What is Concentrating Solar Power?

Concentrating Solar Power’s (CSP) relatively low cost and ability to deliver power during periods of peak demand—when and where we need it—means it can be a major contributor to the nation’s future needs for distributed sources of energy. Large-scale concentrating solar power technologies include parabolic troughs and power towers.
There are more than 350 megawatts of [...]

A Solar Power Inverter: Its Purpose

by: Anna Williams
A solar power inverter forms an important part of any home solar energy system which supplies enough electricity to get you off the grid.
The inverter converts direct current, which is produced by a solar panel, into alternating current.
There is also a charge controller, which can use excess power to charge your system’s battery, [...]

Homemade Solar Panels – How to Build Your Own Solar Panels & Save 80% on Utility Bills!

Making your own solar power panels helps you save money on your utility bills by ensuring your alternative energy source is renewable and sustainable over the lifespan of the panels. In addition, you are protecting the environment as solar power does not emit harmful gases into the air in the process.
Contrary to general believe, assembling [...]

Homemade Solar Panels – The Pros and Cons of DIY Solar Power For Homes

Solar energy is a technology which has been around for more than 20 years, and has recently taken the lead as an alternative fuel source, thanks to the high and fluctuating oil prices. This is especially so in these times of global economic crisis with shrinking household budgets and escalating utility bills.

Sizing a Solar Water Heating System

Sizing your solar water heating system basically involves determining the total collector area and the storage volume you’ll need to meet 90%–100% of your household’s hot water needs during the summer. Solar system contractors use worksheets and computer programs to help determine system requirements and collector sizing.
Collector Area
Contractors usually follow a guideline of around 20 [...]

Diffuse and Direct Solar Radiation

As sunlight passes through the atmosphere, some of it is absorbed, scattered, and reflected by the following:
* Air molecules
* Water vapor
* Clouds
* Dust
* Pollutants
* Forest fires
* Volcanoes.
This [...]

Solar Radiation Basics

Solar radiation is a general term for the electromagnetic radiation emitted by the sun. We can capture and convert solar radiation into useful forms of energy, such as heat and electricity, using a variety of technologies. The technical feasibility and economical operation of these technologies at a specific location depends on the available solar radiation [...]

How to Evaluate Your Site’s Solar Resource for Solar Electricity

The solar resource across the U.S. is ample for solar electric systems—also known as photovoltaic (PV) systems—because they can use both direct and scattered sunlight. However, the amount of electricity generated at a particular site depends on how much of the sun’s energy reaches it. Thus, PV systems function most efficiently in the southwestern United [...]
