photovoltaic, on-grid, tracker mounted solar power installation. This residential installation is the third on-grid photovoltaic system in Contra Costa County, California, U. S. A. and is the first in the county to use trackers.

Solar Promotion Association Full Cost Rates provide a full reimbursement of the money invested by a private or business in a grid-connected photovoltaic system. The utility buys the solar electricity fed into the public grid at a price that makes it possible for the owner to finance and maintain the photovoltaic system. The costs arising for the utility due to this payback rate are financed by a slight increase in electricity rates. The utility rate base is the sole source of funding. There is no need for subsidies from the state or taxpayer funding.

Solar Radiation Data A prototype of a common way to obtain raw data-in this case, solar radiation and climate summary data for selected locations across the US. This data is primarily intended for the siting, specification, and sizing of solar energy equipment.

Solar Thermal Electricity Production in Cloudy Areas In an attempt to demonstrate the practicality of solar electricity in the relatively cloudy Northeast US, the Pennsylvania Energy Office encouraged Thermacore Inc. of Lancaster, Pennsylvania to install a 5 kW dish Stirling engine system. The project is a joint venture between Cummins Power Generation Inc. (the manufacturer of the system), Sunpower Inc, several electric utilities, and a few universities and research laboratories.

Solar Thermal Systems Brief descriptions of various solar thermal systems (Solar Concentrators; Central Receiver Systems; Parabolic Dish Systems; Parabolic Trough Systems; and Solar Ponds).

Solar Thermal - What Is It? A fact sheet about solar thermal energy and its use in Hawaii.

solar tooling 2: Sun and Climate Modeling for Thermal Simulation A solar parametric model relevant at early design stages. The traditionally engineering-oriented approach to thermal building simulation tends to leave such analysis tools out of the reach of general design practioners, especially during early stages of building design when many of the most influential decisions regarding the thermal envelope are made. An alternative approach is proposed for making a situation-specific component of the overall thermal simulation model -- the ambient climate conditions -- accessible and informative at the level of schematic design considerations.

Solar Water Heating - Using the Sun to Heat Domestic Water Makes Sense in Almost Any Climate More than one million homeowners and 200,000 businesses across the United States have discovered that the sun can heat domestic water efficiently in almost any climate.

Solar Water Heating  This publication provides basic informa-tion on the components and types of solar water heaters currently available and the economic and environmental benefits of owning a system. Although the publica-tion does not provide information on building and installing your own system, it should help you discuss solar water heating systems intelligently with a solar equipment dealer.

Solar Water Heating Info Sheet Solar water heating involves the capture of the sun's energy to heat water. Useful heat in the range 20 oC to 100 oC is collected. This is commonly used for domestic hot water or for heating outdoor swimming pools. There are a number of different general designs and systems which can be used for solar water heating.

SOLASTAR  The most efficient solar water pump ever devised. SOLASTAR replaces traditional windmills and petrol/diesel pumps in most circumstances, and is therefore ideal for all-purpose economic water pumping installations where there is no viable electricity supply.

Space Heating with Active Solar Energy Systems  Solar space heating systems can be either active or passive. Passive systems use building components such as floors, walls, and sun spaces to collect and store heat. Often, small fans distribute heat, but mechanical equipment and the use of outside energy are kept to a minimum. In contrast to passive systems, active space heating systems rely on hardware such as rooftop collectors to collect and distribute heat. They use air or a liquid that is heated in the solar collectors and then transported by fans or pumps by a small amount of electricity. Solar heat is stored in water tanks or rock bins to provide heat during sunless periods.

Sun Angle This is the SunAngle calculator, which calculates the position of the sun and other terrestrial/solar angles based on your location and the time of day and year. This release is written in JavaScript, which allows the calculations to run on your local PC instead of on our internet server (this should speed things up a lot!).

SunsLab Concentrating Solar power technologies — parabolic troughs, power towers, and dish/engine systems — convert sunlight into electricity efficiently and with minimum effect on the environment. These technologies generate high temperatures by using mirrors to concentrate the sun’s energy up to 5000 times its normal intensity. This heat is then used to generate electricity for a variety of market applications, ranging from remote power needs as small as a few kilowatts up to grid-connected applications of 200 MW or more. CSP can begin providing energy, as well as economic and environmental security, for us today. In the long term, these technologies will compete broadly in U.S. and international markets for electric power production.

Sun Position This program calculates customized time series of various sun angles for specific locations that can be imported into spreadsheets and solar energy analytical software.

The North Carolina Solar Center Provides programs and resources which help people throughout North Carolina take advantage of solar energy. Services available to the public include a toll-free hotline, a referral network of professionals, technical and design assistance, free publications, curriculum materials for teachers, training sessions, tours of the demonstration Solar House, and a reference library.

Thermomax Manufacture Evacuated Heat Pipe Solar Collectors and Temperature Control and Monitoring devices in two state-of-the-art engineering and manufacturing facilities.

The Solar Century The Solar Century seeks to expand the use of solar power in order to fight global warming and promote sustainable development. We do this in two ways: by building a global solar consumer alliance of businesses, organisations, and individuals and by developing an investor's forum to promote investment in solar companies and projects. Income from both activities contributes to our Global Community Fund,dedicated to providing solar for those in need.

The UK SOLAR ENERGY Society The SOLAR ENERGY Society is a non-profit organisation. It is a forum for all those interested in the advancement of the utilization of the sun's energy. Members of the Society are drawn from industry, government, academic institutions, architectural and engineering practices, as well as the general public: academic qualifications are not a pre-requisite for membership.

Water Heating Calculator Water heating is a major energy consumer. Although the energy consumed daily is often less than for air conditioning or heating, it is required year round, making it a good application of solar energy. Use this spreadsheet to explore the energy usage of your water heater, and to estimate whether a solar water heater could save you money.
