MPPT vs PWM Solar charger achievement - Part 1

MPPT vs PWM Solar charger performance / MPPT Operation / How does MPPT work / What is MPPT There is a follow-up to this video that covers some questions raised about the amps. MPPT vs PWM Solar Charger - Follow-up In this video I switch between an MPPT and PWM solar charger to show how much power (Watts) can be "lost". This is due to the voltage being pulled down to the battery voltage by the PWM charger. The MPPT controller uses / tracks the best voltage output the solar panel can provide to ensure maximum power output. In this case I have two 50 watt panels connected in parallel that can be switched between the MPPT and PWM charger. Together they are producing about 3 amps at 19.49 volts; about 58 watts (MPPT controller). When I switch to the PWM controller the voltage drops to the battery voltage being charged, 12.2 volts at 3.3 amps; about 40 watts. A loss of 18 Watts!! That means a 31% gain in power using an MPPT controller. The MPPT still provides the battery with about 12-14 volts required for charging but with more amps. The gains will not always be that big; as the battery charge voltage gets higher, the gains are less. The MPPT will continually track the optimum voltage; as light and temperature change at the solar panel, so will the Maximum Power Point. Here is an excellent link to a DIY project and further MPPT explanation: www.timnolan.com

Solar Panel Charging Lawnmower Battery

www.elperfecto.com ... Charging a Cub Cadet lawnmower 12V battery with a solar panel and Sunsei charge controller. The lawnmower battery will die during the winter months and will not start the mower in the spring unless it is charged. Charging the battery on a beautiful winter day helps ensure the mower will start up this spring.

Employment And Business Opportunities With Solar Panels

!±8± Employment And Business Opportunities With Solar Panels

As the cost of electricity continues to rise, more homeowners are starting to buy solar panels and install them as a means of lowering their utility bills. Temperature comfort has been a way of life for too long, and most individuals are only willing to be just so hot or cold. There has to be a more affordable means of enjoying the 'creature' comforts in life, and solar power is the next business to provide what the people want.

New technology continues to improve the possibilities of solar power. In its beginning, the efficiency ratings of the panels were not really all that good. But, new techniques and materials are starting to overcome the output wattage inadequacies, while continuing to offer up to 25 year manufacturers warranties. These panels offer hope of lasting much longer than it will take to pay for the units and installation.

Across the globe there are several countries currently involved in funding additional research into improved means of the photovoltaic process, and the resulting materials are proving to be even more durable. There are also materials being used that allow the new panels to actually be manufactured on a film and then rolled up for transport to the installation site.

Nanotechnology happened to stumble across a development in researching the reflection of light rays. When the discovery was realized it suddenly became a project to apply the same principles to solar cells, and the result was a solar panel with a 97% efficiency rating. This is something that was previously unheard of in hopes of solar applications. Now, there is the possibility that these panels could be used to cover outdoor walls and pick up sunlight from any direction.

Some of the applications for solar devices that are already in use are the lighted walkway fixtures which come on at dusk. Other outdoor lighting has included motion detectors to allow a panel smaller than one square foot to power flood lights. Dashboard panels which allow laptop users to recharge their machines, while using wireless to communicate via the Internet. Car and RV battery chargers which both charge and maintain standard automotive batteries. And, rural areas where conventional electric power is unavailable, now has solar power to operate well pumps providing water to remote livestock.

Several well known publications report that there is a new category of employees who are starting to replace blue-collar workers. These "green-collar workers" are being hired to fill jobs in the solar power industry, where these panels are currently being made. If the solar panels industry provides employment and business opportunities in every country, there will be many new jobs available and unemployment rates will go down.

Solar Powered Battery Chargers - Free Power From Heaven

!±8± Solar Powered Battery Chargers - Free Power From Heaven

With the rising price of fuel costs, the solar panel charger, and other solar power accessories, such as lights, batteries etc. have become increasingly popular. Basically Solar panel chargers work on the principle of collecting readily available sunlight and converting it into electricity. Solar power is a versatile source of renewable energy and it can be used in a varied number of applications, such as providing power for anything from cars and boats to homes and caravans.

The Solar power charge is collected uses photovoltaic solar panels. A solar panel charger is made up of panels each consisting of solar modules. These in themselves contain solar collector cells.

The Solar battery chargers are commonly used for outdoor lighting; they can provide all the luxuries of home while traveling; they will take a lot of the hardships out of your camping and hiking, and can provide much needed assistance during an emergency. They can also be used to supply the power for larger items such as small cars and handicap scooters etc.

Solar power can be used in a number of different situations such as in street lighting, keeping your business sign flashing, or small night lights to show the way in the home and garden. As well as the common necessities, the power generated by these solar panel chargers can be used for other resources, for instance, to supply the power needed for lighting and heat in homes, business, factories and schools.

A solar panel charger is extra convenient because all you need to run it is a period of direct sunlight on the panels. This makes a solar panel charger a must have portable source of electrical power. Solar chargers are indispensable in areas and situations where there is limited, or, even worse, no access to mains electricity; situations such as being out in the bush, working on a farm or ranch or even taking time off and relaxing on the beach.

Solar Power is more suited to RVs which use direct current (DC Power); this is the same type of power that is generated by the solar panel charger.
When the energy generated by the solar charging panel has to be used in circumstances calling for alternating current (AC Power), such as in your home, then a slight loss in energy is suffered as a consequence.

The first instance of solar power being tested and used was at The Natural Bridges Monument in the February of 1980, but it was not until May of that year when the whole system came into operation.

What does the future hold for Solar Panel charger power? Well for a start, solar power has great expectations for providing all of our energy needs and also solves some of the problems associated with the greenhouse emission gasses.

Some of the plans in consideration involves the use of solar panel arrays, about a kilometre in size, orbiting in space, beaming their power down to earth to be picked up by a number of ground based antennas, where the solar energy would be converted into usable electricity.
