A do it yourself kit runs between $200-$600 dollars. Many savvy electricians are getting the skills to help homeowners as they increase their business, and with the prospect that the economy could go into another economic downturn smart homeowners are discovering it pays to be fore-armed especially when many electric companies are installing new meters that could raise current prices by 20.30, and even 50 percent in extreme cases. Yet building a solar panel costs about 150$ while buying one retail costs about 3,000$ and prices are decreasing annually as more people are getting wiser to whats going on. One contractor J.Lynda Blake owner of Boston’s Narman Construction says “It’s kind of like when toilets were first installed in homes… people were like what do we need that for... we’ve got an outhouse?”
Home made energy an online DIY site states “When building solar panels, people sometimes think it is much easier to purchase professionally made ones. This is true for sure – it is always easier to just go on and buy an “out of the box” product but here’s the thing. As a rule, “Out of the box” products cost a lot more than products built on your own. “Out of the box” Solar panels can cost you somewhere around 2,000$ to 5,000$ or more. Here’s how much it cost to build solar panel:
Solar cells 74$
Tools (screws etc.) 25$
Jones Plugs 6.57$
Silicon Caulk 4.45$
Diodes (100) 1$
Misc. (paint, wires)
All of these parts are available via ebay or your local store for about 150$. And how much does this save you? 100′s of dollars per month according to HomeMadeEnergy.org a home energy kit retailer. But many choose to go with their own local electricians who have learned the installation at many local community colleges. In Boston Roxbury Community College is a central educational institution with the goal of educating people in new green technologies. How is a solar panel made you ask first you have to purchase the solar cells as these are not something readily available in home depot going online would be your best bet and prices are very good as there are so many manufacturers worldwide. ”A solar electric module or solar (PV) panel consists of sheets of highly durable, low reflective, tempered glass with an aluminum frame and with individual solar cells affixed to the inner surface of the glass. Individual solar cells are wired in series strings to increase the panel's voltage and the series strings are again wired in parallel to increase the panel's current output. The back of the photovoltaic panel is protected by another sheet of tempered glass or a different type of long-lasting material. The output of the series and parallel connections are passed through the protective backing and then wired to a weather proof junction box mounted to the back of the panel. The panel's output connections are made in the junction box and this is where you to draw the electricity from the panel. A PV panel may also consist of several modules wired together, and is then also called an array of solar modules. photovoltaic panels can also be wired in series or parallel to increase the total current or voltage output needed to power your home. Solar panels are placed in your yard or on your rooftop where they can get the most amount of sun during daytime.”
The electricity from the PV panels flows as direct current (DC) at a low voltage, but household appliances require alternating current (AC) at a higher voltage. An inverter is then used to convert the DC (usually about 12 volts) to AC (110 volts or 220 volts, depending on where you live). No electricity is generated when the sunlight is not available at night or on overcast days. Special batteries (called deep-cycle batteries) are used to store surplus electricity during sunny days, and electric power is obtained from the batteries when the sun is not available. A charge controller is required to ensure that the batteries aren't overcharged or drained too much. This will ensure that the battery lasts longer.
Many Do it yourself step by step guides are available and with instructions so easy a kid in high school could accomplish the task as part of the science fair. The best thing is in many states electric companies will have to send you checks monthly by law for any excess energy you create that is added to their grid many people receive checks of up to fifty dollars a month from electric companies instead of bills. The federal government even has tax incentive refunds of up to 2000.00 for those homes who utilize solar panels. So it is entirely possible you can have improved energy efficiency a reduced bill and extra income for FREE! And just in case that isn’t enough incentive if President Barack Obama gets a second term it is likely the White House will go solar as well!
