Q:Solar panel wiring trouble.?
You are probably wiring them incorrectly: with the positive on panel A connected to negative on panel B; and the negative on panel A connected to the positive on panel B. If you want then connected in parallel, connect the positive on panel A to the positive on panel B and the negative on panel A connected to the negative on panel B. But you will only get vdc. You can't get .5 volts from two volt sources. You can get 2 volts by connecting the panels in series.
Q:have you ever installed solar panels for your home?
yes. Its pretty simple connection. It does save money on electricity.
Q:how much energy does a 70x70 sq ft area of solar panels collect?
This question is too generalized to answer. Are you australia? If so ergon buys the power back at 45cents a KWH which is 3 times what they sell it for.(this is guaranteed for 20years) We have a 2.4kw system and it will take approx 5years to pay itself off. Once carbon trading is in full swing electricity costs are going to go up by 40%, then obviously it will take approx half the time.
Q:Reflectors or mirrors around the solar panels.......?
You could (an example of concentrating sunlight is called cloud gain, where the edge of a cloud will intensify sunlight as it passes between the sun and your panels), but that will make your panels run hotter and will probably reduce their life. It's better from a system design standpoint to simply get another panel or two. DK
Q:Why are solar panels so expensive?
They are made of costly materials and require expensive manufacturing processes. The market has been limited because people are not catching on very well to the new idea. The more we buy and use solar panels, the more the price will come down.

Q:What is the principle of solar panels to convert solar energy into electricity?
When the light is irradiated on the surface of the solar cell, a part of the photon is absorbed by the silicon material; the energy of the photon is transferred to the silicon atom, so that the electrons are moved and the free electrons are formed on both sides of the P-N junction to form a potential difference. When the circuit is used, the current will flow through the external circuit to produce a certain output power. The essence of this process is the process of converting the energy of the photon into electrical energy.
Q:What is so great about solar panels ?
Solar panels saves energy (electricity) because the power comes straight from the sun and stuff
Q:New Prius; Solar panles a good design?
The solar panel option is for running a ventilation system while the Prius is parked outdoors, so the sun won't heat up the interior. Personally I think it's a good idea, especially if your car has leather seats-- There is nothing more unpleasant than getting into a car with leather seats that has been sitting in the sun for hours with the windows closed. Many a people in shorts have their thighs scalded on the leather seats that way. The solar panels are a luxury option, not standard equipment on the Prius. I think luxury cars like Mercedes and Cadillacs with leather interiors can use a system like that.
