Used Solar Panels – How To Use Them To Build Cheap DIY Solar Panels

You can build cheap DIY solar panels by salvaging parts from used solar panels. The end result can be very fulfilling. Many hobbyists remarked that they spent only a fraction of what it would otherwise cost them had they bought a comparable solar power system.

It takes a little skill and practice to harvest components from pre-owned or broken solar panels. Yet it is not so difficult that you cannot manage it with basic DIY skills.

You have to free the photovoltaic cells from the base it’s mounted on. After you have done this, check the solar cells for loose connections, broken panels, condensation and damaged diodes. Common problems such as these can potentially cause your solar panels to break down shortly after installation.

If the joints between solar cells are broken or loose, you have to re-solder them. Malfunctioned diodes can be replaced with new ones from your local component store. And if you see broken photovoltaic cells, you will have to source for a similar component to replace it — this can be challenging. Yet you can still make do with the broken cell in case your efforts to replace the broken solar cell fail. There will be reduced power output as a result, but this is not a grave concern.

The array of solar cells is usually mounted on a piece of masonite or acrylic (substrate) board before it is placed into a new solar panel frame. You can discard this substrate after a few years if you intend to replace the solar cells with fresh, new ones.

Using pre-owned solar panels to build DIY solar panels has its pros and cons. The most obvious advantage is the price. Used solar panels can be very cheap and some kind contractors may even give them to you without asking for a single cent. You are also less worried about breaking expensive photovoltaic panels while building your project.

On the other hand, a used solar panel’s lifespan may be significantly shorter. Their power output will also be a little lower compared to when it was new. A loose connection or a fault may hide itself somewhere that escapes your attention. As you build your DIY solar panel, trouble may spring up from these areas. However this can be managed if you’re careful in checking for potential failures.

Overall, harvesting parts from a used solar panels proof to be the best money saving method to build DIY solar panels. The only downside is the additional effort you have to put in. Yet as DIY hobbyists, we tend to take joy in such labor.

Homemade Solar Panels

admin — Thu, 07 Jul 2011 10:00:12 +0000

In recent years, constructing homemade solar panels has become the talk of the DIY community. For the first time in history, do-it-yourself hobbyists are able to construct their own solar panels to generate electricity for their garden lights or automatic gate openers. More experienced hobbyists readily build grid-tied solar power systems that can supply most of their household electricity consumption.

In many people’s mind, homemade solar panels are often perceived as cheap, fragile or makeshift. This is understandable. Without big brand names behind our handicraft, do-it-yourself solar panels are often misunderstood as temporary setups that may break before the week is over.

What people fail to notice is that photovoltaic cells found inside our solar panels are actually reliable units of solar generators manufactured by corporations that adopt world-class production processes.

The DIY hobbyist simply puts different components together so they form a system that generates enough electrical power to run electrical appliances. The reliability of the system lies largely on the photovoltaic cells.

Although it requires a little knowledge on how to use simple tools and constructing simple electrical circuits, building a homemade solar panel is really one of the simplest DIY projects around.

To build a DIY solar panel, the hobbyist builds a shallow, wooden box that provides structural support to house all the necessary components. He then place the solar cells onto a substrate made of masonite or acrylic before attaching it to the base of the shallow box. After that, he prepares a piece of glass or plexiglass to cover up the box. This provides protection from outdoor elements that can harm the components. If necessary, an inverter is used to convert direct current into alternating current so household appliances can use the electricity.

Those of us who aspire to build a simple homemade solar panel can do so within a weekend even if we have no prior experience making one. This is provided we have basic DIY skills to fabricate simple parts as described above to house the components in.

There are, however, a few pitfalls that can cause our homemade solar panel project to come to a screeching halt. Therefore it is useful to get advice and supervision from other hobbyists who are more experienced. Alternatively, you can also get a reliable guide to show you the steps and pitfalls to building homemade solar panels.
