Wind-Diesel Systems

Making a hybrid power system work in the long run is not just about buying and installing the equipment. Like with any other technical system, there must be adequate documentation of the installation. Operators and maintenance personnel must have proper training. Funds must be allocated for maintenance and repair, e.g. to replace a worn-out battery bank or hire a specialist for troubleshooting.

Beginner's Guide To Solar And Wind Energy

The question is why are you interested in using solar or wind energy? Is it because you need some back-up electricity for when the utility grid is unavailable? Or is it because you want to spend less money per month on electricity?

Bringing Electricity To Bandundu Province - Zaire - KINGUNDA

As onlooking eyes filled with wonder watched, I assembled the three solar panels to the framework, it was time to hoist the finished array onto the roof. We were on the front side of the clinic and the ladder was not very good. We got the array to the top of the ladder but I could not get my helpers to go up on the roof.

Cost Effectiveness Of Photovoltaics - Solar Electric Power Panels

News articles indicate that photovoltaics are already cost effective in Hawaii and some parts of California. Photovoltaics are also cheaper than electric grid power if you wish to power a remote home that is more than 2 miles from the nearest power line.

EarthToys Introduction - Who Are We And What Are We Trying To Accomplish?

My view is that while we would all like to believe that the decision to use alternative energy sources by individuals will be justified economically ... or politically ... or culturally ... in fact the primary market growth for the products and services in this industry will be driven by responsible people who just want to feel good about the way they conserve or create energy.

Energy Conservation - Tips For Your Home

Solar electric systems have high up front costs. Before going solar electric, you should conserve as much energy as possible so that your solar system can be smaller. Here are some tips on conserving electrical energy.

Good Advice About Steam

Steam, as with other forms of alternate energy has it's realm. Where steam excels above the other common systems, is in an application that requires large quantities of controllable, useable heat.

Maximum Power Point Tracking

Maximum Power Point Tracking, frequently referred to as MPPT, is an electronic system that operates the Photovoltaic (PV) modules in a manner that allows the modules to produce all the power they are capable of.

PV Innovation - Here Comes The SolarQuilt

The design is simple yet truly effective in offering to the building owner an aesthetically pleasing, lightweight photovoltaic roofing system that rests on flat or low slope roofs, requires no roof penetrations, protects roofs from weather and UV radiation and produces cost effective solar electric energy.

Safer Lighting With Solar - Using The Sun For Emergency Preparedness

For emergencies there are all sorts of hand crank lights, solar flashlights, and low power LED flashlights. There's even a "shake-up" flashlight that uses a shaking motion of the hand to produce the needed power.

The New Energy Manifesto OR An Argument For The Steam Engine

Probably, the most practical machine ever devised for the purpose of energy conversion is the steam engine. That's right! The steam engine. Not only does it have multi-fuel capabilities, but it possesses the ability to convert resources in an unrefined state (potential energy) into useable work (kinetic energy).

Utilization of Forest Residue Project

Power Energy Fuels, Inc. (PEFI) has the opportunity to assist the US Forest Service in converting forest residual (wood waste) into a useful commercial product.

What Does Kyoto Mean To Me?

Embracing change is the answer! As a nation, we need to look at this as an opportunity rather than an obstacle. This attitude and approach will lower our cost of living while creating a new market opportunity for green technologies. This opportunity can lead us to new industries and new jobs carrying our economy forward into a future world where we have learned to optimize, to adapt and overcome.

Automated Window Shading

As compared with passive switchable glazing technologies such as photochromic or thermochromic -- which merely react to environmental conditions such as ultraviolet radiation or temperature -- SPD technology offers the user control over the amount of light transmission and much faster switching speeds.

Automating HVAC Registers

To make the motorized registers, I'm using standard units purchased at a local hardware superstore, and the small servo motors were purchased from a local hobby shop that deals in Remote Control cars, planes and boats. All that's needed is a simple circuit to control them.

SolarEdge Technologies - Solar Inverters, Power Optimizers and PV Monitoring

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
