No. They are not bright enough and they dont stay "charged" for long periods of time generally. They are useful in places like cemetaries and on sidewalks and such because they are usually only needed for the dusk and early hours of darkness where airport runways are used all hours

1. Outdoor solar lights not very bright why?

Usually they only have one LED bulb in them, one LED bulb is not going to give off much light, and it depends on the reflector inside as well, more LEDs more light, and also there are different LEDs that give off different strengths of light

2. list some advantages and disadvantaged to solar power?

There are many advantages of solar energy. Just consider the advantages of solar energy over that of oil: Solar energy is a renewable resource. Although we cannot utilize the power of the sun at night or on stormy, cloudy days, etc., we can count on the sun being there the next day, ready to give us more energy and light. Oil, on the other hand, is not renewable. Once it is gone, it is gone. Solar cells are totally silent. They can extract energy from the sun without making a peep. Now imagine the noise that the giant machines used to drill for and pump oil make! Solar energy is non-polluting. Of all advantages of solar energy over that of oil, this is, perhaps, the most important. The burning of oil releases carbon dioxide and other greenhouse gases and carcinogens into the air. Solar cells require very little maintenance (they have no moving parts that will need to be fixed), and they last a long time. Although solar panels or solar lights, etc., may be expensive to buy at the onset, you can save money in the long run. After all, you do not have to pay for energy from the sun. On the other hand, all of us are aware of the rising cost of oil. Solar powered lights and other solar powered products are also very easy to install. You do not even need to worry about wires. And here are the disadvantages of solar energy: Solar cells/panels, etc. can be very expensive. Solar power cannot be created at night. As you can see the advantages of solar energy create a much longer list that the disadvantages, and the disadvantages are things that can be improved as technology improves.

3. Where can I find a lighted palm tree?

I agree with going to Michael's. I got mine there a few years back and it is over 5' tall. I did not use solar lights because I wanted a showier look. I wrapped green Christmas lights in the palms and then used a rope light wrapped around the trunk to fit. It does not use much electricity because of the low voltage and you can put it on a timer for the amount of time you want. Wait until they have a 40% off coupon and they will be quite affordable

4. Why aren't my solar lights working?

The two that light are getting the most sunlight. They need more then 6 hours to charge up. Remember, not every day is "sunny"!.

5. Can i keep my solar lights outside all winter long even when it snows?

You can certainly leave them out, but Ni-Cad and Ni-MH batteries, the kind of cells your lights will have in them, tend to not work well in the cold, so I doubt they will work well until the warm weather comes around. You will find they work great once they thaw out; in fact, a clever trick some people use to extend the life of rechargeables is to store them in the fridge in a Zip-Loc bag. Solar cells, light bulbs, and LEDs will not be damaged by the cold. Most battery technology does not work well in the cold, actually; that's one of the reasons it's so bloody hard to get your car started in a Prairie winter.

6. I'm kind of worried about living on my own?

You can put a piece of wood in ledge of the sliding glass door to prevent it from being able to be slid open (this is what a lot of people do). There are also door and window alarms that you can purchase at the store (relatively cheaply) that will go off if one is opened. Make sure that you have blinds or curtains and keep them closed at night and when you are out of the house so that people cannot look in. You can purchase removable batter-powered motion detectors or put out solar lights around the patio (and entrance) if these are private for your unit -- if they are shared, then this is not a feasible option. If the door does not have a deadbolt, ask the landlord if one could be installed for extra security. It can be very scary living on your own for the first time -- this is common. Make sure that you are moving into a safe neighborhood and that you are prepared, just in case anything would happen. Most homes are not burglarized while people are home -- which could help to reassure you at night. Keep a lamp on at night if it makes you feel more secure -- I've done this many of times; in fact, it's a habit now and it does make me feel better (I've been a single mom for 10 years). Good luck to you. Try not to let fear get the most of you and just try some basic safety around your home. Obviously, do not open the door to anyone you do not know - and make sure that you know who it is if someone knocks on your door at night. I've got friends who know I will not come to the door after dark if they knock, so they better call and tell me they are on my door step. Make sure that your apartment is not in a high-crime area (the local police department can give you this information if you are not sure)... other than that, you should be fine. Congratulations on your new place.
