Choice electrical power sources are most likely the hottest debate matter of the century and within the attempt to enhance the use extent of wind water and sun for electrical power production governments have come up with a legal qualifications to support and motivate their set up. Given that the photovoltaic energy methods are quite highpriced theres no way theyd turn into compulsive a minimum of not until a more affordable answer is discovered. Below the conditions and so that you can help using solar panels Maine authorities for instance have started to consider some essential payments on solar energy. The situation for your solar panels Maine tactic was that from the rebate program.

The geographical specificity on this component of USA enables to get a quite intensive use of photo voltaic vitality for that manufacturing of electrical energy for both house utilities and heating functions. For that reason solar panels Maine authorities declare will small by minor compensate for the populations want for natural and organic fuel support. The incentive packages that the local governmental businesses have come up with cover the utility rebates and the utility loans which means that once you set up a photo voltaic electricity program funds is going to be reimbursed for the residents or even the organizations which have taken up the initiative.

The very first dilemma the solar panels Maine options encountered was that of spending budget limitation. Get for example the year 2005 when the 500000 allotted for the function of rebate was exhausted without covering the desires of all the applicants. Numerous Maine citizens who contributed to your enactment with the solar vitality program in their households needed to wait around for your promised rebate until new funds have been allocated. Over the subsequent two several years solar panels Maine consumers obtained much more rebates than the years just before and the figures are in progress with each and every coming month. It really is only allnatural that one particular would like to advantage through the advantages of noelectricity bill and a tax credit for your solar power investment.

The photo voltaic panels Maine policy finds its spot in a very really complicated and widely spread national latest meant to encourage using choice electrical power sources and also the limitation of pollution. One particular other component thats nevertheless under debate issues the reduction of the fees for your solar panels to ensure theyre able to be more simply available to the common person that has a restricted budget. Tax reduction is only one particular incentive but if lower charges had been practiced all the more photo voltaic panels would be marketed.

Frequently Asked Questions

  1. QUESTION:
    If I use 2 x 50 watt/12v solar panels, how many ampers does my charge controller need to be?
    I will use 2 panels of 50 watts each to charge a car battery off grid and generate enough electricity to recharge cell phones, AAA batteries or 3.5v 400mA batteries for example.

    I would like to know what kind of charge controller and inverter I should get.

    Thanks!

    • ANSWER:
      Your panels should be paralleled. That will yield 12 volts at approximately 8.2 amps (100 watts). Since a car battery is already 12 volts nominal, you should be able to charge the battery directly from the solar array without need for any type of inverter.

      Be sure to put a fuse inline with the solar array and also inline with any device you plan to attach to the car battery. These batteries can deliver massive amounts of current very quickly and can easily start fires if you do not properly fuse your lines.

  2. QUESTION:
    Is it possible to connect 2 - 12V solar panels to charge a 24V e-bike battery?
    I would like to extend my range on my small e-bike and charge the batteries while sitting at the park or enjoying a Starbucks while stationary without a 110V charger.
    Any Ideas? and how many watts would be best?

    • ANSWER:
      Extending your range by the use of solar panels will be awkward at best. The physical size and weight of the panels and inverter would prove to be overwhelming. Carrying an extra set of charged batteries would be somewhat heavy but more sensible.

  3. QUESTION:
    QUestion about portable Solar Panels.. Mine is 12v?
    I have had this 12v portable Solar Panel for my apartment for awhile. Only problem is that I have no balcony and I can barely get enough sun to use it with my Cobra 450 400-800 watt outlet converter. Can someone advise me a better method to use these? Like do I have to get more 12v solar panels? I have a small apartment and use it on one window. Also is it possible for me to buy a portable storage tank to store the energy gathered from the sun by the solar panel?

    • ANSWER:
      How many watts is the panel, and how many watts is the device you are powering and how long is it on a day? Let's say it's a 40W stereo that's on 3 hours a day. 40Wx3hours = 120Watt hours.

      Now let's figure how much power the solar panel makes. If it is a 30W panel and gets 4 sun hours a day (not hours of sun, this is how long it gets the equivalent of a standard test condition), it probably gets closer to 2.5 or 3 sun hours in the winter, depending on where you are. 30W x 4 sun hours = 120Watt hours. Perfect, except there are losses in the system, so you need to figure around 30% loss overall, which brings you to 84wh. That's too small for your load.

      A 12V sealed AGM battery can be used to store the power. You'd also need to calculate the size needed for that.

      There is a calculator available to do a lot of this math for you. You need to figure out your load first, then enter the wh in this calculator. It will tell you what size panel and battery you need. http://www.altestore.com/store/calculators/off_grid_calculator/

  4. QUESTION:
    Where can i buy mini (1v - 12v) solar panels?
    I am doing a project for school and i need to power a 9v DC motor using a solar panel. Does anyone know places i could get these for not to expensive, and how many volts/watts i would need?

    • ANSWER:
      Jameco Electronics carries some small solar panels that may work. They also carry individual cells, so you could make your own panel if you need to.

      The amount of current you will need will depend on the motor you are using and the load it will be required to drive. If you have the documentation for the motor is should list current specifications. You can also hook it up to a power supply through an ampmeter and measure the current drawn by the motor directly.

      You can buy larger panels and complete systems from several other companies as well:
