Solar Energy Uses in Homes: Solar Guide

“When electromagnetic waves strike an object they can cause various effects, such as excitation of the molecules, excitation and ejection of electrons, and oscillation of charge carriers in the object. As the result, a portion of the radiated photons can convert to heat, electricity or chemical energy”

Solar Grid-Intertie Inverter

Solar Grid-Intertie Inverter

An inverter is basically an electronic device that takes a DC input voltage and converts it to an AC output voltage. My design takes a 12V DC input from my solar panels (two 50w panels in parallel) and converts it 120V AC at 60Hz which is the power that most home appliances use. A grid-intertie inverter connects up to and external AC power system and matches it’s internal AC sinewave to the external AC sinewave to allow the inverter to feed power into the external system.

Piezoelectric Energy Harvester - V20w

Converts normally wasted mechanical energy in the form of vibrations into usable electrical energy. It uses the piezoelectric effect to generate energy from Vibrations. Piezoelectric Energy Harvester – V20w Some sources are Machinery in Oil and Gas drilling to refining. Machines in Industry and Manufacturing. Wind, Tide, streams also can be harnesses with small fixtures, jigs or devices for vibration sensor arrays. Applications – Wireless Sensors and small instruments need a way to recharge their lithium cells or even supercaps. Using solar and vibration harvesting, enough power can be derived to power efficient electronics. Recharge small computers and tablets. From [Read More ....]

Supercap and White LED and Energy Harvesters

This is a educative and simple example to help learn about supercaps and white LED. It will also help you understand component behavior. If you are learning electronics, try this one out. The goldcap-Dynamo Lamp idea is a DIY Tutorial by Kainka on Electrical Energy Harvesting. What may be this EH Thing ? Energy harvesting (also known as power harvesting or energy scavenging) is the process by which energy is derived from external sources (e.g., solar power, thermal energy, wind energy, salinity gradients, and kinetic energy), captured, and stored for small, wireless autonomous devices, like those used in wearable electronics [Read More ....]

LED Lighting is gradually replacing CFL Lamps because they are more frugal in drawing energy and last many years. These have been around for some years and the technology is progressing. Now LEDs which show the illuminated objects in their true colors (like sunlight) are also coming. Due to the green initiatives of many countries, people have become aware and also implementing these solutions. These become a necessity when you start using Solar Panels for Home Power. The CFL lamps have reduced the use of the Filament Bulb due to lower power consumption. Now LED lamps may have to replace [Read More ....]
