Shop Right And Minimize The Cost Of Solar Panels
Solar panels are expensive, but you can find them from little known alternative sources and build your own system to save thousands.
When you have solar power installed in your home, the panels easily make up half the total cost. With the average system costing around $50,000, this is a substantial amount . Solar panels are simply an enclosed chain of individual solar cells that collect the energy and pass it along through the system. Purchasing used panels or making your own out of individual cells you buy are both good alternatives to buying them new.
Using this approach a consumer can start building their system as small as they’d like - even with just 1 panel, and then add onto it over time.It helps to understand a few basic concepts before shopping for used panels or cells.
Don’t buy anything until you know what you are getting because there are differences in the amount of energy a panel, or cell can produce even when they are the same size.
Cell and panel ratings for wattage and amps determine the amount of power each is capable of producing. In prior articles on the cost of solar panels, we discussed how to estimate the amount of power you need for a given project.
Age, quality and cell condition also play a part in this equation when considering used panels or cells. This is because newer technologies are more energy efficient than older technologies. Solar cells also have an expected age rating once placed into use, so an old cell that has been used more will have a lower capacity than an identical cell that has never been used.
None of this necessarily makes them bad to purchase, you just have to understand what the output will be in relation to your project goals. As an example, you can often buy individual cells from the manufacturer that have minor defects but are perfectly fine for your project. Build your own panels from these and you will save thousands over the cost of retail market panels. All it takes is some basic tools and a little DIY skill.
The secret is to understand what you are getting and what the output will be so you can avoid wasting money on parts that don’t perform as needed. Keep an eye on the dollar cost per watt while you are shopping for parts. This will help keep your project within budget and on track. I like to use $9.00 per watt as a comparison figure. This is what it generally costs to have a solar power system installed by a contractor. When shopping for your materials, try to get as far below that number as possible, but don’t buy parts you can’t use. You might be amazed how low the price is.
With the right guidance, building your own system is surprisingly simple and inexpensive. Homemade solar is becomming more and more popular lately thanks to the documentation now available. If you are considering solar power for your home, you should really check out one of the better do it yourself guides on the market When you consider the amount you can save over a professionally installed system, a good quality, low cost DIY guide is a smart investment.
