Recon gurable solar converter for photovoltaic battery

Leave a comment MIT researchers have developed a simple procedure for making a promising type of solar cell using lead recovered from discarded lead-acid car batteries — a practice that could benefit both the environment and human health.

You can hook the light up to a solar-powered battery system, or you can remove the light altogether and replace it with a stand-alone solar fixture. The first option costs more, but it's the way to go if you like your present fixture or want to convert an array of lights.

The Stand-Alone Option Although it isn't really a conversion, replacing your electric light with a stand-alone solar light deserves some consideration.

Solar light fixtures are inexpensive and easy to install. They draw energy from a photovoltaic panel, and although this is usually attached to the fixture, you can buy kits that include fixtures, panels and wire to connect them.

These kits allow you to place the panel in a sunny location while keeping the fixture in a shady spot near the house or in the garden. The main problems with standalone fixtures are that they aren't as bright as electric lights and that they gradually grow dimmer during the night as the charge on their batteries dies.

However, during the early part of the night, when outdoor activity peaks, they provide enough light to illuminate a walkway or garden, and they do it for an affordable price that fits most budgets.

Sciencing Video Vault Converting Your Volt Fixture to Solar If you like your outdoor light fixture, but you don't like paying for electricity, it's possible to convert it to solar without replacing it. To do this, you'll need a few system components besides the solar panels that will ultimately provide the power.

It's also a good idea to replace the incandescent bulb in your fixture with an LED bulb. LEDs can produce the same amount of illumination as incandescents and use a fraction of the electricity. System Components When setting up the system, the best place to start is at the battery bank.

After you size the battery, you'll know how much output you need from the solar panels.

Battery Bank — You need at least one deep cell battery to power your lights, and it should be rated for at least amp hours to allow the system to compensate for cloudy days and to power the inverter. The more charge the battery can hold, the longer it will power your lights, but keep in mind that a bigger battery needs a bigger solar array to keep it charged.

Solar Panels — Virtually any solar panel with an output of 5 watts or more will charge the battery, but larger panels charge the battery more quickly, and that's important. If you have a Ah battery and get about eight hours of sunlight a day, the panel output should be at least watts to ensure the battery charges fully during the day.

You can use a single watt panel or any combination of identical smaller panels wired in series. For example, you can use two watt panels or four watt ones.

Charge Controller — A charge controller isn't a requirement, but it's strongly recommended. When you connect it between the panels and the battery, it prevents the battery from overcharging. You can wire your existing light directly to the inverter.

A watt inverter should provide more than enough power for your light without quickly draining the battery. Setting Up the System The battery needs to be protected from the elements, so it should be in an enclosure, such as a shed. The panels, on the other hand, should be located in a place that maximizes the amount of sun they receive.

After you install the panels, connect them to the charge controller, which should be close to the battery, using low-voltage wire.

Next, connect the charge controller to the battery using battery cables. Finally, connect the inverter — which should also be located close to the battery — with battery cables.

When these components are placed and connected, you have power, and all that's left to do is to connect the light to the inverter.

Since most inverters have receptacles, the easiest way to do this is to disconnect the light fixture from the electric panel, run a length of or gauge outdoor cable from the light to the inverter, connect one end to the light, install a plug on the on the other end and plug it into the inverter.

After a full day of sunshine, your light should continue to shine brightly at night.A new converter, for photovoltaic battery applications, called Reconfigurable Solar Converter (RSC), uses only single-stage three phase grid-tie solar PV converter to perform dc/ac and dc/dc.

photovoltaic (PV) system with a battery in this paper. The PV system and the battery are connected to the unidirectional port and the bidirectional port of the converter, respectively. A maximum power point tracking (MPPT) algorithm is designed for the PV panel to generate the maximum power when solar radiation is available.

Solar Panels – Virtually any solar panel with an output of 5 watts or more will charge the battery, but larger panels charge the battery more quickly, and that's important. If you have a Ah battery and get about eight hours of sunlight a day, the panel output should be at least watts to ensure the battery charges fully during the day.
