The first question that many new solar panel buyers ask is: how many panels do I need? First things first, let’s review some basic terms electricity terms you’re going to come across when shopping for residential solar power.
RV solar panels are a component of an electrical system which converts light from the sun to electricity. This electricity is used to charge the RV batteries and are capable of running all the basics in your RV, including the lighting and appliances. On great advantage of using RV solar panels is that you can travel to a wider variety of locations. No longer will you have to worry about finding a source of power for your vehicles when you travel. As long as the sun is shining, you will be taking your power with you.
You can choose to attach the mounting hardware directly to the roof’s rafters or use wooden blocks that span multiple rafters to secure the hardware. You want to provide a strong foundation for the panels in the event of strong winds. Avoid mounting solar panels el paso to the plywood sheathing of the roof, as this will not create a strong enough foundation and you risk damage to both the panels and your roof if you do so.
All the variables that have been mentioned above could affect, one way or the other, the number of necessary solar panels. As a rule of common sense, the larger the pool, the more solar panels you need. The size of the solar panel and the watts it produces can also influence this calculus.
If you wish to choose used solar panels, it could require you more technical connections. You need to make a research first on the second-hand product that you’re going to buy. This is to assure that you will get the effective yet affordable product possible. Buying such kind of panels most commonly doesn’t have installation services. Most probably, you need to hire a professional to install the panels or do it yourself. If you choose to make it yourself, you can look at some DIY solar panels guide online or on video tutorials. You can find used solar panel parts in many places online or on your local classifieds.
To determine what your needs are for, remember power consumption is measured in Watts per hour. You need to calculate the energy needed for all the appliances and devices you will be using and add them all together. Then determine the hours you will be using them. For instance; if a fluorescent light consumes 15 Watts per hour, multiply that by the number of hours it will be used. If you will have it on for 2 hours, you will need 30 Watts. By calculating all the devices you intend to use, you can determine your needs in solar panel size.
Now you need to wire the cells together, and for this you are going to need solder, flux, and a soldering iron. These cells have to be linked in a series, as well as connected together. All of the cells have to be connected together in a series. Nine cells make up a roll, so solder this first roll together, then the next three. Now the electrodes on the negative side, which have a bluish surface, need to be soldered to the positive contact points on the next cell.
For simple reference in regards to the difference between parallel and series wiring, just remember that parallel wiring = more amps, and series wiring = more volts. With a sound understanding of the differences between parallel and series solar installations, you are now ready to design and build your own solar panel system.
