Small Scale Solar

Some of the Basics of Solar Electric Systems

Finding a way to decipher the different types of solar power systems in todays myriad of online articles can be daunting and confusing to say the least. Much of the public think that you have to have batteries in order to have solar power, this is untrue, as a matter of fact most residential solar systems being installed today are “grid tied” or “grid connected”, without batteries. No batteries required!

Photovoltaic systems can be configured in a variety of ways. This post describes the 7 main types of configurations and Check Out The Rest of “7 Main Types of Photovoltaic Systems” →

Home Energy Savings - 10 Tips To More Efficient Water Heating

Here are 10 great tips on how to make your water heating system(s) more efficient.
Part 5
Water Heating

Water heating is the third largest energy expense in your home. It typically accounts for about 18% of your utility bill. There are four ways to cut your water heating bills:  Use less hot water,  turn down the thermostat on your water heater,   insulate your water heater,  or buy a new, more efficient water heater.

A family of four, each showering for 5 minutes a day, uses 700 gallons of water a week; this is enough for a 3-year supply of drinking water for one person. You can cut that amount in half simply by Check Out The Rest of “Home Energy Savings – 10 Tips To More Efficient Water Heating” →

by Tina Casey

Working on a molecular level, scientists at the National Renewable Energy Laboratory and the University of Colorado are developing a crystalline “sandwich” that could increase the efficiency of solar cells by 35%. The process is delicate but if it can be commercialized, it would bring down the cost of solar energy and give a big boost to ambitious international solar projects like DESERTEC and the Sahara Solar Breeder.

US Navy Soars into $100M Solar Energy Future.

This is a good sign. We as a nation need more investment by the government and military into renewable energy sources. If solar arrays started showing up on all types of government buildings and military installations, I think that would without a doubt, increase consumer/investor confidence, which would in turn increase private investments into “utility grade” solar and other renewable sources. Why we have not set a Renewable Energy Standard in the US with Feed in Tariff Provisions is confusing to me and many other citizens. Maybe if this trend continues there may be hope yet !
