Making Renewable Energy Easy

This site is all about Solar education. My goal is to help others take a complex subject and put it in a “It’s not rocket science” approach!
There are five principal renewable sources of energy: the sun, the wind, flowing water, biomass and heat from within the earth.
When it comes to Alternative Energy, it can be a little mind-boggling. There are lots of questions and too few answers.

Wind energy is a form of solar energy created by the uneven heating of the Earth’s surface by the sun. Most small wind turbines use a horizontal axis propeller, or rotor, to capture the kinetic energy of the wind and convert it into rotary motion to drive a generator, which usually is designed specifically for the wind turbine. The rotor consists of two or three blades, usually made from wood or fiberglass. (These materials give the turbine the needed strength and flexibility, and have the added advantage of not interfering with television signals.) The structural backbone of the wind turbine is called the mainframe, and it includes the “slip-rings” that connect the wind turbine - which rotates as it points itself into changing wind directions - and the fixed tower wiring. The tail aligns the rotor into the wind. WAIT! There is more to read… read on »

Today’s Inverters are designed in two different modes.
1. Modified Sine Wave
2. True Sine Wave. WAIT! There is more to read… read on »

A small charge controller usually contains a transistor that shunts the PV charging circuit, terminating the charge at a pre-set high voltage. Once a pre-set reconnect is reached, it opens the shunt, allowing charging to resume. WAIT! There is more to read… read on »

Solar PV Ground Mount:
The most common type of ground mount is constructed from steel supports with concrete footings. The rest of the mounting structure is built from aluminum or galvanized steel. Some Do-It-Yourselfers will even construct their mounting system from wood. WAIT! There is more to read… read on »

There are many types of solar panels out on the maket. Mainly you can break it down to Three different types. Monocrystalline, Polycrystalline, Amorphous
Monocrystalline Silicon Panels
Monocrystalline panels use crystalline silicon, a basic semiconductor material. The way to identify whether a panel is Mono or Poly is simple. A Mono panel has individual cells. A Poly type panel is solid with what looks like flakes of silicon pressed together. . Monocrystalline panels are typically 15-18% efficient, meaning that for every unit of solar energy that hits the cell, the panel can convert 15-18% of this energy into electricity. These panels are usually more expensive. WAIT! There is more to read… read on »

Solar energy basics consist of education, need, and planning. Educating yourself about the different types of systems can be a daunting task, with many products to choose from, yet not enough information to help you choose. Even if you decide to work with a solar professional, you might want to know if they are using the best solution for you, or if they are simply selling you the best solution for themselves. WAIT!
